Fig. 2 obtains network element annexation flow chart for another preferred embodiment of the present invention.
Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
In the frame structure of propagating in optical fiber that data comprised, be respectively arranged with two kinds of expenses, wherein a kind of is section overhead, and another kind is a path overhead.Section overhead is that guarantee information is normally moved and necessary additional byte, be mainly used in operation, management that frame synchronization and network are provided, section overhead specifically comprises RSOH (RSOH) and MSOH (MSOH), comprise J0 among the RSOH again, J0 is a message that comprises some bytes, be used to check the continuity of optical network data passage, i.e. the connectedness of the fine cable of each bar in the optical-fiber network.
In actual applications, after the physical connection of optical-fiber network networking is finished, all of the port on all veneers that just all network elements comprise in connected the whole network of operational administrative center issues J0, after the port of each network element is received the J0 that the operational administrative center issues, the port of each network element sends corresponding J0 with regard to beginning ceaselessly to the port of connected opposite end network element, simultaneously, the port of each network element is also receiving the J0 that the port of coupled opposite end network element sends over always, in order to check the continuity of optical network data passage.Each network element all is kept at the J0 that receives in the data-storage system of self, and the J0 that receives with certain port on current certain veneer cover before the J0 that receives of this port on this veneer once.
The data that comprise certain character length among the J0.Generally speaking, when the physical connection of optical-fiber network networking has just been finished, the J0 that each network element of mind-set issues in the operational administrative comprises one section identical default data, then under the normal condition, the J0 that each transmitting terminal network element sends and its opposite end network element that receives all should be identical to the data content that J0 comprised of its transmission; Simultaneously, the J0 that each network element will be handed down in the operational administrative center backs up portion respectively, is stored in the data-storage system of self.
Certain port of receiving terminal network element is judged its J0 that receives constantly, if the transmitting terminal network element that the receiving terminal network element receives has identical data content to the current J0 of its transmission with the preceding J0 that once receives, the receiving terminal network element thinks that then the data channel continuity between this port and the opposite end network element is no problem; Otherwise, the receiving terminal network element thinks that then the data channel continuity between this port and the opposite end network element has problems, as: fine cable fault even disconnected fibre etc., at this moment, this receiving terminal network element will send alarm to the operational administrative center, is connected and may has problems with fine cable between the network element of opposite end to inform operational administrative center self.
In the optical-fiber network in early days, network element generally can't be changed the J0 data content voluntarily according to the order at operational administrative center, and J0 data content change operation is at this moment mostly independently finished by the operational administrative center.Concrete J0 data content change method is: the former J0 that certain port sent on certain transmitting terminal network element piece veneer is extracted at the operational administrative center from the data-storage system of self, and the data content that this former J0 comprises changed, will finish this port on this veneer that new J0 after the data content change is issued to this transmitting terminal network element again.This port is after receiving the new J0 that the operational administrative center issues for it, and former J0 is just covered by new J0, and after this, this port just becomes new J0 to the J0 that the opposite end network element sends, and no longer is former J0.
Along with the development of optical-fiber network, can just be used widely according to the network element of new generation that the J0 data content is changed in the order at operational administrative center voluntarily.When a data content among the former J0 that certain port sent on the transmitting terminal network element piece veneer will be changed in the operational administrative center, this network element of mind-set issues a related command in the operational administrative, orders this network element that the specific data content among the former J0 that certain port sent on certain piece veneer is necessarily changed.After this network element is received relevant change order, just the data content among the former J0 that certain port sent on certain piece veneer is changed, changed former J0 into new J0, after this according to this order, this port of this transmitting terminal network element just becomes new J0 to the J0 that the opposite end network element sends, and no longer is former J0.
As seen, the data content that comprises among the J0 that the operational administrative center is sent a transmitting terminal network element port is at any time changed, and the J0 before the data content change can be called former J0, and the J0 after the data content change is called new J0.The method of J0 data content change has two kinds substantially: a kind of is that former J0 is independently changed at the operational administrative center, will finish this port that new J0 after the change is handed down to this network element again; Another kind is that the mind-set network element issues a J0 data content change order in the operational administrative, and network element carries out corresponding change according to this order to the former J0 that this port sends, and makes it become the new J0 that finishes after data content is changed.
For second kind of J0 data content change method, specific practice among the present invention is: after each network element of mind-set issues search command in operational administrative, the transmitting terminal network element that can change the J0 data content voluntarily is just among the former J0 that certain port sent on its certain piece veneer, add transmitting terminal network element position information, described transmitting terminal network element position information specifically comprises: the address of this transmitting terminal network element and send veneer number and the port numbers of above-mentioned former J0.After former J0 is added into above-mentioned correspondence position information, just think to be modified to be new J0.At this moment, the transmitting terminal network element is exactly described new J0 to the J0 that coupled opposite end network element sends, and no longer be former J0, at this moment opposite end network element can be thought the receiving terminal network element, when just having comprised the transmitting terminal network element among the new J0 that this receiving terminal network element is received and having sent this new J0, transmitting terminal network element corresponding position information.
After receiving new J0, the positional information that can change the transmitting terminal network element that comprises among the new J0 that the receiving terminal network element of J0 data content just receives it voluntarily is saved in the connection relation list of self, concrete preserving type is: the positional information of the transmitting terminal network element that comprises among the new J0 that the receiving terminal network element will be received and self-position information common storage are in the same address of the connection relation list of self, and the receiving terminal positional information of described receiving terminal network element self comprises: the address of this receiving terminal network element and receive veneer number and the port numbers of above-mentioned new J0.Different with said network element, some network element can't be changed the J0 data content voluntarily according to the order at operational administrative center, simultaneously do not have connection relation list yet, and then just the transmitting terminal network element position information that comprises among the new J0 that receives can't be stored in the connection relation list yet.
After each receiving terminal network element of mind-set in the operational administrative issues querying command, in receiving each receiving terminal network element of querying command, each receiving terminal network element of preserving connection relation list sends to the operational administrative center with the connection relation list of its preservation, and all connection relation list that the operational administrative center then will be received are stored in the connection relation list of self.When each the receiving terminal network element that does not have connection relation list is received querying command, this class receiving terminal network element just sends to the operational administrative center with the current new J0 that receives separately, and the transmitting terminal network element position information that comprises among each new J0 that the operational administrative center then will be received and corresponding receiving terminal network element position information common storage are in the same address of the connection relation list of self.The described receiving terminal network element position information corresponding with the transmitting terminal network element comprises: receive the receiving terminal network element address of the new J0 of this transmitting terminal network element and receive veneer number and the port numbers of described new J0.
By the above as can be known, in the middle of the network element of using that optical-fiber network comprised, two kinds of different types are arranged at present.Wherein a kind of network element can be changed the J0 data content voluntarily according to the order at operational administrative center, make J0 become new J0 by former J0, also the specific data content among the new J0 that can will receive according to the order at operational administrative center is stored in the connection relation list of self; Another kind of network element then can't be changed the J0 data content voluntarily according to the order at operational administrative center, simultaneously, this kind network element is not preserved connection relation list, just can not preserve the specific data content among the new J0 that receives according to the order at operational administrative center yet.
Below just at these two kinds of dissimilar network elements, reach specific embodiment in conjunction with the accompanying drawings the inventive method further described.
At first, the network element at changing the J0 data content according to the order at operational administrative center voluntarily describes the inventive method.
Embodiment one:
Referring to Fig. 1, Fig. 1 obtains network element annexation flow chart for a preferred embodiment of the present invention, and this flow process specifically may further comprise the steps:
After the transmitting terminal network element was finished above-mentioned J0 data content change, the J0 that the transmitting terminal network element is sent was former J0 no longer just, but new J0.The transmitting terminal network element will be before the same with change J0 data content, be sent completely the new J0 of data content change always, after the opposite end receiving terminal network element that links to each other with this transmitting terminal network element is received current new J0, the new J0 that receives of contained this port of this veneer once before using new J0 that contained certain port of current certain veneer receives equally and covering.At this moment, can think that the opposite end network element that links to each other with the transmitting terminal network element that receives this new J0 is the receiving terminal network element.In fact, in the two-way fine cable of using at present, be connected with two optical fiber between certain port of a network element veneer and certain port of another network element veneer, this two follows optical fiber to be used for the sending and receiving signal by network element respectively.Each network element is when connected opposite end network element sends new J0, and also at the new J0 that receives from the opposite end network element, that is: each network element sends the new J0 of self both as the transmitting terminal network element; As the receiving terminal network element, receive new J0 again from the opposite end network element.
Step 103: after each receiving terminal network element is received the new J0 that the transmitting terminal network element sends, in the same address of the connection relation list that transmitting terminal network element position information that just will this new J0 comprises and the positional information of self are kept at self jointly.The transmitting terminal network element position information that described new J0 comprises comprises: send the address of this new J0 network element and veneer that this transmitting terminal network element sends this new J0 number and port numbers.The self-position information of described receiving terminal network element comprises: the address of this receiving terminal network element and receive veneer number and the port numbers of above-mentioned new J0.
Need to prove, when certain port of transmitting terminal network element veneer sends new J0 to certain port of receiving terminal network element veneer, in the same address of the connection relation list that the positional information of the transmitting terminal network element that the receiving terminal network element can comprise this new J0 and the positional information of self are kept at self jointly.Simultaneously, because each network element as the transmitting terminal network element, when opposite end receiving terminal network element sends the new J0 of self, also receives the new J0 from opposite end receiving terminal network element, promptly between a network element port and another network element port, there is the new J0 of two-way transmission.So, when these two network elements when the operational administrative center reports separately connection relation list, two positional informations with identical annexation can be received in the operational administrative center, and just the transmitting terminal network element in the positional information of one of them annexation is the receiving terminal network element in the positional information of another annexation; And the receiving terminal network element in the positional information of one of them annexation is the transmitting terminal network element in the positional information of another annexation.
So, after the connection relation list of each reported by network elements is received at the operational administrative center, both can be in the same address of self connection relation list with the positional information common storage of the positional information of transmitting terminal network element and receiving terminal network element; Also can be with above-mentioned transmitting terminal network element position information and corresponding receiving terminal network element position information together with the transmitting terminal network element positional information common storage when the corresponding receiving terminal network element of the positional information during as the receiving terminal network element is as the transmitting terminal network element in the same address of the connection relation list of self.Like this, in subsequent operation, if in the sending and receiving signal optical fibre between two network elements one or two mistakes have been linked on other network element, optical fiber connection error just can be found according to the network element position annexation of storing in self connection relation list in the operational administrative center, and sends alarm.
In the step 102 of present embodiment because the data content of former J0 is modified, so, receive the new J0 that finishes the data content change when the opposite end network element after, can receive that having the J0 different with former J0 data content sends J0 and alarm because of detecting.In order to prevent this from occurring, the transmitting terminal network element can add a network element search parameter in former J0, make that coupled opposite end receiving terminal network element is received the J0 that comprises this network element search parameter after, can not send J0 alarm; The operational administrative center also can suppress the J0 alarm of all network elements before carry out step 102.
After the step 105 of present embodiment was finished, the operational administrative center can issue former J0 respectively to each port of each network element, made the port of each network element revert to former J0 to the new J0 that the opposite end network element port that links to each other sends; Also can set in advance a time cycle, and by to the setting in advance of network element, after making each network element send new J0 to arrive certain hour length, revert to the former J0 that preserves in the forwarding step 102 automatically.
For ease of the understanding to present embodiment, hypothesis only comprises two network elements in an optical-fiber network below, and each network element only comprises a veneer and a port, as example present embodiment is carried out brief description:
Suppose to be connected with two optical fiber between C port on the B veneer in the A network element and the Z port on the Y veneer in the X network element, be respectively No. 1 optical fiber and No. 2 optical fiber.Wherein, No. 1 optical fiber is specifically designed to from the C port of the A network element B veneer Z port transmission data to X network element Y veneer, No. 2 optical fiber then is specifically designed to from the Z port of the X network element Y veneer C port transmission data to A network element B veneer, and the initial former J0 that is provided with in operational administrative center is arranged in transmission respectively in every optical fiber.
Mind-set A network element and X network element issue search command in operational administrative, and after A network element and X network element are received this order, the A network element just is kept at the former J0 data content that its C port sends earlier in the register of self, again its network element address, B veneer address and C port address are all added among the former J0 of C port transmission, also in former J0, add the network element search parameter simultaneously, and pass through the new J0 of optical fiber after the Z of X network element port sends above-mentioned positional information of adding and network element search parameter No. 1 by the C port; Equally, after the X network element is received search command, the X network element just is kept at the former J0 data content that its Z port sends earlier in the register of self, again its network element address, Y veneer address and Z port address are all added among the former J0 of Z port transmission, also in former J0, add the network element search parameter simultaneously, and pass through the new J0 of optical fiber after the C of A network element port sends above-mentioned positional information of adding and network element search parameter No. 2 by the Z port.
After the C port of A network element was received the new J0 that the Z port of X network element sends, X network element address, Y veneer address and the Z port address that the A network element comprises in just will this new J0 and A network element address, B veneer address and C port address common storage were in the same address of the connection relation list of self; Equally, after the Z port of X network element was received the new J0 that the C port of A network element sends, A network element address, B veneer address and the C port address that the X network element comprises in just will this new J0 and X network element address, Y veneer address and Z port address common storage were in the same address of the connection relation list of self.Mind-set A network element and X network element issue querying command in operational administrative, and after A network element and X network element are received this order, two network elements just report the operational administrative center with the connection relation list that self stores, after the connection relation list of A network element and X reported by network elements is received at the operational administrative center, with the A network element address in the connection relation list of A reported by network elements, B veneer address and C port address and X network element address, Y veneer address and Z port address common storage in the same address of the connection relation list of self; With the X network element address in the connection relation list of X reported by network elements, Y veneer address and Z port address and A network element address, B veneer address and C port address common storage in the same address of the connection relation list of self; The operational administrative center can also with the A network element address in the connection relation list of A reported by network elements, B veneer address and C port address and X network element address, Y veneer address and Z port address together with the X network element address in the connection relation list of X reported by network elements, Y veneer address and Z port address and A network element address, B veneer address and C port address common storage in the same address of the connection relation list of self.
In an optical-fiber network a plurality of network elements are arranged, and each network element is when all comprising a plurality of veneers and a plurality of port, the acquisition methods of network element annexation is identical with the said method principle.
Below, the network element at changing the J0 data content according to the order at operational administrative center voluntarily describes the inventive method.
Embodiment two:
Referring to Fig. 2, Fig. 2 obtains network element annexation flow chart for another preferred embodiment of the present invention, and this flow process specifically may further comprise the steps:
Step 201～202: the operational administrative center suppresses the J0 alarm of all network elements earlier, has the new J0 of change to send the J0 alarm to prevent network element because of receiving data content.Afterwards, the operational administrative center is changed the former J0 of each port in each network element that stores in its data storage system again, corresponding position information is added among each former J0 respectively, former J0 is modified is new J0.Described correspondence position information specifically comprises: the address of this network element and send veneer number and the port numbers of above-mentioned new J0.Then, the new J0 that each each port of network element of data content change will be finished in the operational administrative center is handed down to each port of each network element respectively, and at this moment, the J0 that each each port of network element is sent is former J0 no longer just, but new J0, the network element that sends this new J0 just is considered to the transmitting terminal network element; The network element of receiving this new J0 just is considered to the receiving terminal network element.
Step 203～204: each network element of mind-set issues querying command in the operational administrative, receive that all of the port on all veneers that each receiving terminal network element of this order comprises sends to the operational administrative center with the current new J0 that receives respectively, the operational administrative center can obtain any one to its positional information that sends the receiving terminal network element of new J0 from the data-storage system of self, the positional information of this receiving terminal network element comprises: send the receiving terminal network element address of new J0 and veneer that this receiving terminal network element is received described new J0 number and port numbers to the operational administrative center.
After the new J0 that each receiving terminal network element sends was received at the operational administrative center, just transmitting terminal network element position information that each new J0 is comprised and receiving terminal network element position information were kept in the same address of connection relation list of self jointly.The transmitting terminal network element position information that described new J0 comprises comprises: send the transmitting terminal network element address of this new J0 and veneer that this transmitting terminal network element sends this new J0 number and port numbers to described receiving terminal network element.
Need to prove, because each network element as the transmitting terminal network element, when opposite end receiving terminal network element sends the new J0 of self, also receives the new J0 from opposite end receiving terminal network element, promptly between a network element port and another network element port, there is the new J0 of two-way transmission.So, when these two network elements when the operational administrative center reports the new J0 that receives separately, the operational administrative center is when storage location information, can obtain two positional informations with identical annexation, just the transmitting terminal network element in the positional information of one of them annexation is the receiving terminal network element in the positional information of another annexation; And the receiving terminal network element in the positional information of one of them annexation is the transmitting terminal network element in the positional information of another annexation.
So, after the new J0 of each reported by network elements is received at the operational administrative center, both can be in the same address of self connection relation list with the positional information common storage of the positional information of the transmitting terminal network element that comprises among the new J0 and receiving terminal network element; Also can be with above-mentioned transmitting terminal network element position information and corresponding receiving terminal network element position information together with the transmitting terminal network element positional information common storage when the corresponding receiving terminal network element of the positional information during as the receiving terminal network element is as the transmitting terminal network element in the same address of the connection relation list of self.Like this, in subsequent operation, if in the sending and receiving signal optical fibre between two network elements one or two mistakes have been linked on other network element, optical fiber connection error just can be found according to the network element position annexation of storing in self connection relation list in the operational administrative center, and sends alarm.
Step 205～206: after the information stores of completing place, operational administrative center, issue former J0 respectively, make the port of each network element revert to former J0 to the new J0 that opposite end network element port sends to each port of each network element.Afterwards, the inhibition that is provided with in the operational administrative center cancellation step 201 to all network element J0 alarms.
Embodiment two described methods can be applied to the network element of any kind in the optical-fiber network, and embodiment one described method then can only be applied to change voluntarily according to the order at operational administrative center the network element of J0 data content.
For ease of the understanding to present embodiment, hypothesis only comprises two network elements in an optical-fiber network below, and each network element only comprises a veneer and a port, as example present embodiment is carried out brief description:
