In addition, wherein said detection messages can be the OAM detection messages.
In addition, the form of said OAM detection messages can be an ethernet frame V2 form.
In addition, after the ethernet port generation loopback that said method also is included in judgement and is detected, close the business of the ethernet port that loopback takes place and send and receive.
In addition, after the ethernet port generation loopback that said method also is included in judgement and is detected: the port to said generation loopback periodically sends detection messages; And as if this port still loopback, then alarm continues; Disappear if detect the loopback of this port, then recover the business transmitting-receiving of this port
The invention allows for a kind of MSTP equipment Ethernet integrated circuit board; Comprise: controller; Be used to generate detection messages, the source address of wherein said each detection messages is the predetermined MAC Address corresponding to this corresponding port of Ethernet, and destination address is the MAC Address of said MSTP equipment itself; The detection messages sending module is used for each port through Ethernet, sends the detection messages corresponding with this port that said controller generates; The detection messages receiver module is used for each port through Ethernet, and receiving destination address is the detection messages of the MAC Address of said MSTP equipment own; Wherein said controller also is configured to the source address according to the detection messages of said reception, discerns its corresponding ethernet port, and judges the ethernet port generation loopback of said detection.
In addition, said controller also is configured to, and after judging the ethernet port generation loopback that is detected, closes the business of the ethernet port that loopback takes place.
In addition, said detection messages sending module also is configured to, and the port of said generation loopback is periodically sent detection messages; And said controller also is configured to: if detect still loopback of this port, then alarm continues; Disappear if detect the loopback of this port, then recover the business of this port.
The present invention has outstanding advantage and effect in terms of existing technologies.Particularly,, judge whether MSTP equipment ethernet port loopback takes place, and it can initiatively find the port loopback, avoid the address vibration through the OAM detection messages; Can in time find the port loopback, the message behind the device port loopback can not transmitted once more, avoids taking place service disconnection, and report and alarm; Guarantee the still normally forwarding of other business that does not produce the loopback port; And after the loopback releasing, can automatic or manual recovery business.
System and method disclosed herein has overcome the shortcoming of above-mentioned prior art in its various embodiment, and has realized the advantage that this system and method can not exist before.
Below will more completely describe the present invention, the preferred embodiments of the present invention be shown in the accompanying drawing with reference to accompanying drawing.But the present invention may be embodied in many other forms, and is not appreciated that and is limited to embodiment described here; It is for disclosure will be detailed and complete that these embodiment are provided on the contrary, and will intactly scope of the present invention be conveyed to those skilled in the art.From start to finish similarly label is all represented similar elements.
Description of drawings
Accompanying drawing 2-6 has shown loopback detection process according to an embodiment of the invention.
Embodiment
Block diagram and flow chart description the present invention below with reference to method according to an embodiment of the invention, device (being system).Be appreciated that each piece of block diagram and flow chart and the combination of the piece in block diagram and the flow chart can be realized by computer program instructions respectively.These computer program instructions can be loaded on all-purpose computer, special-purpose computer or other programmable data processing unit; To produce machine, so that the instruction of on computer or other programmable data processing unit, carrying out produces the device of the block diagram that is used for executive system or flow chart block appointment.
The MSTP equipment Ethernet integrated circuit board functional block diagram that realizes the inventive method is as shown in Figure 1.
The MSTP equipment Ethernet integrated circuit board of Fig. 1 comprises controller, OAM message sending module, OAM message receiver module.
Said controller can generate the OAM detection messages.
According to one embodiment of present invention, the frame format of OAM detection messages is an ethernet frame V2 form, and frame length is 64 bytes.Wherein, the source address and the destination address of frame are particular address: each source address keeps the MAC Address from one group to be chosen, respectively each port of corresponding Ethernet; Destination address is the MAC Address of MSTP equipment itself.
After generating the OAM detection messages, said controller sends it to OAM message sending module.Subsequently, said OAM message sending module sends each OAM detection messages from its corresponding ports.
On the other hand, OAM message receiver module receive to get into the OAM message of this MSTP equipment, and sends said controller to and check.
Controller is checked the OAM message of receiving, judges whether it is the particular detection bag of self sending out; If then according to source address, judge its corresponding port, and report said port to produce the alarm of loopback, and carry out the protection of said port.
In addition, the transmission cycle of OAM message can be provided with as required.
Thus, the present invention provides a kind of MSTP device port loopback detection scheme based on the OAM detection messages, and principle is: OAM message sending module periodically sends the OAM message to each port; MSTP equipment is that the frame of MAC Address own is transmitted to OAM message receiver module and handles to destination address; Controller is checked the OAM message of receiving, judges whether it is the particular detection bag of self sending out; If, report the alarm of port loopback, and carry out port protection then according to source address.
With reference to accompanying drawing 2-6, further describe the concrete steps of the loopback detection process of the present invention's proposition.
Referring to accompanying drawing 2, Router is a router, and 1,2,3,4 is four ethernet ports of MSTP equipment.MSTP equipment Ethernet veneer periodically sends the OAM detection messages to each ethernet port.The source address of said each OAM detection messages keeps the MAC Address from one group selects respectively corresponding each ethernet port 1,2,3,4; Destination address is the MAC Address of MSTP equipment itself.
Referring to accompanying drawing 3, port one, 2,3 normal wherein, port 4 is because ring has certainly taken place in external cause.
Referring to accompanying drawing 4, because outside ring has certainly taken place port 4, MSTP is recycled to former port from the OAM detection messages that port 4 sends by port 4.
Referring to accompanying drawing 5, the said OAM message receiver module of MSTP equipment receives this OAM detection messages, and sends said controller to it is checked.The source address of this message of said controller inspection identifies the ethernet port 4 of its source address corresponding to self MSTP equipment.So, said controller judge mail to port 4 the OAM detection messages by loopback, thereby think that loopback has taken place this port 4.
Then, shown in accompanying drawing 5, controller cuts out the business of this port 4 and sends and receive, and reports the alarm of port 4 loopbacks; The OAM detection messages continues to send to all the other port ones, 2,3.
Referring to accompanying drawing 6, to the port 4 of generation loopback, initiatively regularly continue to send detection messages, as if port 4 still loopback, then alarm continues; If after detecting the loopback disappearance, then alarm is eliminated, and recovers professional forwarding.
Enforcement of the present invention can increase the transmission and the detection of OAM message when data forwarding.Whether be recycled to the port through detecting the OAM detection messages, accomplish the realization of loop back detection.
