There are two main ways to manage access terminal devices: one is to manage the access terminal devices as sub-devices of the access aggregation device, and the other is to assign independent IP addresses to these access terminal devices as independent network elements. manage.

For the first management method, the network management device assigns an IP address to the access aggregation device, the network management device communicates with the access aggregation device, and the access aggregation device manages the access terminal device, and the network management device does not need to assign an IP address to the access terminal device , but the disadvantage of this method is that once a new access terminal device is added, the access convergence device must be upgraded to identify the new access terminal device and then manage the access terminal device. The convergence device itself is not upgraded When necessary, this joint upgrade will cause a waste of human, physical and time resources, which is not allowed by the operator.

For the second management method, since independent IP addresses need to be assigned to access terminal devices as independent network elements for management, these access terminal devices will occupy a large amount of IP address resources. Currently, IPV4 resources are relatively scarce, so this management method Obviously, it cannot meet the requirements of operators; at the same time, after the access terminal device is deployed, it is necessary to manually configure an IP address for the device, and then the network management device can manage the device.

Detailed ways

The method and system for managing access terminal equipment, access aggregation equipment, access terminal equipment, and network management equipment provided by the present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

The equipment involved in the present invention includes access terminal equipment, access convergence equipment, and network management equipment. There are three main application scenarios: the first scenario is that the access terminal equipment is directly connected to the access convergence equipment, see Figure 1 for details; The first scenario is that the access terminal device connects to the convergence device across the network, see Figure 2 for details; the third scenario is the integration of the first two application scenarios, see Figure 3 for details. The difference between the first two scenarios is that in scenario 1, the access aggregation device can discover the existence of the access terminal device through a certain protocol such as the extended OAM protocol or LLDP protocol, and can perform simple management on it and understand the relationship with the access terminal device. way of communication. However, for Scenario 2, the access terminal device and the access convergence device know nothing about each other. The embodiments of the present invention need to consider the different situations of the three scenarios, so as to meet the use requirements of different scenarios.

The management method of the access terminal device provided by the present invention is given below from the side of the access aggregation device, the side of the access terminal device and the side of the network management device respectively.

For the access convergence device side, as shown in Figure 4, the management method for the access terminal device provided by the embodiment of the present invention includes:

Step 401, the access converging device assigns a private network IP address to the access terminal device, and sends the allocated private network IP address to the access terminal device through the private network management channel with the access terminal device, and according to the pre-established One-to-one mapping relationship between private network IP address and global port number, record the global port number mapped to the assigned private network IP address;

In the embodiment of the present invention, the private network IP address is used to uniquely identify a device for each access terminal device in the entire system, but the private network IP address of the access terminal device cannot be seen for external network management devices. But only the global port number of NAPT (Network Address Port Translation) corresponding to the private network IP address can be seen. It uses the global port number to uniquely identify a device, so it is necessary to ensure that the private network IP address and the global port The number is one-to-one mapping. In the embodiment of the present invention, the one-to-one mapping relationship between the private network IP address and the global port number is established in advance, and the NAPT global port number assigned to a certain private network IP address is fixed at any time. , otherwise the network management device cannot uniquely determine a remote device.

Step 402, the access aggregation device receives the management message carrying the private network IP address sent by the access terminal device through the private network management channel, maps the private network IP address in the management message to a global port number, and communicates with the network management device The public network management channel between them sends the management message carrying the global port number to the network management device;

Step 403, the access aggregation device receives the management message carrying the global port number sent by the network management device through the public network management channel, maps the global port number in the management message to the private network IP address, and through the private network management channel, the The management message carrying the private network IP address is sent to the access terminal device corresponding to the private network IP address.

In the embodiment of the present invention, after the access terminal device is powered on and connected to the access convergence device, it will automatically obtain a private network IP address from the access convergence device. The access convergence device supports the NAPT function, so that the network management device can directly pass through The IP address of the access aggregation device cooperates with the NAPT function of the access aggregation device (including the function of converting the private network IP address to the global port number) to complete the management of each access terminal device. This management method does not need to upgrade the access aggregation device after a new access terminal device is added; it can not only effectively reduce the allocation of IP address resources, but also avoid the inefficiency of manually configuring the IP address of the access terminal device.

There are many ways for the access terminal device to obtain the private network IP address from the access convergence device, either by the access terminal device initiating a DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) request, or by the access convergence device Address allocation in response to DHCP requests, or after the access aggregation device discovers the access terminal device based on the extended OAM (Operations Administration and Maintenance) protocol or LLDP (Link Layer Discovery Protocol, Link Layer Discovery Protocol) protocol Actively assign private network IP addresses to access terminal devices.

Preferably, this embodiment assigns a private network IP address to the access terminal device, which specifically includes: when directly connecting to the access terminal device, actively discovering the access terminal device by setting a protocol, and determining that the access terminal device does not have an IP address When configuring, assign a private network IP address to the access terminal device; when not directly connected to the access terminal device, when receiving a Dynamic Host Configuration Protocol DHCP request sent by the access terminal device, assign a private network IP address to the access terminal device .

Of course, when directly connected to the access terminal device, the private network IP address can be assigned based on the DHCP request.

According to the current connection mechanism, when the access convergence device is directly connected to the access terminal device, the access terminal device is connected to the access convergence device through a fixed slot number and a remote device connection. The end device is a first-level remote device, and the second-level remote device is connected to the first-level remote device. The second-level remote device is connected to the access aggregation device through a slot.

In order to meet the one-to-one correspondence between the NAPT global port number and the private network IP address, and at the same time support the complex networking requirements of scenario 3, some restrictions need to be placed on the allocation of IP addresses. Preferably, the private network IP address includes the first address segment , the second address segment and the third address segment, the access aggregation device allocates a private network IP address for the access terminal device, specifically including:

When the access aggregation device is directly connected to the access terminal device, the first address segment of the private network IP address assigned to the access terminal is the slot number used by the access aggregation device to connect to the access terminal device, and the second address segment It is the second-level remote device number used by the access aggregation device to connect to the access terminal device, and the third address segment is the first-level remote device number used by the access aggregation device to connect to the access terminal device;

When the access convergence device is not directly connected to the access terminal device, the private network IP address assigned to the access convergence device is selected from the specified address pool, and the first address segment of the private network IP address in the specified address pool is The value of is different from the value of the first address segment of the private network IP address used when the access aggregation device is directly connected to the access terminal device.

A convenient and feasible solution is: use 192.168.XXX.XXX as the available private network IP address segment, and use the lower 15 bits of the private network IP address as the assignable address segment, that is, the first address segment and the second address segment and the third address segment occupy the lower 15 bits of the private network IP address, the first address segment occupies 4 bits, the second address segment occupies 3 bits, and the third address segment occupies 8 bits; access aggregation When the device is directly connected to the access terminal device, the allocation method is: slot number (4bit) + second-level remote device number (3bit) + first-level remote device number (8bit). When the access convergence device is not directly connected to the access terminal device, it randomly assigns a private network IP address to the access terminal device from the specified address pool. The address pool consists of private network IP addresses corresponding to the first address segment being 0. That is, when the slot number is 0, it means that it is reserved for the address pool used based on the DHCP request, while other addresses are allocated to the address pool allocated for the remote end based on device discovery. Since the IP address pool allocated based on device discovery and the IP address pool allocated based on DHCP are independent of each other, the requirements of the third application scenario can be met.

The NAPT global port number is 16 bits, the lower 15 bits of the private network IP address are used as the lower 15 bits of the global port number, and the other bits of the global port number are set to fixed bit values, such as setting the highest bit to 1 , so that the one-to-one correspondence between the private network IP address and the global port number can be realized.

As shown in FIG. 5 , in the embodiment of the present invention, there is a public network management channel between the network management device and the access convergence device, and a private network management channel between the access convergence device and the access terminal device.

The management packet received by the access-aggregation device from the network management device includes the IP address and global port number of the access-aggregation device. Therefore, access to the aggregation device needs to complete the conversion of the public network IP address (the IP of the access aggregation device) + port number (global port number) to the private network IP address + port number (well-known port number), and at the same time complete the switching of the management channel . The access aggregation device supports the NAPT function. The NAPT function itself can complete the work from the public network IP address + global port number to the private network IP address + well-known port number, but it cannot complete the switching of the management channel. The switching of the management channel must Guaranteed by another mechanism.

Preferably, for the case where the access terminal device is directly connected to the access convergence device, since the two are directly connected, the private network management channel between the access terminal device and the access terminal device is specified by the access convergence device, so that the management channel can be guaranteed After the handover, the management message can reach the access terminal device. However, if the access terminal device is not directly connected to the access aggregation device, only the private management channel detected by each access terminal device can be used, that is, the access aggregation device determines the private network management channel for receiving the DHCP request. The management channel of each access terminal device is different. In the embodiment of the present invention, when the access aggregation device feeds back the allocated private network IP address, it feeds back the configuration information of the determined private network management channel to the access terminal device, and records the allocated private network IP address and the determined private network management channel corresponding relationship. In this way, the NAPT-translated management message can be transmitted on the corresponding private management channel according to the private IP address of the management message.

The network management device needs to know the global port number corresponding to the private network IP address assigned by the access aggregation for the access terminal device. Preferably, any of the following methods can be used:

1) After the access aggregation device receives the query request sent by the network management device, it will report the global port number mapped to the private network IP address assigned to the access terminal to the network management device through the public network management channel. Specifically, the network management device may send query requests to the access aggregation device at regular intervals.

2) After assigning a private IP address to the access terminal device and recording the global port number mapped to the assigned private IP address, report the global port number mapped to the assigned private IP address to the network management through the public network management channel equipment. That is, according to whether to allocate or not, the method of active reporting is adopted.

3) Receive the management message carrying the private network IP address sent by the access terminal device through the private network management channel, map the private network IP address in the management message to the global port number, and manage it through the public network with the network management device Channel, which sends the management message carrying the global port number to the network management device.

That is, there is no need to access the aggregation device to report. After the access terminal device obtains the assigned private network IP address, it sends a message to the network management device. When the network management device receives the message, it finds that there is no global port in the message. No., save the corresponding global port number, so as to add the device.

The access aggregation device may also notify the access terminal device of the assigned IP address sent to the access terminal by information such as the gateway address and the address of the alarm server.

Figure 6 shows the process of allocating private network IP addresses based on the active discovery mechanism in the embodiment of the present invention, which specifically includes: the access aggregation device continuously detects whether the access terminal device is found, and once the access terminal device is found, it first queries the access terminal device Check whether the remote device has an IP address configuration and a private network management channel configuration. If not, a private network IP address generated based on the topological location and a known management channel configuration will be sent to the remote device immediately. The private network IP address establishes NAPT global port mapping so that the network management center can manage the device. For the private network IP address generated based on the topological location, refer to the above description and will not repeat it here. If the access remote device already has an IP address configuration and a private network management channel configuration, it does not need to be processed. There are two cases where the access remote device has an IP address configuration and the private network management channel configuration. One is that the access remote device is directly managed by the network management device as an independent network element and has been assigned an IP address by the network management device. An access convergence device has allocated a private network IP address to the access terminal.

As shown in Figure 7, the process of allocating private network IP addresses based on the DHCP request in the embodiment of the present invention specifically includes: whether to enable the DHCP Server can be set, and the follow-up process will not be performed until the DHCP request is received and the DHCP Server is enabled, otherwise the process is ended . When a DHCP request message is received and the DHCP Server is enabled, identify the management channel information in the private OPTION in the DHCP request message. Since the access terminal device sends DHCP request messages on all private management channels (that is, sends request messages in all VLAN numbers), the private OPTION in the DHCP request message will carry management channel information. In this way, the access aggregation device can determine the private network management channel of the DHCP request message first received from the access terminal device as the private network management channel of the access terminal device, and the private network management channel of the access terminal device is subject to the network environment. Influence. The DHCP request message also carries the MAC address set by the access terminal, and the access aggregation device allocates a private network IP address for it according to the MAC address and creates a NAPT mapping relationship, thereby recording which devices are assigned a private network IP address and the device mapping The global port number, send a response message after these preparations are completed, and the response message carries the private network IP address and private management channel information.

On the side of the access terminal device, the management method for the access terminal device according to the embodiment of the present invention, as shown in FIG. 8 , includes:

Step 801, the access terminal device receives the private network IP address sent by the access convergence device through the private network management channel;

Step 802, the access terminal device sends a management message carrying the private network IP address to the access aggregation device through the private network management channel, and the destination address of the management message is the network management device;

Step 803, the access terminal device receives the management message carrying the private network IP address sent by the access convergence device through the private network management channel, and completes automatic network management according to the management message.

Preferably, when the access terminal device is directly connected to the access convergence device, before the access terminal device receives the private network IP address sent by the access convergence device through the private network management channel, it also includes: according to the notification of the access convergence device, determining Receive the private network management channel specified by access aggregation.

When the access terminal device is not directly connected to the access aggregation device, before the access terminal device receives the private network IP address sent by the access aggregation device through the private network management channel, it also includes: passing through all private network management channels to the access aggregation device The device sends a DHCP request. That is, the request message is sent within the range of all VLAN numbers, and the private OPTION in the DHCP request message reaching the access aggregation device through the private network management channel will carry the management channel information.

Preferably, when the access terminal device is not directly connected to the access convergence device, it also includes: receiving configuration information of the private network management channel fed back by the access convergence device; Converge private network management channels between devices.

Specifically, the detection cycle can be set. After power-on, the access terminal device periodically sends DHCP request packets within the range of all VLAN numbers, and detects whether the private network IP address and The configuration of the management channel, once the configuration is received, immediately stops the process of sending DHCP request messages to all channels, and does not process any DHCP response messages, and directly uses the configured private network IP address through the access convergence device and the network management The device is connected. If no DHCP response message is received within one sending cycle, it will continue to send in the next sending cycle. Until the private network IP configuration is received or the user manually stops the sending process.

For the network management device side, the management method for the access terminal device in this embodiment, as shown in FIG. 9 , includes:

Step 901, the network management device receives the management message carrying the global port number sent by the access convergence device through the public network management channel, or receives the global port number reported by the access convergence device based on the request or initiative, and the global port number is determined by The access aggregation device is obtained according to the private network IP address allocated for the access terminal;

Step 902: When the network management device determines that the access terminal device corresponding to the global port number needs to be managed, it sends a management packet carrying the global port number to the access aggregation device through a public network management channel.

In the embodiment of the present invention, after the access terminal device obtains the private network IP address, the network management device can manage the access terminal device through the SNMP protocol through the IP address of the access convergence device + the global port number. The SNMP management message is sent from the network management device and carried on the public network management channel. The management message will carry the IP address of the access aggregation device and the global port number representing the access terminal device. After being transformed by the NAPT function on the access aggregation device, the management message carries the IP address of the access terminal device and the port number of the well-known SNMP protocol, and is carried on the private network management channel to be sent to the access terminal device.

Before the implementation of the embodiment of the present invention, the management of access terminal equipment required an independent IP address, and construction personnel were required to manually configure IP addresses for the equipment on site, which greatly wasted precious IP address resources and seriously consumed human resources. , using the embodiment of the present invention, the construction personnel only need to connect the equipment correctly when installing the equipment, without any configuration, and the management personnel do not need to assign any addresses for each access terminal equipment, only need to check the access terminals used to manage these Access to the aggregation device can obtain the private network IP address + global port number for managing these access terminals, so that these devices can be managed, which saves time and effort, and is more convenient and quick.

Based on the same inventive concept, the embodiment of the present invention also provides an access aggregation device, an access terminal device, and a network management device.
