Next, embodiments of the present application will be described in detail.
The embodiment of the application provides a communication method, which is applied to any service board in a routing device, as shown in fig. 1, and the method can include the following steps:
s11, when receiving a first LLDP message carrying the single board type of the opposite terminal service board sent by any opposite terminal service board directly connected with the service board, determining the service capacity corresponding to the single board type according to the corresponding relation between the locally stored single board type and the service capacity.
In this step, the service board and the opposite service board belong to different routing devices.
In addition, the first LLDP message in this step is mainly used for informing the board type of the service board.
S12, determining the minimum service capacity of the service capacities corresponding to the single board types of the service boards and the determined service capacities corresponding to the single board types of all opposite-end service boards as the service capacity which is finally used by the service boards, and sending a second LLDP message carrying the service capacity which is finally used by the service boards to all opposite-end service boards so that all opposite-end service boards can carry out service communication with the service boards based on the service capacity which is finally used by the service boards.
In this step, the second LLDP message is mainly used to inform the service board of the service capacity that is ultimately used.
It should be noted that, in this embodiment of the present application, after the routing device to which the service board belongs is powered on, the service board sends, to the corresponding opposite service board, a first LLDP message carrying a board type of the service board through each interface directly connected to the opposite service board on the service board.
Correspondingly, the service board also receives, through the interfaces, a first LLDP message carrying a board type of the corresponding opposite-end service board sent by the corresponding opposite-end service board. Then, for the first LLDP message carrying the board type of the opposite-end service board and received by any interface of the interfaces, the service board can find the service capacity corresponding to the board type from the corresponding relations previously stored on the service board side, so that the service board gathers the service capacities corresponding to the board types of all the opposite-end service boards directly connected to itself, and determines the service capacity used by the service board when performing service communication (i.e., the service capacity finally used by the service board) in combination with the service capacity corresponding to the board type of itself, and notifies all the opposite-end service boards, so that the opposite-end service boards can communicate with the service board based on the service capacity finally used by the service board, thereby avoiding the problem that part of services cannot be processed and improving the communication quality.
In one example, in order to collect service capacities corresponding to the single board types of all the opposite-end service boards conveniently, the service boards may maintain an opposite-end service board information table, where the opposite-end service board information table may include information such as an interface identifier of an interface of the opposite-end service board directly connected to the service board, the single board type of the opposite-end service board, and the service capacity corresponding to the single board type of the opposite-end service board.
For example, the content of the opposite-end service board information table may be empty at the beginning, and once the service board receives, through a certain interface, a first LLDP message carrying a board type of the opposite-end service board sent by the opposite-end service board corresponding to the interface, the service board may search the service capacity corresponding to the board type from the corresponding relationship, and add the interface identifier of the interface, the board type of the opposite-end service board, and the service capacity corresponding to the searched board type to the opposite-end service board information table.
It should be further noted that, in this embodiment of the present application, it is also possible for the service board to maintain a service capacity table according to a board number of the service board, and initially, the service capacity table is empty, once the service capacity of the service board for final use is determined, the service capacity of the service board for final use is added to the service capacity table, and then the service board performs service communication with the corresponding peer service boards (i.e., all peer service boards directly connected to the service board) based on the service capacity of the service board for final use.
In addition, in order to improve the communication quality, after determining the service capacity of the service board for final use, the service board also sends a second LLDP message carrying the service capacity of the service board for final use to the corresponding opposite-end service board, and the corresponding opposite-end service board records the service capacity of the service board for final use and performs service communication with the service board based on the service capacity of the service board for final use.
In one example, in order to ensure the security of transmitting the service capacity that is ultimately used by the service board, before sending the second LLDP message carrying the service capacity that is ultimately used by the service board to the corresponding opposite service board, the service board may encrypt the service capacity that is ultimately used by the service board according to a preset encryption algorithm; and then sending a second LLDP message carrying the service capacity finally used by the service board to the corresponding opposite-end service board. In this context,
here, the preset encryption Algorithm may be various encryption algorithms commonly used in the prior art, for example, a Message-Digest-algorism (MD 5) Algorithm, etc.
Further, in the embodiment of the present application, with the change of the deployment requirement of the network where the routing device to which the service board belongs is located, the peer service board directly connected to the service board may also change, which may increase the peer service board newly, or may reduce the peer service board.
Then, for the case where the peer service board is reduced, the service board may further perform the following operations:
when the connection relation between the service board and any opposite-end service board is monitored to be disconnected, if the minimum service capacity in the service capacities corresponding to the single board types of the rest opposite-end service boards is not smaller than the service capacity finally used by the service boards, maintaining the service capacity finally used by the service boards unchanged;
if the minimum service capacity in the service capacities corresponding to the single board types of the remaining opposite-end service boards is smaller than the service capacity finally used by the service boards, the service capacity finally used by the service boards is changed into the minimum service capacity in the service capacities corresponding to the single board types of the service boards and the service capacities corresponding to the single board types of the remaining opposite-end service boards, and a second LLDP message carrying the changed service capacities is sent to the remaining opposite-end service boards, so that all the opposite-end service boards carry out service communication with the service boards based on the changed service capacities.
It should be noted that, for the service board, when the service board is monitored to be disconnected from any peer service board, relevant data about the peer service board in the peer service board information table is deleted.
For the situation that the opposite terminal service board is newly added, the service board can also execute the following operations:
when a first LLDP message carrying the single board type of the new opposite terminal service board is received, which is sent by the new opposite terminal service board directly connected with the service board, determining the service capacity corresponding to the single board type of the new opposite terminal service board according to the corresponding relation;
if the minimum service capacity in the service capacities corresponding to the single board types of all the current opposite-end service boards is not less than the service capacity finally used by the service boards, maintaining the service capacity finally used by the service boards unchanged;
if the minimum service capacity in the service capacities corresponding to the single board types of all the current opposite-end service boards is smaller than the service capacity finally used by the service boards, the service capacity finally used by the service boards is changed into the minimum service capacity in the service capacities corresponding to the single board types of the service boards and the service capacities corresponding to the single board types of all the current opposite-end service boards, and a second LLDP message carrying the changed service capacities is sent to all the current opposite-end service boards, so that all the current opposite-end service boards carry out service communication with the service boards based on the changed service capacities.
It should be noted that, for the service board, when receiving the first LLDP packet carrying the board type of the new opposite-end service board sent by the new opposite-end service board directly connected to the service board, the service capacity corresponding to the board type of the new opposite-end service board may be specifically searched from the correspondence, and the interface identifier of the corresponding interface, the board type of the new opposite-end service board, and the service capacity corresponding to the searched board type of the new opposite-end service board may be added to the opposite-end service board information table.
The above communication method is described in detail with reference to specific embodiments.
As shown in fig. 2, it is assumed that a service board A1, a service board A2, and a service board A3 are provided in a routing device 1 in a communication network; the routing equipment 2 is provided with a service board B1, a service board B2 and a service board B3; the routing device 3 is provided with a service board C1, a service board C2, and a service board C3. Wherein, the service board B1 is directly connected with the service board A1 through the interface 21, and is directly connected with the service board C1 through the interface 22; the service board B2 is directly connected with the service board A2 through an interface 23 and is directly connected with the service board C2 through an interface 24; the service board B3 is directly connected to the service board A3 through the interface 25, and is directly connected to the service board C3 through the interface 26. Of course, other routing devices and other network devices, which are not shown in fig. 2, are also included in the communication network, and will not be described in detail herein.
After the routing device 1, the routing device 2 and the routing device 3 are powered on, each service board in the three routing devices can send an LLDP message carrying respective single board types to the opposite service boards directly connected with the service boards.
Taking the service board B1 as an example, the service board B1 sends a first LLDP message of a board type carrying the service board B1 to the service board A1 through the interface 21, and sends a first LLDP message of a board type carrying the service board B1 to the service board C1 through the interface 22.
Accordingly, the service board B1 also receives the first LLDP message of the board type carrying the service board A1 sent by the service board A1 through the interface 21, and receives the LLDP message of the board type carrying the service board C1 sent by the service board C1 through the interface 22.
Then, for the first LLDP message carrying the board type of the service board A1, the service board B1 searches the service capacity corresponding to the board type of the service board a from the corresponding relationship between the locally stored board type and the service capacity; then, the service board may add the interface identifier (for example, port_ba1) of the interface 21, the board type (for example, a 11) of the service board A1, and the service capacity (for example, a 111) corresponding to the board type of the service board A1 to the initially empty opposite service board information table, where the added opposite service board information table is shown in the following table one.
| Interface identification | Veneer type | Service capacity |
| Port_ba1 | A11 | A111 |
List one
Aiming at a first LLDP message carrying the single board type of the service board C1, the service board B1 searches the service capacity corresponding to the single board type of the service board C1 from the corresponding relation between the locally stored single board type and the service capacity; then, the service board may add the interface identifier (for example, port_bc1) of the interface 22, the board type (for example, C11) of the service board C1, and the service capacity (for example, C111) corresponding to the board type of the service board C1 to the opposite service board information table, where the added opposite service board information table is shown in the following table two.
| Interface identification | Veneer type | Service capacity |
| Port_ba1 | A11 | A111 |
| Port_bc1 | C11 | C111 |
Watch II
Thereafter, the service board B1 determines the minimum service capacity among the service capacity (e.g., B111) corresponding to the own board type, the service capacity (i.e., a 111) corresponding to the board type of the service board a, and the service capacity (i.e., C111) corresponding to the board type of the service board C as the service capacity finally used by the service board B1. For example, assuming that the smallest traffic capacity among the three is a111, the traffic board B1 determines a111 as the traffic capacity that the traffic board B1 finally uses, and adds the board numbers (e.g., 101) and a111 of the traffic board B1 to the traffic capacity table that is initially empty, and the added traffic capacity table is shown in the following table three, and the subsequent traffic board B1 performs traffic communication with the traffic board A1 and the traffic board C1 based on a111, respectively.
| Plate number of service plate | Service capacity for end use of service board |
| 101 | A111 |
Watch III
Meanwhile, the service board B1 also sends a second LLDP message carrying the service capacity finally used by the service board B1 to the service board A1 through the interface 21, so that the service board A1 records the service capacity finally used by the service board B1, and performs service communication with the service board based on the service capacity finally used by the service board B1, thereby ensuring the communication quality.
The service board B1 also sends a second LLDP message carrying the service capacity of the service board B for final use to the service board C1 through the interface 22, so that the service board C1 records the service capacity of the service board B for final use, and performs service communication with the service board C1 based on the service capacity of the service board B1 for final use, thereby ensuring communication quality.
Next, it is assumed that at a certain moment, the service board B1 monitors that its connection with the service board C1 is disconnected, in which case, the service board B1 deletes the relevant data about the service board C1 from the opposite service board information table two, as shown in the table one above; then, the service board B1 finds that the service capacity (i.e., a 111) corresponding to the board type of the remaining opposite-end service board is not smaller than the service capacity finally used by the service board B1, maintains the service capacity finally used by the service board unchanged, and continues to perform service communication with the service board A1 based on the service capacity finally used by the service board.
Subsequently, it is assumed that at another time, the service board B1 receives, through the interface 27 (not shown in fig. 2), a first LLDP packet of a board type carrying the service board D1 sent by the service board D1 (belonging to the service board in the routing device 4, not shown in fig. 2) directly connected to the service board B1, and at this time, the service board B1 searches, from the above corresponding relationship, a service capacity corresponding to the board type of the service board D1; then, the service board B1 may add the interface identifier (for example, port_bd1) of the interface 27, the board type (for example, D11) of the service board D1, and the service capacity (for example, D111 and less than a 111) corresponding to the board type of the service board D1 to the above opposite service board information table, where the added opposite service board information table is shown in the following table four.
| Interface identification | Veneer type | Service capacity |
| Port_ba1 | A11 | A111 |
| Port_bd1 | D11 | D111 |
Table four
Thereafter, the service board B1 finds that the smallest service capacity (i.e., D111) among the service capacities corresponding to the board types of all the current opposite-end service boards (i.e., service boards A1 and D1) is smaller than the service capacity (i.e., a 111) that is ultimately used by the service board, in which case the service board B1 changes the service capacity that is ultimately used by the service board to D111, i.e., changes a111 in the above table three to D111, and the subsequent service board B1 performs service communication with the service board A1 and the service board D1 based on D111, respectively.
Meanwhile, the service board B1 also sends a second LLDP message carrying the service capacity finally used by the service board B1 to the service board A1 through the interface 21, so that the service board A1 records the service capacity used by the service board B1, and performs service communication with the service board based on the service capacity used by the service board B1, thereby ensuring the communication quality.
The service board B1 also sends a second LLDP message carrying the service capacity that is ultimately used by the service board B to the service board D1 through the interface 27, so that the service board D1 records the service capacity that is most recently used by the service board B, and performs service communication with the service board D1 based on the service capacity that is most recently used by the service board B1, thereby ensuring communication quality.
It should be noted that, the communication flow of the opposite end service boards directly connected to the other service boards in the routing device 1, the routing device 2 and the routing device 3 is similar to the communication flow of the opposite end service boards directly connected to the service board 1, and will not be described herein.
As can be seen from the above technical solutions, in the embodiments of the present application, for any service board in the routing device, before performing service communication with the directly connected opposite service board (different from the routing device to which the service board belongs), the service capacity of the service board for final use is determined through the LLDP packet carrying the board type from the opposite service board, and the service capacity is supported by the opposite service board; and then, sending an LLDP message carrying the service capacity finally used by the service board to the opposite-end service board so that the opposite-end service board can know the service capacity finally used by the service capacity and communicate with the service board based on the service capacity.
Therefore, under the condition that the service capacity between the service board and the opposite-end service board directly connected with the service board is inconsistent, the service board can enable the opposite-end service board to know the service capacity used when the opposite-end service board performs service communication by executing the communication flow, so that the opposite-end service board can perform service communication with the service board based on the service capacity, the problem that part of service cannot be processed is avoided, and the communication quality is improved.
