Next, examples of the present application will be described in detail.
An embodiment of the present application provides a communication method, which is applied to any service board in a routing device, and as shown in fig. 1, the method may include the following steps:
s11, when receiving a first LLDP message carrying a single board type of an opposite end service board sent by any one opposite end service board directly connected with the service board, determining the service capacity corresponding to the single board type according to the corresponding relationship between the locally stored single board type and the service capacity.
In this step, the service board and the opposite end service board belong to different routing devices.
In addition, the first LLDP packet in this step is mainly used to notify the service board of the board type.
S12, determining the minimum service capacity of the service capacity corresponding to the single-board type of the service board and the determined service capacities corresponding to the single-board types of all the opposite-end service boards as the service capacity finally used by the service board, and sending the second LLDP packet carrying the service capacity finally used by the service board to all the opposite-end service boards, so that all the opposite-end service boards perform service communication with the service board based on the service capacity finally used by the service board.
In this step, the second LLDP packet is mainly used to notify the service board of the finally used service capacity.
It should be noted that, in this embodiment of the present application, after a routing device to which the service board belongs is powered on, the service board sends a first LLDP packet carrying a single board type of the service board to a corresponding opposite-end service board through each interface directly connected to the opposite-end service board on the service board.
Correspondingly, the service board will also receive the first LLDP packet of the single board type carrying the corresponding opposite end service board, sent by the corresponding opposite end service board through the interfaces. Then, for the first LLDP packet carrying the single-board type of the opposite-end service board, which is received through any one of the interfaces and sent by the opposite-end service board corresponding to the interface, the service board entity may search the service capacity corresponding to the single-board type from the correspondence stored on the service board side first, so that the service board collects the service capacities corresponding to the single-board types of all the opposite-end service boards directly connected to itself, and in combination with the service capacity corresponding to the single-board type of itself, decides the service capacity used by the service board during service communication (i.e., the service capacity finally used by the service board), and notifies all the opposite-end service boards of the service capacity, so that the opposite-end service boards may 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, the communication quality is improved.
In an example, in order to conveniently summarize service capacities corresponding to all the board types of the opposite-end service board, the service board 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 directly connected to the opposite-end service board on the service board, a board type of the opposite-end service board, and a service capacity corresponding to a board type of the opposite-end service board.
For example, initially, the content of the opposite-end service board information table may be null, and once the service board receives, through an interface, a first LLDP packet carrying a single-board type of the opposite-end service board, which is sent by the opposite-end service board corresponding to the interface, the service board may search, from the correspondence, a service capacity corresponding to the single-board type, and add an interface identifier of the interface, the single-board type of the opposite-end service board, and the searched service capacity corresponding to the single-board type to the opposite-end service board information table.
It should be further noted that, in this embodiment of the present application, for the service board, a service capacity table of the service board may also be maintained according to a board number of the service board, initially, the service capacity table is empty, once the service capacity finally used by the service board is determined, the service capacity finally used by the service board is added to the service capacity table, and subsequently, the service board performs service communication with corresponding opposite-end service boards (i.e., all opposite-end service boards directly connected to the service board) based on the service capacity finally used by the service board.
In addition, in order to improve the communication quality, after determining the service capacity finally used by the service board, the service board also sends a second LLDP packet carrying the service capacity finally used by the service board to the corresponding opposite end service board, and the corresponding opposite end service board records the service capacity finally used by the service board and performs service communication with the service board based on the service capacity finally used by the service board.
In one example, in order to ensure the security of the service capacity finally used by the service board, before the service board sends the second LLDP packet carrying the service capacity finally used by the service board to the corresponding opposite service board, the service capacity finally used by the service board may be encrypted 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 connection, it is possible to use,
here, the preset encryption Algorithm may be various encryption algorithms commonly used in the art, for example, an MD5 Message Digest (Message-Digest-Algorithm) Algorithm, etc.
Further, in the embodiment of the present application, as the deployment requirement of the network where the routing device to which the service board belongs is located changes, the opposite-end service board directly connected to the service board may also change, the opposite-end service board may be newly added, and the opposite-end service boards may also be reduced.
Then, for the case that the opposite end service board is reduced, the service board may further perform the following operations:
when the connection relation between the service board and any opposite terminal service board is monitored to be disconnected, if the minimum service capacity in the service capacities corresponding to the single board types of the remaining opposite terminal service boards is not smaller than the service capacity finally used by the service board, the service capacity finally used by the service board is maintained unchanged;
if the minimum service capacity in the service capacities corresponding to the board types of the remaining opposite-end service boards is smaller than the service capacity finally used by the service board, the service capacity finally used by the service board is changed into the service capacity corresponding to the board type of the service board and the minimum service capacity in the service capacities corresponding to the board types of the remaining opposite-end service boards, and a second LLDP message carrying the changed service capacity is sent to the remaining opposite-end service boards, so that all the opposite-end service boards perform service communication with the service board on the basis of the changed service capacity.
It should be noted that, for the service board, when it is monitored that the service board is disconnected from any opposite service board, the related data related to the opposite service board in the opposite service board information table is also deleted.
For the situation that an opposite end service board is newly added, the service board can also execute the following operations:
when a first LLDP message which is sent by a new opposite-end service board directly connected with the service board and carries the veneer type of the new opposite-end service board is received, determining the service capacity corresponding to the veneer type of the new opposite-end 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 board, maintaining the service capacity finally used by the service board 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 board, the service capacity finally used by the service board is changed into the service capacity corresponding to the single board type of the service board and the minimum service capacity in 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 capacity is sent to all the current opposite-end service boards, so that all the current opposite-end service boards perform service communication with the service board on the basis of the changed service capacity.
It should be noted that, for the service board, when receiving a first LLDP packet carrying a new veneer type of the opposite-end service board sent by a new opposite-end service board directly connected to the service board, the service board may specifically search for a service capacity corresponding to the veneer type of the new opposite-end service board from the correspondence, and add an interface identifier of a corresponding interface, the veneer type of the new opposite-end service board, and the service capacity corresponding to the searched veneer type of the new opposite-end service board 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 the routing device 1 in the communication network; the routing device 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. The service board B1 is directly connected with the service board A1 through an interface 21 and directly connected with the service board C1 through an 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 via the interface 25 and to the service board C3 via the interface 26. Of course, other routing devices and other network devices not shown in fig. 2 are also included in the communication network, and are not described one by one here.
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 sends an LLDP packet carrying a respective single board type to an opposite service board directly connected to the service board.
Taking the service board B1 as an example, the service board B1 sends a first LLDP packet of a single board type carrying the service board B1 to the service board a1 through the interface 21, and sends a first LLDP packet of a single board type carrying the service board B1 to the service board C1 through the interface 22.
Correspondingly, the service board B1 also receives the first LLDP packet of the single board type carrying the service board a1 sent by the service board a1 through the interface 21, and receives the LLDP packet of the single board type carrying the service board C1 sent by the service board C1 through the interface 22.
Then, for the first LLDP packet carrying the service board a1, the service board B1 searches for the service capacity corresponding to the service board a's single board type from the locally stored corresponding relationship between the single board type and the service capacity; then, the service board may add the interface identifier (e.g., Port _ ba1) of the interface 21, the board type (e.g., a11) of the service board A1, and the service capacity (e.g., a111) corresponding to the board type of the service board A1 to the initially empty peer service board information table, where the added peer service board information table is shown in the following table one.
| Interface identification | Of the single-plate type | Traffic capacity |
| Port_ba1 | A11 | A111 |
Watch 1
For the first LLDP packet of the single board type carrying the service board C1, the service board B1 searches for the service capacity corresponding to the single board type of the service board C1 from the correspondence between the locally stored single board type and the service capacity; then, the service board may add the interface identifier (e.g., Port _ bc1) of the interface 22, the board type (e.g., C11) of the service board C1, and the service capacity (e.g., C111) corresponding to the board type of the service board C1 to the peer service board information table, where the added peer service board information table is shown in table two below.
| Interface identification | Of the single-plate type | Traffic capacity |
| Port_ba1 | A11 | A111 |
| Port_bc1 | C11 | C111 |
Watch two
Then, the service board B1 determines the minimum service capacity among the service capacity (e.g., B111) corresponding to its own board type, the service capacity (e.g., a111) corresponding to the board type of the service board a, and the service capacity (e.g., C111) corresponding to the board type of the service board C, as the service capacity ultimately used by the service board B1. For example, assuming that the minimum service capacity among the three is a111, the service board B1 will determine a111 as the service capacity finally used by the service board B1, and add the board number (e.g., 101) and a111 of the service board B1 to the initially empty service capacity table, where the added service capacity table is shown in table three below, and the subsequent service board B1 will perform service communication with the service board A1 and the service board C1 respectively based on a 111.
| Plate number of service plate | Service capacity ultimately used by service boards |
| 101 | A111 |
Watch III
Meanwhile, the service board B1 also sends a second LLDP packet 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 B1 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 packet carrying the service capacity finally used by the service board B to the service board C1 through the interface 22, so that the service board C1 records the service capacity finally used by the service board B and performs service communication with the service board B based on the service capacity finally used by the service board B1, thereby ensuring the communication quality.
Next, assuming that the service board B1 detects that the connection relationship between itself and the service board C1 is disconnected at a certain time, in this case, the service board B1 deletes the relevant data about the service board C1 from the opposite-end service board information table two, as shown in the above table one; then, the service board B1 finds that the service capacity (i.e., a111) corresponding to the board type of the remaining opposite service board is not less than the service capacity finally used by the service board B1, maintains the service capacity finally used by the service board unchanged, and continues 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 a first LLDP packet of the single-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 through the interface 27 (not shown in fig. 2), and at this time, the service board B1 searches for a service capacity corresponding to the single-board type of the service board D1 from the correspondence; then, the service board B1 may add the interface identifier (e.g., Port _ bd1) of the interface 27, the service capacity (e.g., D111, which is smaller than a111) corresponding to the board type of the service board D1, the board type (e.g., D11) of the service board D1, and the added service board information table is shown in the following table four.
| Interface identification | Of the single-plate type | Traffic capacity |
| Port_ba1 | A11 | A111 |
| Port_bd1 | D11 | D111 |
Watch four
Then, the service board B1 finds that the minimum service capacity (i.e., D111) of the service capacities corresponding to the single-board types of all the current opposite-end service boards (i.e., the service board A1 and the service board D1) is smaller than the service capacity (i.e., a111) finally used by the service board, in this case, the service board B1 changes the service capacity finally 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 respectively based on D111.
Meanwhile, the service board B1 also sends a second LLDP packet 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 newly used by the service board B1 and performs service communication with the service board B1 based on the service capacity newly used by the service board B1, thereby ensuring the communication quality.
The service board B1 also sends a second LLDP packet carrying the service capacity finally used by the service board B to the service board D1 through the interface 27, so that the service board D1 records the latest used service capacity of the service board B and performs service communication with the service board B1 based on the latest used service capacity, thereby ensuring the communication quality.
It should be noted that, for the communication flows of other service boards in the routing device 1, the routing device 2, and the routing device 3 and the opposite service board directly connected thereto, the communication flows are similar to the communication flows of the service board 1 and the opposite service board directly connected thereto, and are not described herein again.
As can be seen from the above technical solutions, in the embodiment of the present application, for any service board in a routing device, before performing service communication with an opposite service board (different from the routing device to which the service board belongs) directly connected to the service board, a service capacity finally used by the service board is determined through an LLDP packet carrying a single board type from the opposite service board, where 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 board and can 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 make the opposite end service board know the service capacity used by the opposite end service board when the opposite end service board carries out service communication by itself by executing the communication flow, so that the opposite end service board can carry out service communication with the service board based on the service capacity, the problem that part of services cannot be processed is avoided, and the communication quality is improved.
