Description
Technical Field
The present invention relates to the field of communications, and in particular, to a communication device.
Background
Conventional small-capacity communication devices, such as routers and the like, have internal components including line interface cards, backplanes, and control switch boards. The line interface card undertakes user interface conversion and user side flow normalization. The back board provides interconnection channels for the power bus, the control bus and the data bus of the control switch board and the line interface card. The control switch board, also called main control board, undertakes the convergence or forwarding of traffic between different line interface cards, and the forwarding of uplink interface.
Referring to fig. 1, the traffic forwarding path of a conventional small-capacity communication device is as follows:
(1) the first main control board controls the path of the flow data sent from the user side interface of the first line interface card to the network side interface of the first main control board
Firstly, a user side interface of a first line interface card 1 receives flow data; secondly, the first line interface card 1 sends the flow data to a first switching system 2 of a first main control board; then, the first switching system 2 of the first main control board sends the traffic data to a first uplink system of the first main control board (the first uplink system is integrated with the first switching system, which is not shown in fig. 1); finally, the first uplink system outputs the flow data from the network side interface of the first main control board 3;
(2) the first main control board controls the flow data to be sent from the user side interface of the first line interface card to the user side interface of the second line interface card
Firstly, a user side interface of a first line interface card 1 receives flow data; secondly, the first line interface card 1 sends the flow data to a first switching system 2 of a first main control board; then, the first switching system 2 of the first main control board transmits the traffic data to the second line interface card 4.
(3) When the first line interface card breaks down, the second line interface card sends the flow data from the user side interface of the second line interface card to the network side interface of the first main control board
Firstly, a user side interface of the second line interface card 4 receives flow data; secondly, the second line interface card 4 sends the flow data to a second switching system 5 of a second main control board; then, the second switching system 5 of the second main control board sends the traffic data to the first line interface card 1; thirdly, the first line interface card 1 sends the flow data to the first switching system 2 of the first main control board; then, the first switching system 2 of the first main control board sends the flow data to the first uplink system of the first main control board; finally, the first uplink system outputs the traffic data from the network-side interface of the first main control board 3.
From the above traffic forwarding path, the switching system of the main control board is a must-pass path for all traffic transmission.
For a small-capacity communication apparatus, since a line interface card of the small-capacity communication apparatus is generally compatible with a line interface card of a large-capacity communication apparatus, that is, the line interface card has versatility in communication apparatuses of different capacities, the size of the line interface card is fixed. And small capacity communication equipment generally only has 2U height, 8.9 centimetres promptly, and equipment internal dimension is limited, and like this, the space of reserving for controlling the switch board is also limited, and current control switch board not only includes main control board management module, still includes business conversion module, reports an emergency and asks for help or increased vigilance and clock module to and the module of joining in marriage, so, current control switch board must be through the mode of setting up of high integration, with above-mentioned four modules integration on the control switch board in limited space.
Therefore, higher requirements are put forward on the design of the control exchange board, and the high integration arrangement of the control exchange board is limited by space conditions, so that the coupling among modules is easy to occur, and the integration difficulty of the main control board is higher.
Disclosure of Invention
In order to solve the above technical problem, embodiments of the present invention are expected to provide a communication device, which can effectively reduce the integration difficulty of a main control board and simplify the design of the main control board.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The present embodiment provides a communication device, which may be a router, an ethernet switch, an Optical Line Terminal (OLT), a Digital Subscriber Line Access Multiplexer (DSLAM), and the like. Fig. 2 is a schematic diagram of a first structure of a communication device in an embodiment of the present invention, and referring to fig. 2, the device includes: a first line interface card 11, a second line interface card 12, a backplane 20, a first main control board 31 and a second main control board 32.
Here, the first line interface card 11 is connected to the backplane 20 and the first main control board 31 in sequence to form a first connection channel.
In this embodiment, the first line interface card 11 includes a first upper connection interface, which is a backplane side interface of the first line interface card. The first main control board 31 includes a first input interface, and the first upper connection interface is connected to the first input interface of the first main control board through a first connection channel. When the first line interface card 11 receives the traffic data with the first service requirement from the first user side interface 110 of the first line interface card, the first line interface card 11 may select the corresponding first connection channel according to the first service requirement, and first, send the traffic data with the first service requirement from the first user side interface to the first uplink interface; then, sending the flow data with the first service requirement to a first input interface of a first main control board through a corresponding first connecting channel; finally, after the first input interface of the first main control board 31 receives the traffic data with the first service requirement, the first main control board 31 outputs the traffic data with the first service requirement through the network side interface 310 of the first main control board, so that the first line interface card can select the corresponding first connection channel according to the first service requirement, and send the traffic data with the first service requirement from the user side to the network side, so as to implement the outgoing device forwarding of the traffic data.
It should be noted that the first service request may be an external traffic request of a user, such as a traffic request for uploading a file, a traffic request for downloading a file, and the like, at this time, the first line interface card sends traffic data from the user side to the network side, so as to provide the external traffic data for the user.
In this embodiment, the second line interface card 12 includes a second upper link interface, which is a backplane side interface of the second line interface card. The second upper connection interface of the second line interface card is connected with the first upper connection interface of the first line interface card through a second connection channel. When the first line interface card 11 receives the traffic data having the second service requirement from the first user side interface 110 of the first line interface card, the first line interface card 11 may further select a corresponding second connection channel according to the second service requirement, and first, send the traffic data having the second service requirement from the first user side interface to the first uplink interface; then, sending the flow data with the second service requirement to a second uplink interface of a second line interface card through a corresponding second connection channel; and finally, sending the flow data from the second upper connection interface of the second line interface card to the second user side interface of the second line interface card, so that the first line interface card can select a corresponding second connection channel according to a second service requirement, and sending the flow data with the second service requirement from the first line interface card to the second line interface card, so as to realize the forwarding of the flow data in the equipment. Therefore, the forwarding of the flow data between the first line interface card and the second line interface card of the invention is completed without the core processing of the main control board, and the transparent transmission of the flow data between different line cards can be realized directly through the second connecting channel between the first upper connection interface of the first line interface card and the second upper connection interface of the second line interface card, so that the functions of the main control board are simplified, and the integration level of the main control board is reduced.
It should be noted that the second service requirement may be a communication request between different users, such as a flow request for video communication or online game between users, at this time, the flow data is sent from the first line interface card to the second line interface card to provide flow data between different users.
Furthermore, when the first line interface card 11 receives the traffic data with the first service requirement from the first user side interface 110 of the first line interface card, and the second line interface card 12 receives the traffic data with the first service requirement from the second user side interface 120 of the second line interface card, the first line interface card 11 may also converge the traffic data with the first service requirement received by the second line interface card into the traffic data with the first service requirement received by the first line interface card through the second connection channel according to the first service requirement; next, the first line interface card 11 sends the aggregated traffic data with the first service requirement to the first main control board 31 through the first connection channel. After the first main control board 31 receives the converged traffic data with the first service requirement, the first main control board 31 outputs the converged traffic data with the first service requirement through the network side interface 310 of the first main control board, so that the first line interface card can converge the traffic data and send the converged traffic data to the first network side interface through the first connection channel under the condition that the first user side interface and the second user side interface both receive the traffic data with the first service requirement, thereby achieving the convergence of the traffic data between different line interface cards and outputting the converged traffic data to the device.
According to the above, after the line interface card acquires the traffic data, the line interface card of the present application can select the corresponding connection channel according to different service requirements, and send the traffic data to the main control board through the selected corresponding connection channel, at this time, the main control board only needs to output the received traffic data, and does not need to execute any service processing operation, that is, the main control board no longer has the function of a forwarding plane, so that the functions of the main control board are simplified, and the integration level of the main control board is reduced.
It should be noted that, in this embodiment, the first uplink interface of the first line interface card includes an uplink interface a1And an upper connection interface A2The second upper connection interface of the second line interface card comprises an upper connection interface B1And an upper connection interface B2。
In practical applications, the connection relationship between the first line interface card 11 and the first main control board 31 and the connection relationship between the first line interface card 11 and the second line interface card 12 may be: the upper connection interface a1 of the first line interface card is connected with the first input interface of the first main control board through a first connection channel, and the upper connection interface a2 of the first line interface card is connected with the upper connection interface B2 of the second line interface card through a second connection channel. Meanwhile, the connection relationship between the second line interface card 12 and the second main control board 32 may be: the upper connection interface B1 of the second line interface card is connected with the second input interface of the second main control board through a third connection channel, which is similar to the first connection channel in structure and function.
As can be seen from the above, the first line interface card or the second line interface card in this embodiment can undertake aggregation or forwarding of traffic data between different line interface cards, and uplink forwarding.
However, in the conventional communication device, the line interface card can only be used to undertake user interface conversion and user side traffic normalization, and the aggregation or forwarding and uplink forwarding of traffic data between different line interface cards are implemented by a service conversion module, i.e. a switching system, and an uplink module, i.e. an uplink system, of the main control board. It can be seen that, in the conventional small-capacity communication device, the service conversion module and the uplink module are indispensable modules for the main control board, and since the space reserved for the main control board in the conventional small-capacity communication device is limited, a designer must highly integrate the modules on the main control board together, and the problem of high integration difficulty of the main control board is caused by the adoption of the highly integrated mode, which is easily caused by the coupling between the modules.
In this embodiment, in order to solve the problem of high integration difficulty of the main control board, a service conversion module and an uplink module on the main control board are omitted, functions of the modules are put on the line interface card, the line interface card selects a corresponding connection channel according to received traffic data with different service requirements, and sends the traffic data to the corresponding main control board through the selected corresponding connection channel, and then the main control board outputs the received traffic data to the device. In addition, in the forwarding process of the flow data, the invention can take the backboard side interface of the line interface card as the uplink interface to be matched with different service requirements to realize uplink forwarding, thereby effectively reducing the integration difficulty of the main control board.
Further, in the present embodiment, as for the arrangement of the second connection passage, the following three arrangement manners may exist and are not limited.
First, referring to fig. 3, a second connecting channel passes through the back plate, and the second connecting channel is: an Ethernet interface channel or a serial interface channel, and the second connection channel is a connection line. At this time, one end of the second connection channel is connected with the uplink interface a2 of the first line interface card, and the other end of the second connection channel is connected with the uplink interface B2 of the second line interface card, so that after the first line interface card receives the traffic data with the second service requirement from the first user side interface, firstly, the corresponding second connection channel is selected according to the second service requirement; the traffic data having the second traffic requirement is then sent to the second line interface card via the second connection channel. Therefore, the first line interface card and the second line interface card can directly transmit the flow data between the line interface cards through the second connecting channel. However, in the conventional small-capacity device, the first line interface card must first send the traffic data to the first main control board, and then the main control switching system of the first main control board selects a forwarding path of the traffic data, and then the traffic data can be sent to the second line interface card.
However, in practical applications, as can be seen from fig. 3, if the first line interface card 11 or the second line interface card 12 fails, that is, the first line interface card 11 or the second line interface card 12 is not in an online state, the uplink port of the failed line interface card cannot implement uplink forwarding of data traffic, so that only one line interface card working online can send traffic data from the user side to the network side, and only one network side interface can receive the traffic data.
Further, in this embodiment, the second connection channel shown in fig. 3 is improved, and a switch module is arranged on the second connection channel, and the switch module is configured to connect the first uplink interface and the second uplink interface, and transmit the traffic data having the second service requirement from the first uplink interface to the second uplink interface, or transmit the traffic data having the second service requirement from the second uplink interface to the first uplink interface. The switch module may also be configured to conduct a user side interface of another line interface card and a network side interface of the main control board corresponding to the failed line interface card when any line interface card in the device fails, so as to ensure that traffic data on the network side is still not reduced at this time.
It should be noted that, the switch module in the present invention may physically integrate a plurality of single-pole double-position switches and/or field programmable gate arrays to implement the corresponding switching function, and the embodiment of the present invention is not particularly limited.
Secondly, referring to fig. 4A and 4B, the switch module is disposed on the backplane, the first uplink interface is connected to the first port of the switch module, the second uplink interface is connected to the second port of the switch module, and a second connection channel is formed between the first uplink interface and the second uplink interface. The switch module further comprises a third port, and the third port is connected with the first input interface of the first main control board. Specifically, referring to fig. 4A, when two line interface cards in the device are both in a normal operating state, after the first line interface card 11 receives traffic data having a first service requirement from the first user side interface 110 of the first line interface card, the first line interface card 11 may select a corresponding first connection channel according to the first service requirement, and first send the traffic data having the first service requirement from the first user side interface to the first uplink interface; then, the switch module conducts the first connecting channel and sends the flow data with the first service requirement to a first input interface of the first main control board; finally, after the first main control board 31 receives the traffic data with the first service requirement, the first main control board 31 outputs the traffic data with the first service requirement through the network side interface 310 of the first main control board. Meanwhile, after the second line interface card 12 receives the traffic data with the first service requirement from the second user side interface 120 of the second line interface card, the second line interface card 12 may select a corresponding third connection channel according to the first service requirement, and first, the traffic data with the first service requirement is sent from the second user side interface to the second uplink interface; then, the switch module conducts the third connection channel and sends the flow data with the first service requirement to a second input interface of the second main control board; then, after the second main control board 32 receives the traffic data with the first service requirement, the second main control board 32 outputs the traffic data with the first service requirement through the second network side interface 320 of the second main control board. In this way, when the first line interface card 11 and the second line interface card 12 are both in a normal operating state, both the first network-side interface 310 and the second network-side interface 320 can receive traffic data from the user side.
When any line interface card in the device fails, as shown in fig. 4B, for example, the first line interface card 11 fails, at this time, the second line interface card 12 operates normally, and after the second line interface card 12 receives the traffic data having the third service requirement from the second user-side interface 120 of the second line interface card, the traffic data having the third service requirement is sent to the second uplink interface; sending the traffic data having the third service requirement to a second port of the switch module; the switch module conducts the second port of the switch module and the third port of the switch module to form a third channel; sending the flow data with the third service requirement to a first input interface of the first main control board through a third channel; after receiving the traffic data with the third service requirement, the first main control board sends the traffic data with the third service requirement from the first input interface to the first network side interface, and outputs the traffic data through the first network side interface. In this way, when the first line interface card fails, one part of the traffic data having the third service requirement is sent to the first network side interface, and the other part of the traffic data having the third service requirement is sent to the second network side interface, so that both network side interfaces of the device can receive the traffic data from the user side, and the purpose of uplink protection is achieved.
Thirdly, referring to fig. 5A and 5B, the switch module includes a first sub-switch module and a second sub-switch module, the first sub-switch module is disposed on the first main control board, and the second sub-switch module is disposed on the second main control board. The upper connection interface A2 is connected with the first port of the first sub-switch module, and the second port C of the first sub-switch module1And the first port C of the second sub-switch module2And the second port of the second sub-switch module is connected with the upper link interface B2, and a second connection channel is formed between the upper link interface a2 and the upper link interface B2.
At this time, the first and second sub-switch modules are the switch 311 and the switch 321 in fig. 5A, respectively. Here, referring to fig. 6A and 6B, the switch 311 may be replaced with a simple switch 311, i.e., a lite SW, and the switch 321 may be replaced with a simple switch 321, i.e., a lite SW. The first sub-switch module further comprises a third port, and the third port is connected with the first network side interface. In practical applications, after the first line interface card 11 receives the traffic data with the second service requirement from the first user side interface 110 of the first line interface card, the first line interface card 11 may select a corresponding second connection channel according to the second service requirement, and at this time, the switch module turns on the second connection channel, specifically, referring to fig. 5A, the switch 311 turns on the first port of the first sub-switch module and the second port C of the first sub-switch module1Sending the flow data with the second service requirement to the second port C of the first sub-switch module1And the switch 321 turns on the first port C of the second sub-switch module at the same time2And a second port of a second sub-switch module, which transmits the flow data with a second service requirement to the second port of the second sub-switch module; then, the flow data with the second service requirement is sent to the second uplink interface B2In this way, the traffic data with the second service requirement received by the first user-side interface 110 of the first line interface card is sent to the second user-side interface 120 of the second line interface card, so as to implement transparent transmission of the traffic data between different line interface cards.
In addition, after the first line interface card 11 receives the traffic data with the first service requirement from the first user side interface 110 of the first line interface card, the first line interface card 11 may select the corresponding first connection channel according to the first service requirement, and first, send the traffic data with the first service requirement from the first user side interface to the first uplink interface; then, sending the flow data with the first service requirement to a first input interface of a first main control board; finally, after the first main control board receives the traffic data with the first service requirement, the first main control board outputs the traffic data with the first service requirement through a network side interface of the first main control board, so that the traffic data is sent from the user side to the network side.
When any line interface card in the device fails, as shown in fig. 5B, for example, the first line interface card 11 fails, at this time, the second line interface card 12 operates normally, and after the second line interface card 12 receives the traffic data having the third service requirement from the second user-side interface 120 of the second line interface card, the second line interface card sends the traffic data having the third service requirement to the second uplink interface; sending the traffic data with the third service requirement to a second port of the second sub-switch module; at this time, the second sub-switch module conducts the first port of the second sub-switch module and the second port of the second sub-switch module, and sends the traffic data with the third service requirement to the first port of the second sub-switch module, and meanwhile, the first sub-switch module conducts the second port of the first sub-switch module and the third port of the first sub-switch module, and sends the traffic data with the third service requirement to the third port of the first sub-switch module; and sending the traffic data with the third service requirement to the first network-side interface, so that the second line interface card 12 can send one part of the traffic data to the first network-side interface 310 and send the other part of the traffic data to the second network-side interface 320, so as to ensure that both network-side interfaces of the device can receive the traffic data from the user side, and achieve the purpose of uplink protection.
In this embodiment, the master/standby conditions of the first master control board and the second master control board may also be switched, and when the device is factory-set, the first master control board may be defaulted as the master control board, where the master control board is configured to receive state information reported by a first line interface card associated with the master control board, and the state information includes: the online status of the first line interface card, i.e. the first line interface card is in working status or the first line interface card is out of order. Further, when the first main control board is the main control board and the first main control board acquires that the first line interface card has a fault, the first main control board switches the main and standby conditions of the first main control board and the second main control board, after the switching, the second main control board is the main control board, and the first main control board is the standby control board. When the first line interface card is repaired and is recovered to a working state, the equipment recovers the first main control board as the main control board.
According to the invention, the service conversion module and the uplink module on the main control board are omitted, the functions of the modules are put on the line interface cards, and then the convergence or forwarding of the flow data among different line interface cards and the uplink forwarding are realized through the line interface cards, so that the integration difficulty of the main control board is effectively reduced. In this embodiment, the main control board only needs to support the control plane management function, may not support the function of the forwarding plane, and adopts a coreless switching or simple switching design, thereby reducing the cost and power consumption of the device.
