Embodiment

With reference to the accompanying drawings and examples to a kind of business line card provided by the utility model and based on PCIE bus backplanes Communication system be described in more detail.

As shown in Fig. 2 the utility model embodiment provides a kind of business line card 001, applied to based on PCIE bus backplanes Communication system in, the business line card 001 include PCIE bridge pieces 011, processor 012, PCIE buses；PCIE bridge pieces 011 pass through PCIE buses are connected with processor 012；Business line card also includes network controller 013 and network-bus；Wherein：

Network controller 013, for expanding network-bus connectivity port from PCIE bus connection ports；

PCIE bridge pieces 011 are connected by PCIE buses with network controller 013；

Network controller 013 is connected by network-bus with processor 012.

In scheme of the present utility model, on business line card, by way of the extended network controller under PCIE bridge pieces Function of network exchange is expanded, the processor being docked on business line card, the network interconnection of processor and power board is realized, reaches Realize the purpose of network and PCIE double crossing over buses；Because function of network exchange is to be expanded from PCIE buses by network controller Exhibition, all network packets are transmitted by the physical link of PCIE buses, so need not reuse big end in The network exchanging chip of mouth, without changing original PCIE bus backplanes, can simplify structure, cost is greatly reduced.

When it is implemented, can have the processor of multiple processing business in business line card, the quantity based on processor is not Together, accordingly, the structure of business line card has a variety of, and two of which structure is set forth below.

In a kind of possible embodiment, it is preferred that as shown in figure 3, the quantity of processor 012 is N number of, network controller 013 quantity is N number of；Wherein, N value is positive integer；

PCIE bridge pieces 011 are connected with N number of processor 012 respectively by N bar PCIE buses；

PCIE bridge pieces 011 are connected with N number of network controller 013 respectively by N bar PCIE buses；

N number of network controller 013 is connected with N number of processor 012 respectively by N bars network-bus.

In alternatively possible embodiment, it is preferred that as shown in figure 4, the quantity of processor 012 is N number of, network controls The quantity of device 013 is 1；N value is the positive integer more than 1；

Above business line card 001 also includes 1 network bridge piece 014；

PCIE bridge pieces 011 are connected by 1 PCIE bus with 1 network controller 013；

1 network controller 013 is connected with 1 network bridge piece 014；

1 network bridge piece 014 is connected with N number of processor 012 respectively by N bars network-bus.

Holistic cost in view of reducing network controller, if during the negligible amounts of processor, can use more than the A kind of structure, the corresponding network controller of each processor；If the quantity of processor is more, second of knot can be used Structure, only utilize a network controller, multiple network connection ports are then expanded by network bridge piece, respectively with N number of processing Device connects.

Based on same design, the utility model embodiment also provides a kind of communication system based on PCIE bus backplanes, As shown in figure 5, the business line card of the backboard 003 and multiple such as any of the above embodiments including power board 002, based on PCIE buses 001；Power board 002 and each business line card 001 are connected with the PCIE buses on backboard 003 respectively.

In the scheme of the utility model embodiment, on business line card, pass through the extended network controller under PCIE bridge pieces Mode expand function of network exchange, the processor being docked on business line card, realize that the network of processor and power board is mutual Even, the purpose for realizing network and PCIE double crossing over buses is reached；Because function of network exchange is to pass through network from PCIE buses Controller is expanded, and all network packets are transmitted by the physical link of PCIE buses, so without again in Using the network exchanging chip of large port, without changing original PCIE bus backplanes, structure can be simplified, be greatly reduced into This.

Wherein, power board 002 includes the CPU management 022 that PCIE exchange chips 021 are connected with PCIE exchange chips；Exchange The PCIE exchange chips 021 of plate are connected with the PCIE buses on backboard.In power board, due to only needing to manage PCIE exchange cores Piece, without managing network exchanging chip, reduce exploitation and the complexity safeguarded.

It should be noted that the structure of the communication system of the present utility model based on PCIE bus backplanes can be, but not limited to Applied to video technique field, if applied in video field, communication system can be video matrix or splicing controller.

It should be noted that exchange process can be initiated by business line card side or power board side, it is necessary to transmission There are the sending port address and destination interface address of transmission in packet, thus can be true by topological network and port address Surely transmitted by network-bus or by PCIE bus transfers.

Below by taking the video matrix equipment with single PCIE buses as an example, video matrix equipment includes power board 002, base Backboard 003 and multiple business line cards 001 in PCIE buses.

Wherein, power board 002 includes CPU management 022 and PCIE exchange chips 021.Core is exchanged by CPU management management PCIE Piece, the data exchange between each business line card is completed by PCIE buses.Power board 002 is carried on backboard and arrives each business The PCIE bus physical links of card 001, in star-like topology.

The function of network exchange is realized, is only realized by business line card.

In the present embodiment, business line card 001 includes 1 network bridge piece of network controller 013,1 of PCIE bridge pieces 011,1 With N number of processor.PCIE bridge pieces are connected by PCIE buses with 1 network controller, expand network-bus, pass through 1 net Network bridge piece connects N number of processor on business line card respectively.Assuming that there are 2 processors to need to dock network on business line card, such as Shown in Fig. 6, at this moment can hangs 1 network controller 013 in the down going port of PCIE bridge pieces 011, and this network controller 013 is again The network connection realized in network bridge piece 014 with 2 processors 012 is connected to, now, due to the negligible amounts of processor, even Network bridge piece 014 can be saved, 2 network controllers 013 are hung in the down going port of PCIE bridge pieces 011, directly by network controller 013 docks with processor 012, as shown in Figure 7.Thus, it is possible to realize CPU management on power board with it is each on business line card 1 Network exchange between processor.Similarly, the net between the processor on the CPU management and business line card 2 on power board is realized Network exchanges.Middle bridge is used as by CPU management, realizes the network exchange between business line card 1 and business line card 2, and realize Network exchange between all business line cards.

In the present embodiment, the network exchanging chip scheme that large port is equipped with tradition realizes that the network between business line card is handed over The mode of changing is compared, this network exchange bus expanded by PCIE, and realization is very flexible, completely can be according to business line card Demand customized network bandwidth, the PCIE2.0/3.0 of main flow port bandwidth is considerably beyond current main-stream gigabit networking bandwidth at present, Influence very little after true extension network-bus to PCIE data bandwidths.And tradition is equipped with large port network exchanging chip to each The bandwidth of line slot has just just been secured in design, and so some applications for needing to use big broadband network can be made on the contrary Into limitation.

Obviously, those skilled in the art can carry out various changes and modification without departing from this practicality to the utility model New spirit and scope.So, if these modifications and variations of the present utility model belong to the utility model claims and Within the scope of its equivalent technologies, then the utility model is also intended to comprising including these changes and modification.
