A data switch processing board and its corresponding switch processing system

Abstract

The invention discloses a data exchange processing board and a corresponding exchange processing system thereof, which pertains to the technical field of communication. The exchange processing board comprises at least one FPGA device and network search engines which are same with the FPGA devices in number and provides rich functions of filtering and processing based on contents; each FPGA is connected with a back board by an interface of a serialized / deserialized connector; a plurality of FPGA devices can realize the full mesh of star topology. The exchange processing system comprises a plurality of data exchange processing boards, which realize multi-level structural network. The data exchange processing board and the exchange processing system thereof can support the dynamic extension of FPGA of different quantities and even can cascade limitlessly within a range allowed by the interface, which break through the defects of the traditional back board exchanging system in data aggregation and processing and solve the limitation of current back board exchanging technology in respect of band width and expansibility.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a high-density data exchange processing board and a corresponding exchange processing system thereof. The exchange processing board is suitable for constructing data exchange processing boards of Internet T-bit-level core routers and switches. Background technique [0002] Large-scale communication systems, such as T-bit core routers and switches, usually consist of the following main components: Line Card, Switch Card, Backplane, etc., such as figure 1 (Schematic diagram of the structure of the core routing and switching system). The functions of each component are as follows: the line card is responsible for data access processing, and is also responsible for the queue and flow management of the data output to the backplane; the switch processing board is responsible for the data exchange processing between the line cards; The bridge of the processing board, which connects...

Problems solved by technology

Although this solution can realize data interaction between TMs, it cannot realize data interaction in Fabric, and it is not convenient for centralized processing and scheduling of data.

If it is necessary to realize the connection and data exchange between Switch Fabric chips, each Fabric chip needs to sacrifice half of the bandwidth. Obviously, this kind of application is less flexible than parallel use, and sacrifices the switching bandwidth. In practical applications is worth the candle
