The invention discloses a method and device for achieving high-speed broadband based on multiple processing logic lines. Messages enter a chip from physical layer ports of the chip and undergo analysis of processing engines and forwarding of forwarding managing modules in the entering direction of the processing logic lines, undergo editing of the processing engines in the exiting direction of the processing logic lines and are outputted from the chip physical layer ports. A connection channel is arranged between the forwarding managing modules of every two processing logic lines to process messages by spanning the processing logic lines. According to the method and device for achieving high-speed broadband based on multiple processing logic lines, messages can be processed by the processing logic lines at the same time; meanwhile, messages can be processed by spanning the processing logic lines, the speed in processing the messages by the chip is greatly improved, the gradually higher requirement for band width is met, the development cost of the chip is low, the practicability is high and popularization and use of the method and device for achieving high-speed broadband based on the processing logic lines are convenient to perform.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a method and a device for realizing high-speed bandwidth by adding processing logic lines inside a chip. Background technique [0002] With the rapid development of networks and more and more applications of packet processing chips, the requirements for packet processing chips are also getting higher and higher. Especially in recent years, the hot development of cloud computing technology and data center technology usually requires the bandwidth of Ethernet switches to reach 100 Gbps or even 1,000 Gbps, which requires the core component of Ethernet switches, a packet processing switching chip, to provide higher bandwidth. [0003] The current packet processing and switching chip adopts ASIC technology, integrates complex processing and forwarding logic inside the chip as much as possible, and processes data through the chip hardware, thereby greatly improving the pr...
