A programmable stream processing device and method based on instruction set

Abstract

The invention discloses a programmable stream processing device and method based on an instruction set, belonging to the technical field of network communication. The device includes a CPU configuration module, a parser module, a TCAM matching module, a HASH matching module, a BV matching module and an RBVE matching module. The search fields of flow tables at all levels in the device are dynamically programmable, and action processing instructions are designed for different packet processor types through customized instruction sets and considering their functional requirements. Different matching search algorithms are used for different matching fields, and the actions performed after the search are all programmable. Each level of flow table has an enabling terminal, and it can be decided whether to activate the flow table of this level according to the actual application situation, which fully reflects the characteristics of variable flow table levels, variable capacity, and protocol independence.

Description

technical field [0001] The invention belongs to the technical field of network communication, in particular to a programmable flow processing device and method based on an instruction set. Background technique [0002] With the continuous development of technology, the Internet has been fully integrated into people's daily work and life. The rapid development of the Internet and wireless communication technology has led to the advent of an information society, where almost everything can be connected to each other and can be connected to the network from almost anywhere. However, while these network services provide convenience for people, they also pose serious challenges to the traditional Internet architecture. The continuous increase in the demand for network bandwidth and the diversified demands of various emerging network services have put forward higher requirements for the function and performance of the network, resulting in the contradiction between the network sc...
