Content-customizable field-based stream matching method

Abstract

The invention discloses a content-customizable field-based stream matching method. The method includes the following steps that: a network user autonomously customizes a data stream format for streammatching; the customized data stream format is reported to a control plane; matching fields in a first stream table in the customized data stream format are matched with corresponding fields in data streams to be matched according to the matching fields; data stream types are distinguished according to protocol types in MAC headers, and the distinguished data streams are forwarded to a corresponding stream table group for further matching; if the matching of the data streams to be matched is successful, a switching device forwards the successfully-matched data streams, makes the data streams skip to another stream table, reports the data streams to the control plane or perform deep analysis operation on the data streams; and if the matching of the data streams to be matched fails, the datastreams of which the matching fails are reported or discarded. The above method has good flexibility and scalability while being compatible with an existing network, can greatly broaden the design thinking of network researchers, and is of great significance for the future research of the Internet.

Description

technical field [0001] The invention relates to the technical field of data flow matching, in particular to a flow matching method for a user-definable content field. Background technique [0002] At present, the data flow matching mechanism is a key point in the field of Internet research. Flow matching needs to determine the destination address of the data flow, the exit and the next hop address of the data flow based on the information contained in the data flow. At the beginning of the existing Internet design, it did not take into account the rapid development of the Internet, especially the explosive growth of network content. Technology is changing with each passing day, and network transmission has become a bottleneck restricting network development. Today, the development of the Internet is facing many problems such as poor scalability, poor mobility, poor security, and low resource utilization. Network transmission cannot meet the transmission needs of massive, ef...
