Method for caching mixed service flow and method and device for storing and forwarding mixed service flow

Abstract

The invention discloses a method for caching a mixed service flow and a method and a device for storing and forwarding the mixed service flow. The method for caching the mixed service flow comprises the following steps: A1, configuring at least one port cache region for each input port receiving the input of the mixed service flow respectively, and configuring at least one type cache region for each service type of the mixed service flow respectively; A2, storing control information of each data packet into the port cache region of a corresponding port respectively according to the source of the port of each data packet; and A3, identifying the service type of each data packet by using the control information of the data packet, and storing the control information of each data packet intothe type cache region corresponding to the service type respectively according to the service type of each data packet. The method for caching the mixed service flow allows the data packet of each type from each port to share an independent processing procedure, thereby not only improving the overall performance index, but also being convenient to control the ratio of the overall bandwidth occupied by the data packets with different types, and simultaneously having good expandability.

Description

technical field [0001] The invention relates to the field of Ethernet data service processing, in particular to a buffering and processing method, storage and forwarding method and device for mixed service flows. Background technique [0002] It is a relatively complicated and cumbersome work to process the data of multi-port input mixed service flow. At present, in the process of processing the mixed business process with multi-port input, the same processing method as the single business flow is still adopted, that is, the input data flow is applied for and stored in the data cache according to the order of input, and the data packets entering the queue are completed. It is assigned to the corresponding queue and waits for the output scheduling application. Each queue has different output attributes, and according to these attributes, scheduling is carried out according to a certain scheduling strategy. Therefore, the data packet is read out from the cache, and the data ...

Problems solved by technology

However, with the rapid development of data services, such processing has become somewhat stretched, neither can meet the performance requirements of mixed service processing, nor is it conducive to the processing and monitoring of a certain service

At the same time, due to the large number of business types of the mixed service flow, the number of service input ports is also increasing. In the prior art, the method of data caching only according to the input order increases the complexity of testing the mixed service flow data packets. The test is more difficult
