Port statistical parameter announcement method and equipment

Abstract

The invention provides a port statistical parameter notification method and device. A switch chip on a communication device applying the method identifies a plurality of received parameter remote query messages from a server where a remote processor is located; the exchange chip reads the corresponding statistical parameters according to the register addresses carried by each parameter remote query parameter; the switching chip generates a parameter remote response message for each read statistical parameter; and the switch chip sends each generated parameter remote response message to the server, so that the processor of the server processes all the collected required statistical parameters of the controlled port into structured serialized port statistical data and sends the structured serialized port statistical data to the controller, thereby avoiding occupying a processor processing resource of the communication equipment to read a port statistical parameter register.

Description

technical field [0001] The invention relates to communication technology, in particular to a port statistical parameter notification method and equipment. Background technique [0002] In visualization applications, network devices using in-band network telemetry (In-band Network Telemetry) can use data structuring technology (for example, protobuf technology) to serialize (serialize) the statistical parameters of the local controlled port storing, and then sending the serialized port statistical data to a software-defined network (Software Define Network, SDN) controller through a UDP message. [0003] In existing solutions, the processor of the network device reads the registers on the switch chip one by one to obtain each required statistical parameter, such as the total number of packets received / sent by the port, the total number of bytes received / sent by the port, The total number of unicast / multicast / broadcast packets sent by the port, the total number of packets sen...

Problems solved by technology

[0004] However, the processor of a network device often needs to process a large number of protocol packets and some data packets that need to be processed by software. If the controller reads the registers of each port statistics parameter one by one, it will greatly occupy the processor processing resources of the network device and reduce the processing ability of the device processor for protocol packets.
