Method and system for measuring home gateway cpu speed

Abstract

The invention discloses a home gateway CPU speed measurement method and system, and relates to the field of gateway speed measurement. The method includes establishing a TCP connection with a speed measurement server; determining quintuple information of a speed measurement data packet sent by the speed measurement server, and configuring the speed measurement data packet , receiving the speed measurement data packet to the network card; the network card enables LRO to receive N speed measurement data packets, encapsulates it into a transmission data packet, and sends it to the network card protocol stack; the network card protocol stack unpacks the transmission data packet into N speed measurement data packets The data packet, through the ACK response of the network card protocol stack, gets N response data packets, and sends them to the network card, and accumulates the received data length L of the speed measurement data packet; the network card enables LSO to return the response data packet to the speed measurement server; the interval time T, two acquisitions The received data length L is used to calculate the data transmission rate of the network card according to the change of L. The invention can reduce the impact of other speed measurement environments such as uplink and downlink messages and network protocols on the gateway speed test.

Description

technical field [0001] The invention relates to the field of gateway speed measurement, in particular to a CPU speed measurement method and system for a home gateway. Background technique [0002] With the development of big data and the popularization and application of smart terminals, as the core of home network networking - home gateway, it has access to various services including set-top boxes, routers, and telephones. [0003] However, based on the rapid development of Internet big data and large throughput; and considering the application of high-definition video and data transmission, operators also need to know the bandwidth size and bandwidth stability of home network users. carry out testing. [0004] At present, operators have two verification tests for the broadband rate. One is the forwarding rate of the gateway: the forwarding capability of the uplink and downlink data packets to the downlink set-top box, downlink PC or downlink wireless terminal through the ...

Problems solved by technology

[0005] However, due to the diversity of gateway solutions and the differences in chip processing capabilities, the results of the test rate are closely related to the chip frequency and the data path optimization of the protocol stack. Further, the broadband rate test passes the PON side and the protocol stack itself. The uplink and downlink messages of other non-download servers have a greater impact on the test results, resulting in rate statistics that do not reach the theoretical processing speed of the chip and rate fluctuations. In view of the above, an optimization system that does not need to consider the impact of the speed measurement environment on the message download rate is needed method

[0006] Furthermore, when the performance of the gateway processor is insufficient, the data packets go through the LINUX protocol stack to load HOOK, which will cause the problem that the speed measurement cannot meet the standard
