High-speed isolated network method and terminal based on pcie

Abstract

The invention discloses a high-speed isolation network method and terminal based on a PCIE. The high-speed isolation network terminal based on the PCIE comprises a plurality of processors, wherein a unique IP address is allocated to each processor; a PCIE data switch chip which is connected with each processor through a PCIE bus, thereby enabling any processor to be in communication connection with one or more processors; a virtual network card which is used for intercepting data transmitted to the Ethernet in a physical layer when one processor sends the data, transmitting the data to corresponding processors through the PCIE bus according to different IP addresses, analyzing data and converting the data into corresponding IP addresses when the corresponding processors receive the data and sending the corresponding IP addresses to a network protocol stack, thereby realizing data transmitting and receiving of different processors. According to the method and the terminal, network resources do not need to be planned, the relatively high closing performance is achieved, a relatively high transmission rate is realized, the relatively low transmission delay is realized, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of multimedia communication, in particular to a PCIE-based high-speed isolation network method and a terminal. Background technique [0002] As people's demand for high-definition video is getting higher and higher, there are also higher requirements for the encoding and decoding capabilities of video conferencing terminals. The traditional single video conferencing terminal uses a single processor for multi-channel encoding and decoding. Instead, the same video conferencing terminal is required, with multiple processors working together to share the pressure of encoding and decoding, thereby providing greater image capabilities and providing users with a better effect experience. [0003] At present, Ethernet is mostly used to transmit data when multiple processors of the same video conferencing terminal work together. Each processor must allocate network resources, and the network resources in the same ne...

AI Technical Summary

Problems solved by technology

[0003] At present, Ethernet is mostly used to transmit data when multiple processors of the same video conferencing terminal work together. Each processor must allocate network resources, and the network resources in the same network segment are limited, requiring customers to re-plan the network resource division vlan, etc., which additionally increases the customer's overhead; the Ethernet transmission method has a larger scope, There are multiple terminals in the local area network, and the multiple processors of each terminal can be connected to the network, so it is easy to interfere with each other and is not closed; Ethernet can only support Gigabit at a maximum rate of 1000Mbsp at present, while The video conferencing system has very high real-time requirements, and the above-mentioned transmission rate cannot meet the transmission requirements.
