System and method for achieving multi-service priorities

Abstract

The invention provides a system and method for achieving multi-service priorities and relates to the technical field of computer communication. The system comprises an SDN controller, at least one VxLAN gateway and at least two VLAN switches. The SDN controller comprises a northbound interface processing module, an IP processing module, an ARP processing module, a topology management module, an interflow domain management module and an SDN OpenFlow interface module. Each VxLAN gateway comprises a configuration management module, a VxLAN OpenFlow interface module, a flow table management module, a tunnel encapsulation processing module, a tunnel decapsulation processing module, an application layer service recognition processing module and a VxLAN receiving and transmitting package module. Each VLAN switch comprises a VLAN receiving and transmitting package module and a VLANID module. According to the system and the method, the performance of hardware is not required, a special communication processor does not need to be used, and the equipment cost is lowered.

Description

technical field [0001] The invention relates to the technical field of computer communication, specifically a system and method for realizing multi-service priority. Background technique [0002] SDN (software defined networking, software defined network) is a hot topic in the current network communication field, and it is strongly sought after by major network equipment manufacturers because of its isolated switch control and forwarding functions. In recent years, with the rapid development of network technology and applications and the diversification of network access forms, the network has become more and more complex, and at the same time, user services have become more and more complex. [0003] According to the statistics of my country's Internet business traffic, P2P services currently occupy a large amount of broadband in various services. The emergence of a large number of P2P services on the network causes extreme network congestion and brings losses to operators...

AI Technical Summary

Problems solved by technology

P2P flow control processing, QoS processing and other tasks are all processed by dedicated hardware. Although the above tasks are processed by additional hardware, although the business processing performance of network equipment is not affected, these dedicated communication processors generally have a relatively high cost and are not suitable for use. on low-end devices
