SDN (Software Defined Network) based residence community network control system

Abstract

The invention discloses an SDN (Software Defined Network) based residence community network control system. The SDN based residence community network control system specifically comprises a home network service terminal which is used for replacing an existing router in the home to receive an instruction of an SDN controller; a community switch which receives the instruction of the SDN controller and directly provides QoS guarantee for different home network service terminals; a virtualization server which is used for providing a virtual PC desktop service for domestic users in the community, receiving the instruction of the SND controller and providing the QoS guarantee for different virtual desktop connections; the SDN controller which is the control center of the whole community network, dynamically sends down a flow table to the home network service terminal, the community switch and the virtualization server based on the current condition of the community network, distributes a bandwidth source for each network connection of the users from top to bottom and provides the QoS guarantee. The SDN based residence community network control system realizes the advantage of providing an exquisite QoS management mechanism for the users.

Description

technical field [0001] The invention relates to the field of computer network networking and control, in particular to an SDN-based residential area network control system. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a new innovative network architecture proposed by researchers at Stanford University in the United States, which can separate the control plane of network equipment from the data plane, thereby realizing flexible control of network traffic. The innovation of core network and application provides a good platform. In recent years, the idea of ​​SDN has been applied to various application scenarios to help people control the network more flexibly and conveniently. [0003] At present, most of the network deployment schemes in residential quarters are traditional mechanisms. Telecom operators provide users with network lines with a certain bandwidth. Business and access scenarios are dynamically adapted. During low ac...

[0003] At present, most of the network deployment schemes in residential quarters are traditional mechanisms. Telecom operators provide users with network lines with a certain bandwidth. Dynamic adaptation to business and access scenarios

During the low access peak, the bandwidth of different users in the community cannot be shared. During the high access peak, different users in the community have to compete for the provided Ethernet egress, which makes the utilization efficiency of bandwidth resources relatively low.

At the same time, the traditional QoS service is port-based, or service-based, and the same service data packets of different users or user groups are treated equally, which cannot provide users with more refined QoS
