SDN-based network control system for residential quarters

Abstract

Disclosed is an SDN-based residential cell network control system, specifically comprising: a home network service terminal for substituting an existing router in a home, receiving an instruction of an SDN controller and providing a QoS guarantee for different terminals; a cell switch for connecting to the home network service terminal, receiving the instruction of the SDN controller and providing a QoS guarantee for different home network service terminals; a virtualized server for providing a virtualized desktop service to an intra-cell home user, receiving the instruction of the SDN controller and providing a QoS guarantee for different virtualized desktop connections; and the SDN controller, being a control centre of the whole cell network and used for dynamically issuing a flow table to the home network service terminal, the cell switch and the virtualized server according to a current condition of the cell network, allocating network bandwidth resources to each network connection of the user from top to bottom, and providing a QoS guarantee.

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 network innovation 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 , providing a good platform for core network and application innovation. 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 acc...

Problems solved by technology

[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
