Problems solved by technology

However, since the current OpenFlow protocol does not support QoS, directly deploying SIP-based IP multimedia applications on the OpenFlow network still cannot guarantee QoS

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, the QoS implementation method based on OpenFlow needs to improve the SIP switch and the OpenFlow switch in the enterprise-level SIP switch of the present invention; IP multimedia application configures QoS level and parameters. The QoS setting interface is implemented based on a WEB browser. It can interact with the core of the SIP switch through the internal communication mechanism (the current version does not need to interact with the core of the SIP switch), and centralized control with the OpenFlow switch. The QoS policy is transmitted between switches through the OpenFlow protocol; the OpenFlow switch part needs to add QoS rule base, data flow aggregator, traffic controller, exchange queue manager and other modules to the centralized control module. Among them, the QoS rule library is used to r...

Abstract

The invention relates to an implementation method of QoS (Quality of Service) in enterprise-level multimedia communication, in particular to a QoS (Quality of Service) implementation method of enterprise-level multimedia communication based on an OpenFlow network. According to the method, a plurality of service levels of enterprise-level multimedia applications based on SIP (Session Initiation Protocol) exchange are defined, and group control and management are performed on data streams of different service levels through a control plane separated from a network data network, so that the service quality on the aspects of network bandwidth, delay and the like is ensured for applications such as IP-based voice, videos and multimedia conferences.

Description

technical field [0001] The invention relates to a method for realizing QoS in enterprise-level multimedia communication, in particular to a method for realizing QoS in enterprise-level multimedia communication based on an OpenFlow network. This method defines a variety of service levels of enterprise-level multimedia applications based on SIP exchange, and controls and manages data streams of different service levels in groups through the control plane separated from the network data plane, providing voice, video, and multimedia conferences based on IP. Such applications provide guarantees of service quality such as network bandwidth and delay. Background technique [0002] In recent years, with the emergence and commercialization of multiple open source SIP switching systems, enterprise-level multimedia applications based on SIP switches, such as IP phones, video phones, and video conferencing, have been more and more widely used around the world. These IP-based SIP multim...
