The invention discloses a switch system and a communication method, and relates to the field of computer networks. The switch system includes: a controller cluster, including at least one software-defined network controller, an agent cluster, including at least one agent device, and, several switches; wherein, the agent cluster is located between the controller cluster and the switch, and each agent device Proxying several switches to establish communication connections with software-defined network controllers in a controller cluster. By setting up a proxy cluster between the controller cluster and the switch, and using each proxy device in the proxy cluster to act as a proxy for several switches, and establish a communication connection with the SDN controller in the controller cluster, the SDN controller in the controller cluster can be reduced. The number of connections reduces the performance consumption of the SDN controller and improves the processing performance of the SDN controller.
Description
technical field [0001] The invention relates to the field of computer networks, in particular to an exchange system and a communication method. Background technique [0002] SDN (Software Defined Network) realizes flexible control of network traffic by separating the control plane and data plane of network devices. [0003] However, the performance of the SDN controller becomes a new bottleneck. Take the SDN controller using the OpenFlow protocol to communicate with the switch as an example. Each switch needs to establish a TCP (Transmission Control Protocol, Transmission Control Protocol) connection with the SDN controller separately. In the case of redundant protection, a switch must communicate with the SDN control at the same time. The switches establish 2-3 TCP connections, and each switch independently sends OpenFlow packets to interact with the controller. When large-scale online or service distribution occurs, the SDN controller may generate a large amount of perfo...
