Problems solved by technology

[0005] Since it is impossible to evaluate the load of the entire network, especially in different time periods and different types of multicast services, the requirements for the deployment of aggregation points are different. As the complexity of the network increases, it is difficult to determine the deployment of aggregation points from an intuitive perspective. best

Embodiment Construction

[0054]In the software-defined network (Software-Defined Networking, SDN) architecture, the SDN controller establishes a connection with all network devices, and can obtain information such as the status, resources, and protocol operation of all network devices in real time, and issue control commands to control Add and delete table entries of network devices, perform service configuration, traffic optimization and monitoring, etc. In short, the SDN controller can keep connected with each network device, obtain the status of the network device in real time, and control the network device.

[0055] In order to achieve the purpose of the present invention, the present invention utilizes the SDN controller to monitor in real time the distribution of multicast traffic on a certain aggregation point in the entire network, count the consumption of network bandwidth by service traffic, and accumulate relevant historical data to deploy Provide a basis for the choice of , and at the sam...

Abstract

The invention provides a method and device for dynamically deploying rendezvous points in two-way protocol independent multicast. The method and device are applied to SDN controllers. The method includes the steps that firstly, local network load metric values of all network equipment are collected at the interval of first preset time; secondly, the local network load metric values of all the network equipment are gathered to generate a metric value of the whole network load; thirdly, when the starting condition for deploying the rendezvous points again is met, new candidate rendezvous points are determined, and after all the new determined candidate rendezvous points take effects, the metric value of the whole network load is obtained in a pre-analog computation mode; fourthly, according to the whole network load metric value which is obtained in the pre-analog computation mode and corresponds to the situation after all the new candidate rendezvous points take effects and the whole network load metric value corresponding to the current rendezvous points, optimum rendezvous points at present are determined, and the step for deploying the rendezvous points again is carried out. The method and device can dynamically deploy the rendezvous points according to the network load condition and the distribution changing condition of multicast services, multicast sources and multicast receivers.

Description

technical field [0001] The present invention relates to the technical field of bidirectional protocol-independent multicast (Bidir-PIM, Bi-directional protocol independent Multicast), in particular to a dynamic deployment of convergence points in bidirectional protocol-independent multicast in a software-defined network (Software-Defined Networking, SDN) architecture method and device. Background technique [0002] Bi-directional Protocol Independent Multicast (Bidir-PIM, Bi-directional Protocol Independent Multicast), its basic principle is: use the multicast entry (*, G) to forward, does not distinguish the source multicast streams in the source direction. A rendezvous point (Rendezvous Point, rendezvous point) is used as the root of a multicast distribution tree for a series of multicast groups. [0003] Bidirectional protocol-independent multicast uses shared tree convergence points for multicast data forwarding. All multicast traffic must be sent to the convergence po...
