Abstract

The embodiment of the invention discloses a message cross-board multicast copying and forwarding method and system based on a CLOS framework. The method comprises the following steps: a switching chip of a service line card filters an original message, obtains a message needing to be processed by an advanced logic processing chip, sends the message to the advanced logic processing chip of the service line card for processing according to a homologous homoclinic balance mode, determines a private message needing to be shared, packages the private message, and forwards the private message to the switching chip; the switching chip identifies the type of the message, determines an algorithm matched with the type, and selects a target port from the ports where the switching chip is connected with the switching line card to forward the private message to the switching line card according to the algorithm; and the switching line card receives the private messages to complete multicast copying, and forwards the private messages to the target service line card. According to the invention, the function of private message multicast forwarding under the CLOS architecture can be realized, and the method has universality.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and system for cross-board multicast replication and forwarding of messages based on a CLOS architecture. Background technique [0002] With the rapid growth of network traffic, the traditional convergence and distribution devices are gradually evolving to be based on the CLOS architecture. The CLOS architecture defines a geometric topology, which is mainly composed of the main control card, line-card and switching line. Card (Fabric-card) composition. The CLOS architecture completely separates the control plane and the data plane. On the one hand, the switching line card acts as the forwarding center of the system, which greatly improves the forwarding capability of the system. On the other hand, it greatly improves the reliability of the forwarding plane and avoids the control plane. The impact of the fault on the forwarding plane. [0003] In ...
