Slave node data interconnecting device, method and system base on one point to several points network

Abstract

The embodiment provides a data inter-communication method, device and system for slave node based on one point-to-multiple points network. The method comprises obtaining data sent by the communication triggering slave node; obtaining destination address of the data from the obtained data; searching the logic link label corresponding to the destination address of the data in corresponding relation between the logic link label and the data address according to the obtained destination address of the data; sending obtained data to a destination logic link according to data destination address obtained by the search and corresponding logic link label. The invention overcomes the impact of the data intercommunication between nodes to the system in prior art, makes application scene return to flexibility of the Ethernet.

Description

technical field [0001] The invention relates to a broadband communication system, in particular to a device, method and system for data intercommunication between slave nodes in a point-to-multipoint network. Background technique [0002] The broadband communication system mainly includes a point-to-point system and a point-to-multipoint (P2MP, Point to Multipoint) system. Wherein, the point-to-point system mainly refers to: a master node and a single slave node in the system are connected through a physical point-to-point link, such as a digital subscriber line system (DSL, Digital Subscriber Line). The point-to-multipoint system mainly refers to: a master node and multiple slave nodes in the system are connected through a physically multiplexed link, such as a passive optical network (PON, Passive Optical Network) system. [0003] figure 1 It is a schematic structural diagram of a point-to-multipoint PON system in the prior art. The PON system consists of a master stati...

Problems solved by technology

[0005] In the process of realizing the present invention, the inventor has found that there are at least the following problems in the prior art: under the networking architecture of the prior art 2, the Ethernet service flow between different slave nodes (such as ONT in PON) under the same P2MP system To intercommunicate, if these Ethernet traffic flows to the master node are not marked with a virtual local area network tag (Virtual Local Area Network Tag VLAN Tag) or are in the same virtual local area network (Virtual Local Area Network VLAN), they will be aggregated and interconnected in the Ethernet switch module are discarded, making it impossible to communicate with

The problem with this is that it puts constraints and restrictions on VLAN planning and application scenarios, and changes the freedom of using the original Ethernet.
