Service multiplexing method for Ethernet

Abstract

The present invention discloses a method for service multiplexing of Ethernet, comprising the following steps that: after a data frame accesses the Ethernet through a user network interface of a source site, the client identifier of the data frame is determined according to the characteristic information of the data frame; the guest site of the data frame is determined according to the determined client identifier, or according to the destination address in the client identifier and data frame, the data frames with the same guest site and the same client identifier are encapsulated in a path, and a path identifier is added on the path; the paths with the same guest site are bound in one channel, the data frames in the channel are sent after the channel layer encapsulation of the paths in the channel is carried out; the encapsulation of the channel layer is released after the data frames in the channel are received, and the output port of the data frames is determined and the encapsulation of the paths is released according to the path identifier or according to the path identifier and the destination address; an output port of the data frame is determined; after the encapsulations of the channel layer and the paths are released, the obtained data frame is outputted to the determined output port.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a service multiplexing method for Ethernet. Background technique [0002] Driven by the IP trend of telecommunication services, the services carried by the transmission network are changing from Time Division Multiple Access (TDM) to IP-based, and the corresponding service interfaces are also changing from traditional Synchronous Digital Hierarchy (SDH), Pseudosynchronous Digital Hierarchy (PDH) interfaces are mainly transformed into packet service interfaces, while Ethernet has become a relatively common service access method and gradually becomes the mainstream service in the transport network. [0003] However, how to transmit Ethernet services with high efficiency and high quality in the transport network, which can not only achieve the purpose of bandwidth sharing, but also ensure the quality of service (Quality of Service, QoS) of the business, has become a ke...

Problems solved by technology

[0007] The present invention is made in consideration of the above-mentioned problems. For this reason, the main purpose of the present invention is to provide a business multiplexing scheme for Ethernet, to solve the problem in the related art that the mutual isolation between services and the QoS of each service cannot be taken into account. question
