Embodiment Construction

[0060] The specific embodiments of the present invention will be described in detail below with reference to the drawings.

[0061] How to introduce RPR technology to the E1 transmission platform is a very important method of the present invention. Here, the implementation of RPR on E1 is called RPR OVER E1. An object of the present invention is to provide a method to organize multiple E1 links to transmit Ethernet messages. This mapping method enables RPR OVER E1 to form a ring based on E1, which can be dynamically based on the actual bandwidth of the data service. Adjust the number of E1 links used to transmit Ethernet packets, so as to achieve dynamic adjustment of data transmission link bandwidth.

[0062] First, the inverse multiplexing technology utilizes multiple E1 resources to transmit data services with a bandwidth greater than E1. Inverse multiplexing is to adapt one high-speed data to multiple low-speed channels for transmission, providing bandwidth equivalent to the s...

Abstract

This invention relates to a method of the Ethernet transferring in several E1 channels, characterized in that it uses carrying platform to transfer Ethernet, wherein the carrying platform uses several E1 as the physics layer of the RPR; it applies MPLS agreement and RPR agreement to enclose the Ethernet message; for the group with RPR format, using backward multiply usage method to transfer in several E1, adjusting the belt width through increasing or decreasing the number of E1 channel; it also can build loop based on E1, making several technical index of MPLS and RPS transferring in E1 channel.

Description

Technical field [0001] The invention relates to a method for Ethernet transmission in multiple E1 channels, in particular to a method for adapting one high-speed data to multiple E1 channels for transmission. Background technique [0002] The traditional E1 platform access data service method is roughly divided into two kinds. One is the exchange of E1 and Ethernet protocol converters. Usually one Ethernet port corresponds to one E1 channel. This method simply encapsulates the Ethernet message into the E1 frame structure without any protocol encapsulation, and can only be transmitted point-to-point. It is a simple transparent transmission of Ethernet packets. [0003] The other is that one Ethernet port corresponds to multiple E1 channels. The multiplexing mode can be byte interleaving, or packet interleaving, which means that packets are transmitted on multiple E1 in turn. The packet interleaving method is efficient Not high, the above method does not perform any encapsulation, ...
