Abstract

New layer of data link layer protocol - data link procedure (DLP) is introduced in the invention to realize syncretizing adaptation between Ethernet and SDH / SONET in order to overcome shortage of current adaptation technique including not matched interface speed, not supporting dynamic bandwidth allocation based on packets, and not possible to transmit SDH / SONET on Ethernet, not compatible to IP and packet voice service etc. The method realizes direct transmission of Ethernet on SDH / SONET, and SDH / SONET on Ethernet as well as realizes compatibility to IP network and packet voice network. Using safety mechanism, network control management mechanism, flow management mechanism provided by DLP realizes network management control function such as two layer protected rearrangement, performance management, fault management etc. The method makes current communication network transits to united public network in next generation of using packet switching technology smoothly.

Description

Invention field

[0001] The present invention belongs to the field of data transmission between Ethernet and synchronous digital system or synchronous optical network. It is an adaptation method used for the integration of Ethernet and synchronous digital system or synchronous optical network, and specifically is how to use synchronous digital system ( The English abbreviation is SDH) or synchronous optical network (English abbreviation is SONET) to transmit Ethernet and how to transmit synchronous digital system or synchronous optical network on Ethernet. More specifically, how to transmit Ethernet on SDH / SONET network / Fast Ethernet / Gigabit Ethernet / 10G Ethernet and how to transmit SDH / SONET on Ethernet / Fast Ethernet / Gigabit Ethernet / 10G Ethernet. The concept of the present invention is mainly used for various Ethernet or Various communication devices that synchronize digital systems or synchronize optical network interfaces, such as various routers (core or high-end switching ro...
