Embodiment Construction

[0028] An illustrative embodiment of the invention relates to converting SDH / SONET frames to Ethernet frames, and converting Ethernet frames to SDH / SONET frames. It is best to activate the voice network to transmit data and activate the data network to transmit voice signals. Ethernet is a well-known network technology for transmitting data signals, and SDH / SONET is a well-known network technology for voice transmission. As technology develops, the need to send voice over Ethernet structures and data over SDH / SONET structures is increasing. Therefore, conversion between SDH / SONET and Ethernet is required.

[0029] The conversion used here is the process of mapping the Ethernet MAC address to the corresponding SDH / SONET TDM time slice, and the conversion is from SDH / SONET frame to Ethernet frame and from Ethernet frame to SDH / SONET frame . Said conversion may include supporting SDH / SONET payload and overhead.

Abstract

A translation engine is provided for efficiently translating SDH / SONET frames (101) to Ethernet frames (105) and vice versa. In accordance with one embodiment, a translation system includes a buffer (103) for holding SDH / SONET (101) and Ethernet frames (105). An Ethernet Media Access Control (MAC) address for a corresponding SDH / SONET TDM slot (103 E-103 F) further provided. A translation engine for translating SDH / SONET frames (101) into Ethernet frames (105) is in communication with an output interface. The SDH / SONET payload (101 A) is sent through a translation engine to translate the SDH / SONET payload (101 A) into an Ethernet payload (105 A). For translating from Ethernet to SDH / SONET, a reverse process occurs.

Description

[0001] related application [0002] This application claims priority from US Provisional Application No. 60 / 314,801, which was published on August 24, 2001, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a network switching structure, in particular to mapping or converting SDH / SONET frame structure (framing) to Ethernet frame structure, and mapping or converting Ethernet structure to SDH / SONET structure. Background technique [0004] Many Metropolitan Area Networks (MANs) and Wide Area Networks (WANs) use Time Division Multiplexing (TDM) Synchronous Optical Network (SONET) network architectures, or Synchronous Digital Hierarchy (SDH) network architectures. In contrast, many local area networks (LANs) use an Ethernet architecture. [0005] The SDH / SONET standard was originally used in the voice network and has been developed since then. SDH is a European version of a standard that is basically th...
