Patent

CA 2458481

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.

L'invention concerne un moteur de traduction pour traduire de manière efficace des trames SDH/SONET (101) en trames Ethernet (105) et inversement. Dans un mode de réalisation, un système de traduction comprend un tampon (103) pour conserver les trames SDH/SONET (101) et Ethernet (105). La présente invention porte également sur une adresse de contrôle d'accès au support (MAC) Ethernet pour un emplacement SDH/SONET TDM (103E -103F) correspondant. Selon l'invention, un moteur de traduction destiné à traduire les trames SDH/SONET (101) en trames Ethernet (105) est en communication avec une interface de sortie. Les données utiles SDH/SONET (101 A) sont envoyées au moteur de traduction qui les traduit en données utiles Ethernet (105 A). Le processus inverse a lieu pour traduire d'Ethernet en SDH/SONET.
