Title (EN) DATA TRANSMISSION APPARATUS AND METHOD FOR TRANSMITTING DATA BETWEEN PHYSICAL LAYER SIDE DEVICE AND NETWORK LAYER DEVICE
(FR) DISPOSITIF ET PROCEDE DE TRANSMISSION DE DONNEES ENTRE UN DISPOSITIF A COUCHE PHYSIQUE ET UN DISPOSITIF A COUCHE RESEAU
Abstract:
(EN) The present invention discloses a data transmission apparatus and method for transmitting data between physical layer side device and network layer device, which encapsulating a novel LAPS framing-de-framing into SPE/VC of an HDLC-like frame using a variable SAPI value. The LAPS encapsulation consists of the start Flag Sequence, address field (SAPI, Service Access Point Identifier), control field (0x03), Information field (Ipv4, Ipv6, or PPP protocol data unit), FCS (Frame check sequence) and the ending Flag Sequence. The Flag Sequence (0x7E) identifies the beginning/end of a LAPS frame. The present invention can be used to adapt Internet/Intranet to telecommunication infrastructure, and can be applied to network devices such as core and edge routers, switch devices, IP based network accessing equipment, line cards, and interfacing units used in high speed, e.g. Gigabit applications, for adapting IP directly to SDH/SONET or simplified SDH/SONET, or other physical layer devices.
(FR) L'invention concerne un dispositif et un procédé de transmission de données entre un dispositif à couche physique et un dispositif à couche réseau permettant d'encapsuler un nouveau LAPS de tramage en SPE/VC d'une trame de type HDLC grâce à une valeur SAPI variable. L'encapsulation LAPS consiste en une séquence d'indication de début, un champ d'adresses (SAPI, Identificateur du point d'accès de service), un champ de contrôle (0x03), un champ d'information (Ipv4, Ipv6 ou unité de données de protocole PPP), FCS (séquence de vérification de la trame) et la séquence d'indication de fin. La séquence d'indication (0x7E) identifie le début/fin de la trame LAPS. L'invention permet d'adapter Internet/Intranet à une infrastructure de télécommunication et peut être appliquée à des dispositifs réseau tels que des routeurs principaux (core router) et routeurs de délignage (edger router), des dispositifs de commutation, un équipement d'accès au réseau IP, des cartes de ligne et des unités d'interfaçage assurant un haut débit, notamment des applications Gigabit, permettant l'adaptation IP directe à SDH/SONET ou SDH/SONET simplifié ou à d'autres dispositifs à couches physiques.
