Description

A communications scheme for configuring a network comprising a plurality of connected switching apparatus, each switching apparatus having functionality for implementing connectionless forwarding of received communications traffic to selectively provide a connection-oriented service for said received communications traffic, the scheme comprising: determining in a control plane index header field values to identify connectionless traffic received at switching apparatus for which a connection is to be established between a source node and a destination node; providing each switching apparatus necessary to implement the connection with information from the control plae, the information enabling the data forwarding tables of the switching to be populated with said index header field values in association with egress ports of the switching apparatus; and disabling all other functionality on said switching apparatus capable of populating the data forwarding tables with index information associated with said egress ports of the switching apparatus necessary to establish said connection.

L'invention concerne un programme de communication destiné à configurer un réseau comprenant plusieurs appareils à commutation connectés, chacun ayant une fonctionnalité pour mettre en oeuvre le transfert non connecté de communications reçues afin de fournir de manière sélective un service en mode connexion auxdites communications reçues. Ledit programme consiste à déterminer des valeurs de champs d'en-tête d'index de plan de commande pour identifier un trafic non connecté reçu au niveau de l'appareil de commutation pour lequel une connexion doit être établie entre un noeud source et un noeud destination; à prévoir chaque appareil de commutation requis pour mettre en oeuvre la connexion des informations provenant du plan de commande, les informations permettant aux tables de transfert de données de l'appareil de commutation de se garnir desdites valeurs de champs d'en-tête d'index en association avec des ports de sortie de l'appareil de commutation, et à désactiver toutes les autres fonctionnalités sur ledit appareil de commutation susceptibles de garnir les tables de transfert de données avec des informations d'index associées auxdits ports de sortie de l'appareil de commutation requis pour établir ladite connexion.
