Patent CA-2439726-A1 (CA)

IPC: H04L45/50
Filed: 2002-03-06
Abstract: Un réseau de données (11) de protocole Internet (IP) validé par commutation d'étiquettes de protocole multiple (MPLS) est capable de transmettre des données à un deuxième réseau (13) IP validé par MPLS par l'intermédiaire d'un réseau optique à champ partagé (12), qui serait sinon incapable de gérer les protocoles d'interface de réseau utilisateur (UNI) devant être utilisés dans un environnement de réseau MPLS, au moyen de la configuration du réseau optique à champ partagé (12) et de son système classique (16) de gestion de réseau (TNMS), de façon à simuler ou à émuler un réseau optique validé par MPLS. La simulation/émulation du réseau MPLS s'effectue comme suit: quand un premier élément (NE) (14a) du réseau à champ partagé reçoit une demande de connexion (demande UNI) du réseau MPLS (11) sous un protocole UNI, la demande UNI est transmise (.fwdarw.A) au TNMS (16), qui établit ensuite (.fwdarw.B) la connexion demandée à travers le réseau à champ partagé (12) par l'intermédiaire d'un deuxième NE périphérique (14b) vers un NE du deuxième réseau IP (13). Une fois que la connexion est établie, le TNMS (16) commande (.fwdarw. C) au NE périphérique (14a) d'envoyer un signal de retour au réseau demandeur (11) indiquant que la connexion a été établie avec succès. Des paquets de données peuvent ensuite être transmis à travers le réseau (11, 12, 13). Dans le cas (figure 4) où le réseau optique (20) contient également des réseaux optiques validés par MPLS (21b, 23b), le procédé de simulation/émulation peut, de plus, consister en une étape dans laquelle le TNMS (26) commande .fwdarw.X au deuxième NE (24b) d'envoyer une demande UNI au réseau optique (23b) validé par MPLS demandant une connexion avec le deuxième réseau IP (23a). Un signal de retour indiquant que la connexion a été établie, reçu par le deuxième NE (24b) du réseau optique (23b) validé par MPLS est envoyé (.fwdarw.Y) au TNMS (26), qui, à réception dudit signal, commande (.fwdarw.C) au NE périphérique (24a) d'envoyer un signal de retour au réseau demandeur (21b).

Title: Method and apparatus for critical time multimedia data transmission
Inventor: TURNBULL RORY STEWART
IPC: H04L12/54
Filed: 2002-11-29
Abstract: The invention involves a refinement to conventional data transmi ssion over packet networks (e.g. IP). Conventionally, multimedia streaming systems use either a reliable protocol (e.g. TCP) or an unreliable protocol (e.g. UDP) for the media transmission. Each method has its own benefits. Using a reliable protocol ensures that all the packets arrive at the receiver, but this does require more bandwidth due to protocol overheads and it introduces more delay.  An unreliable protocol is lightweight and faster although the data stream may be subjected to packet loss. In the present invention a combination of both protocols is used, where an unreliable protocol is employed initially followed by a reliable protocol at the end of the media clip. The unreliable protocol is used for the low delay transmission of packets while the reliable protocol at the end is used for the transmission of packets that were initially lost.
