Title
(EN) CROSS-DOMAIN CONTROL PLANE COLLABORATION FOR END-TO-END SRv6 SLA CONSTRAINED SERVICE DELIVERY
(FR) COLLABORATION DE PLAN DE COMMANDE DE DOMAINES CROISÉS DESTINÉE À UNE DISTRIBUTION DE SERVICE CONTRAINTE SRV6 SLA DE BOUT EN BOUT
Abstract
(EN)
Technologies for end-to-end SRv6 service delivery comprise transmitting an access authentication/NAS signaling message specifying requested services in a fifth-generation (5G) network environment. Service requirements are determined for each requested service, and used to generate an SLA-specific request. For each SLA-specific request, a first bidirectional path is instantiated through a core portion of the 5G network and a first Segment Routing for IPv6 (SRv6) segment stack is generated corresponding to the first path. A first SLA-Binding SID associates the first SRv6 segment stack with its SLA-specific request. A second bidirectional path is instantiated through a backhaul network connecting to the core portion of the 5G network and a second SRv6 segment stack is generated corresponding to the second path. A second SLA-Binding SID associates the second SRv6 segment stack with the same SLA-specific request, and the first SLA-Binding SID is appended to as the last segment of the second SRv6 segment stack.

L'invention concerne des technologies de distribution de service SRv6 de bout en bout comprenant la transmission d'un message de signalisation d'authentification d'accès/NAS spécifiant des services demandés dans un environnement de réseau de cinquième génération (5G). Des exigences de service sont déterminées pour chaque service demandé et utilisées pour générer une demande spécifique au SLA. Pour chaque demande spécifique au SLA, un premier chemin bidirectionnel est instancié à travers une partie centrale du réseau 5G et un premier routage de segment pour un empilement de segments IPv6 (SRv6) est généré correspondant au premier trajet. Un premier SID de liaison SLA associe le premier empilement de segments SRv6 à sa demande spécifique au SLA. Un second trajet bidirectionnel est instancié à travers un réseau de liaison terrestre connecté à la partie centrale du réseau 5G et un second empilement de segments SRv6 est généré correspondant au second trajet. Un second SID de liaison SLA associe le second empilement de segments SRv6 à la même demande spécifique au SLA, et la première SID de liaison SLA est annexée au dernier segment du second empilement de segments SRv6.
