Summary:Disclosed are a client device, a routing device and a server device for re-establishing an anycast communication session with a service function (SF) and corresponding methods of operating the same. The client device comprises a processor, being configured to: obtain a trigger for the re-establishing of the anycast communication session; send a calibration request message (CREQ) to a routing device being adjacent to the client device; and receive a calibration response message (CRES) from the routing device. The CREQ comprises the identifier (SID) of the SF, a locator address (IPC) of the client device, and a locator address (IPS) of a particular server device of the SF currently serving the client device. The CRES comprises the SID of the SF, the IPC, and a locator address (IPS') of a specific server device of the SF prospectively serving the client device. L'invention divulgue un dispositif client, un dispositif de routage et un dispositif serveur pour rétablir une session de communication anycast avec une fonction de service (SF) et des procédés de fonctionnement correspondants à ceux-ci. Le dispositif client comprend un processeur, configuré pour : obtenir un déclenchement du rétablissement de la session de communication anycast ; envoyer un message de demande d'étalonnage (CREQ) à un dispositif de routage adjacent au dispositif client ; et recevoir un message de réponse d'étalonnage (CRES) du dispositif de routage. Le CREQ comprend l'identifiant (SID) de la SF, une adresse de localisation (IPC) du dispositif client, et une adresse de localisation (IPS) d'un dispositif serveur particulier de la SF qui dessert actuellement le dispositif client. Le CRES comprend le SID de la SF, l'IPC, et une adresse de localisation (IPS') d'un dispositif serveur spécifique de la SF qui dessert de manière prospective le dispositif client.
