Abstract
(EN)
The present invention relates to the field of monitoring, and more particularly, relates to a P2P-based service communication method, device and system. The method comprises: receiving a first packet comprising a first identifier and first data, the first identifier being used to identify an apparatus and a service provided thereby, and the first data being used to request a corresponding service module in the apparatus to perform an operation to provide the service; determining an apparatus identifier and a service type corresponding to the service identified by the first identifier; and if a P2P link for the apparatus corresponding to the apparatus identifier exists, sending a second packet to the apparatus by means of the P2P link, the second packet comprising the service type and the first data. The invention can reduce network delays.

La présente invention se rapporte au domaine de surveillance, plus particulièrement, à un procédé, un système et un dispositif de communication de service basé sur P2P. Le procédé consiste à : recevoir un premier paquet comprenant un premier identifiant et des premières données, le premier identifiant étant utilisé pour identifier un appareil et un service fourni par celui-ci et les premières données étant utilisées pour demander à un module de service correspondant dans l'appareil d'effectuer une opération pour fournir le service ; déterminer un identifiant d'appareil et un type de service correspondant au service identifié par le premier identifiant ; et si une liaison P2P pour l'appareil correspondant à l'identifiant d'appareil existe, envoyer un second paquet à l'appareil au moyen de la liaison P2P, le second paquet comprenant le type de service et les premières données. L'invention permet de réduire les délais de réseau.
