Title:
MULTICAST SYSTEM AND MULTICAST METHOD FOR IDENTIFIER RESOLUTION-BASED ROUTING
Document Type and Number:
WIPO Patent Application WO/2022/082825
Kind Code:
A1
Abstract:
The present invention relates to the technical field of network communication and data processing, and relates in particular to a multicast system for identifier resolution-based routing. The system comprises a multicast source, multicast receivers, multicast member agents, and multicast processing nodes. The system further comprises an identifier resolution service module deployed in the cloud or in a network. The module uses a global unique identifier unrelated to any network addresses as a multicast identifier capable of uniquely identifying a multicast service, while IP network addresses are still used as network addresses. The module is further used to maintain mapping relationships between the multicast identifier and IP network addresses of one or more multicast processing nodes, and to provide registration, deregistration, and resolution and query services. Network nodes hosting a multicast bearer service comprise the multicast processing nodes and IP network routing and switching nodes. The multicast receivers apply to join the multicast service by means of the multicast identifier.
