A multicast/unicast admission control method, a multicast/unicast admission control device, and a multicast/unicast admission control system are provided. In the method, through centralized resource control of a resource and admission control subsystem (RACS), sharing of multicast/unicast resources is realized. The RACS allocates and authorizes resources to an access node (AN), the AN manages the obtained multicast resources under the authorization, and the resource allocation is adjusted through interaction when the multicast resources of the AN or the resources of the RACS are not sufficient.

Multicast/unicast admission control method, device and system

The present disclosure relates to the field of communications, and discloses a method for determining path pre-congestion. The method is applicable to an Ethernet path. Pre-congestion is determined and flagged through an ingress node or an intermediate node in the Ethernet path, and a pre-congestion status indication packet is sent by an egress node to the ingress node or a policy server, so that the ingress node or the policy server obtains pre-congestion information of the Ethernet path, and notify an application function entity AF of performing admission control. When the method in the present disclosure is used, problems of packet loss and excessively long time delay caused by the conventional congestion control technology may be avoided, thereby ensuring user experience of existing services.

Method, apparatus, and system for judging path congestion

A method, device and system for managing resources in networks are provided, which relate to the field of data communication. The method includes the following steps. A resource manager (RM) sends a first request message according to a received resource request message, to request an access node (AN) to perform admission control. After receiving an admission control result indicating whether a resource requested by the resource request message is admitted, the RM sends a response message of the resource request message. Therefore, when multicast/unicast connection admission control (CAC) that supports shared bandwidth is realized, flow fusions of user line configuration between the AN and a broadband remote access system (BRAS, and policy distribution between a resource and admission control subsystem (RACS) and the BRAS are guaranteed; and sharing of bandwidth resources is realized to avoid waste of the bandwidth resources.

Method, device and system for managing resources in networks

The present invention relates to the field of communications technologies, and discloses a method, an apparatus, and a system for allocating Internet Protocol Television (IPTV) resources to save bandwidth resources in the IPTV service. The method includes the following: a multicast access control entity allocates resources to a unicast access control entity through an intermediate network entity when unicast resources are not enough; and the unicast access control entity allocates resources to the multicast access control entity through the intermediate network entity when multicast resources are not enough. The present invention is primarily applicable to IPTV technologies.
