Resource management device and method in multicast service

Abstract

The invention discloses a resource management device and method in a multicast service. The method includes: a system management module initializes the total amount of resources, a resource sharing policy, and the number of high and low priority resource pools; the high and low priority resource pools apply for themselves capacity of resource pools, and configure sharing policies between resource pools and local resource pools; after receiving multicast resource application requests, resource pools with high and low priority allocate resource blocks according to the sharing policies. After the resource release request of the resource block is reclaimed. Using the device and method can fully utilize the replication capability of the system while ensuring the service quality of the multicast service.

Description

technical field [0001] The present invention relates to the multicast technology in the field of communication, in particular to a resource management device and method in the multicast service. Background technique [0002] In the field of communication, multicast (Multicast) transmission is a forwarding method in which a single data source sends and multiple receiving sources receive, which realizes efficient point-to-multipoint data transmission, can save network bandwidth, and can reduce network load. For any communication system, the typical multicast technology is to use a physical chip to copy a single input multicast data packet on multiple physical queues at the exit, or even realize multiple copies on a single physical queue to form multiple single Broadcast data packets to achieve the purpose of multicast, such as figure 1 shown. The realization of these technologies must involve the management and allocation of resources, such as: physical queues and replicatio...

Problems solved by technology

If special emphasis is placed on the replication capability, it will definitely have a negative impact on the quality of service of multicast. For example, due to limited system resources, the system may not be able to operate normally when performing replication operations.

In particular, for systems with multicast quality of service requirements, the system may not work properly

If special emphasis is placed on the quality of service, it may reduce the system's ability to replicate and fail to complete all the replication work, resulting in a decline in the system's ability to work
