Network transmission control method and system

Abstract

The provided network transmission control method for network transmission multicast business can detect the occupancy of network bandwidth to decide whether the bandwidth can support new business, if not, rejects the new business request for multicast business QoS.

Description

technical field [0001] The invention relates to the communication field, and particularly discloses a network transmission control method and system. Background technique [0002] In today's world, network technology is developing rapidly. As the network speed becomes faster and faster, the services carried by the network are becoming more and more diverse. As more and more services in the telecommunications network become IP-based, multi-service integration (Multi-Play) has become a trend in current network construction. Voice over IP (VoIP) services, Internet TV (IPTV) and Internet (Internet) access, etc. Services are gradually integrated into one network for operation, which can greatly reduce the network construction and network maintenance costs of telecom operators, and at the same time provide convenient, fast and flexible value-added services. Therefore, multi-service integration has become an irresistible development trend in the current network development. . [...

AI Technical Summary

Problems solved by technology

[0016] 1. BTV and VOD generally operate on the same network, and the equipment has a certain degree of integration. This method can only guarantee the CAC of the on-demand service, but not the CAC of the multicast service. It is believed that the CAC of the multicast service is guaranteed through network planning, but in fact It is likely that there are other services with higher priority operating in the same network (especially the access network), which may cause all multicast services to be blocked at the same time in the case of a burst of higher priority services;

[0017] 2. The existing technical solution needs to save the topology of the entire IPTV network on the RM, and the entire routing situation of the video stream needs to be known in advance, so that when the user requests the video stream, the corresponding network device can be queried for the corresponding port through which the video stream passes bandwidth occupancy (or record all resource information in the RM database), so the requirements for RM are high, and RM needs to be re-synchronized or calculated in the case of routing changes;

[0018] 3. The existing technical solution requires RM to obtain the user's location information from AMS, which increases the interaction between AMS and RM and the resulting resource consumption and uncertainty, such as the possible network interruption between RM and AMS. as a result of

[0019] Similarly, in addition to BTV, other multicast services are also facing the same problem as BTV due to insufficient bandwidth, which causes the overall transmission quality to decline.
