Service communication method of access network device and system thereof

Abstract

A service communication method for an access network apparatus. The access network apparatus comprises a source terminal and a target terminal both connected to the same access switch. The method comprises: a node server, according to a request of a current service, notifying the access switch connected to both the source terminal and the target terminal to set a downlink port of the access switch, to which a data packet of the current service is directed, in an internal data packet address table thereof; the source terminal sending an uplink data packet of the current service; and after receiving the data packet, the access switch directing the data packet to the corresponding downlink port according to the setting of the internal data packet address table thereof, and transmitting the data packet to the target terminal through the downlink port. The present invention can effectively save the bandwidth and routing resources, ensure a steady and smooth transmission path, avoid delay of multimedia services, satisfy national information security requirements, and save hardware resources, thereby ensuring network transmission quality.

Description

technical field [0001] The present invention relates to the technical field of novel networks, in particular to a service communication method for access network equipment, a service communication system for access network equipment, a node server and an access switch. Background technique [0002] New types of networks, including the Internet, enable the exchange of information and other information resources between different individuals and institutions. Networks usually include technologies such as access, transmission, signaling, and network management. Such techniques have been described extensively in the literature. This is summarized in: "Telecommunications Convergence" by Steven Shepherd (McGraw-Hill, 2000), "The Essential Guide. to Telecommunications" Third Edition by Annabel Z. Dodd (Prentice Hall PRT, 2001), Or Communications Systems and Networks, Second Edition by Ray Horak (M&T Books, 2000). Past advances in these technologies have substantially increased t...

Problems solved by technology

[0036] Current equipment manufacturers recommend dozens or even hundreds of megabits of ultra-broadband access networks for each household. Even if each household has fiber-to-the-home, it is still difficult to provide consumers with quality-assured video communication services

No matter how complicated the QoS method is, it can only "improve" the transmission quality of the IP Internet at best, but cannot "guarantee" the network transmission quality
