Service communication method and system for access network apparatus

摘要

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.

1. A service communication method for an access network device, wherein the access network device comprises a source terminal and a target terminal jointly connected to one and a same access switch, and the method comprises:
notifying, by a node server according to a request for a current service, the access switch to which the source terminal and the target terminal are jointly connected to set, in the access switch's internal data packet address table, a downlink port of the access switch to which a data packet of the current service is to be oriented; sending, by the source terminal, an uplink data packet of the current service; and orienting, by the access switch, the data packet to the downlink port according to settings of its internal data packet address table after receiving the data packet, and transferring the data packet to the target terminal via the downlink port; wherein when the data packet is a unicast data packet, the data packet address table is a unicast data packet address table, and a destination address of the data packet is a receiving-party address during unicast service communication; and wherein the request for the current service is a request initiated by the source terminal for establishing unicast service communication with the target terminal, and the node server notifying the access switch to set the data packet address table comprises: acquiring, by the node server, communication link information of the current service according to the request for the current service, wherein the communication link information comprises information on a downlink port of the access switch to which the target terminal is connected; sending, by the node server, a port configuration protocol packet to the access switch according to the communication link information; and setting, by the access switch in its internal data packet address table according to the port configuration protocol packet, a downlink port to which a data packet with a destination address being an address of the target terminal is to be oriented; or the request for the current service comprises a request initiated by the source terminal for establishing unicast service communication with the target terminal, and the node server notifying the access switch to set the data packet address table comprises: acquiring, by the node server, communication link information of the current service according to the request for the current service, wherein the communication link information comprises information on the downlink port of the access switch to which the source terminal is connected and information on a downlink port of the access switch to which the target terminal is connected; sending, by the node server, a port configuration protocol packet to the access switch according to the communication link information; and setting, by the access switch, in its internal data packet address table according to the port configuration protocol packet, a downlink port to which a data packet with the destination address being an address of the source terminal is to be oriented and a downlink port to which a data packet with a destination address being an address of the target terminal is to be oriented.
