Embodiment Construction

[0041] The present invention will be further described now in conjunction with accompanying drawing.

[0042] The principle of the forwarding processing method of the data message in the access gateway of the present invention is: when a certain terminal does not register with the access gateway, the access gateway does not recognize the uplink and downlink data of the terminal, and the uplink and downlink data of the terminal Transparent transmission; when a terminal registers with the access gateway, the access gateway identifies the uplink and downlink data of the terminal, transparently transmits the uplink data, and optimizes the transmission of the downlink data, so as to speed up the data forwarding rate and reduce the MAC table The frequency of item updates, for the purpose of reducing system load.

[0043] In order to realize the above principle, two types of MAC forwarding tables are set in the access gateway: MAC forwarding tables of registered terminals and MAC for...

Abstract

The present invention relates to a data packet forwarding processing method in an access gateway, comprising: an access gateway receiving a data packet; the access gateway performing learning based on a source MAC address of the packet and constructing a MAC forwarding table; the access gateway querying whether a destination MAC address of the data packet is in a MAC forwarding table of a terminal that is registered, and if yes, performing transmission optimization based on a channel situation of the terminal: for an IP channel, performing transparent transmission, for a QAM channel, performing MPE / TS encapsulation, and for other channels, performing corresponding processing based the channel situation of the terminal; otherwise, the access gateway continuing to query whether the destination MAC of the data packet is in a MAC forwarding table of a terminal that is not registered, and if yes, the access gateway forwarding the data packet to a corresponding port based on a corresponding MAC forwarding table entry in the MAC forwarding table of the terminal that is not registered; otherwise, the access gateway broadcasting the data packet to all other ports except a port that receives the data packet.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for forwarding and processing data messages in an access gateway. Background technique [0002] In a traditional network, there are two ways to establish a MAC forwarding table on an Ethernet: the first is to establish a dynamic MAC forwarding table through flooding, and the second is to manually configure a static MAC forwarding table. Among them, the dynamic MAC forwarding table established by means of flooding is generally used in a local area network, and if it is applied to a large-scale network, it will easily cause a broadcast storm in the network. Manually configured static MAC forwarding tables are used in carrier-class networks. Although it avoids broadcast storms in the network, because it uses manual establishment of static MAC forwarding tables and closes the MAC self-learning function, the number of MAC forwarding tables that need to be stored...
