A METHOD FOR ROUTING THE CONCOURSE SERVICE

摘要

The invention discloses a method for routing the concourse service, which configures a node which make it have multi access ports, one trunk port and an access/concourse group for achieving the character information fields of the character information value from the data packet; and according to the access/concourse group establishes an character information table which takes the character information value and the access port number as items. The method further comprises: in access/concourse group the access port that receives data packets, achieves the character information value corresponding to character information field from the data packet, and takes the character information value as index to search for the character information table; if it doesn't find a corresponding item, it establishes an item comprising the character information value and the access port number, then it transmits the data packet to the trunk port; if it finds a corresponding item, it transmits the data packet to the trunk port when its access port number and the access port number in the item are same; and when the above two number are not same it updates the access port number in the item with the access port number, then it transmits the data packet to the trunk port.
