APPARATUS FOR FLOW CONTROL
First Claim
1. An apparatus for flow control which is located in a mobile router having a mobile network as a subordinate, comprising:
- one or a plurality of egress interfaces used for communication with a node existing in the exterior of said mobile network;
one or a plurality of ingress interfaces used for communication with a node connected to said mobile network;
a filter policy list storing a flow filter policy describing at least association between traffic of the node connected to said mobile network and identification information on said egress interface to be used for the traffic; and
matching means for, when a packet is transferred from the node connected to said mobile network, retrieving the flow filter policy of the node from said filter policy list to select the egress interface to be used for the transfer of the packet by referring to the retrieved flow filter policy.

Abstract
Disclosed is a technique which enables a mobile node (MN) connected to a mobile router (MR) to carry out flow filtering in a mobile network. This technique allows an MN 25 in a mobile network 24 to set a policy needed for the flow filtering in an MR 10 and, in the present invention, an MR inserts an egress characteristic thereof into, for example, a router advertisement message so that the egress characteristic, a node in a mobile network cannot grasp originally, can be advertised to the interior of the mobile network. Thus, the MN can grasp a characteristic of an access network (characteristic of access system 20) even in a case in which it is connected to the MR, which achieves intelligent flow filtering.

12. An apparatus for flow control which is located in a node connected to a mobile network under a mobile router, comprising:
-
characteristic information acquiring means for acquiring information indicative of a characteristic of an egress interface of said mobile router from said mobile router; flow filter policy generating means for generating a flow filter policy describing at least the association between traffic of the node and identification information on said egress interface of said mobile router to be used for the traffic on the basis of the information acquired by said characteristic information acquiring means; and flow filter policy transmitting means for transmitting the flow filter policy to said mobile router. - View Dependent Claims (13)
