Document Type and Number:
Japanese Patent JPH10173708
Kind Code:

Abstract:

To relieve the processing load of an access server with respect to the simple routing system in the access server that contains a plurality of terminals via a point-to-point (PPP) protocol and is connected to a router of a remote LAN via a WAN line.

An access server 3 is provided with a means 30, that converts a protocol identifier and a conversion table 31 that stores protocol identifiers in a protocol of a WAN line corresponding to each protocol identifier of a PDU of a PPP protocol. The access server 3 detects a protocol identifier of a corresponding WAN line 4 from the conversion table 31 by using the protocol identifier of a received PPP frame, without referring to information such as a network address in a PDU of the PPP frame received from a PPP line 2 and uses the detected protocol identifier (PID) to convert the PID of the PPP frame and processes the PDU into a capsule with the frame of the WAN line 4 as it is and transfers the result to a router 5.
