Abstract:
PROBLEM TO BE SOLVED: To provide a method, system, and program for a protocol for authenticating a port base to which an address is assigned dynamically within a network environment, specifically for authenticating a port base within a network environment where connection information is incorporated and stored. SOLUTION: In this method, supplicant information observed by an authentication switch is incorporated and forwarded to a central site, i. e. a manager site. This information is created mainly during protocol exchange and includes correlation between an owner and an IP address, MAC, IP, a port switch number, a switch ID, and an authentication server ID. This facilitates a manager access to the information created as the result of dynamic address assignment, authentication, and connection-related protocol exchange. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
A station in a communications network determines the mode (full-duplex or half-duplex) in which it communicates with a concentrator port by establishing a Registration routine between the station and the concentrator port. The station and concentrator port exchange frames which disclose the capabilities of the concentrator port. If the concentrator port has duplex capabilities, the station enters as a duplex station. Otherwise, the station enters in a half-duplex (token ring) mode.
