A solution for matching RADIUS request packets with corresponding RADIUS response packets when the number of simultaneous outstanding requests is greater than 256 involves using a sixteen-octet authenticator field in each packet. For each response packet that arrives, the identifier of the packet is compared in turn with the identifier of each outstanding request packet. If the identifiers match, the authenticators are then compared. If the results of the comparison indicate a match, the packet is accepted and no further processing of the outstanding requests is required. Otherwise, a search of the outstanding request packets is continued. This solution allows for more than 256 simultaneous outstanding RADIUS requests and only encounters a mismatch or ambiguous match with a probability of one in 3.4×1038 packets.
A method for matching a RADIUS response packet with a corresponding RADIUS request packet from one or more RADIUS request packets, the packets all having identifier fields and authenticator fields, including:
A method for matching an access response packet with a corresponding access request packet from one or more access request packets, the packets all having identifier fields and authenticator fields, including:
A method for matching an accounting response packet with a corresponding accounting request packet from one or more accounting request packets, the packets all having identifier fields and authenticator fields, including:
An apparatus for matching a RADIUS response packet with a corresponding RADIUS request packet from one or more RADIUS request packets, the packets all having identifier fields and authenticator fields, the apparatus including:
An apparatus for matching an access response packet with a corresponding access request packet from one or more access request packets, the packets all having identifier fields and authenticator fields, the apparatus including:
An apparatus for matching an accounting response packet with a corresponding accounting request packet from one or more accounting request packets, the packets all having identifier fields and authenticator fields, the apparatus including:
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for matching a RADIUS response packet with a corresponding RADIUS request packet from one or more RADIUS request packets, the packets all having identifier fields and authenticator fields, the method including:
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for matching an access response packet with a corresponding access request packet from one or more access request packets, the packets all having identifier fields and authenticator fields, and a variable n initially set to 1, the method including:
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for matching an accounting response packet with a corresponding accounting request packet from one or more accounting request packets, the packets all having identifier fields and authenticator fields, the method including:
