ABSTRACT:
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 3.4×1038packets.
