ABSTRACT:
In a multilink point-to-point protocol (PPP) network access server, a method is provided in one aspect of the invention allocating ports among various users that includes allocating primary ports among various users, and thereafter, allocating secondary ports among various users only until the number of allocated secondary ports reaches a prescribed maximum.Another aspect of the invention may be thought of as a back-channel allocation method that includes determining whether a back channel is actually being used by a first network client, and if not then allocating the unused back channel to a second network client. In a final aspect of the invention an auxiliary channel resource allocation apparatus for use with a multilink PPP access server, is provided that includes decision or detection logic determining the availability of an auxiliary channel resource previously allocated to a first user of the access server, the decision logic signaling such availability, and allocation or reallocation logic responsive to the signaling to allocate the available auxiliary channel resource to a second user of the access server. The foregoing and other objects, features and advantages of the invention will become more readily apparent from the following detailed description of a preferred embodiment which proceeds with reference to the drawings.
