Abstract

Compensating for time stamp aging in systems employing fair packet queuing algorithms by (i) representing a time stamp of each head-of-line packet of a session with a finite number of bits, (ii) representing a system potential with a finite number of bits, (iii) storing a packet's time stamp when it is served, (iv) storing an obsolete indicator for each stored time stamp, and (v) updating the obsolete indicator or purging obsolete time stamps.
