Abstract
Methods and apparatus are provided for performing traffic admission control in a Differentiated Services (DiffServ) network environment. According to one embodiment, a predetermined portion of available bandwidth between a first network device and a second network device is reserved as a real-time bandwidth pool for real-time communication sessions among users of a first group of terminals associated with the first network device and a second group of terminals associated with the second network device, the real-time bandwidth pool corresponding to estimated bandwidth remaining available on a path through a Differentiated Services (DiffServ) network interposed between the first group of terminals and the second group of terminals. Thereafter, the real-time bandwidth pool is shared among multiple real-time communication sessions involving terminals of the first and second groups of terminals by selectively admitting application sessions based upon currently available resources in the real-time bandwidth pool.
