BACKGROUND

The communications industry is rapidly changing to adjust to emerging technologies and ever increasing cus tomer demand. This customer demand for new applications and increased performance of existing applications is driv ing communications network and system providers to employ networks and systems having greater speed and capacity (eg, greater bandwidth). In trying to achieve these goals, a common approach taken by many communications providers is to use packet Switching technology. Reliably and efficiently communicating information in a network is important. Different techniques may be employed in a network to communicate information in a network when the topology of the network changes and/or when commu nications resources become available.
