User-Network Signaling

• User-Network Signaling is a mechanism between the user and the network through which they:

  • exchange control of information
  • request the use of network resources
  • negotiate circuit parameters

• The VPI/VCI pair as well as the requested bandwidth and quality of service are allocated to a virtual circuit as a result of a successful signaling exchange

• User-network signaling protocols support the opening and closing of connections

• These signaling protocols are run on the Signaling ATM Adaptation Layer (SAAL)
