A method and apparatus for providing call admission control in a packet network such as an internet protocol (IP) network are provided. More particularly, a terminating endpoint of a logical connection on a packet network, e.g. an IP network, is provided with the ability to make a decision on whether to accept or reject an incoming call based on quality of service (QoS) indicator based on QoS metrics. These metrics indicate quality of service levels for specific logical connections and are accumulated over specified time periods.

An apparatus and method for providing a back out routine for a failed programmable hardware update is provided. In one embodiment, the method includes: a) storing a new software image for the programmable device associated with the hardware update, b) storing a previous software image for the programmable device, c) programming the programmable device to operate according to the new software image, d) determining if there is a failure associated with the programming step, and e) if a failure is identified, programming the programmable device to operate according to the previous software image, otherwise the hardware update to the programmable device was successful. In one aspect, the back out routine is provided for a program load failure. In another aspect, the back out routine is provided for a programmable device failure.

Back out provision for failed programmable hardware update

An arrangement and method for switching a single destination data channel to a different destination without losing any data messages. Such a switch is required, for example, when a switch is made to a standby control unit and the messages originally destined for the original active control unit must be sent to the standby. Received messages are drained from the source prior to making the switch. Appropriate data is copied from the active unit to the standby so that the standby unit is in a state to start accepting newly queued messages from the source.
