Abstract: Methods and systems for performing admission control include receiving an indication of at least one service reliability target associated with at least one service and determining whether one of the at least one service reliability targets is met. If the one of the at least one service reliability targets is met, an initial context associated with the service is configured. The at least one service reliability targets may be received with an initial context setup request message and responded to with either an initial context setup failure message or an initial context setup response message.

Abstract: Fault management and recovery in a distributed network accounting system includes classifying nodes in the system according to complexity of processing in the node. For nodes of relatively low processing complexity, context check-pointing a state of processing in the nodes to permit automatic recovery of the node to the nodes' most recent processing context checkpoint; and for nodes of relatively high complexity, producing a directed graph of the programmable nodes that controls a flow of data and control of processing through the system, and producing a dynamic modification of the directed graph to automatically fail-over to redundant back-up nodes based on thresholds established for the component hosts.
