Document Summary

With abr, the transfer characteristics provided by the network can change subsequent to connection establishment. A flow-control mechanism offers several types of feedback to control the source rate in response to changing atm-layer conditions. This feedback is conveyed to the source through control cells called resource management (rm) cells. The abr service does not require bounding the delay or the delay variation experienced by a given connection. Abr service is not intended to support real-time applications. On the establishment of an abr connection, an end system specifies to the network both a maximum required bandwidth and a minimum usable bandwidth. These are designated as the peak cell rate (pcr) and the minimum cell rate (mcr), respectively. List kept by a router or firewall to control access to or from the router for several services (for example, to prevent packets with a certain ip address from leaving a particular interface on the router).
