- The level of privilege afforded, or level of restriction imposed upon, a system user. Each key system (KTS), PBX, or Centrex user is assigned a CoS that defines that individual's level of access privileges to internal and network resources, with examples being feature assignments and priority levels for access to circuits. See also Centrex, KTS, and PBX.
- A priority level assigned to a particular traffic type in a packet data network. Real-time, uncompressed voice and video traffic, for example, typically are assigned the highest priority level, as they are not tolerant of latency and loss. E-mail and certain types of signaling and control messages typically are assigned the lowest priority level, as they are highly tolerant of latency and loss. CoS is a highly effective means of managing traffic on a best effort basis, but does not offer the performance assurances or guarantees of a Quality of Service (QoS) mechanism. As examples, CoS mechanisms are employed in local area networks (LANs), frame relay networks, Internet Protocol (IP) networks, and Multiprotocol Label Switching (MPLS) networks. QoS mechanisms are employed in networks based on asynchronous transfer mode (ATM). See also ATM, Frame Relay, IP, latency, and QoS.
