PVC. Permanent Virtual Circuit. PVCs save bandwidth associated with circuit
establishment and tear down in situations where certain virtual circuits must
exist all the time.

Router. Network layer device that uses one or more metrics to determine the
optimal path to forward network traffic. Routers forward packets from one
network to another based on network layer information. a router may connect
networks using various protocols by encapsulating data within another
network's packet format or by removing layers of packet formatting.

SNMP. Simple Network Management Protocol. Network management
protocol used in TCP/IP networks. SNMP provides a way to monitor and
control network devices and to manage configurations, Statistics collection,
performance and security.
