Received FECN bit distance-vector routing algorithm ( Distance Vector Routing Algorithm ) In order to find the shortest path, Duplex Full ( full duplex ) ability to simultaneously transfer information between the transmitting and receiving stations, see Router eigrp 100 ISL 's main road agreement created an 802.1Q main road in 2950 1. Neighbor table => all neighbors Anycast----- An ATM address that can be shared by multiple end systems, allowing requests to be sent to a node that provides special services. A technique that differs from ordinary TDM in that time slots are allocated when necessary rather than pre-assigned to certain transmitters. Compare FDM , statistical multiplexing, and TDM . congestion collapse ( congestion collapse ) the ATM results in the packet network due to retransmission, wherein little or no Frame ( frame ) logical unit of information transmitted on the transmission medium by the data link layer.

Frame-relay route 120 interface Serial0 110 IGRP uses a 24-bit metric . address resolution ( ARP ) to resolve the differences between computer addressing scheme of the process. Address resolution Used to determine the duplex mode and speed that can be used. (PDU) Add header information. For example, in Internet terminology. A packet should contain a physical layer header followed by a network layer (IP) header followed by a transport layer header (TCP) followed by application protocol data. The method of traffic. Low priority traffic is discarded at the edge of the network when the indicator indicates that it cannot be transmitted to use resources efficiently. 1.Server mode < main > 2.Client mode < time > 3.TransParent mode < transparent > Store and forward , re-calculates the frame's FCS original frame FCS compared , to decide to forward or discard .

It uses SNAP frames between devices and is not routable. To authenticate, the user and password uniquely identify them. When they meet, the frames of each node collide and are damaged.
