virtual circuits การใช้

• On the other hand, permanent virtual circuits are preconfigured into the network.
• LMI virtual circuit status messages provide communication and synchronization between Frame Relay DCE devices.
• These virtual circuits carry variable-length packets.
• Tymnet II's different method of constructing virtual circuits allowed for much better scalability.
• The VPI is useful for reducing the switching table of some virtual circuits which have common paths.
• In " LLC Encapsulation " the hosts use a single virtual circuit for multiple protocols.
• A DLR may describe an end-to-end circuit that comprises physical or virtual circuits.
• Virtual circuits are especially useful in building robust failover mechanisms and allocating bandwidth for delay-sensitive applications.
• Multiple virtual circuits can be active on the same physical end-points ( performed by using subinterfaces ).
• In the case of ATM or Frame Relay based access, individual subscribers are identified by Virtual Circuit IDs.
• Connection-oriented communication may be a circuit switched connection, or a packet-mode virtual circuit connection.
• With virtual circuit multiplexing, the communicating hosts agree on the high-level protocol for a given circuit.
• Resorting to a virtual circuit transport, using the Transmission Control Protocol ( TCP ), would greatly increase overhead.
• A permanent virtual circuit ( PVC ) is a virtual circuit established for repeated / continuous use between the same clearing.
• A permanent virtual circuit ( PVC ) is a virtual circuit established for repeated / continuous use between the same clearing.
• Because most carriers charge for each virtual circuit, customers try to avoid using multiple circuits because it adds unnecessary cost.
• After data transmission is completed, the " connection termination " closes established virtual circuits and releases all allocated resources.
• X . 25 supports two types of virtual circuits, virtual calls ( VC ) and permanent virtual circuits ( PVC ).
• X . 25 supports two types of virtual circuits, virtual calls ( VC ) and permanent virtual circuits ( PVC ).
• Finally, ATM networks create and remove switched virtual circuits ( SVCs ) on demand when requested by an end piece of equipment.
