Compressed Real-Time Transport Protocol (CRTP)
|
Protocol defined in RFC 2508 that compresses the size of IP,
UDP, and Real-Time Transport Protocol (RTP) headers and works with
reliable and fast point-to-point links for voice over IP (VoIP) traffic.
|
|
data-link connection identifier (DLCI)
|
Identifier for a Frame Relay virtual connection, also called
a logical interface.
|
|
link fragmentation and interleaving (LFI)
|
For MLFR with Frame Relay traffic or MLPPP with PPP traffic,
a method of reducing excessive delays by fragmenting long packets
into smaller packets and interleaving them with real-time frames.
For example, short delay-sensitive packets, such as those of packetized
voice, can race ahead of larger delay-insensitive packets, such as
common data packets.

|
link services
|
Capabilities on an interface that use Multilink Frame Relay
(MLFR) and Multilink Point-to-Point Protocol (MLPPP), link fragmentation
and interleaving (LFI), Compressed Real-Time Transport Protocol (CRTP),
and certain class-of-service (CoS) components to improve packet transmission,
especially for time-sensitive voice packets.
|
|
Multilink Frame Relay (MLFR)
|
Protocol that allows multiple Frame Relay links to be aggregated
by inverse multiplexing.
|
|
Multilink Point-to-Point Protocol (MLPPP)
|
Protocol that allows you to bundle multiple Point-to-Point Protocol
(PPP) links into a single logical unit. MLPPP improves bandwidth efficiency
and fault tolerance and reduces latency.
|
|
Point-to-Point Protocol (PPP)
|
Link-layer protocol defined in RFC 1661 that provides multiprotocol
encapsulation. PPP is used for link-layer and network-layer configuration.
|
|
shaping rate
|
In class of service (CoS) classification, a method of controlling
the maximum rate of traffic transmitted on an interface.
