transmission quality and service availability) of a transmission system.
Stands for Random-Access Memory. RAM is a volatile memory that can be read or written
by a microprocessor.
RAS refers to a protocol for registration, connect acknowledgement, and status protocol.
RAS is used for H.323 to find or have a conversation with a gateway.
Stands for Reduced Instruction Set Computing.
This is a network layer device that determines the optional route to which network traffic is
delivered by using one or more metrics. A router forwards packets from a network to
another network based on the network layer information. A router is sometimes called a
gateway. (A gateway in this meaning is getting older.) Compare to: Gateway; Reference:
Relay
This is a frequently used physical layer interface, and is known as EIA/TIA-232 nowadays.
Stands for RTP Control Protocol. This protocol monitors the QoS of IPv6 RTP connections,
and transfers data on sessions in operation. Reference: Real-Time Transport Protocol (RTP)
1. Stands for Routing Table Protocol. This VINES routing protocol based on RIP distributes
network topology data, and helps the VINES server that searches for adjoining clients,
servers, and routers. A delay time is used as a routing metric. Reference: SRTP
2. Stands for Rapid Transport Protocol. RTP provides facing and error recovery services to
the APPN data when the data passes the APPN network. RTP allows you to check error
recovery and flow control synthetically. RTP does not recover but prevents traffic
congestion.
3. Stands for Real-Time Transport Protocol. This is one of the IPv6 protocols. RTP is
designed to enable the synthetic network transmission feature in the application that
transfers real-time data such as audio, video, and simulation data through multicast or
unicast network services. RTP enables the real-time application to identify a payload type,
specify a sequence number, perform time-stamping, and to monitor a transmission
procedure.
Stands for Session Initiation Protocol. SIP is an application layer control protocol based on
very simple texts, and allows more than one user to make, correct, or complete a session.
Examples of sessions include remote conferences, phones, meetings, event notifications,
and instant messaging on the Internet. SIP is independent to lower-level packet protocols
(e.g. TCP, UDP, ATM, and X.25).
This is software that allows you to monitor AP-GK1000, AP-GK2000, and AP-GK3000,
which are the gatekeeper series of AddPac Technology, in a Graphical User Environment
