H.323 endpoints and the gatekeeper.

RISC

Reduced Instruction Set Computing

Router

On the Internet, a router is a device or, in some cases, software in a

computer, that determines the next network point to which a packet

should be forwarded toward its destination. The router is connected to

at least two networks and decides which way to send each information

packet based on its current understanding of the state of the networks

it is connected to. A router is often called as “gateway”. Compare with:

gateway. Refer to: relay.

RS-232

Most common Physical Layer interface. Known as EIA/TIA-232.

RTCP

Real-time Control Protocol (RTCP) is a companion protocol of RTP that is

used to maintain quality of service. Refer to: RTP(Real-Time Transport

Protocol).

RTP

1. Routing Table Protocol, VINES routing protocol based on RIP.

Distributes network topology, and aids VINES servers in finding

neighboring clients, servers, and routers. Uses delay as a routing metric.

Refer to: SRTP.

2. Rapid Transport Protocol. Provides pacing and error recovery for

APPN data as it crosses the APPN network. With RTP, error recovery and

flow control are done end-to-end rather than at every node. RTP

prevents congestion rather than reacts to it.

3. Real-Time Transport Protocol. Commonly used with IP networks. RTP is

designed to provide end-to-end network transport functions for

applications transmitting real-time data, such as audio, video, or

simulation data, over multicast or unicast network services. RTP provides

such services as payload type identification, sequence numbering,

time-stamping, and delivery monitoring to real-time applications.

SIP

The Session Initiation Protocol (SIP) is an application-layer control

(signaling) protocol for creating, modifying and terminating sessions

with one or more participants. These sessions include Internet

multimedia conferences, Internet telephone calls and multimedia

distribution. It is independent of sub packet protocols such as TCP,

UDP, ATM, X.25.

SmartViewer

The real-time monitoring, statistical data search and management GUI

based software developed by AddPac Technology for AP-GK1000, AP-

GK2000, AP-GK3000 models.

SNMP

Simple Network Management Protocol. Network management

protocol used almost exclusively in TCP/IP networks. SNMP provides a

means to monitor and control network devices, and to manage

configurations, statistics collection, performance, and security. Refer to:

SGMP, SNMP2.
