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 Internet Engineering Task Force
(IETF) standard protocol for initiating an interactive user session that involves
multimedia elements such as video, voice, chat, gaming, and virtual reality.
Like HTTP or SMTP, SIP works in the Application layer of the Open Systems
Interconnection (OSI) communications model. The Application layer is the
level responsible for ensuring that communication is possible. SIP can
establish multimedia sessions or Internet telephony calls, and modify, or
terminate them. The protocol can also invite participants to unicast or multicast
sessions that do not necessarily involve the initiator. Because the SIP supports
name mapping and redirection services, it makes it possible for users to
initiate and receive communications and services from any location, and for
networks to identify the users whatever they are. SIP is a request-response
protocol, dealing with requests from clients and responses from servers.
Participants are identified by SIP URLs. Requests can be sent through any
transport protocol, such as UDP, SCTP, or TCP. SIP determines the end
system to be used for the session, the communication media and media
parameters, and the called party's desire to engage in the communication.
Once these are assured, SIP establishes call parameters at either end of the
communication, and handles call transfer and termination. The Session
Initiation Protocol is specified in IETF Request for Comments [RFC] 2543.
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
