Net. Meeting Technology • Microsoft Net. Meeting is a Vo. IP and multi-point videoconferencing client included in many versions of Microsoft Windows (from Windows 95 OSR 2 to Windows XP). It uses the H. 323 protocol for video and audio conferencing, and is interoperable with Open. H 323 -based. It also uses Open. H 323 a slightly modified version of the ITU T. 120 Protocol for whiteboarding, whiteboarding application sharing, sharing desktop sharing, sharing remote desktop sharing (RDS) and file transfers. The secondary Whiteboard in Net. Meeting 2. 1 and later utilizes the H. 324 protocol.

Net. Meeting Technology • • • Net. Meeting is a software application for audio and video conferencing. Net. Meeting offers sharing of desktop video, audio, chat and file transfer functionality. Net. Meeting supports directory servers and services. Net. Meeting uses may automatically register with a directory when they start their Net. Meeting client. The directory then allows users to find online users by name or location. If no directory is available, Net. Meeting users can also call each other directly by computer name or IP address Once connected to other users, Net. Meeting places all parties in a "call. " Net. Meeting tracks the call roster and allows users to share their desktop windows, to chat, transfer files, or share a Vo. IP feed.

Voice Over Internet Protocol • Vo. IP is a technology that allows telephone calls to be made over computer networks like the Internet. Vo. IP converts analog voice signals into digital data packets and supports real-time, two-way transmission of conversations using Internet Protocol (IP).

Voice Over Internet Protocol • Vo. IP calls can be made on the Internet using a Vo. IP service provider and standard computer audio systems. Alternatively, some service providers support Vo. IP through ordinary telephones that use special adapters to connect to a home computer network. Many Vo. IP implementations are based on the H. 323 technology standard.

Voice Over Internet Protocol • Vo. IP offers a substantial cost savings over traditional long distance telephone calls. The main disadvantage of Vo. IP is, like cell phones, a greater potential for dropped calls and generally lesser voice quality.

H. 323 Protocol • H. 323 is a protocol standard for multimedia communications. H. 323 was designed to support real-time transfer of audio and video data over packet networks like IP. The standard involves several different protocols covering specific aspects of Internet telephony. The International Telecommunication Union (ITU-T) maintains H. 323 and these related

H. 323 Protocol • Most voice over IP (Vo. IP) applications utilize H. 323 supports call setup, teardown and forwarding/transfer. Architectural elements of a H. 323 based system are Terminals, Multipoint Control Units (MCUs), Gateways, an optional Gatekeeper and Border Elements. Different functions of H. 323 run over either TCP or UDP.

Open. H 323 PROTOCOL • Full featured, open source implementation of the H. 323 Voice over IP protocol. The code is written in C++ and, through the development effort of numerous people around the world, fully supports the H. 323 protocol. The software has been integrated into a number of open source and commercial software products.

ITU T. 120 PROTOCOL • ITU-T recommendation that describes a series of communication and application protocols and services that provide support for real-time, multipoint data communications. It is used by products such as Cisco Web. Ex's Web. Ex Meeting. Center, Meeting. Center Microsoft Net. Meeting and Lotus Sametime to support application sharing, real-time text conferencing and other functions.

Transmission Control Protocol • Transmission Control Protocol (TCP) and Internet Protocol (IP) are two distinct network protocols, technically speaking. TCP and IP are so commonly used together, however, that TCP/IP has become standard terminology to refer to either or both of the protocols. • IP corresponds to the Network layer (Layer 3) in the OSI model, whereas TCP corresponds to the Transport layer (Layer 4) in OSI. In other words, the term TCP/IP refers to network communications where the TCP transport is used to deliver data across IP networks.

UDP Protocol • UDP is a lightweight transport built on top of IP. UDP squeezes extra performance from IP by not implementing some of the features a more heavyweight protocol like TCP offers. Specifically, UDP allows individual packets to be dropped (with no retries) and UDP packets to be received in a different order than they were sent.
