What Is NetMeeting?
NetMeeting enables you to communicate with others
over the Internet or your local intranet. Using
NetMeeting you can
  • Use data conferencing tools between an unlimited
    number of participants
  • Use audio and video between two people
  • Share and collaborate on applications
  • Use tools such as chat, whiteboard, and file
    transfer
  • Control the desktop remotely

4
NetMeeting Technology
  • Microsoft NetMeeting is a VoIP and multi-point
    videoconferencing client included in many
    versions of Microsoft Windows (from Windows 95
    OSR2 to Windows XP). It uses the H.323 protocol
    for video and audio conferencing, and is
    interoperable with OpenH323-based. It also uses
    a slightly modified version of the ITU T.120
    Protocol for whiteboarding, application sharing,
    desktop sharing, remote desktop sharing (RDS) and
    file transfers. The secondary Whiteboard in
    NetMeeting 2.1 and later utilizes the H.324
    protocol.

5
NetMeeting Technology
  • NetMeeting is a software application for audio
    and video conferencing. NetMeeting offers sharing
    of desktop video, audio, chat and file transfer
    functionality.
  • NetMeeting supports directory servers and
    services. NetMeeting uses may automatically
    register with a directory when they start their
    NetMeeting client. The directory then allows
    users to find online users by name or location.
    If no directory is available, NetMeeting users
    can also call each other directly by computer
    name or IP address.
  • Once connected to other users, NetMeeting places
    all parties in a "call." NetMeeting tracks the
    call roster and allows users to share their
    desktop windows, to chat, transfer files, or
    share a VoIP feed.

6
Voice Over Internet Protocol
  • VoIP is a technology that allows telephone calls
    to be made over computer networks like the
    Internet. VoIP converts analog voice signals into
    digital data packets and supports real-time,
    two-way transmission of conversations using
    Internet Protocol (IP).

7
Voice Over Internet Protocol
  • VoIP calls can be made on the Internet using a
    VoIP service provider and standard computer audio
    systems. Alternatively, some service providers
    support VoIP through ordinary telephones that use
    special adapters to connect to a home computer
    network. Many VoIP implementations are based on
    the H.323 technology standard.

8
Voice Over Internet Protocol
  • VoIP offers a substantial cost savings over
    traditional long distance telephone calls. The
    main disadvantage of VoIP is, like cell phones, a
    greater potential for dropped calls and generally
    lesser voice quality.

9
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 standards.

10
H.323 Protocol
  • Most voice over IP (VoIP) applications utilize
    H.323. 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.

11
OpenH323 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.

12
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 WebEx's MeetingCenter,
    Microsoft NetMeeting and Lotus Sametime to
    support application sharing, real-time text
    conferencing and other functions.

13
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.
  • The average person on the Internet works in a
    predominately TCP/IP environment. Web browsers,
    for example, use TCP/IP to communicate with Web
    servers.

14
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.

29
How to establish a connection through a firewall
  • When you use NetMeeting to establish a connection
    over the Internet, NetMeeting uses several IP
    ports to communicate with other meeting
    participants.
  • NetMeeting uses the following Internet Protocol
    (IP) ports
  • Port Purpose
  • -------------------------------------
  • 389 Internet Locator Server
    Transmission Control Protocol (TCP)
  • 522 User Location Server (TCP)

  • Dynamic H.323 call control (TCP)
  • Dynamic H.323 streaming Realtime Transport
    Protocol (RTP) over User Datagram Protocol
    (UDP)

30
How to establish a connection through a firewall
  • To establish outbound NetMeeting connections
    through a firewall, the firewall must be
    configured to do the following
  • Pass through primary TCP connections on ports
    522, 389, 1503, 1720 and 1731
  • Pass through secondary UDP connections on
    dynamically assigned ports (1024-65535).

31
How to make a video call with Net Meeting
  • To receive video, all of the following conditions
    must exist
  • There must be a user capable of sending video.
  • The user capable of sending video must be sending
    video to you.
  • If you are receiving the video, the status in the
    video window should read "Receiving." If the
    status reads "Paused," you will not receive live
    video until you click the Play button to resume
    play.

32
How to make a video call with Net Meeting
  • To send video, all of the following conditions
    must exist
  • You must have appropriate video hardware that is
    compatible with NetMeeting a camera or a video
    capture board.
  • The user sending the video should see the
    "Sending" status in the My Video window. Video is
    not sent if the status is "Paused."

33
How to make a video call with Net Meeting
  • Making an Audio and Video Connection
  • NetMeeting establishes a video connection
    automatically at the beginning of the call if the
    Automatically send video at the start of each
    call check box is selected.
  • If you are in a data conference and do not have
    an audio and video connection established, you
    can right-click a user on the Current Call tab,
    and then click Switch Audio And Video.
  • You can also click Switch on the toolbar, and
    then click to select the user with whom you want
    to establish an audio and video connection. Note
    that the Switch button is available only when the
    Current Call tab is selected.

34
How to Share programs in Net Meeting
  • NetMeeting allows you to share programs running
    on your computer with other NetMeeting
    participants. Programs can be shared even when a
    participant does not have that program installed
    on his or her computer.
  • When you are in a NetMeeting conference, others
    in the conference can see and use a program
    running on your computer.

35
How to Share programs in Net Meeting
  • To share a program within NetMeeting, click the
    Tools menu, point to Share Applications, and then
    click the program to share. Or, you can click the
    NetMeeting icon on the taskbar, point to Share
    Application, and then click the program you want
    to share. Or, you can click the Share button on
    the toolbar displayed for the current call.
  • When you select a program, it is seen on every
    other computer in the conference. The name of the
    program's owner is displayed in the upper- right
    corner of the window (if that window is not
    maximized).
  • By default, you are in control of the program.
    You can click Collaborate on the Tools menu, or
    click the Collaborate button on the toolbar for
    the current call, to allow others to use the
    program. In this mode, the initials of the
    participant who has control are added to the
    mouse pointer. Any user can change or run your
    program after taking control of the program by
    double-clicking the shared program.

36
How to Share programs in Net Meeting
  • Program sharing is achieved by passing graphics,
    mouse movements, and keyboard inputs to the other
    computers in real time. Your color and resolution
    settings have an impact on how items are
    displayed on other computers. If the originator
    of the shared program is using 1024 x 768 screen
    resolution, but a participant is using 640 x 480
    resolution, the participant's screen will be too
    small to display the whole window.

37
How to transfer files in Net Meeting
  • When you are in a NetMeeting conference, you can
    transfer a copy of a file to every participant in
    the conference.
  • You can transfer a file by dragging the file's
    icon to the NetMeeting window for global file
    transfers (transfers to all conference members),
    or by pointing to a single participant. To
    initiate a global file transfer, you can also
    click File Transfer/Send File on the Tools menu.
  • You can initiate individual file transfers by
    right-clicking a participant in the roster and
    then clicking Send File. In most cases, you see
    the Browse dialog box. If you use the drag
    method, no dialog box is visible.

38
How to use chat in Microsoft Net Meeting
  • NetMeeting includes a Chat tool that allows
    online meeting participants to communicate with
    each other using standard text messages. Chat is
    particularly useful when one or more meeting
    participants is unable to use the audio features
    of NetMeeting.
  • To start Chat, click Chat on the Tools menu in
    NetMeeting, click the Chat button on the toolbar,
    or click the Chat icon on the menu from the
    NetMeeting icon on the taskbar.

39
How to use chat in Microsoft Net Meeting
  • Chat includes the following features
  • When one person in a meeting runs Chat, it
    appears on all screens. Everyone in the meeting
    can then type messages simultaneously and see
    what other people are typing.
  • You can specify the font and font size, style,
    and effects that are used for the messages and
    information display in the Chat window on your
    computer.
  • You can specify the items included in the
    information display associated with each message
    in the Chat window and the format used for the
    messages.
  • You can save the current contents of the Chat
    window so they can be opened in NetMeeting,
    Microsoft Excel, or another spreadsheet or word
    processing program in the future.

43
Where is NetMeeting going today?
  • NetMeeting helped pioneer online conferencing
    when it was released in May 1996, before the
    advent of instant messaging (IM) and other
    services for real-time online communication.
  • The software still ships as part of Windows and
    some of its features, such as whiteboarding and
    application-sharing, are used by the MSN
    Messenger and Windows Messenger IM applications.

44
Future of NetMeeting
  • NetMeeting is no longer included with Windows
    Vista, and has been replaced by Windows Meeting
    Space and Microsoft office Live Meeting.
  • However, a hot fix for Vista was published by
    Microsoft on March 22, 2007.
  • The hot fix contains an installer package to
    install NetMeeting 3.02 on Windows Vista
    business, enterprise or ultimate versions.
    Version 3.02 is essentially a port of 3.01 to
    Vista. Net meeting doesn't work with Vista Home
    edition.

45
Future of NetMeeting
  • NetMeeting can still be installed and run on
    Windows Vista. A hotfix for Vista was published
    by Microsoft on March 22, 2007 can obtain this
    hotfix by contacting Microsoft Support. The
    hotfix contains an installer package to install
    NetMeeting 3.02 on Windows Vista business,
    enterprise or ultimate versions. Version 3.02 is
    essentially a port of 3.01 to Vista. Netmeeting
    doesn't work with Vista Home edition.

46
Future of NetMeeting
  • Microsoft plans to phase NetMeeting out and
    remove it from its Web site. The NetMeeting
    directory is already gone, which means that users
    have to type in the IP address of the person they
    want to conference with or use another online
    directory service. There is no time-frame for
    the NetMeeting phase-out. It appears that it
    will be a gradual transition.
  • Many businesses still use NetMeeting, although
    IM and Web conferencing products outclass it in
    terms of usability, analysts said.

47
Future of NetMeeting
  • Before video service became common on free IM
    clients, such as Yahoo! Messenger and MSN
    Messenger, NetMeeting was a popular way to
    perform videoconferences and chatting over the
    Internet (with the help of public ILS servers, or
    "direct-dialing" to an IP address).
  • Since the release of Windows XP, Microsoft has
    deprecated it in favor of Windows Messenger and
    Microsoft Office Live Meeting, although it is
    still installed by default (Start Run...
    C\Program Files\NetMeeting\conf.exe). Note that
    Windows Messenger, MSN Messenger and Windows Live
    Messenger hooks directly into NetMeeting for the
    application sharing, desktop sharing, and
    Whiteboard features exposed by each application.
