state of conferencing today
State of Conferencing Today
  • User-to-user solutions are limited
    • Difficult to schedule conferences and locate other users
    • Meeting scheduler can’t leave meeting
    • Only 2 video clients at a time
    • No bandwidth management
  • Server solutions fall short
    • Users have to know network topology
    • No bandwidth management, load balancing, or failover
    • H.323 video software doesn’t scale well

Components

CMS– Conference Management Service

coordinates and manages conferencing technologies and resources, and tracks and controls access to conferences.

Conference Technology Provider

Data Conferencing Provider-

Data Conferencing Provider is a conferencing technology based on the T.120 protocol stack that provides collaboration tools such as those found in Microsoft NetMeeting®. Data Conferencing Provider provides a T.120 multipoint control unit for data conferencing clients.

slide4

Video Conferencing Provider–

Video Conferencing Provider is a conferencing technology that provides video and audio conferences over multicast-enabled IP networks. Video Conferencing Provider also provides an H.323 bridge that allows H.323 conferencing clients to participate in audio and video conferences.

T.120 multipoint control unit (MCU) –

The T.120 MCU service runs as a component of Data Conferencing Provider and provides network connections between participants in a data conference.

Multicast Address Dynamic Client Allocation Protocol (MADCAP) –

Configure the DHCP server to provide Multicast addresses.

slide5

Conference calendar mailbox –

A conference calendar mailbox is an Exchange 2000 mailbox that stores the definitions and structure of all conferences

Conference resources –

Conference resources are Exchange 2000 mailboxes that conferencing clients invite when scheduling an online meeting. The conference properties, including the resource used, are stored in the conference calendar mailbox.

slide6

H.323 bridge –

The H.323 bridge permits NetMeeting clients that are unable to connect directly to multicast conferences to connect through a H.323 unicast session.

Codec –

A codec (coder/decoder) is any technology for encoding and decoding data.

More ECS Scalability
  • Uses Multicast IP Technology
    • What is multicast?
      • Many hosts sharing single IP to act as one host
      • Unicast data is sent based on number of participants
      • Multicast data is sent ONCE
    • Greatly enhances Video/Audio performance while reducing bandwidth usage

scheduling conferences
Scheduling Conferences
  • Scheduling a meeting (Outlook 2000)
    • Open Outlook 2000 and select “this is an online meeting using”…drop down to Exchange Conferencing Server
    • Check free/busy for the virtual meeting room (“conference resource”)
    • If available, Exchange adds conference resource to invitation
    • When user sends invitation, resource is reserved and URL for conference is included in invitations
  • Joining a meeting
    • When meeting reminder pops up, click on “join meeting” button
    • Browser pulls up Web page with conf info, embedded NM control, and multi-party video
what if no outlook 2000
What if no Outlook 2000?
  • Scheduling a meeting
    • Applications such as Outlook Web Access, previous versions of Outlook, Exchange 5.0 client, send meeting request to conference resource
    • If conference resource is available, Exchange sends email acknowledgement accepting reservation and providing conference URL
  • Joining a meeting
    • When meeting reminder pops up, click on “join meeting” button
    • Browser pulls up best possible client interface (depends on browser, OS, and version of NM)
    • If no meeting reminder, click on URL from email and browser will pull up best possible client

deployment considerations
Deployment Considerations
  • Exchange 2000 Conferencing Server requires one Windows 2000 and Exchange 2000 Server
  • Customers can run a mixed NT4/Exchange 5.5 and Win2K/Exchange 2K environment
  • CMS server can support thousands of users and should be centralized
  • Data MCUs and H.323 bridges should be deployed based on conferencing demand
cms placing
CMS Placing
  • Only 1 active CMS per Windows 2000 site
  • May or may not have CMS on each site
    • How many users conferencing on each site?
    • What is the purpose of the site?
    • Do you have multicast connectivity between sites?
  • Should setup separate site for Internet conferencing
  • Place CMS on separate box than Exchange and DHCP server

Tip: The Video Conferencing Service will not function properly if installed on same box as your active DHCP server. Therefore, place CMS on separate box if you plan on video conferencing.

mcu placement
MCU Placement
  • Wherever you have lots of users
    • Users usually connect to closest MCU
  • On subnets
    • How much traffic is acceptable?
  • On sites
  • At both ends of a slow link
  • Setup Internet focused MCU

fully functional conferencing
Fully Functional Conferencing:
  • Windows 2000 on all ECS Servers (CMS and MCUs)
  • Network multicast capable
    • Windows 2000 on clients
    • Multicast enabled routers
  • Exchange 2000 in domain
  • Certificate Server
  • Clients must have:
    • Windows 2000
    • Outlook 2000
    • ActiveX® and Java™ capable browsers
    • NetMeeting® 3.1
    • Audio/Video equipped
or configure down
Or, Configure Down
  • For non-Outlook 2000 users
    • Scheduling conf. takes a few more steps
  • For non-Windows 2000 clients
    • Multicast not available
    • Must enable H.323 bridge = reduced video
  • For Exchange 5.5 users
    • 2-way AD connector to replicate to 5.5
  • To check your routers
    • Use multicast diagnostics tool in Windows 2000 ResKit
cms service
CMS Service
  • Have a backup CMS server in the site
  • Create your Calendar Mailbox and resources in a separate MDB for fast backup/restore
  • Make sure your Calendar Mailbox server has fast connection with CMS
  • Create a separate conferencing site accessible from the Internet
t 120 mcu servers
T.120 MCU Servers
  • Always have MCUs on both sides of a slow link
  • Putting MCUs in specific subnets and assigning visibility restrictions is a tradeoff between performance and reliability
madcap servers
MADCAP Servers
  • Have backup MADCAP servers
  • Split scopes between two or more servers
  • Configure video resources to request addresses from all the MADCAPs with the same class of scope
conference resources
Conference Resources
  • Naming:
    • Distinguish from physical rooms, e.g. “Virtual Meeting Room (10)”
    • Indicate site, e.g. “Redmond Virtual Videoconference (5)”
    • Create several resources of each type with different sizes
    • You may name resources according to scenarios, e.g. “Corporate broadcast resource”
    • Create audio-only resource if video is not important and bandwidth is limited
priorities for next ecs
Priorities for “next” ECS
  • Conference recording
  • Unified client for ad-hoc and scheduled conferences
  • Integration of Presence/Instant Messaging (groups of IM users)
  • Broader B-to-B conferencing capabilities
  • Better integration with Windows Media Technology
