13th July 2004 Videoconferencing Project
Northern Grid Proposal
Videoconferencing in Schools
13th July 2004 Videoconferencing Project
Requirement
• Multipoint Conferencing
• Intra-Northern Grid Conferencing
• Inter-RBC Conferencing
• External IP Conferencing
• UKERNA Gateway Conferencing
13th July 2004 Videoconferencing Project
Solution Manufacturers
• Polycom – Service Providers choice for MCU solutions in an ISDN environment.
• Cisco – OEM Radvision products• Radvision – Recognised as strongest IP solution
provider.
H.323 stack designed by Radvision and used by Polycom, Tandberg, Sony, Cisco, Aethra and many more. Radvision Gatekeepers offer end to end network control
13th July 2004 Videoconferencing Project
• Where to site solution?
•Middlesbrough PoP
•Firewall DMZ
•Redundancy of PoP
•No PoP, No Network, No Videoconferences
13th July 2004 Videoconferencing Project
Solution Components
• Gatekeeper/Alternate Gatekeeper• Multipoint Control Unit (MCU)• Multimedia Video Processors• Video Communication Scheduler• Data Collaboration Server• Network Management Application• Servers for Gatekeepers & Applications• Distributed Architecture
13th July 2004 Videoconferencing Project
The Core Gatekeeper
• Radvision ECS100 Pro with Firewall Traversal• 500 Registrations
• 100 Concurrent Inter LEA Calls
• Hierarchy with UKERNA
• Neighbours with LEA Gatekeepers
• Neighbours with other RBC Gatekeepers• Routes call traffic through network• Requires server
• H.323 Proxy built in
13th July 2004 Videoconferencing Project
The Alternate Gatekeeper
• ECS100 Pro Alternate
• Communicates with Core Gatekeeper every 3 seconds
• Assumes Core Gatekeeper function and identity if core Gatekeeper fails
• Requires server
13th July 2004 Videoconferencing Project
Gatekeeper Architecture
13th July 2004 Videoconferencing Project
•If LEA has Gatekeeper then all Intra-LEA traffic stays within LEA
•All Inter-LEA and Inter-RBC traffic is routed through the Northern Grid Core Gatekeeper
•Easynet provide routing for Videoconferences to UKERNA on Interconnect and off-net through Internet.
