Collaborative Bandwidth on Demand (CollaBOD) Operational System for Bandwidth on Demand Advance Scheduling Collaborative Network Technologies Inc. March 2004
The Problem Providing multi-user control of bandwidth on demand facilities dispersed in a rural environment
The Challenge • Users book and operate their own services • Users are scattered across wide geography in several time zones • The shared network infrastructure must not become over-committed • The network is comprised of locations connected with limited capacity gateways • Terrestrial dedicated and dialup • Bandwidth on demand and dedicated satellite • Wired, wireless and hybrid local networks
The Considerations • Ease of operation • Ease of maintenance • Users must not interfere with concurrent programming • Existing programs may need to be overridden in case of disaster • Utilization reports are required for capacity planning and billing
The Solution CollaBoD was designed to manage bandwidth on demand in a distributed user environment. CollaBoD is deployed within Telesat Canada’s infrastructure supporting the SmartLabrador initiative
Network Architecture • Users access CollaBoD engine with the web and a java application • Engine accessible from internet via firewall • Engine holds JDBC database which logs session detail • Engine controls circuits in real time thru SNMP • CollaBOD model can be extended to other BOD satellite technologies
Stakeholder Organizations • Application service provider • End-user groups • Community facilities supplier • Integration and technical services • Supplier of third party central services (for example video bridge) • Satellite communications supplier • Terrestrial communications supplier
Human Roles in the Organizations • Central operation • Advance booking • Program operation • Reporting
Central Operations • The satellite provider’s network operations center can monitor existing and requested program bookings • Central operations can override programming to resolve conflicts over shared resources in real time • Central operations interact with program operators and technical support personnel
Advance Booking • The booking coordinator handles requests for scheduled services • The booking coordinator is the primary liasion with the end user group prior to the scheduled event • The CollaBoD engine is configured with a summary of the network infrastructure • The CollaBoD engine compares booking requests against scheduled programming and available capacity before confirming
Program Operators • Program operators interact with end users or community facilitators • Program operators perform real time monitoring of sessions • Operators can override for disaster recovery or emergency • Operators record the success and failure of sessions with annotation
Reporting • Billing and Utilization • Capacity Assessment • Customer Management
Case Study: Smart Labrador • Area over 100 000 square kilometers • 40 video conferencing rooms • 25 communities in 3 time zones • Always-on Internet • BoD and dedicated gateways with capacity for one video conference • Each gateway services several H.323 capable video rooms • Multipoint video conferencing hub
SmartLabrador Stakeholder Groups • Application coordinator (SmartLabrador) • Satellite provider (Telesat) • Telecommunications provider (Aliant) • Video bridge provider (TETRA) • End consumers of shared facilities • Health Labrador • Grenfell Regional Health Services • K12 and post-secondary distance education • Community development groups • Government agencies • Municipal Councils
In Conclusion • SmartLabrador and Telesat both derive value from the CollaBoD • On demand circuits are brought up and down without real time human intervention • Event coordination is simplified because conflicts are detected and rectified early
