Collaborative Bandwidth on Demand Colla BOD Operational System

Collaborative Bandwidth on Demand (Colla. BOD) 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 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 Colla. Bo. D was designed to manage bandwidth on demand in a distributed user environment. Colla. Bo. D is deployed within Telesat Canada’s infrastructure supporting the Smart. Labrador initiative

Network Architecture • Users access Colla. Bo. D 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 • Colla. BOD 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 Colla. Bo. D engine is configured with a summary of the network infrastructure • The Colla. Bo. D engine compares booking requests against scheduled programming and available capacity before confirming

Advance Booking

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

Program Operators

Reporting • Billing and Utilization • Capacity Assessment • Customer Management

Sample Reports

Case Study: Smart Labrador • • • Area over 100 000 square kilometers 40 video conferencing rooms 25 communities in 3 time zones Always-on Internet Bo. D and dedicated gateways with capacity for one video conference • Each gateway services several H. 323 capable video rooms • Multipoint video conferencing hub

Smart. Labrador Stakeholder Groups • • • Application coordinator (Smart. Labrador) Satellite provider (Telesat) Telecommunications provider (Aliant) Video bridge provider (TETRA) End consumers of shared facilities – – – Health Labrador Grenfell Regional Health Services K 12 and post-secondary distance education Community development groups Government agencies Municipal Councils

In Conclusion • Smart. Labrador and Telesat both derive value from the Colla. Bo. D • On demand circuits are brought up and down without real time human intervention • Event coordination is simplified because conflicts are detected and rectified early
