Network Virtualisation –
A Service Provider’s Perspective

The Evolution of SOUL
• Australian broadcasters required a broadband network for
Digital TV (DTV)
• Buy or Build? Optus or Telstra were the only bandwidth resale
options … (both expensive)
• NBN therefore elected to build excess broadband capacity at
minimal marginal CapEx and OpEx
• A separate entity was created as a licensed carrier to facilitate
the sale of excess capacity, adopting the Soul Pattinson name
• Convergence of broadcast television and telecommunications
content and distribution successfully implemented across the
network
• The business and network expanded along eastern seaboard of
Australia
Who is SOUL?
• The largest operator of ‘greenfield’ MPLS based IP
networks in Australia
• The only national PSTN interconnected IP network in
Australia
• Voice, video and data over a single, national IP
network
• Fibre network throughout intercapital and regional
Australia
• In excess of 300 points of presence (PoPs)
Who is SOUL?
• Network has full QoS feature support with Service
Level Guarantees to support lower latency, packet
loss and jitter
• 100% Powered by Cisco Systems – Single vendor
platform
• Infrastructure is SOUL owned and operated, and
independent of Telstra
• In excess of 900 employees in offices throughout
Australia
• Consumer Call Centres in Perth and Sydney
Network Design
• The network was initially designed for DTV Transmission
• Provides higher availability than standard Telco networks, as
the network core cannot suffer any downtime
• Increased redundancy in all layers
• Architecturally different to other telco networks as design is
optimised for content delivery, not just traditional services
• This increases the access to regional areas due to distributed
core design
• Diverse fibre paths also operate across the country for
redundancy
• Capability exists to rapidly increase regional reach (new POI
deployments)
