• Provider/Provider
• Client/Client
• Interconnection Architectures
• VoIP Peering is not dependent on traditional
  Network Peering Points for IP Traffic
• Currency of Interconnection

• Trusted vs. Best Efforts
• Session based Accounting
• Application based Peering
• Flow based Routing

Service Oriented Architecture SOA

• As the emergence of SOA impacts applications
  demand for QoS and new settlement methods will
  drive the economics of peering
• Session Boarder Controllers as a statefull
  level of service will always be expensive
• Flow based routing and MPLS Core networks will
  lead to a more scaleable Peering economy

5
Session Border Controller

• The SBC allows for an Application Based peering
  agreement to take place
• The SBC allows for better accounting and security
  within the Trusted network
• State-full packet inspection is expensive and
  will tend to stay at the edge of Trusted
  networks
