This presentation discusses techniques and solutions to satisfy requirement for VPN’s that need to reside on different autonomous systems or Service providers in different geographic areas. In today’s economy and shrinking telecom industry, this solution will deliver a global reach for T2 service providers and Enterprise corporations.

The objective of this presentation is to provide a detailed understanding of the operation of:

• Carriers' Carrier (hierarchical) and Multi-AS BGP/MPLS VPN’s as describe in RFC 2547bis. For this scenario, the customer service provider depends on the BGP/MPLS VPN service provider to deliver a transport service between the customer service provider’s POPs or regional networks. If all of the customer service provider’s sites have the same AS number, then the BGP/MPLS VPN transit service provider delivers a carrier-of-carriers service. If the customer service provider’s sites have different AS numbers, then the BGP/MPLS VPN transit service provider supports multi-AS operations.
• L2 MPLS/VPN or VPLS across Service provider boundaries
• Inter-AS Traffic Engineering requirements.
• BGP route optimisation techniques applicable to Multi-AS solutions

This presentation will also focus on interoperability between different vendors to deliver CC and Multi-AS solutions as well as using some L2 MPLS VPN techniques to enhance the QoS requirements.

Some of the key points are:

• MPLS/VPN Carrier of Carrier’s and Inter-Provider Solutions
• Various scenarios, technical solutions and limitations
• L2 MPLS/VPN or VPLS across Service provider boundaries
• MPLS Inter-AS Traffic Engineering requirements and solutions
• Security issues/solutions
• End-to-End QoS

Case Studies:

• L3 Connectivity’s between SP’s and Enterprises
• Deliver global rich for National Telco’s
• Applications over CC and Multi-AS networks
• Vendor’s interpretabilities and issues
• FLAG Telecom Case studies and experience.
