Why MPLS-based Architecture?
Network and Service Convergence
•
•
One highly scalable and robust core network to support Convergence:
–
Voice, Video and Data Convergence
–
Intranet, Extranet and Internet Convergence
–
Layer 2 and Layer 3 service convergence
An Infrastructure that provides for easy migrations and interoperability between
different endpoints.
Built upon standards-based IP architecture paradigm and elements
•
Transparent to end-user applications
•
Supporting current and emerging application paradigms
Enables multiple logical networks on one common network
infrastructure
•
Logical network for each service (FR, ATM, ETHERNET, Layer-3 VPN, MIS, VoIP)
•
Logical network for each customer intranet/extranet VPN with inherent security
capabilities

How MPLS PNT Works
•
A network based IP VPN
•
Dedicated access with PPP
•
Uses MPLS (IETF Standard RFC 2547) for security
•
•
Provisioned on AT&T’s IP Network
Pure (Native IP) layer 3 solution from premises
to premises
•
Does not use IP SEC (no tunnels, no encryption)
•
•
No additional tunneling hardware needed
Any-to-any connectivity (fully meshed) with
a single connection at each site.
Data Packet
Two Labels
The inner label
(second-level) identifies
the destination VPN and
customer address
Egress MPLS Edge
Router removes labels
