PBT and it’s Target Market
Many Service Providers have split decision making and budgeting
• Data Group – IP Router & MPLS Focused
• Transport Group – SONET/SDH & Cross Connect focused
PBT addresses the requirements and operational work flow of the transport group
• Deterministic network behavior
• End-to-end resiliency

PBT key benefits
Deterministic network behaviour
• Nailed-up circuits, no Ethernet learning and flooding
Resilient network designs
• End to end circuit based resiliency
• 50ms failover times
Familiar network operations compared to an MPLS approach
• No need for new personnel with Layer 3 experience
• No need to tackle the complexity of MPLS or MPLS Traffic Engineering
• Maintaining current operational model expected to yield OPEX savings
Significantly lower CAPEX compared to Ethernet over SONET/SDH or MPLS models

Customer Edge (VLAN)
Q in Q Encapsulation
Provider Backbone Bridge (MAC in MAC)
Provides scalability required for service provider deployments
• Eliminates address space scalability issue
• Solves economic issues with MAC table size expansion
Provides backwards compatibility for easy implementations
• Works in conjunction with 802.1ad (Q in Q)
Reduces carrier concerns about building large layer 2 networks

Ethernet NNI to Extend Service ReachAllows peering between provider Ethernet services
Increases carrier reach with Ethernet service extension to off-net sites
Uses a combination of technologies
• Link Aggregation
• VLAN C-VID/S-VID translation
MEF Standard expected later this year

Migration to PBT
PBB (MAC-in-MAC) networks can be deployed today
PBT traffic engineered trunks can be added later
• Both can run on the same switches at the same time
PBT Ready hardware
IP Service Edge or
MPLS Core

PBT versus T-MPLS
SimilaritiesBoth recognize the importance of meshing with service provider transport group requirements
• Connection oriented technology
• Nailed-up circuit support
Both Require a new control plane
DifferencesPBT can support multi-point to multi-point services with PBB
PBT Ethernet OAM better defined than MPLS OAM
PBT leverages the economics of Ethernet
PBT has support from a growing group of influential service providers

Extreme Networks - PBT Product Plans
PBT will be offered on the BD12K and BD10K platforms
Software only upgrade – hardware support is there
New smaller BD12K chassis will launch in April extends PBT closer to the edge and to smaller central offices
Interoperability Demonstration this summer with Nortel
Open interoperability testing later in the year
