Dry-Martini: Run PWE3 over Any Sub-IP

1
Dry-Martini Run PWE3 over Any Sub-IP

• Ping Pan
• Hammerhead Systems
• IETF 60

2
Pseudo-wire in Perspective

• An IP-centric technology to deal with sub-IP
  traffic
• An aggregation mechanism
• Draft-martini never exclude the kind of PSN to be
  used
• so long there is a tunnel, here comes the
  pseudo-wires
• So, whats the fuss?

How Dry?
LDP to exchange MPLS labels

• More than MPLS Backbone
• More than PSN
• its any Net

4
Is this useful? You bet!
IP/MPLS Backbone
ATM/Frame Network
TDM Transport
5
What to standardize, and why IETF?

• Transport networks cannot route LDP messages.
• Need to a special label to tunnel them through.
• Such as Explicit-Null
• In the context of PWE3 data transport
• All PEs share the same IP capability
• Only use IETF defined PWE3 encapsulation
• No need to define and reinvent it else where
