IETF vs ITU-T Scope

• What is the IETF Scope in this area and what is
  the ITU-T scope?
• Both PWE3 and ITU-T have duplicated efforts on PW
• IETF is the design authority for IP and MPLS
• Work is needed on PW inter-working which not a
  traditional IETF work area
• Resolution of scope is an IETF policy issue.

PWE3 Phase Two requirements

• Focus to date has been SPs who wanted todeploy
  greenfield converged services networks as opposed
  to augmenting existing services. Early adopters
  did not have traditional service, and were
  wishing to offer it in competition to the
  incumbent, or wished to restrict CAPEX expense on
  traditional equipment.
• New requirements emerging from incumbents that
  wish to migrate to a converged MPLS core.
• Must establish if there are any enterprise
  requirements.

5
Encapsulations

• There are some issues concerning transparency
• FCS
• MPLS PWs header translations
• Need to add HDLC PPP

6
SPVC interworking

• Most networks require a migration process from
  traditional to PW.
• It is clear from the list that this is an area
  that needs to be addressed.
• Significant debate on the list regarding PWE3
  competence and IETF scope in this area.
