  1. PWE3 Future Work ItemsPWE3 IETF-59 March 2004 Stewart Bryant <stbryant@cisco.com> Danny McPherson <danny@arbor.net>

  2. Outstanding Items • Complete drafts in progress get published as RFC. • Security. • Congestion.

  3. 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.

  4. 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.
