      encouraged within the Internet
   3. Encourage funding of better tools for remotely controlled traffic
      sources and pro-active problem detection.

3.2. Action Items for IETF Working Group Chairs

   1. NAT: Forward our concerns, problems and suggestions to the
      appropriate working groups
   2. We recommend that IETF should work the issue of Constraint Based
      Routing.
   3. The IETF should encourage work on "wire speed" authentication,
      pair-wise authentication of routers in routing protocols, and
      Byzantine robustness in routing protocols.

   4. Concerns about the Routing Policy Specification Language (RPSL)
      should go to the Routing Policy Systems (RPS) working group chair.
   5. The group recommends a BOF be held on Measuring Path
      Characteristics.  The BOF should consider the data exchange format
      of measurement and mechanisms to distribution of data mechanism.
      It is noted that the IPPM working group is dealing with issues
      within the measurement problem space.
   6. There is layer two work which should be done to support the
      multiple parallel trunks which is outside the scope of the IETF.
      Layer three routing should support richer metrics in OSPF.
   7. SNMP version 3 working groups should be notified about the issues
      about authentication, scope, and rate limiting.
   8. A BOF should be held to plan work on anycast.  A document on
      anycast should be part of the proposed working group charter.

3.3. Action Items for the IRTF Routing Research Group

   1. We recommend that the IRTF Routing Research working group try to
      encourage more analysis of routing data, not just the collection
      of more data.

   2. Encourage evaluation and written reports on the evaluation of
      multicast protocols and mechanisms for different types of
      protocols

   3. The IRTF Routing Research group chair and the Routing Area
      Director should discuss Load Sensitive IGP routing and determine
      whether it is ready for the IETF.

4. Security Considerations

   Security considerations were an important part of the discussions at
   the workshop, but the workshop decided not to publish a summary of
   these discussions.  Other documents that address the issues of
   routing infrastructure security have recently been published.
