The IESG has approved the following document: - 'MTU and Fragmentation Issues with In-the-Network Tunneling ' <draft-savola-mtufrag-network-tunneling-05.txt> as an Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Mark Townsley. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-savola-mtufrag-network-tunneling-05.txt Technical Summary Tunneling techniques such as IP-in-IP when deployed in the middle of the network, typically between routers, have certain issues regarding how large packets can be handled: whether such packets would be fragmented and reassembled (and how), whether Path MTU Discovery would be used, or how this scenario could be operationally avoided. This memo justifies why this is a common, non-trivial problem, and goes on to describe the different solutions and their characteristics at some length. Working Group Summary This is an individual submission. It was not discussed in any working group, but was discussed on the int-area mailing list. One negative comment was that, while the document isn't necessarily bad, it doesn't contain enough new and useful information to elevate it to RFC status. There was some associated philisophical discussion about what should/should not become an RFC. Protocol Quality This is an overview of current practice. Call for review was made to the int-area list. This document was reviewed by Mark Townsley. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
