Greetings, all, FYI, for those of you not on ietf-announce...
Cheers, Brian Begin forwarded message: > From: IAB Chair <[email protected]> > Subject: Call for Papers: IAB Workshop on Stack Evolution in a Middlebox > Internet (SEMI) > Date: 9 Sep 2014 18:09:43 GMT+2 > To: IETF Announce <[email protected]> > Cc: IAB <[email protected]>, IETF <[email protected]> > Reply-To: IAB <[email protected]> > > IAB Workshop on Stack Evolution in a Middlebox Internet (SEMI) > 26-27 January 2015 – ETH Zürich, Switzerland > > The Internet’s transport layer has ossified, squeezed between narrow > interfaces (from BSD sockets to pseudo-transport over HTTPS) and > increasing in-network modification of traffic by middleboxes that make > assumptions about the protocols running through them. This ossification > makes it difficult to innovate in the transport layer, through the > deployment of new protocols or the extension of existing ones. At the > same time, emerging applications require functionality that existing > protocols can provide only inefficiently, if at all. > > To begin to address this problem, the Internet Architecture Board (IAB), > within the scope of its IP Stack Evolution Program, is organizing a > workshop to discuss approaches to de-ossifying transport, especially > with respect to interactions with middleboxes and new methods for > implementing transport protocols. Recognizing that the end-to-end > principle has long been compromised, we start with the fundamental > question of matching paths through the Internet with certain > characteristics to application and transport requirements. Which paths > through the Internet are actually available to applications? Which > transports can be used over these paths? How can applications cooperate > with network elements to improve path establishment and discovery? Can > common transport functionality and standardization help application > developers to implement and deploy such approaches in today’s Internet? > Could cooperative approaches give us a way to rebalance the Internet > back toward its end-to-end roots? > > Topics > > For this workshop we would like to consider topics that speak to these > questions, including the following: > > - Development and deployment of transport-like features in application- > layer protocols > - Methods for discovery of path characteristics and protocol > availability along a path > - Methods for middlebox detection and characterization of middlebox > behavior and functionality > - Methods for NAT and middlebox traversal in the establishment of end- > to-end paths > - Mechanisms for cooperative path-endpoint signaling, and lessons > learned from existing approaches > - Economic considerations and incentives for cooperation in middlebox > deployment > > We will explicitly focus on approaches that are incrementally deployable > within the present Internet. > > The outcome of the workshop will be architectural and engineering > guidance on future work in the area, published as an IAB workshop > report, based on discussion of proposed approaches; future work will be > pursued within the IAB Stack Evolution Program. We will also explore > possible areas for standardization, e.g. new protocols that separate > signaling to and from on-path devices and common transport semantics > from the rest of the transport protocol; and for general guidance, e.g. > how transports as well as middleboxes can be designed and deployed to > achieve these goals. > > Submission Instructions > > Attendance at the workshop is by invitation. Prospective participants > are invited to submit short position papers outlining their views on one > or more topics related to the scope of the workshop. Position papers > will be published on the IAB website at: > http://www.iab.org/activities/workshops/semi/. > > Submissions accepted at: > https://www.easychair.org/conferences/?conf=semi2015 > > Submission Deadline: 31 October 2014 > > Notification Deadline: 17 November 2014 > > Workshop Dates: 26-27 January 2015 > > Sponsored by the Internet Architecture Board, the Internet Society, and > ETH Zürich.
