The transport layer of the Internet has become 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.

Report from the IAB Workshop on Stack Evolution in a Middlebox Internet (SEMI)
The Internet Architecture Board (IAB) through its IP Stack Evolution
program, the Internet Society, and the Swiss Federal Institute of
Technology (ETH) Zurich hosted the Stack Evolution in a Middlebox
Internet (SEMI) workshop in Zurich on 26-27 January 2015 to explore
the ability to evolve the transport layer in the presence of
middlebox- and interface-related ossification of the stack. The goal
of the workshop was to produce architectural and engineering guidance
on future work to break the logjam, focusing on incrementally
deployable approaches with clear incentives to deployment both on the
endpoints (in new transport layers and applications) as well as on
middleboxes (run by network operators). This document summarizes the
contributions to the workshop and provides an overview of the
discussion at the workshop, as well as the outcomes and next steps
identified by the workshop. The views and positions documented in
this report are those of the workshop participants and do not
necessarily reflect IAB views and positions.
