Dear Colleagues,

We are very pleased to announce that the 1st International Workshop on Future of Internet Transport (FIT 2017) will be held on June 12, 2017, in Stockholm, Sweden (co-located with IFIP NETWORKING 2017). The workshop website is available at: http://networking.ifip.org/2017/index.php/workshops/workshop-on-future-of-internet-transport-fit-2017

Scope and Topics of Interest
---------------------------------------------------

There is an emerging demand by applications for new transport services beyond what TCP or UDP can offer. These new demands stem from a need for more flexible transport services, including the need to cater for very low latency traffic, the ability to more efficiently exploit new access technologies (e.g., cellular networks, WiFi, LEO satellites and possibly combinations thereof) and the need to provide end-to-end functionality in the presence of misbehaving middleboxes.

However, the Internet transport layer has become ossified, making it difficult to introduce new protocols and transport services. There is a "deployment vicious circle", where on the one hand, middlebox operators and vendors have been hesitant to let through traffic from rarely used protocols, and, on the other hand, application developers have been hesitant to employ new transport protocols knowing that they are likely to be blocked by middleboxes.

Several new solutions have been proposed over the recent years to address the need for new services, including SCTP, Google's QUIC, MPTCP and Adobe's RTMFP. Meanwhile the ossification problem has been approached from different angles in order to provide a viable path to facilitate the natural evolution of the Internet transport layer. For instance UDP encapsulation techniques for transport protocols have been employed (used by QUIC, RTMFP, Minion and PLUS) and transport/network "happy eyeballing" mechanisms are considered for providing middlebox traversal (used by Apple and discussed in the IETF). Another instance is the IETF's intention to specify a new transport API that is protocol- and platform-independent and allows the transport stack to independently evolve without requiring application developers to participate in this process, hence breaking the deployment vicious circle.

The FIT 2017 workshop will present and discuss research and development within this problem space. The workshop aims to address these questions: (1) what approach is the most appropriate one for the long-term evolution of Internet transports? (2) how can these different approaches be compatible and interoperable with each other as they are being deployed across the Internet and access links with widely varying characteristics? and (3) which of these approaches provides the best transition path from the current Internet transport architecture to the future transport?

Topics of interest include, but are not limited to:
• Solutions to the Internet transport layer ossification
• Scalable, deployable, extensible and flexible transport protocol and service solutions
• New transport protocols, services and requirements (including extensions to, or evaluations of, e.g., QUIC, SCTP, RTMFP, MPTCP)
• Middlebox traversal techniques and signalling (e.g., ICE, STUN, TURN, UDP encapsulation)
• Service oriented and expressive transport APIs and Berkeley socket API extensions
• Multipath transports and intelligent multipath resource utilization and scheduling
• Transport protocols for data-center networks with implications on the Internet (e.g., DCTCP)
• Transport protocol interactions with the network, e.g., to better interoperate with WiFi, cellular or satellite networks
• TCP/UDP/IP extensions for richer transport services
• Opportunistic use of QoS mechanisms (e.g., DSCP usage in WebRTC)
• Less-than-best-effort transport protocols and services
• Transport selection mechanisms (e.g., happy-eyeballing)
• Transport layer security
• Web-based transport services (e.g., HTTP/2)
• Novel congestion control schemes (e.g. coupled, delay-based, ECN based, Bottleneck Bandwidth and RTT based (e.g., BBR), model based)
• Design and performance of transport protocols in userland
• Transport protocols and solutions for multimedia traffic (e.g., WebRTC, MPRTP, RTMFP)
• Standardization of transport protocols and services
• Novel Internet transport architectures
