Research : TCP Hollywood
Ossification of the transport-layer forces networked multimedia applications to use TCP or UDP, despite standardisation of more appropriate alternatives, such as DCCP or SCTP. In this work, we explore the design of TCP Hollywood, an unordered, time-lined, TCP variant designed to better support real-time multimedia traffic, while being widely deployable.
Talk on Lower-latency video streaming with TCP Hollywood
26 September 2016 / tcp-hollywood
I gave a talk entitled Lower-latency video streaming with TCP Hollywood, at the workshop on "Are Networks Ready for Next Generation Video?" organised by Huawei, and held in Berlin on 26-27 September 2016.
Implementing Real-Time Transport Services over an Ossified Network
16 July 2016 / tcp-hollywood
Stephen McQuistin presented our paper on Implementing Real-Time Transport Services over an Ossified Network at the ACM, IRTF, and ISOC Applied Networking Research Workshop in Berlin, on 16 July 2016 (slides). This paper considers the transport services needed by real-time applications, based on a top-down analysis of their requirements, and their implementation on ossified networks such as the Internet, and based on this proposes an abstract transport API. A cut-down version of this talk was also given in the TAPS working group at IETF 96 (slides).
TCP Hollywood prototype: source code
20 May 2016 / tcp-hollywood
We are pleased to make available the source code for our prototype TCP Hollywood implementation. This is the code used in our recent ACM NOSSDAV 2016 and IFIP Networking 2016 papers. The linked archive contains a patch against FreeBSD 10.1.0, the TCP Hollywood intermediary layer library, and a sample sender and receiver. This code is also available from the University of Glasgow research data repository.
TCP Hollywood at IFIP Networking 2016
19 May 2016 / tcp-hollywood
Stephen McQuistin presented our paper TCP Hollywood: An Unordered, Time-Lined, TCP for Networked Multimedia Applications at the IFIP Networking 2016 conference in Vienna, Austria, on 19 May 2016 (slides). This paper describes the design of TCP Hollywood, and presents analysis showing when it will improve performance compared to standard TCP.
TCP Hollywood at ACM NOSSDAV 2016
13 May 2016 / tcp-hollywood
Stephen McQuistin presented our paper TCP Goes to Hollywood at the ACM NOSSDAV workshop in Klagenfurt am Wörthersee, Austria, on 13 May 2016 (slides). This paper introduces TCP Hollywood, a new TCP variant that aims to reduce transport-induced latency for multimedia applications. It gives an overview of the protocol, and outlines the conditions where it offers benefit over standard TCP.
New research student: Stephen McQuistin
4 October 2014 / tcp-hollywood
Welcome to Stephen McQuistin, who starts work as a research student under my supervision today. Stephen is funded by a College of Science and Engineering scholarship, and will be working on exploring the design space for deployable multimedia transport protocols.
