I've just updated our draft on RTP Congestion Control Feedback to address feedback from Jonathan Lennox based on implementation experience during the hackathon at the Bangkok IETF meeting.
-
I gave a presentation at the ACM CoNEXT Workshop on Evolution, Performance, and Interoperability of QUIC yesterday, discussing how best to transport real-time traffic over the emerging QUIC transport protocol.
-
I gave a brief update on our work on the impact of encrypting transport-layer protocol headers during the IETF 103 meeting in Bangkok.
-
Jörg Ott gave a short presentation in the AVTCORE working group at the IETF 103 meeting in Bangkok, previewing some work we've been doing on real-time media delivery using the QUIC transport protocol, and how this relates to RTP-based media transport.

10 November 2018 / post-sockets
The Post Sockets cabal was at IETF 103 in Bangkok in November 2018. We gave an update on some recent changes to the Transport Services Architecture to the TAPS working group, and met separately to discuss the next steps towards completing the work.

4 November 2018 / protocol-standards
I'm at IETF 103 in Bangkok this week, along with Stephen McQuistin, where we'll be discussing how to bring more structured and machine readable features to IETF specifications, exploring the attitudes of participants to such formalisms, and trying to understand the barriers to adoption. If you're at the IETF meeting, and interested in these topics, please come and talk to me or to Stephen.

30 October 2018 / protocol-standardsI gave a talk at Loughborough University last week, entitled “Parsing Protocol Standards, Parsing Standard Protocols”, and will repeat it as a Systems Section seminar in Glasgow later today. The talk introduces some of the work we're doing in my EPSRC project on Improving Protocol Standards for a more Trustworthy Internet.

1 October 2018 / post-sockets
Welcome to Mihail Yanev, who started work as a research student under my supervision today.

The 20th Scottish Networking Event was held at the University of Edinburgh on 3 September 2018. SCONE is the Scottish Networking Event, an informal gathering of networking and systems researchers in and around Scotland.
-
19 July 2018 / post-sockets
The Post Sockets cabal met at IETF 102 in Montreal in July 2018. We gave several presentations to the TAPS working group, to review the status of the Transport Services Architecture drafts, and also held a side meeting to discuss next steps.
-
I'm pleased that the FRμIT project's survey paper on commodity single board computer clusters and their applications has been accepted for publication in the Future Generation Computer Systems journal. This paper is available online now, and will appear in print in December 2018.

21 June 2018 / tcp-hollywood
Saba Ahsan presented our paper DASHing Towards Hollywood at the ACM Multimedia Systems Conference in Amsterdam, The Netherlands, last week. This paper presents an implementation of the MPEG-DASH streaming video standard running over TCP Hollywood, a variant of TCP we've developed that's intended to be better suited for latency sensitive applications than standard TCP.
-
The fourth FRμIT project meeting was held on 23-24 May 2018 at the University of Glasgow. We reviewed progress, and discussed next steps for the PiStack board, peer-to-peer infrastructure, and federated authentication for the FRμIT testbed.
-
Low-cost, low-power edge compute devices and nodes are key components of Internet of Thing (IoT) systems that are embedded in smart homes and smart cities. They generally start small but can rapidly scale to many thousands of nodes. Devices can be inaccessible, mobile, or in private residential locations, so remote administration is essential to deploy updates and install new applications. This begs the question — how can we effectively manage and update such devices?
-
17 May 2018 / post-socketsI attended the W3C Workshop on Web5G: Aligning evolutions of network and Web technologies last week, at the GSMA offices in the City of London, to give a talk about the emerging IETF Transport Services framework.
-
Several members of the FRμIT project attended the IEEE/IFIP Network Operations and Management Symposium in Taipei this week, helping to organise the Workshop on Decentralized Orchestration and Management of Distributed Heterogeneous Things (DOMINOS), presenting on work on Peer to Peer Secure Update for Heterogeneous Edge Devices, and giving a demo of the Pi Stack clustering board for Raspberry Pi systems.
-
Herry gave a talk entitled And what would you do with ten thousand Raspberry Pis? at the UK Systems Research Challenges Workshop in Northumberland on 22 March 2018.
-
21 March 2018 / post-sockets
Slides from the presentations of our proposed transport services architecture at the IETF 101 meeting in London, on 21 March 2018, are now available.
-
13 March 2018 / post-sockets
We've recently submitted two new drafts to the IETF, outlining a proposed Transport Services architecture and associated API, along with a third draft giving some implementation guidance. These drafts represent the merger of the ideas from our Post Sockets proposal, the EU NEAT project, and the Socket Intents project at TU-Berlin. They will be presented in the TAPS working group session at IETF 101 in London, on 21 March 2018.

28 February 2018 / protocol-standards
I'm seeking a postdoctoral research associate to work on the EPSRC-funded project "Improving Protocol Standards for a more Trustworthy Internet". The position involves working with the IETF and research community, to develop semi-formal tools and methods for specifying protocol standards, along with tools to support their use in the IETF community. The goal is to improve the quality of Internet protocol standards.
-
27 February 2018 / protocol-standards
I'm pleased that the EPSRC has agreed to support our work on "Improving Protocol Standards for a more Trustworthy Internet". This is a two year project, funded under the Engineering for a Prosperous Nation call, that aims to make the Internet more robust by improving the way in which the underlying protocol standards are developed. Stephen McQuistin will join the project as a Research Assistant, and I expect to advertise for a further RA position shortly.

The ACM, IRTF & ISOC Applied Networking Research Workshop 2018 (ANRW’18) is an academic workshop that provides a forum for researchers, vendors, network operators, and the Internet standards community to present and discuss emerging results in applied networking research. Our other goal is to create a path for academics to transition research back into the IETF standards and protocols and for academics to find inspiration from topics and open problems addressed at the IETF.

The 19th Scottish Networking Event was held at the University of Aberdeen on 20 February 2018. SCONE is the Scottish Networking Event, an informal gathering of networking and systems researchers in and around Scotland.
-
30 January 2018 / post-sockets
The Post Sockets cabal met with friends from the EU NEAT project, and others, to discuss a unified proposal for the IETF Transport Services architecture and associated API. This is intended to form the basis for future work in the IETF TAPS working group, and will be discussed in their upcoming meeting at IETF 101 in London, in March 2018.
-
FRμIT project member Herry gave a presentation at the HiPEAC workshop on Heterogeneous and Low-Power Data Center technologies earlier this week. He spoke about peer-to-peer secure updates for Raspberry Pi devices, and the prototype system that Emily Band developed during her summer internship last year.
-
The third FRμIT project meeting was held on 16 January 2018 at the University of Southampton. The main focus of the meeting was the security and authentication infrastructure requirements for the FRμIT stack, and whether these can satisfied by the Jisc Moonshot implementation of the IETF ABFAB protocols. We also discussed progress with the Pi Stack power supply board for high-density Raspberry Pi clusters.
