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.
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.
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.
I 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.
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.
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.
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?
I gave brief presentations about our proposed RTCP packet format for
congestion control feedback to the
RMCAT
and
AVTCORE
working groups at IETF 101 in London, March 2018.
Slides from the presentations of our proposed transport services architecture
at the IETF 101 meeting in London, on 21 March 2018, are now available.
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.
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.
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.
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.
