Dear David, Jon and all,
Re: engaging with mobile VCE
Last summer the next generation wireless networks group (which essentially
came out of mobile VCE) had a town hall meeting that resulted in a strategy
document that outlines their visions for the challenges in wireless
communications up to 2020, see
http://www.ngwnet.ac.uk/files/NGWN_summary.pdf
A few of us (e.g. Dave Parish and I) who are involved in both communities
were involved in putting together parts of this document (section 4).
Although much of this document might be regarded as very low level from a
networking community perspective, I feel there are a number of issues and
opportunities identified in it that are common to both communities.
Like NGN, this community intends to approach EPSRC (most likely John and
Nafeesa), and I suspect that they will almost certainly tell both
communities to engage with each other.
OK, for my 10c input, I think that if we are considering a future internet
that has ubiquitous access, or a multitude of types of access (particularly
over wireless networks), then managing trust and reputation become key
issues. I may be wrong but I don't see this being covered in GENI/FIND at
present.
Additionally, one might consider how to design networks (not end systems)
that are tolerant to certain levels of intrusion/ attack (this would be
particularly relevant to wide area wireless, and wireless mesh networks
which in the future might be expected to operate under the threat of
constant or persistent attacks). This is kind of mentioned by FIND in
"...will address requirements such as core functionalities, security,
robustness, openness, economic utility, and social needs as well as support
for new technologies and services.", but this is extremely general and I
think it could be greatly clarified/expanded.
Finally, on the subject of Click/ xen etc, I work with a well-known FPGA
company that are now able to directly synthesise from Click to their
programmable hardware (for me it beats programming NPUs every time), shame
we don't have this for xen, or do we?
I hope this helps, and doesn’t ruffle too many feathers.
Best Regards,
Alan

Jon, Chris, all,
Those involved in organising Cosener's this year need to consider what
John says about engaging with the Ubicomp and MVCE folks -- with some
thought about how we would all fit into the space ...
I like Chris's suggestions of inviting Dave Clark (or someone else?) and
Andrew Herbert.
Meanwhile, can those of you who have indicated you'd like to be involved
in responding to the NSF people send me a few words about what you'd
like included: Chris and Jon have started the ball rolling with their
initial thoughts.
And I will contact John Hand and Nafeesa Simjee at the EPSRC to tell
them about this.
Regards,
David

virtualisation is a tool - not a problem - i outlined 3 problems not
addressed by GENI/FIND (much) two at least of which might be addressed
by virtualisation, (business models and control of unwanted traffic),
and the third (infrastructure free wireless wide area networks ) might
use virtualisation as part of resource management (e.g. spectrum -
doncha just love the idea of virtual spectrum - kind of like abstracting
thin air)
by the way, andrew didn't explicitly outline it, but the combination of
xen and xorp is quite widespread in the network virtualisation emergent
community (there are other choices for network/OS virtualised stack,
but even those, e.g. click, include some of xen or vservers or some way
to get a higher level management API)
oh, and while I am whingeing:
a big problem i have with coseners recently is the lack of (well,
decreasing) engagement with the ubicomp and and mobile VCE community
