Hi, John Bourke wrote: We are about to take receipt of a stream of satellite image data at a rate 150Mbps, growing to 600Mbps over the next four years. [...] As we only have a mandate to distribute to the UK, I am thinking that I can just peer with UK ISPs and deliver the data to their customers. I don't know whether just peer means exclusively peer, or whether it means simply peer in this context. :-) Simple might be stretching it -- Peering is a commercial relationship between two organisations that (should) expect mutual/roughly equal, and these days a more significant monetary benefit. A single service and specialist content originator is likely to find it hard to reach the commercial expectations of some access networks in the UK. That said, there's a human element to any peering decision too, and your product sounds really cool so you will likely get some sessions on the basis that we're all nerds and SATELLITES ARE WAY COOL. Do you have a service now that is basically what you'd do on day one ? I have all manner of scripts at the office that can neatly predict inter-network traffic flow that I'd be happy to run on logs that you have. Essentially because I'm a nerd and as previously established... SATELLITES ARE WAY COOL. Another note - It is likely to be significantly cheaper to try to avoid having to lay large capacity into London from Harwell, e.g. by serving content out of racks in region and populating/feeding the data cache on smaller links from your office for example. IOW, run the fatter pipes the shortest distance. Andy -- Regards, Andy Davidson andy.david...@allegro.net CTO || Allegro Networks UK www.allegro.net || Connectivity You Control
[uknof] Virgin Media - router vs modem?
Hello UK-hive-mind, Long time reader; first time poster. (Well to this list anyway!). I've just brought over an 802.11ac router to the UK and realized the Virgin Media broadband superhub (it's a netgear box) is a router/wifi box. I want to run the new box as the router. It's just an Ethernet box; no cable-modem. Is there a prescribed way to run a connection with Virgin Media in modem mode using their own box; ie run your own router? Do I need to but a modem? The superhub seems to be remotely managed. I don't want to go change things too much. Thoughts? Martin

We had a customer do something similar in Manchester (IFL2 / Reynolds) a few years ago. Their method of ingest (a rack full of digiboxes) was, ahem, interesting to say the least though ;) Rich.
Re: [uknof] Virgin Media - router vs modem?
Hi Martin, If you login it gives you the option to put it in modem mode, if that is not there then you may need to call VM to force a firmware upgrade to show the option. This will disable the wireless and all other router functions and turn it into a modem.

Re: [uknof] Virgin Media - router vs modem?
Hi Martin, I'm sure there's an option in the 'superhub' to put it into modem mode from past experience there used to be.

Re: [uknof] Virgin Media - router vs modem?
I have seen posts where allegedly the later model revisions for the superhub can't be run in modem only mode, but I have a version 2 superhub which runs just fine as a modem, run a cable from it to your device, I think I had to clone the MAC address but that was all I needed to do Martin Macleod-Brown | Infrastructure Engineer - Networks Security Direct line +44 (0)20 7000 7772 | Email mmacl...@london.edu | Mobile +44 (0) 774 8962611 www.london.edu Don't forget, you can now track and update your IT support calls using our new IT SelfService Connect with us: Follow us on Twitter Become a fan on Facebook Please consider the environment before printing this email -Original Message- From: uknof [mailto:uknof-boun...@lists.uknof.org.uk] On Behalf Of Martin J.

Re: [uknof] Virgin Media - router vs modem?
Hi. There is only one (fairly sticky) IP on a residential VM service. We have (not by choice) quite a stack of Mikrotiks’ behind VM routers in bridge mode, and essentially we have to create a VPN tunnel from the MT to “our end” to gain access to SNMP and SSH on the MT. If you SSH to the IP that is supposedly bridged to the MT you get an obvious dropped session (which doesn’t show in a wireshark between the MT and VM router). Same applies to SNMP. Even if you enable the SNMP on the VM box in none bridge mode, you can’t (via the gui and from what I recall via SSH either) enable it on the outside interface. That’s it in summary. Nothing too clever. Peter Knapp From: aled.w.mor...@googlemail.com [mailto:aled.w.mor...@googlemail.com] On Behalf Of Aled Morris Sent: 02 May 2014 10:23 To: Peter Knapp Cc: Martin J.

Interesting - from others' comments here, it sounds like some versions of VM's boxes can be set up as pure L2 modems but others are acting more like L2/L3 proxies than bridges. Aled
[uknof] Bandwidth graphs
We are introducing a new bandwidth collection model, where instead of using off the shelf tools like RRD etc, we are bringing data into a database. The challenge we have currently with this is how to display the data to clients in as pretty a way as possible. We've found the libraries nvd3.org and Google Charts, both which are pretty decent but I have a niggling feeling there is something truly whizz-bang out there. We're happy to pay for something decent. Has anyone got suggestions? -- Ed Butler

There's only so much you can sex up a bandwidth graph - particularly if you want to be able to include it in an email, or print onto a invoice. There's probably more benefit in analysing the graph - peak times, unexpected peaks, min, max, 95th percentile, average, etc. There are various graphing tools out there, most of which will generate pretty good looking graphs, with various levels of work required to achieve. Much depends on what language you're working in, and in what format you want the graphs out. Simon

Logstash is also worth considering, Splunk is good but gets very pricy when you start working with lots of data.

Re: [uknof] Here is a Challenge

Their method of ingest (a rack full of digiboxes) was, ahem, interesting to say the least though ;) Hey, this was my installation! First generation of TV ingest of Zattoo http://www.zattoo.com/ - the setup at IFL/Manchester was built 2007 and survived probably about two or three years (I left Zattoo in fall 2008). Unlike assumed, the IFL/Manchester TV ingest was not DVB-S/DVB-S2, but DVB-T (Terrestrial). At that time we couldn't get a TV antenna installed in Telehouse North, thats why we went to IFL (there was no time for a good evaluation - we've choosen the quickest solution). Not sure about roof access at THN today. Still, while TV ingest was probably a bit awkward abusing common settop boxes (including regular and automated power cycles with APC 7920 to increase reliability), the whole Zattoo thing was pretty awesome, from a looking back perspective. During the soccer semifinal Germany-Turkey in June 2008 (European Championship) not less than 62000 viewers were served via over-the-top live IP TV. Still proud on this number. -- Fredy Kuenzler Init7 (Switzerland) Ltd. St.-Georgen-Strasse 70 CH-8400 Winterthur Switzerland http://www.init7.net/
