Quick quotes please for 100Mbit and 1gbit UK routing table traffic located in RedBus Sovereign House
by Andrius Kazimieras Kasparavičius 17 Sep '07

Hi, I've got a few companies keen to buy "cheaper" "local" LINX traffic. As they are too small to register at RIPE and buy LINX fees and peer, I believe, out there should be companies selling transit to UK routing table at LINX. Aternative UK's IXs would be of interest too. Is it viable service for ISPs these days? Any referals would be appreciated. Thanks

Anyone using uvlan out there?
by Steven Haigh 14 Sep '07

14 Sep '07

A few weeks ago, I stumbled across uvlan... I first thought WTF, then upon researching it a little more, I'm starting to really like the idea for replacing a traditional VPN between sites etc. From the web site: uvlan is a User-space Virtual Local Area Network. In other words, uvlan peers act as nodes on a network switch. Routing ethernet traffic between peers inteligently. Thus allowing for multiple networks to share resources and even IP address space. Some may call it a VPN (Virtual Private Network) application, but it's much more powerful. Differences with traditional VPN technology: 1. It is peer-to-peer 2. It doesn't require licensing 3. It is much simpler 4. It operates at Layer-2 (Ethernet), VPNs generally operate at Layer-3 (IP) Layer-2 applications like gaming can't be supported with Layer-3 tunneling. How does it work? Using the libpcap (winpcap for windows users) library, uvlan listens to a specific ethernet device. If a broadcast frame is seen, then it is sent off to all the peers so they can add it to their records and emit the broadcast on their local network. Once this happens, the device (computer, router, gaming console, etc) which sent the broadcast will be known by all the peers and remote machines will know of the device's existance and how to route traffic to it. This behaviour is identical to a hardware switch. Only difference is - this switch is software and the backplane (the medium that passes information between switch ports) is encrypted packets on the internet. From my understanding, this software is pretty much acting like a bridge, but with endpoints over a routed IP network. Has anyone actually used this? Thoughts? Criticisms? -- Steven Haigh Email: netwiz(a)crc.id.au Web: http://www.crc.id.au Phone: (03) 90001 6090 - 0412 935 897

Article: Abandoned Cable Removal A Dogged Challenge For All Cabling Installatin & Maintenance Magazine By Patrick McLaughlin | July 2007 Issue http://preview.tinyurl.com/32cfak -- As an aside, legend has it that some of the larger skyscrapers in NY City would crumble under the weight of the cables installed inside them --particularly coaxial and proprietary mutli-pair cable runs that were used for market data services and desktop video displays prior to the proliferation of Ethernet over fiber backbones-- running up and down vertical riser shafts, were it not for the bracing and additional structural supports installed after the fact to support them.

What happens then is that things evolve, you run out of space and have to put kit in other racks, run loads of cabling there and then it gets moved again and then you add more cables and then a fibre guy from some telco comes in and puts something else in on top of it. --------------------------------------------------- We are the telco in Hawaii (hawaiiantel.com) and have been around for 125 years.
