Client-based WDS: Providing Application Acceleration in Mobile and VPN Environments

Wide-Area Data Services (WDS), aka "WAN Optimization" is becoming the most effective way to improve application performance while reducing network traffic. In scenarios where there is significant network latency that would otherwise render many applications unusable, WDS can deliver almost LAN-like speed. Where bandwidth constraints exist and there is no practical or economical option, WDS can help reduce network traffic, allowing you to postpone or avoid circuit upgrades altogether. The technology provides the ability to centralize applications and servers, furthering the cost savings on hardware, software licensing, maintenance and the operation of a distributed architecture. more

How Tiered Internet Pricing Could Actually Facilitate P2P

Time Warner Cable's planned experiment with tiered charging for Internet access has generated a flurry of coverage in the blogsphere, but no new insights (at least that I've seen). The primary problem ISP's complain about is that 5% of their customers use 90% of the available bandwidth and when they examine this traffic, it's mostly peer-to-peer file sharing... more

Google Playing to Win in the 700 MHz Auctions

Many say Google will bid to lose in the upcoming 700 MHz auctions and many more are equivocating. The idea is Google's entry alone will induce enough openness, and besides they couldn't afford to become an operator. This shows a total lack of understanding! more

Up to 300 Megawatt Worth of Keepalive Messages to be Saved by IPv6?

The Time Square Ball bringing in 2008 had more than 9,500 LED bulbs displaying 16 million colours while consuming power equivalent to about ten toasters. This compares to 600 incandescent and halogen bulbs adorning last year's Ball. Easy to forget that most mobile devices used by Time Square revelers were behind IPv4 NAT's and that always on applications such as Instant Messaging, Push e-mail, VoIP or location based services tend to be electricity guzzlers. It so happens that applications that we want always to be reachable have to keep sending periodic keepalive messages to keep the NAT state active... more

Will 2008 be the WiMAX Year?

There has recently been some good and bad news about WiMAX. On the good news part, an announcement made by the WiMAX Forum this month regarding the launching of the Mobile WiMAX certification program through which vendors can get their IEEE 802.16e-2005 equipment tested and possibly certified... On the bad news part, there was the Sprint-Clearwire breakup after three months of announcing a plan to join forces in building a nationwide WiMAX network in the US. Although it is anticipated that each company would carry on with its own WiMAX plans, analysts believe that the breakup would have negative impact on WiMAX deployment in the US... more

Verizon OPEN Wireless

Very surprising and welcome announcement from Verizon Wireless yesterday announcing that "it will provide customers the option to use, on its nationwide wireless network, wireless devices, software and applications not offered by the company. Verizon Wireless plans to have this new choice available to customers throughout the country by the end of 2008..." And Verizon Wireless is right to open up. There's plenty of room to be cynical about this; after all, Verizon Wireless is trying to STOP the FCC from putting an openness requirement on the 700Mhz spectrum to be auctioned... more

Making the Wireless World More Web-Friendly

Your wireless carrier (in the U.S., probably AT&T or Verizon Wireless) has a lot of control over the handset you can use and the applications that can run on that device. In fact, wireless carriers routinely ask for (and get) an enormous slice of the revenue from applications that work on their networks, and they force handset manufacturers to jump through all kinds of hoops in order to be allowed to sell devices that can connect to these networks... This has had bad effects on the ecosystem of the wireless world. more

Comcast’s Wrong Approach

Internet Service Providers (ISPs) have to do a lot more than just provide a pipe from your residence to their facilities to assure that you have a good Internet experience. There is a raging debate, inextricable from the debate on Network Neutrality, both on what the proper responsibilities of an ISP are AND what methods are proper for carrying out those responsibilities. more

A Packet of Lies

I've been reading the kerfuffle around Comcast's blocking of various random network protocols with interest. Whilst I remain convinced that blanket "network neutrality" legislation remains just a form of digital gripe water (cures colic for cybernauts), there's clearly a problem. As I previously alluded there's a definite consumer protection issue over what you buy when it says 'Internet' on the tin. So here's tuppence worth of additional input... more

FON and BT: Wifi Today; Mobile Tomorrow?

A deal announced today between British Telecom and upstart FON allows BT's Internet customers to share their own broadband connections via WiFi and, in turn, be able to access WiFi free at "thousands" (doesn't say how many) of FON hotspots around the world operated by other Foneros... When you buy home Internet access from BT and opt into this plan, you are also buying roaming access at no extra charge. The technology is supposed to assure that the part of the connection which you share is segregated from your own access so that there are no security problems caused by the sharing. more
