Making the Web Faster: Google Working on Enhancing Transmission Control Protocol (TCP)

As part of its efforts to speed up the delivery of web content, Google has proposed changes to Transmission Control Protocol (TCP), "the workhorse of the Internet." Yuchung Cheng who works on the transport layer at Google wrties: "To deliver content effectively, Web browsers typically open several dozen parallel TCP connections ahead of making actual requests. This strategy overcomes inherent TCP limitations but results in high latency in many situations and is not scalable. Our research shows that the key to reducing latency is saving round trips. We’re experimenting with several improvements to TCP." more»

Filtering Spam at the Transport Level

An interesting new paper from the Naval Postgraduate School describes what appears to be an interesting new twist on spam filtering, looking at the characteristics of the TCP session through which the mail is delivered. They observe that bots typically live on cable or DSL connections with slow congested upstreams. ... This paper tries to see whether it would be practical to use that info to manage spam in real time. more»

DDI Integration: We Need IPAM

I am a big fan of DDI (DNS, DHCP and IPAM) as magical trio to manage all transactions on network infrastructures... Or to say the least: make it possible. Basically it makes these "Core Network Services" concise, manageable and integrated. It basically makes the network infrastructures of today and the future possible. There is however one thing that continuously seems to irritate when talking about integrating these services on networks. more»

Packet Latency Big Issue in Internet-Based Applications,

Doug Madory reporting in Renesys Blog: "Packet latency is a big issue in Internet-based applications (i.e. the stuff in the cloud). In conducting analysis on Internet infrastructure over the years, we have seen many patterns of connectivity. One such pattern that can wreak havoc on latency is 'hair-pinning', a phenomenon where traffic takes an unnecessarily long physical path between two points on the Internet due to suboptimal routing. The increased distance results in increased latency, and the 'lag' or 'sluggishness' that users experience as a result can hinder latency-sensitive online applications whether they are financial trading applications or MS SharePoint." more»

Neustar Professional Services: Additional Expertise to Improve Productivity

While it would be nice if your company had IT staff members that were experts in every technology, that is just not realistic. And today, many companies face the challenge of finding the appropriate and specialized expertise that is required to deal with ongoing issues such as network optimization, performance degradations, network risks, and more. more»

We've used this opportunity to invite him to produce the 'Interesting Graph of the Week'. Geoff has been monitoring the global routing system for many years. Here are his most recent observations. more»

.Nxt - You Are All Cordially Invited

There are only a few occasions in any of our lifetimes where what we know and have grown used to is turned on its head. We have now lost the generation that heard radio for the first time; there are only a few who can recall the first television pictures; but many, many more saw color appear on their screens for the first time. more»

Transparency Comes to Load Testing via the Cloud

The importance of online presence continues to grow exponentially. More and more of our personal and professional endeavors are conducted online. Because of this, the ability to ensure a good experience for our online friends and customers also is increasing rapidly. At its core, load testing is nothing more than ensuring your online presence is ready for the number of visitors you expect. It's simple to explain, but historically it's been anything but simple, or easy to afford. more»

IPv6: The High VoLTEage Telephony Generator

According to IDC, smartphones outsold personal computers, laptops included in Q4 2010! Nokia just announced the demise of the Venerable Symbian in favour of Windows 7 phone and Microsoft's bing search engine! Tectonic shifts are under way to adapt to the rise of wireless broadband, an all IP world, and the growing weight of Apple and Google Android.

How a Routing Prefix Travels Through the Internet

What happens when an IP address prefix gets announced or withdrawn. How does this information propagate through the Internet? And how does it affect the amount of Border Gateway Protocol (BGP) traffic across the Internet when a single prefix is freshly announced or withdrawn from the global routing table? The following short analysis shows the detailed effects of these two events. more»
