What If I Were Wrong About Edge-Caching?

Nicholas Thompson at Wired Blog sums up yesterday's Wall Street Journal piece on Google. To summarize his summary: Google's edge caching isn't new or evil; Lessig didn't shift gears on NN; Microsoft and Yahoo have been off the NN bandwagon since 2006; The Obama team still supports NN; Amazon's Kindle support is consistent with its NN support. Yet... yet... more

Does Bell Really Have a P2P Bandwidth Problem?

Bell filed its response to the Canadian Association Of Internet Providers (CAIP) submission to the Canadian Radio-television and Telecommunications Commission (CRTC) on its throttling practices yesterday, unsurprisingly arguing that its actions are justified and that there is no need to deal with the issue on an emergency basis. Several points stand out from the submission including its non-response to the privacy concerns with deep-packet inspection... and its inference that P2P usage could be deemed using a connection as a "server" and therefore outside the boundaries of "fair and proportionate use" under typical ISP terms of use. more

Transformation - the Real Business Case for NFV and SDN

2016 has seen a steady flow of announcements on successful Network Functions Virtualization (NFV) Proof-of-Concept deployments, mostly focused on virtualizing Customer Premise Equipment (vCPE). This has been a relatively straight forward starting point because unlike many other NFV applications, the vCPE use case does not involve complex activities like having to scale in or out individual services. more

Networks and Nationalization

This post isn't about -- or isn't only about -- the use of computer technology to commit crimes. It's more about the use of computer technology to commit war. A few weeks ago, I was part of a conversation about the legal issues cyberwarfare raises. We were talking about various scenarios -- e.g., a hostile nation-state uses cyberspace to attack the U.S. infrastructure by crippling or shutting down a power grid, air traffic control systems, financial system, etc. Mostly, we were focusing on issues that went to the laws of war, such as how and when a nation-state that is the target of a cyberattack can determine the attack is war, rather than cybercrime or cyberterrorism. more

The U.S. Fiber Expansion Craze

I've written several times recently in blogs that there is a growing backlog in buying fiber cable. Some of the backlog is due to the general supply chain malaise that seems to be affecting almost everything we buy. During the recent gas shortages in North Carolina, I found out that there is a shortage of truck drivers. Apparently, many truck drivers found something else to do during the pandemic, and now there is a shortage of drivers to deliver the many goods that are shipped by truck. more

Email Snooping Can Be Intrusion Upon Seclusion

Analysis could also affect liability of enterprises using cloud computing technologies... Local elected official Steinbach had an email account that was issued by the municipality. Third party Hostway provided the technology for the account. Steinbach logged in to her Hostway webmail account and noticed eleven messages from constituents had been forwarded by someone else to her political rival. more

NANOG 65 Report

NANOG 65 was once again your typical NANOG meeting: a set of operators, vendors, researchers and others for 3 days, this time in Montreal in October. Here's my impressions of the meeting... The opening keynote was from Jack Waters from Level 3, which looked back over the past 25 years of the Internet, was interesting to me in its reference to the "Kingsbury Letter". more

VDSL Cabinet Consideration for FttN Roll Outs

Australia will be an interesting test market for VDSL. With a new government and the broadband infrastructure company NBN Co basically in agreement, it is most likely that VDSL will be used to bring for example fast broadband to multi-dwelling units (MDUs). It was mainly for political reasons that the previous government stopped NBN Co deploying the VDSL technology in MDUs for this purpose. Whether or not any more VDSL will be deployed beyond that will largely depend on the NBN Co review of its current plan.  more

Watching North Korea’s Internet Connectivity Go Up and Down Via Twitter

One thing I enjoy about following Dyn Research (formerly Renesys) on Twitter is that they provide quite interesting graphics and charts about Internet outages. They've been tracking North Korea's Internet access quite closely over the past week and their tweets have been quite enlightening. Back on December 22, for instance, DynResearch tweeted a chart showing a 9-hour, 31-minute outage... more

Can SpaceX Launch 30,000 Second-Generation Starlink Satellites? Maybe

The bottom line is that success is not guaranteed, but neither is failure -- there is a non-zero probability of success. On May 26th, SpaceX applied for permission to launch 30,000 "second-generation" Starlink broadband Internet satellites. (Note that the software on Starlink satellites is updated about once a week). The application narrative states that the second-generation satellites will be configured... more

Telesat Begins Testing Low-Earth Orbit Satellite Internet Service

SpaceX and OneWeb get a lot of publicity and have ambitious plans, but Telesat is the first low-Earth orbit (LEO) satellite Internet service provider to begin testing with potential resellers. Last January, Telesat launched a demonstration satellite and it is now ready for testing. Maritime connectivity provider OmniAccess and Australian ISP Optus had committed to testing the system previously and this week they were joined by in-flight entertainment company Global Eagle Entertainment. more

Global 5G Connections Expected to Reach 1.9 Billion by End of 2023 and 5.9 Billion by End of 2027

The fifth generation of wireless cellular networks, "5G", has seen remarkable growth in the last year, reports industry trade organization 5G Americas. more

NSA, Prism and Internet Exchange Points in Canada

As the operator of the registry for the .CA top-level domain and the domain name system (DNS) infrastructure that supports it, I am uncomfortable, though not surprised, with the knowledge that a government is monitoring the activities of Internet users. And while recent reports about the National Security Agency's top-secret PRISM program actively monitoring Internet users in the United States and (by default) citizens of other countries - Canada included - are on the front page of newspapers around the world, Internet surveillance is not exactly new. more

Quantifying Internet Shutdowns: ISOC Introduces the NetLoss Calculator

In light of the ongoing Internet shutdowns, such as the recent government-ordered Internet disruption in Algeria aimed at curbing cheating during national exams, the Internet Society (ISOC) has unveiled a tool, the NetLoss Calculator. This tool calculates the economic costs of internet shutdowns, a feat that has been a significant challenge until now. more

Thus Ends the Stupid Network Model?

There is an article in EETimes by Fay Arjomandi of Vancouver-based Mobidia that may shake up the fans of the 10 year old stupid network principle. The stupid network essay calls for intelligence to reside at the edge of the network, rendering IP networks to plumbing pipes -- with carriers ignorant of the application and services being transported. more
