Google And Broadband-Monitoring Tools

clock June 22, 2008 21:49 by author anjel

When it comes to your broadband connection Google wants you to know that it has your back. The Internet giant is developing a suite of tools to help broadband users identify traffic discrimination by their Internet service providers. "We're trying to develop tools, software tools...that allow people to detect what's happening with their broadband connections, so they can let (ISPs) know that they're not happy with what they're getting--that they think certain services are being tampered with," Google Senior Policy Director Richard Whitt said Friday morning during a panel discussion at the Innovation '08 conference in Santa Clara, Calif. "If the broadband providers aren't going to tell you exactly what's happening on their networks, we want to give users the power to find out for themselves."

Whitt argues that innovation among application developers will stagnate without neutral networks, and he wants to see consumers join an "arms race" for Net neutrality--the idea that network operators shouldn't be allowed to discriminate against content or applications or charge extra fees.

"The forces aligned against us are real. They've been there for decades. Their pockets are deep. Their connections are strong with those in Washington," he said. "Maybe we can turn this into an arms race on the application software side rather a political game."

Whitt would not say when the tools will be available or how they would work, but did indicate that Google engineers had been working on them for a while.

The issue came to a head last August when TorrentFreak reported that Comcast was surreptitiously interfering with file transfers by posing as one party and then, essentially, hanging up the phone. Comcast denied the allegation, but tests conducted by the Associated Press showed Comcast was actively interfering with peer-to-peer networks even if relatively small files were being transferred.

In response, the Federal Communications Commission announced it would investigate the charges, and in May, a bill was re-introduced into Congress that would rewrite U.S. antitrust law to prohibit network operators like AT&T and Comcast from blocking, impairing, or discriminating against "lawful" Internet content, applications, and services or from charging extra fees for "prioritization or enhanced quality of service."

Google has long argued that it's necessary to enact new regulations barring such activity, while broadband operators like AT&T and Comcast counter that the market will solve any perceived problems.

Network monitoring tool released by GÉANT2 to boost network efficiency for scientists & researchers

clock June 12, 2008 21:31 by author anjel
GÉANT2, the high bandwidth, pan-European research and education network, has announced the release of the latest software bundle that is used to deliver the perfSONAR multi-domain monitoring (MDM) service across a number of key European National Research and Education Network (NREN) sites.
  This release is the result of collaborative efforts from 11 different organisations around the world and forms the first stage of the full deployment of the perfSONAR MDM service across the whole GÉANT2 pan-European backbone.

The perfSONAR MDM service enables fast troubleshooting by providing secure, user-friendly access to standardised network performance metrics from multiple domains. Using its out-of-the-box or customised web-interfaces, network problems and performance bottlenecks can be tracked and resolved, and potential performance issues can be identified. Specifically, information that network administrators access through perfSONAR MDM has the same meaning across the board enabling operators to discuss problems which span multiple domain boundaries on a communal basis and to collaborate more successfully.

International research collaboration is now reliant on high speed connections across multiple local, national and international networks. This growing complexity makes being able to pinpoint and eliminate problems much more difficult, due to the number of dissimilar networks involved. The new state-of-the art perfSONAR tools and infrastructure have therefore been created to enable network administrators to quickly find and deal with issues, irrespective of domain and location, to ensure fast, reliable and uninterrupted connections at all times for researchers across Europe.

Dai Davies, General Manager, DANTE said: “Today’s researchers need to be able to collaborate with their peers around the world, at high speed and in real-time. Consequently, the complexity of working across multiple networks spanning thousands of miles and disparate protocols must not interfere with research work. The perfSONAR MDM tool avoids downtime by allowing fast diagnosis and correction of network problems, wherever they occur. As a result, this will help increase the level of high speed research networking and collaboration across the globe.”

The perfSONAR MDM bundle comprises a full package of open-source based software, usage support and deployment/configuration support. It is currently aimed at network administrators in the global research community with the future option of deployment in the commercial sector.

perfSONAR MDM is made up of an advanced user interface layer, a modular set of web services to access performance metrics and a layer of domain-specific measurement tools. These can all be accessed through a range of visualisation tools which allow users to query and view network end-to-end performance data in an intuitive, user-friendly way.

About GÉANT2:
GÉANT2 is an advanced pan-European backbone network that interconnects National Research and Education Networks (NRENs) across Europe. With an estimated 30 million research and education users in 34 countries across the continent connected via the NRENs, GÉANT2 offers unrivalled geographical coverage, high bandwidth, innovative hybrid networking technology and a range of user-focused services, making it the most advanced international network in the world. Together with the NRENs it connects, GÉANT2 has links totalling more than 50,000km in length and its extensive geographical reach interconnects networks in other world regions to enable global research collaboration. Europe’s academics and researchers can exploit dedicated GÉANT2 point-to-point links, creating optical private networks that connect specific research centres.

GÉANT2 is co-funded by the European Commission under the EU’s Sixth Research and Development Framework Programme. The project partners are 30 European National Research and Education Networks (NRENs), TERENA and DANTE. GÉANT2 is operated by DANTE on behalf of Europe’s NRENs.

About DANTE:
DANTE is a non-profit organisation, co-funded by the European Commission and working in partnership with European National Research and Education Networks (NRENs) to plan, build and operate advanced networks for research and education. Established in 1993, DANTE has been fundamental to the success of pan-European research and education networking. DANTE has built and operates GÉANT2, which provides the data communications infrastructure essential to the success of many research projects in Europe. DANTE is involved in worldwide initiatives to interconnect countries in the other regions to one another and to GÉANT2. DANTE currently manages projects focussed on the Mediterranean, Latin American and Asia-Pacific regions through the EUMEDCONNECT, ALICE and TEIN2 projects, respectively.

About PerfSONAR:
perfSONAR is a joint collaboration between GÉANT2, Internet2, ESnet and RNP and the wider consortium consists of more than twenty partners, that seek to build network performance middleware that is interoperable across multiple networks and useful for intra-network and inter-network analysis. One of the main goals is to make it easier to solve end-to-end performance problems on paths crossing several networks. For more information and full technical specifications please visit www.perfsonar.net. To download the latest perfSONAR MDM software see PerfSONAR.

IBM Rational Software Developer Conference 2008

clock June 2, 2008 22:07 by author anjel

My guesses for what would constitute the bulk of the show news this week at IBM's 2008 Rational Software Developer Conference seem to have been mostly accurate. It’s teams, it’s collaboration and it’s integration – all within a ‘transparent’ process of course.

Rational Software general manager Danny Sabbah is going for broke on the soundbite front and we’ve already had, “We’ve moved from a time when the network is the computer – to a time when the network is the team,” and the even snappier, “You’ve got two ears and one mouth and it’s that way round for a reason.”

t’s bigger this year though: 3500 developers, 300 sessions across 14 tracks and more Jazz-related product announcements than you can easily digest in a single serving. Note: it may just be a US-UK language thing, but when IBM says that most of its Rational portfolio will incorporate Jazz technology over the “next several years” – is that because they didn’t like to say “next few years”, or because they wanted to leave the door open for some ambiguity?

Open-source nirvana

Either way, we’re being urged to read Eric Raymond's book The Cathedral and the Bazaar this week as it details the move from the “confines and restrictions” of the cathedral to the “openness” of the bazaar. This tome will no doubt already be well known to those who seek enlightenment on the path towards open-source methodology nirvana.

The latest musings on the subject of software development as a whole made for pretty interesting listening at this morning’s keynote – and in between various dancers, comedians and speakers we got an insight into what IBM sees as the “state of the application environment” in 2008.

According to Dr Sabbah, we’re currently we’re looking at a situation with high maintenance costs, too many versions from too many vendors - and all this leads to poor visibility into our portfolios and unchecked proliferation of software that is often updated and replaced, but should really be retired.

Not making the big splash keynote headlines of some of this week’s announcements but definitely interesting was a quick chat I had with IBM’s Laura Bennett who is the senior software engineering manager of alphaWorks.

Over the last year, alphaWorks focus on early prototypes (some of which migrate to IBM developerWorks) has been extended to be more available to the student community. Although Bennett describes these with IBM terminologies such as ‘a new delivery model’ and ‘service’, essentially what it means is that a new communication channel is open for students of software engineering (in all its forms) to pose questions to the alphaWorks lab researchers.

It sounds like pretty cool stuff, as to how much IBM steers, owns or directs the creation of prototypes at this level I can’t say – but I will find out.

Big numbers

Back to the core news of the conference and there’s a rich scent of scepticism in the press room this afternoon as to whether all this talk of collaborative team development is coming from a company that itself may be argued to suffer from disconnected silo structures by virtue of its own sheer size.

But Danny Sabbah used the point of IBM’s size this morning during his speech to make a positively spun comment. He highlighted the fact that Steve Mills, senior vice president for IBM Software Group, runs what the company labels as the world's largest software development organisation. IBM makes this claim as it states that, on a global level, it has more than 25,000 developers in 77 locations focused on developing software. So, says Sabbah, the company can act as an extremely large-scale user of its own products and this helps testing and development.

Sabbah also specified that the development of any one particular product may involve a mix of technologies from agile to iterative to waterfall and that the perfect blend will depend on the task in hand.

You need proof? It’s survey time!

Colleen Arnold also made an appearance this morning at the keynote session. Arnold is general manager for IBM’s global application services division and she presented the results of what IBM calls its Global CEO Study – a survey it undertakes every couple of years. If you had any scepticism over whether there really is a burning need to extend our capabilities in ‘collaborative’ software application development, Arnold’s carefully selected results should allay your fears.

The latest findings state that: “Management of global applications, processes and systems with consistency, quality and security … all depending on collaboration and teamwork…”, is at the forefront of those CEOs surveyed. Happy now? Hmm, I thought not – well, let’s keep looking, reading and thinking.

Finally today, I had a session with Scott Ambler who is global lead (or practice leader if you prefer official designations) for IBM’s Agile development unit. We spoke about the ‘belief’ or ‘leap of faith’ element behind Agile and the fact that some disagree with it while others are firm converts.

Ambler insisted that Agile will always be with us despite the fact that many developers don’t buy it. “Many developers who criticise Agile have probably never tried it,” said Ambler. “If it is like a religion, then if you continue to discuss it you will never reach a real agreement and consensus and find belief,” he added.

Part of the problem is that Agile depends on highly collaborative environments where there is a high degree of team trust (now you know why Ambler is here this week) – and so it does suffer from a lack of adoption in areas where those factors do not exist such as, according to Ambler, government and what used to be Russia.

We’re only 24 hours in and many of us already have news overload syndrome, but that is expected and it’s probably better to get a heads up on the big announcements early rather than in staggered form. In the words of IBM’s vice president for marketing and strategy Scott Hebner, “We’ve seen the biggest product announcements ever under the Rational brand this week.”

The times they are a changin’

Tonight though it’s a case of The times they are a changin’ – as our evening “do” is a performance from the Wallflowers whose lead singer Jakob Dylan is in fact the son of Bob. Will tonight’s bash provide us all with a clear head for tomorrow’s Grady Booch keynote? The answer my friend is blowing in the wind.

Sorry – couldn’t help that, long day.
