A change in the networking landscape – HP to buy 3Com for 3.1 Billion

The news that HP is to buy 3Com for 3.1 Billion implies a seismic shift in the networking landscape. Cisco will now have to start looking over their shoulders. 

This acquisition has the potential to introduce a serious competitor to the lucrative public sector and corporative markets. Bob Metcalfe who worked in PARC and assisted in the development of Ethernet founded 3COM.
Time will tell if this purchase was worth the money.

Netronome accquire license to develop future generations of Intel 28XXX Network Processors

What was being whispered about has now become reality. Intel are dropping the development of future 28XX network processors and have licensed the technology to Netronome a deep packet inspection startup company. My PhD research focussed on the original NP the IXP 1200. This quirky little chip was a great academic research tool as you had to code all aspects of its execution.
The new breed of 28XX NPs have streamlined some of the development issues. I am not really surprised to see that Netronome plan to focus on builidng in layers 4 – 7 packet inspection. Several papers presented each year at NP conferences tended to intersect with this area. I hope the people I know in Intel who worked on these products are reassigned to useful roles as they are great bunch of talented engineers.

1 million DNS queries per second per CPU product

3C a UK start up has launched an authoritative DNS server that is capable of handling 1 million DNS queries per second per CPU. The product comes in a 1U case and contains two completely separate servers, which provides up to four gigabit Ethernet ports to handle DNS traffic.
The high rate of performance is capable due to the companies proprietary network stack. This network stack is being marketed as a High Performance Network Stack or HPNS. 3C developed the stack so as to add performance to applications such as VoIP, media streaming and DNS. These receive and transmit large numbers of small packets, which is the worst case for most operating systems, and which require context switches from user-mode to kernel and back again for each packet sent or received. According to 3C, HPNS cuts this overhead to a minimum, allowing much higher performance than conventional network stacks.

Cisco accquires a fledgling NP firm

Cisco have announced that they plan to purchase Spanslogic, a 14 person NP firm that was founded in 2004.
According to the Spanslogic website – “We are developing a line of products that challenge long-held assumptions about a fundamental function in computing. Our technology derives from an elegant reformulation of the problem, an insight that allows us to overcome serious bottlenecks related to power consumption, speed, and cost of key applications”
This statement sounds like my Phd abstract, vague but promising. The fact that Cisco use NP technology can come as a surprise to some people. Cisco have been incorporating NP tech into their high end switches for the past few years.
I spoke to a Cisco employee at ANCS 07 conference in San Jose in Dec 07 and he was interested in how my research addresses some of the bottleneck and cost of design issues that face all designers. Cisco may not advertise or market their NP ability, but they have been quietly been designing and using the technology, this in my view speaks volumes.

EuroMicro Component-Based Software Engineering – Call for Papers

EUROMICRO CONFERENCE on Software Engineering and Advanced Applications (SEAA)
Lubeck, Germany, August 27-31, 2007
Submission of papers: March 23rd, 2007
Notification of acceptance: May 3th, 2007
Camera-ready paper due: June 9th, 2007
Component-based software engineering (CBSE) is a development paradigm
that promises to accelerate software development and to reduce costs by
assembling systems from prefabricated software components. Designing,
developing and maintaining components and component-based applications
for reuse is, however, a very complex process, which places high
requirements not only for the component functional and non-functional
properties, but also for the development organization. CBSE covers many
software engineering disciplines and different techniques. Many of them
have been developed and successfully implemented. CBSE has been
successful in certain engineering domains, such as office applications
and distributed internet-based applications but it is still in the early
stage of utilization in many other domains, in particular those which
have specific requirements on different quality attributes.

Those crazy vikings – Joost and how it will work

Wired have a fascinating article on the mad vikings behind Joost and how it will work. The article is indepth and highlights the potential Joost has to shake up the traditional broadcasting business. The same way skype shook up the telcos.

ANCS 06 – Another interesting and successful conference

ANCS 06 drew to a close last Tuesday evening. I am now back at my desk in Ireland and my soul has now caught up with my translocated jet lagged body. It was well worth the trip however. The keynote speakers on both days were excellent, they provided an indepth yet accessible talks on current developments and future tremds.
The various sessions were well organised and the papers presented were interesting and thought provoking. The networking aspect (forgive the pun) was invaluable as it allowed people to put faces to email addresses, and have some meaningful discussions.
As a phd student who is trying to wind up his thesis I found the conference an excellent event, I learned alot about areas outside my sphere of research which is allways a nice thing. Many thanks to Will Eatherton, Patrick Crowley et al.
