10 Gigabit Ethernet Line Cards

Wednesday, May 20th, 2009

180520092929The 10 Gigabit Ethernet (10GE) standard was ratified in 2002, but we finally only got around to installing our first 10GE interface last year. This year, we have another big bunch of 10GE links interconnecting a big bunch of our switches. 10GE still costs a bomb. The Cisco 16-port 10GE line card lists for something like S$80K. Yes, that’s a big sum of money, particularly since the line card on its own is not very useful: You still need a chassis, power supply, fan tray, and supervisor module at the very least.

Linksys WRT610N Dual Band Router

Tuesday, January 6th, 2009

030120091257Last weekend, a Linksys WRT610N became the latest addition to the networking gear I have at home. It replaces my trusty old WRT54G which was starting to go bonkus after serving for many years.

I have been thinking about upgrading my wireless broadband router for some time. In fact, I was considering StarHub’s free Apple Time Capsule promotion last year. It does 802.11N wireless, Gigabit Ethernet wired ports, includes 500GB or 1TB of storage and printer connection sharing.

We’re starting to recruit student helpers again. They will help us run our network and data centre operations. This is like an internship, a program that we’ve run for one semester already. It is a really exciting opportunity for students as they will get hands-on learning experience working with production enterprise networks and data centres.

Bungled Software Upgrade

Wednesday, June 4th, 2008

Software upgrades are usually not terribly complicated things. Of course, the newly upgraded software many introduce new problems, such as incompatibilities or interoperability issues with other software or systems. The same is not too different for firmware upgrades of network switches. They are not trivial (that’s why you need network engineers…), but they are documented procedures that can be and are routinely carried out by network operators and providers.

The Internet’s 25th Birthday Today

Tuesday, January 1st, 2008

Me on my Powerbook G4Yes, the Internet celebrates its 25th birthday today! TCP/IP had a difficult start. It was first demonstrated between Stanford and UCL in 1975. It took quite a bit of persuasion before it was finally adopted and the ARPANET switched over to it on 1 Jan 1983. If you didn’t yet know… TCP/IP is the basic network protocol that drives the modern Internet as we know it today.

If You’re Not American, You’re 3rd Class

Sunday, December 9th, 2007

MyselfSometimes I just can’t help but think that some Americans don’t realize that the world is much larger than their country. The latest episode comes from a DNS report generated by DNSStuff.com which gave a score of “F” for my domain (at work). Why “F”? The scoring methodology and conclusions it tries to draw from the test results are simply and totally illogical. It seems to underscore their presumption that the US is the whole world. If you’re not in the US, then you’re an alien. (I know, I know, as far as their immigration rules are concerned… we are indeed aliens.)
