I’m Being Published!

Posted in General at 10:12 pm by Ian

IEEE/ACM Transactions on Networking has accepted for publication the paper on Virtual Topologies for Multicast Wavelength Division Multiplexed networks that I co-authored the summer between Junior and Senior year.

    Awesome job on the publishing!

    Is there some sort of English translation (at least of the title) that I can read…?

    He he. I’ll break it down.

    A topology is the way things are connected together on a network. Consider the internet. Each computer attaches to an ISP, and each ISP connects to a larger hub. What you get is a sort of fractal branching structure.

    A virtual topology, then, is one that isn’t about the organization of physical links, but about conceptual links. When you go to evilblog.net, there are a dozen or so computers in between you and the webserver, but you don’t care about all that stuff. You have a direct virtual connection to the webserver.

    Multicast means sent to more than one recipient. Traditionally, internet communications are not multicast. It’s one-to-one server to client. Even though a server can connect to many clients, each connection is separate. Cable TV, on the other hand, is multicast. It’s sent out all at once to many clients.

    Multiplexed means mixed signals. A Cable TV network is multiplexed because it’s got lots of channels on one cable.

    Wavelenth Division Multiplexing is one way of splitting up the data pipe. Basically, one data stream is on each wavelength. Cable TV does this as well. The difference here is that Cable uses electrical signals and we were interested in optical signals. Another way to split up the pipe would be Time Division Multiplexing. Instead of having separate wavelengths for the channels and choosing which one to listen to, you could send channel 1 for the first 1/1000th of a second, channel 2 for the second, etc.

    Wow! Congrats to you and your team. Good work you guys. I am a proud, somewhat comprehending parent. A published author or sientific information. Woowee. :-))))

    Congrats! That’s so much cooler than what I’m being published for… writing a review of Scripps. That’s really awesome!

    This is great news–congratulations!
