As I wrote in my last entry, I'm starting to wonder if getting back into computer networks is a good idea. Based on what I have been reading and some people have been telling me, the industry's not doing that well. Many companies are having trouble, and some are in danger of going under if they're not bought. Just recently, Cisco bought Procket, and now there are rumors that they may be buying Nortel. As layoffs tend to coincide with such events, there will be even more highly qualified people looking for work. (Several friends of mine in the networking area who aren't working have either been laid off or are burned out.) All this will make it even more difficult for me to find a networking job.
It's too bad, because I really like networking. I had a chance to review the first three lecture notes from 6.829, an MIT grad course on computer networks. It really made me feel good to review that material; I felt more like myself (my old self) than I have in quite some time. In the process of reviewing, some other things I had forgotten about networking came back to me. If I give myself time, I think I can bring my skills up to date, but I'm not sure how viable a career in networking is now.
