Holiday Weekend Reads (22nov17)

The coming holiday is cutting my publishing schedule short, but I didn’t want to leave too many interesting stories on the cutting room floor. Hence the weekend read comes early this week, and contains a lot more stuff to keep you busy for those couple of extra days. For the long weekend, I have five on security and one on culture. Enjoy!

This first read is about the US government’s collection and maintenance of security vulnerabilities. This is always a tricky topic; if a government knows about security vulnerabilities, there is at least some chance some “bad actor” will, as well. While the government might want to hoard such knowledge, in order to be more effective at breaking into systems, there is at least some possibility that refusing to release information about the vulnerabilities could lead to them not being fixed, and therefore to various systems being comrpomised, resulting in damage to real lives. The US government appears to be rethinking their use and disclosure of vulnerabilities

There can be no doubt that America faces significant risk to our national security and public safety from cyber threats. During the past 25 years, we have moved much of what we value Continue reading

Thoughts on Open/R

Since Facebook has released their Open/R routing platform, there has been a lot of chatter around whether or not it will be a commercial success, whether or not every hyperscaler should use the protocol, whether or not this obsoletes everything in routing before this day in history, etc., etc. I will begin with a single point.

If you haven’t found the tradeoffs, you haven’t looked hard enough.

Design is about tradeoffs. Protocol design is no different than any other design. Hence, we should expect that Open/R makes some tradeoffs. I know this might be surprising to some folks, particularly in the crowd that thinks every new routing system is going to be a silver bullet that solved every problem from the past, that the routing singularity has now occurred, etc. I’ve been in the world of routing since the early 1990’s, perhaps a bit before, and there is one thing I know for certain: if you understand the basics, you would understand there is no routing singularity, and there never will be—at least not until someone produces a quantum wave routing protocol.

Ther reality is you always face one of two choices in routing: build a protocol specifically tuned Continue reading
