Are you on the Extreme half of the LINX network or on the Brocade side?

What I think is ironic is that I was just sitting down to study for my upcoming Cisco BGP test and wanted to quickly check and see if the latest QEN was out and found this instead.

This is doublely great because when my wife yelled at me asking if I was playing Eve instead of studing I said, nope I am studying.




For anyone studying BGP, I highly recommend "Internet Routing Architectures" by Sam Halabi now in it's 2nd Edition. It's one of the best written technical publications I've read.

Backtrace: It uses udp traceroutes, and yes, some networks will drop the probe packet/not send an ICMP unreachable. It does not necessarily prevent the FCP from optimizing the route. Probes are used to evaluate the performance of the alternate available paths, it doesn't matter if the end host drops the probe packet. There is still enough information gathered about the available connections to make a good route decision.

The initial performance measurement was gathered passively, on CCP's network.

I have been reading this, it is infact one of the better written books. I already have my CCNP, CCDP, and I re-certed the last time with the QoS test so this time around I figured what the hell, you're only 2 tests away from a CCIP. The odd part is the CCNP Voice would be way more usefult because I deal with the the Unified Communications products on a daily basis and nearly never with BGP.

I enjoy routing and switching much more because you have to think like the device to make it forward traffic the way you want it, and I seem to have a much better knack for that. I'd love to work on engineering traffic, but where I live there is like nearly zero demand for people who know how to do it.

Sexy, I approve of this devblog.

I for one welcome our TCP overlords.

I'd have to look up the product literature, but it sounds like FCP dynamically decides which networks to announce via what interfaces. As long as the interval that it can choose to change announcements is large enough, I think it sounds like a good solution. BGP does not do quick, dynamic changes well.

NB: The exception to the rule of "Tier 1 ISPs don't pay for connections, others pay them" is when they are connecting to other tier 1 ISPs. The assumption there is that the traffic from another tier 1 will be more or less balanced with the traffic coming from the other side of the connection that tier 1 ISPs don't charge each other. The problem comes in when a tier 1 ISP decides that another company is no longer a tier 1 ISP and wants to charge them...

I assume it's not possible for the end-user (or the game client) to force a specific route?


No, you cannot. Routing between ASs is controlled by the AS path, and as an end user, you have no control of that. There are only 65000 unique AS numbers for the entire Internet (65000 - 65535 are like the 192.168.x.y IP addresses, they are not supposed to be publically routable), so for CCP to have its own is quite something.

I agree, experienced in this area :)
