Exactly how those prefixes are stored and exactly how load-balancing is performed is *very* platform specific, and has tons of variability. I've worked on at least a dozen different hardware based forwarding planes, and not a single pair of them used the same set of data structures and design tradeoffs. Howdy, AFAIK, there are two basic approaches: TCAM and Trie. You can get off in to the weeds fast dealing with how you manage that TCAM or Trie and the Trie-based implementations have all manner of caching strategies to speed them up but the basics go back to TCAM and Trie. TCAM (ternary content addressable memory) is a sort of tri-state SRAM with a special read function. It's organized in rows and each bit in a row is set to 0, 1 or Don't-Care. You organize the routes in that memory in order from most to least specific with the netmask expressed as don't-care bits. You feed the address you want to match in to the TCAM. It's evaluated against every row in parallel during that clock cycle. The TCAM spits out the first matching row. A Trie is a tree data structure organized by bits in the address. Ordinary memory and CPU. Log-nish traversal down to the most specific route. What you expect from a tree. Or have I missed one?

These are the first steps to optimization. Hysteresis is another. They work in ideal cases. However, when coding, we need to consider all cases. How do you set the timer? The timer has to anticipate the future. It's like an automatic transmission. It can't anticipate the future. However, the worst that can happen if the automatic transmission anticipates incorrectly is that it hunts.

Or even process RIB updates as a separate thread, such that the FIB update thread does not try to program every step the RIB might go through. Instead the FIB update thread would take a snapshot of where we are now and where do we want to be and only program the diff. Given the concept is a smaller FIB size, this might actually end up being less FIB programming. Regards, Baldur

IP whitelisting in twitter (the joy of full tunnel VPN)
by Yannis Mitsos 08 Jun '20

08 Jun '20

Hi, We recently flipped from a split to a full tunnel configuration in our firewalls that live inside a big cloud provider. Seems that twitter is rate limiting us because it measures an immense number of API hits from a couple of IPs. Not sure if they have any process to whitelist such VPN endpoints. At least, I couldn't find anything in the web. Does anyone else have similar experience? Is there any colleague from twitter who is willing to reply (publicly or privately). Regards, Yannis

FIB compression comes with some risks. When routes churn, there are certain cases when you have to decompress the FIB. Then, the FIB must have the space, or else OOPS. If a set of compressed routes has to change to decompress some and compress a different set to improve overall compression, there is a lot of FIB programming going on. This can cause very long convergence times. Because a FIB memory cell can not forward and be programmed at the same time, forwarding takes preference and programming speed suffers. FIB programming is the slowest part of convergence, the bottleneck. If routes also have a backup path loaded, then the backup nexthops also need to be the same in order to compress. During convergence, not all routes change at the same time and there could be some very uncompressible transient route sets during convergence. Some possible sequences of compress/decompress during convergence could cause a lot of churn in FIB programming. This presents lots of opportunities for optimization and thus bugs. Regards, Jakob.

It's not like anyone's hiding it. I am sorry as well! I openly admit I am not the smartest bear in the woods. I struggle to read through RFCs. Researching IPv6 for me means doing a web search for "what ipv6 halp", to which google frustratingly returns: No results found for "what ipv6 halp". In all seriousness, I have been trying to understand IPv6 for a long time, and the documentation that I read (again, admittedly not often RFCs, but certainly Wikipedia, linux distro docs, etc) never mentioned DHCP PD, or at least never mentioned it as something important for how end-users would use IPv6. So while it may be true that no one is hiding this information, in my experience no one is shining a spot light on it either, and until I was told about it, I was simply unable to understand IPv6. Once we know something we can forget that everyone else doesn't know that same information, and figuring out what inexperienced people need to know to understand a topic can be difficult. So I am offering to the community that "DHCP PD" is such a thing: it's something that everyone who already knows how things works takes for granted. So when someone points me in the right direction by mentioning such an important piece of the puzzle, I am genuinely grateful! -- Dan

QUIC traffic throttled on AT&T residential
by Daniel Sterling 06 Jun '20

06 Jun '20

I've AT&T fiber (in RTP, NC) (AS7018) and I notice UDP QUIC traffic from google (esp. youtube) becomes very slow after a time. This especially occurs with ipv4 connections. I'm not the only one to notice; a web search for e.g. "Extremely Poor Youtube TV Performance" notes the issue. I assume traffic is being throttled on AT&T's side. And it's not done with their CPE; I'm bypassing their NAT box and connecting my laptop directly to the ONT. A quick google search shows people are aware that QUIC can look like DoS traffic -- but how widely known is this problem? It may become worse if / when sites transition to HTTP/3 For now I reject UDP 443 on the client firewall. Applications using QUIC client libraries then fallback to TCP. This works well and I have no issues with latency or throughput when using TCP. May I naively ask if Google staff are working with AT&T to address this? -- Dan
