Peering Disputes Migrate To IPv6

1sockchuck writes "As more networks prepare for the transition to IPv6, we're seeing the first peering disputes (sometimes known as 'Internet partitions') involving IPv6 connectivity. The dispute involves Cogent, which has previously been involved in high-profile IPv4 peering spats with Sprint, Level 3 and Telia. Hurricane Electric, which has been an early adopter on IPv6, says Cogent won't peer with it over IPv6. Hurricane has extended an olive branch by baking a cake bearing a message of outreach for Cogent."

      Peering is generally only considered "fair" if there is a similar flow of traffic in each direction (averaged over a good period of time). Peering agreements are written with certain traffic ratios defined, and going outside those ratios terminates the agreement or triggers a payment clause. It appears that in every case, Cogent traffic had dropped outside of the contract ratios, and so they were asked to pay for service like anyone else (as it was no longer an equitable peering), and instead they threw a public tantrum and blamed everybody else.

      The details are never made public, so when it happens once, you don't really know who is telling the truth. When it happens over and over again with one provider, as with Cogent, a picture begins to form. Cogent is a "tier-1" wanna-be, but don't have the traffic to back it up.

BigPornSite will hand off their traffic to SuperCheapISP in the west-coast data center, and SuperCheapISP will route the traffic to the viewer's ISP. (Let's say its Comcast...)

      So, SuperCheapISP got paid by the porn site to route the traffic for maybe 100m or so, and gets rid of it as soon as they can. Would you want to sign a peering agreement with them, knowing that they're going to dump tons of traffic on your network with no regards to where its actually going?

      Network traffic tends to be bursty, this means that even with "no congestion issues", there will be queued traffic during the bursts, it just averages out over short periods of time. QoS can be important in these cases since it allows you to move traffic for applications that are adversely affected by latency to the front of the queue. On a network with adequate capacity, the result of this is that things like VoIP work better because the latency stays very low all the time, whilst things like bittorrent get variable latency (which doesn't affect the raw throughput, so no one will notice).

      Of course, there are always times when even the most well provisioned network gets congested (e.g. if a good number of connections get chopped then the remaining parts of the network come under increased load. A good example of this is in the case of natural (or not so natural) disasters where not only have you lost a lot of the network, but the world and his dog is on the web trying to get news updates.

      QoS isn't without issues though - one of which is trying to identify which traffic to prioritise.

      Basically, different companies own and operate the physical cables, and they charge for use. To provide their own clients with access to other parts of the internet in principle they would have to buy bandwidth from their competitors, but rather than do this, the network owners often make agreements to pass on data for each other free of charge.

  15. Seen before with Cogent/Sprint by mjensen · · Score: 5, Informative

    The following is copied from a previous Cogent/Spint debacle posting:

    Just like what happened with Level(3) a few years ago.

    Cogent's history in the ISP market has been absolutely horrible. They came in to town as the Walmart of ISPs, investing in a huge new super-efficient backbone infrastructure doing everything it could to cut costs so they could offer insane deals to their customers. They were running 10Gigabit connections using existing fiber and brand new equipment. They had no 'legacy' hardware.

    The hosting industry bit into the Cogent game when they had customers running multimedia sites that needed tons of bandwidth (see: porn) and were tired of paying insane rates per mbps when Cogent had this brand new network with tons of capacity.

    But Cogent wasn't in the 'settlement free interconnect' game yet, they were paying for bandwidth themselves. So they went out and purchased a few ISPs that already had settlement free interconnects. The agreements are already in place, so it was a big win situation for them. But these agreements almost always come with the term that you must give as much as you receive (so you need to have a balance between hosted sites and end users.) Cogent didn't have end users, they had servers.

    Think of it this way: I am an apartment complex and I have an agreement to mow my neighbor's lawn and in exchange he shovels my sidewalk. It uses approximately the same amount of work. Now imagine my neighbor and all of his agreements are bought by the local golf course. Now the golf course now expects me to mow the entire course because the agreement was that they would shovel and I would mow. Cogent was the golf course, I am an ISP.

    Now in my apartment I house a bunch of golfers once I say "screw this, figure out your lawn situation yourself" the course says "ok, well, I guess your tenants are going to have to go without golf." What the hell am I to do now? Mow this golf course to keep my tenants happy?

    Finally I come to an agreement, the golf course has to pay me a small amount and I will mow their grass. Everything seems OK, but then the golf course gets in to a bit of trouble and all of a sudden decides "OK, well... he doesn't want his tenants to go without golf so he will probably keep mowing our grass even if we stop paying him." Here we are again, I'm in an impossible situation because I really care about my tenants but man, I just cannot mow an entire golf course all by myself. So I send the golf course warnings after warnings, and after I reach a tipping point I just say "GFY, I'm not mowing your course anymore." I stop mowing it, and the golf course says "IT IS TOTALLY HIS FAULT THAT YOU CANNOT PLAY GOLF!!!"

    Right now a lot of ISPs can hit Cogent's old pricing (and Cogent just cannot go any lower than they already are) so a lot if ISPs will just pass on Cogent and go for someone with a better record.

    There is a lot more to the story that we don't know about, and since these agreements are generally done under a NDA we will never know for sure what exactly is happening at Cogent.

    Just a FYI: I work for a hosting company that has had some dealings with Cogent in the past.

      The analogy doesn't work though, because no matter how much traffic there is or how unbalanced it may be, every last bit of it represents a peer on one network that has paid for connectivity with the other network. Every meg Cogent shoveled through the peering point only went there because a customer of the other network wanted his porn from a server on Cogent's network.

      I won't say that Cogent is in any way, shape or form perfect. They could stand to improve a LOT in many areas. But then, the same is true of every transit provider.

      The problem is hot-potato routing, and the fact that cogent (anyone, really) will push that traffic out of their network and into someone else's over the peering point as soon as possible.

      If they held the packet for as much as they possible could in their network, the tale would be different. But that's not easy to do, and generally not done anyway except in very, VERY specific situations.

      So, the peering agreements among such networks really have to try to strike a balance of in/out traffic, and either terminate the peering or require compensation from the party that PRODUCES most of the traffic to the one that has to RECEIVE most of that traffic. It *really* is all about hot-potato routing.

      They could apply that infinite amount of expertise they all tell their customers they have and announce correct route costs and only announce reasonable routes through the peering points.

      Hot potato routing depends on the 'victim' using dumb-as-a-brick routing plans.

      Of course the lack of appropriate route plans and peering costs everyone. I have seen some routes for my own traffic that make no sense whatsoever for either party.

      Case in point, going from my home to a particular geographically close server. the traffic passed through 56 Marietta (a telco hotel w/ a meet-me room), up to Virginia and accross the peering point, BACK to a different router at 56 Marietta and then to the datacenter. I happen to know that the two routers at 56 both had ports open and could easily have been connected by a 5m Cat6.

      Instead both sides carried the traffic a few hundred extra miles on a long haul fiber. They could well have been different channels in the same cable.
