How Do You Do it?
by Nick Catalano 24 Sep '01

How do most ISPs do their local loops if a building is not ON Net? Colocate with the LEC and run it from their CO? What is the most efficient way of doing it? Also, other than MMFN who else has metro dark-fiber in 20 year IRUs? ---------------------- Nick Catalano Chief Strategy Officer Nozone, Inc Services from the next generation - Nozone, Inc

Re: Points of Failure (was Re: National infrastructure asset)
by Dickson, Brian 24 Sep '01

Even if diversity exists, we need to consider (from an engineering perspective) capacity requirements. Analogy example: FedEx, UPS and others provide huge quantities of shipping, and sustaining the infrastructure growth of the Internet to some substantial degree relies on this capacity. What would the direct and indirect impact of losing the airport at Memphis, or the FedEx sorting facility? Pretty substantial, and long lasting, I'd guess. Similarly, while certain peering locations and relationships have redundancies, the Venn diagrams for union and intersection sets of bilateral peering are non-trivial. It would take a large number of incident locations to affect global route distribution substantially, but only two or three incidents before the impact on available peering capacity (private and public) would be noticable to the general end-user. I think to some degree this should be taken seriously - we should all ask ourselves, does our peering diversity address *capacity* issues sufficiently to handle even one major site outage (eg the power outages at 25 Broadway)? And in considering this, look at each site itself and what the impact of it going away, even temporarily, would be. (Our plans involve going to a large number of neutral colos, for just this reason, among others.) Brian Dickson Velocita Corp.

looking for SLA examples
by Tim Peiffer 23 Sep '01

23 Sep '01

We are looking at putting in contract language surrounding Service Level Agreements and I would like to know what people are doing from the standpoint of latency, packet loss, and bandwidth delivery capability. What examples do people have written in contracts on the above, and what penalties are there for not resolving problems? Example: Service Provider agrees to provide maximum latency guarantees 1) on-net CPE to on-net CPE 60 msec. 2) on-net CPE to off-net peering point 30 msec. 3) End to End 100 msec within the continental US. Remedies for violation of latency guarantee for unresolved latency problems. 1 month 15% off of monthly rate 2 month 25% off of monthly rate 3 month 35% off of monthly rate >3 month customer has option of cancelling remainder of contract. My understanding is that expected latency should be based upon the speed of light in glass 0.6C or roughly 6msec per 1000 fiber route miles plus some amount for router serialization and queuing delays (~5 msec/hop?). What do people use as standard rule of thumb for calculating latency? What do people expect for service level commitments, normal+50% (100?) ?
