Thanks for the graph, since you are being transparent can you provide us with additional information that will give us some confidence that KIXP but meet the demands of keeping local traffic local.
- Maximum throughput achievable
Maximum throughput is subject to far too many factors that you need to provide me with specifics i.e between which two points?. If its between two ISPs then its subject to the link capacity they both have to the KIXP. If ISP A has a 10Mbps link to KIXP and ISP B has a 1mbps link to KIXP what do you presume the max throughput will be?. However, the KIXP infrastructure can support in excess of 3Gbps of traffic. Remember its layer 2 switching and nothing else.
- Services allowed to peer
Peering is not IP service based - please refer my previous emails. Peering is based on IP prefixes (using BGP) and not protocols. KIXP provides a layer 2 service and not a layer 3 service.
- Capacity of each member to the exchange point
Let me explain how the KIXP works. Each ISP (peering member) has a router physically located at the KIXP. This router has to interfaces. One interface is connected to the KIXP Switch (ethernet port) the second interface is connected to the infrastructure provider of choice (can be serial,ethernet, fiber etc) and links back to a router located in their respective office/pop. The KIXP Switch port has 3 configurations 10Mbps, 100Mbps and 1Gbps. Each peering member selects their port of choice based on their needs. The same decision is applied when they (each ISP) engage an infrastructure provider to lease the circuit/link back to their respective office/pop Therefore the information on the capacity of each member to the exchange point is information that KIXP may be privy to by virtual of our trust relationship with our members. Its however not information thats KIXP will keep in its records. Consequently, we cannot disclose this information unless we have express permission by our members to do so. Since you have access to the list of members at the KIXP, and are interested to know what the capacity of each members is, please contact them am certain they will be more helpful. On the average the link capacities start from 512Kbps to 1Gbps. We dont have requests for 10Gbps but we are planning on having Switch port support that available in the near future.
- Redundancy in the event of failure
- Power backup is 14hrs (battery system), - backup switches - backup route-servers (each member peers with two route-servers) - redundant cooling - Alternative peering location from primary location Most importantly should the KIXP fail completely since everything is on BGP (a dynamic routing protocol) it defaults to the next best path available to reach the network. Please note that the ISPs links back to their offices will fail often enough. As such, BGP protocol that runs for all members will realise this and converge to the best alternative route without any human interference. The convergence takes place in under 30 seconds. You are welcome to visit the facility to verify this at your convenience.
- Burst capability.
This is not a service that can be provided at layer 2. As a result its not a feature available at KIXP. Regards, Michuki.
