The objective of the Internet is transparent end-to- end connectivity. Yet, Interconnecting ISPs within Asia and Pacific has been an up hill struggle. If it was cost effective to build a APII, it would have already been built.

POC Barry Raveendran Greene Private Interconnects in Asia Four factors are the primary inhibitors to ISPs interconnecting in Asia and Pacific: Price or International Private Lease Circuits between Asian and Pacific Countries Circuit prices between AP countries have usually been higher than the equivalent circuit to the US. Regional Competition Everyone want to be the regional hub. Multitude of language and cultures Someone who reads and speaks Chinese will not be browsing Hindi content in India. Sustainable Business case which would justify the economics of the interconnection

No true Pan Asian Internet backbone will exist until this problem is addressed. Links between countries in Asia are in general more expensive then the same Mbps link to the US. Links between countries in Asia are in general more expensive then the same Mbps link to the US. $ $ $ $ $ Result: Asian ISPs use the US West Cost as the hub because it is more cost effective - despite the performance impact of crossing the Pacific Ocean twice!

It is a a minute subset of existing bi-lateral telephony interconnection technique and applying it to interconnection ISPs in Asia. It mitigates some of the effects of the high inter-country bandwidth cost in Asia. It is a technique that works. AP Mesh

POC Barry Raveendran Greene Private Interconnects in Asia AP Mesh A informal Internet Backbone effort informally launched by KDD and SingTel in 1996 Based off comprehensive analysis of profit margins of existing services that use backbones in the region (X.25, TCP/IP, Frame Relay, FAX, and IDD Voice). Took the best of the international telephony network’s bi-lateral arrangements to construct a flexible model of building a scaleable backbone based on proven success. Build bi-lateral business cases for interconnection between major Telcos in the region - similar to IDD Voice Interconnect. AP Mesh

Hence, backbone link is gradually upgraded when real bandwidth requirements exist. Performance increases from the latency reduction compensate for the gradual increase of bandwidth. Stack services on top of the link basic interconnect agreement. Examples: VPNRoamingOSS Web Co-location Proxy/Cache USENET News VoIPVideo Conferencing AP Mesh Dated The 1996 List

Each party can compete with each other as a regional Internet Hub while enjoying the benefits of mutual collaboration. Result - Regional interconnection at a faction of the cost!

Each party monitors the link with SNMP. When the average utilization reaches a agreed threshold, the circuit is upgraded. Private Interconnects in Asia ISP Threshold Upgrade AP Mesh

11 © 2006 Cisco Systems, Inc. All rights reserved. POC Barry Raveendran Greene Principle #3 - Upgrades are incremental Typically, 128 Kbps is used to start the relationship. As the traffic pattern and trends are established, automatic incremental upgrade will take the circuit from 128Kbps to 256 Kbps, to 512 Kbps, to 2 Mbps, etc. Private Interconnects in Asia ISP Threshold AP Mesh

Allow three links to be configured (via BGP) for mutual backup. More cost effective way of providing redundancy vs the old PSTN circuit stand-by technique.

Example - VPNs Each party can sell VPN services with or without the cooperation of the partner. With cooperation, service level agreements an premium services can be offered.

With the AP Mesh peering technique, ISPs and Telcos can have a wide range of regional connectivity and be perceived as the regional hub …. from their point of view ….. For example, Hong Kong Telecom, KDD, Singapore Telecom, and Telstra all appear the be the regional hub - from their point of view. AP Mesh
