CHT-I IP Network (TWGate) Peering Policy

Effective December 1, 2002/11/25

Peering:

CHT-I IP Network has an open peering policy and will, at its sole discretion, peer with any IP service provider. These peering relationships take the form for either public or private peering. Public peering takes place at Network Access Points (NAPs) and Commercial Internet Exchanges, while private peering takes place through private network interconnections (PNIs) that do not traverse a [shared] public peering point. Also a bilateral submarine within Asia-Pacific will be available to build a direct private peering to Taiwan.

General Guidelines:

l CHT-I’s IP Network Policy as follows:

n Applies ingress filters towards its customers, which prevent the injection of packets with spoofed source addresses. It is expected that PEER take similar precautions to protect its own and their peers’ networks.

n Reserves the right to implement packet filters on its border routers to protect CHT-I IP Network customers from malicious traffic, misconfiguration, and abuse of network capacity. At the time of this writing, traffic to a few TCP ports and UDP ports in the “well known” range are blocked at network ingress points.

n Exchange of routing information will be performed using BGP4 or other appropriate exterior routing protocol, as determined by the IETF.

l We are inviting PEER to agree follows items:

n To maintain a capable Network Operations Center, staffed 24/7/365.

n To accept a maximum prefix length of 24 bits. Aggregation of routing information will be done where possible and technically feasible.

n To accept all registered routes, as defined in policy registered with appropriate IRRs (RADB, RIPE, APNIC, JNIC). Whenever possible, an AS-set macro shall be used (AS-ACCRETIVE).

n To maintain a reasonable link capacity. If there is a need for capacity modification (more or less), both parties will agree on changes before they are implemented.

n Not to filter packets exchanged based on content.

n To honor MEDs when peering at geographically disperse locations.

n To activity cooperate chasing security violations, DoS attacks, and similar incidents.

n Participation in the agreement is voluntary, and on a settlement-free basis. This agreement is implemented by each party on a best-effort basis.

n To provide reasonable effort to minimize the amount of route-flap.

n To turn up of a peering session between CHT-I IP Network and PEER constitutes acceptance of this agreement.

Terminate:

l Either party has the right to withdraw or change the peering policy at any time. 30 days notice of such withdrawal or changes will be given, in writing.
