Accretive Networks Bi-Lateral Peering Policy
			Effective August 1st, 2001


Peering:
Accretive Networks has an open peering policy and will, at its sole
discretion, peer with any IP service provider. These peering relationships
take the form of 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. Whenever
possible, Accretive Networks will strive to implement multiple peering 
sessions with a peer, to diminish the impact of the loss of a single 
connection.

General Guidelines:
*Both parties agree to maintain a capable Network Operations Center, 
  staffed 24/7/365
*Both parties agree to accept a maximum prefix length of 24 bits. Aggregation 
  of routing information will be done where possible and technically 
  feasible.
*Both parties agree to accept all registered routes, as defined in policy
  registered with appropriate IRRs (RADB, RIPE, APNIC, JNIC). Whenever
  possible, a AS-set macro shall be used (AS-ACCRETIVE).
*Accretive Networks 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.
*Accretive Networks reserves the right to implement packet filters on its border
  routers to protect Accretive 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.
*Both parties agree 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.
*Both parties agree to not filter packets exchanged based on content.
*Both parties agree to honor MEDs when peering at geographically disperse 
  locations.
*Both parties agree to actively cooperate chasing security violations, 
  DoS attacks, and similar incidents.
*Both parties agree that participation in the agreement is voluntary, and 
  on a settlement-free basis. This agreement is implemented by each party 
  on a best-effort basis.
*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.
*Exchange of routing information will be performed using BGP4 or other 
  appropriate exterior routing protocol, as determined by the IETF.
*Both parties agree to provide reasonable effort to minimize the amount 
  of route-flap.
*Both parties agree that turnup of a peering session between Accretive 
  Networks and PEER constitutes acceptance of this agreement.
