AS29527 Peering Policy

Astutium Ltd operates an Open Peering Policy, through the single global Autonomous System Number AS29527 and macro AS-ASTUTIUM. We are committed to Multi-Lateral Peering Systems (MLPS) and participating in major Public Access Internet Peering Exchanges in each city/country where we have a significant customer presence and physical Point-Of_Presence (POP).

Whenever possible, multiple peering sessions will be implemented with a peer, to reduce/remove the impact of the loss of any single connection/exchange, providing multiple redundant paths for traffic (data) exchange, increasing both parties overall resiliance.

Astutium Ltd considers peering and interconnections a declared service and will accept approaches from industry on that basis, and consents to discussing peering with all players as long as all discussion details remain in the public domain. OTSL does not sign NDAs relating to peering arrangements, as this is deemed not in the best interest of the wider Internet Community.
We believe in both open peering and being open about peering.

Astutium Ltd applies packet/ingress filters on border routers to prevent the injection of packets with spoofed source addresses, malicious traffic, misconfigurations and abuse of network capacity.
It is expected that any peers take similar precautions to protect their own and their peers and downstream customers' networks.

Astutium Ltd reserves the right to discontinue peering with other organisations which do not respond appropriately to reports of network abuse, or which attempts to abuse our network, transit, facilities or staff.


Public Peering Policy

Public Peering takes place at Network Access Points (NAPs) and at both Commercial and Non-Commercial Internet Exchanges (IXs) [preferring Not-for-Profit organisations] .
Astutium Ltd will peer with any company attached to any IX or NAP where OTSL already has a presence, subject to all of the published Peering Criteria being met or exceeded.


Private Peering Policy

Private Peering takes place through private network interconnections (PNIs) that do not traverse a shared/public peering point or the general Internet. Astutium Ltd will peer with any IP-Transit/ADSL/DialUp/Mobile/VoIP service provider in a private peering arrangement, subject to all of the published Peering Criteria being met or exceeded, and where demonstrable traffic levels between peers can justify the peering relationship expenses (routers and cabling costs etc).


Peering Criteria

  • valid public Autonomous System Number (ASN)
  • carrier class router capable of BGP4 and the technical ability in-house to run BGP
  • staffed NOC with technicians available/oncall 24/7/365 to solve problems
  • willing to exchange customer routes and transit customer routes on a settlement-free basis
  • agreement to accept all registered routes, as defined in policy registered with RIPE or other IRRs


Peering AUP/Guidelines

both parties agree to ...
  • provide reasonable effort to minimise the amount of route-flap=
  • agree not to default any traffic to each-others network
  • cooperate on matters of security violations, DoS attacks and similar incidents
  • not to filter packets exchanged based on content
  • maintain reasonable link capacity, agreeing on changes before they are implemented
  • maximum prefix length of 24 bits (/24)


What is Peering

The term PEERING refers to the arrangements between Internet Service Providers (ISPs), Content Providers (CPs) and Transit Providers (TPs) to exchange traffic between their respective networks for transfer on to its final destination.
These peering relationships take the form of either public peering or private peering policies. Well managed peering provides lower latency, better control over traffic flows and implies that there is no single point of failure in transit provisions, providing enough resiliance that any connection or peering loss has minimal impact on customers and traffic levels.
Peering is generally done by the implementation of Border Gateway Protocol (BGP) specifically BGP4, whereby routing information is exchanged by Autonomous Systems Number (ASN).
