Peering Policy


I. Definitions

Peering. Peering is the settlement free exchange of IP traffic between two interconnected IP networks. This exchange is strictly limited to traffic destined for the other network. Traffic is exchanged on a bilateral basis between peering routers and is governed by BGP-4 peering sessions.

National peering. Peering with the other network offering services in the Czech Republic or in Slovakia

International peering. Peering with the other network offering services in other countries.

Transit. Indicates a settlement based customer/provider relationship between networks, where one network uses the other network to provide upstream connectivity.

Route announcement. The means by which two peering partners notify each other of address information in order for the peering partners to exchange Internet traffic. The current means is by the BGP-4 protocol.

Network. A network or Autonomous System (AS) is defined as a group of connected Internet Protocol (IP) routers that are under one administrative control.

II. General Conditions & Requirements

  1. We require you to demonstrate a competence in BGP and TCP/IP networking.
  2. We require you to maintain an english, czech or slovak speaking NOC able to respond to issues by email and telephone 24x7. You agree we can check for accessibility of your NOC everytime.
  3. You shall register routes and routing policy with a Dial Telecom recognised Internet routing registry, i.e. RIPE, APNIC, or RADB. Directly from your AS you shall announce only those registered routes.
  4. You shall not send us prefixes from the RFC 1918 address range considered for private use nor any other prefixes from address range considered for intra-AS or other specific usage in relevant RFC documents, for example RFC 990, RFC 1700, RFC 2544, RFC 3068, RFC 3927, RFC 5736, RFC 5737, RFC 5771, RFC 6052, RFC 6598, RFC 6666 and RFC 6890.
  5. You will send us only aggregated prefixes (i.e. you will not send us fifty small prefixes instead of one big).
  6. You shall not establish a route of last resort, i.e. default route, or any other static routes directed to Dial Telecom.
  7. You shall see to that the peering interconnection is always the best-preferred path between the both networks, unless other is stated in an agreement.
  8. We will accept any routes people send us, as long as this does not cause operational problems (i.e. if you send us full routing, we will use you for transit).
  9. If the peering is established through public interchange points, the applicant will establish peering sessions in every public interchange point where applicant's network and Dial Telecom network are presented.
  10. You will accept hot-potato routing from us as we will accept hot-potato routing from you (i.e. we do not have to honor MEDs) unless otherwise negotiated.
  11. We do not require a formal peering agreement, but will sign one, subject to negotiation, if you require one.
  12. Each peering connection speed shall be at least 10 Gbps.
  13. You can apply for peering using e-mail address peering[at]dialtelecom.cz.
  14. There is not any claim on peering with us although you comply these peering policy.
  15. This version of Dial Telecom peering policy is valid from 31st December 2007

III. Specific conditions for settlement-free national peerings

  1. Dial Telecom will not enter into peering relationship with customers of existing peering partners.
  2. Dial Telecom may shutdown peering if peer is a customer of existing peering partner.
  3. Your peak traffic ratio shall be 1:2 or smaller.
  4. If you don't comply these policies, you can apply for a paid peering.
