Cairo Internet eXchange Policies


Basic principles

  • CAIX administration team is responsible for the administration of the IX and determines policies relating to the IX.
  • Telecom Egypt provides resources essential to the operation of the CAIX facility, including power, air-conditioning and secure access to the site. CAIX administration team maintains the switches and router at CAIX gear. CAIX is currently hosted by Telecom Egypt in Ramses CO.
  • Each CAIX member is responsible for obtaining one or more links to CAIX facility, and for all costs associated with those links. CAIX members are also responsible for supplying any equipment, such as routers, they require to connect their networks to the CAIX switch.
  • There is no restriction on number of lines a member may terminate at the CAIX, provided that they comply with all of CAIX policies.


  • There is no joining fee for CAIX.
  • Local ISP must hold Class A or Class B License from NTRA to become a CAIX member.
  • Content providers and service providers (such as DNS service) could become members in CAIX upon ratifying from CAIX management.
  • Content providers and service providers to host their servers in Telecom Egypt central office where CAIX is located, should pay hosting fees to Telecom Egypt based on bilateral agreement with Telecom Egypt.
  • The hosting fees may be waived for servers used for hosted services (such as DNS servers) located at CAIX gear. The CAIX management remains responsible for determining which services it is appropriate to be hosted at CAIX, and when hosting fees should be waived.

Allocation of scarce resources

  • CAIX administration team notes that ideally, there will be sufficient ports and other resources to meet all of the demands of members of the IX. However, in practice there may be a scarcity of a particular resource at an IX. In this case, the following policies on the allocation of scarce resources apply.
  • The CAIX administration team will allocate scarce resources primarily on the basis of demonstrated use. CAIX members requesting scarce resources may request an allocation above that required for demonstrated use, but in such a case, the CAIX administration team has the right to reclaim under-utilized resources if they are needed for another CAIX member with demonstrated use. If a scarce resource is reclaimed from any CAIX member, once the resource ceases to become scarce, that member’s access to that resource should be prioritized.
  • In the case of a dispute in the allocation of a scarce resource, the matter will be put to all CAIX members for voting, with one vote per member.

Requirement to exchange traffic via CAIX switch fabric

  • All interconnection at CAIX must take place via CAIX switch fabric. This means that within CAIX gear there will be no direct peer-to-peer interconnection between ISPs or between content provider or service provider and ISP, and all traffic exchanged must be via CAIX switch.
  • All members must peer with CAIX router whether using IPv4 or IPv6.
  • All members must advertise all local IP routes they have in their routing tables to CAIX router.
  • Local IP routes will be filtered by CAIX router based on AS number.
  • All IP routes must advertised to CAIX router with LOCAL-PREFERENCE equal to 120
  • All IP routes must advertised to CAIX in more specific prefix form.
  • Traffic exchanges among CAIX members within CAIX switches on a no-charge basis.
  • CAIX administration team retains the right to grant exceptions to the above clauses, where technically necessary.

Rack space

  • ontent providers and service providers not allowed to co-locate their servers in CAIX rack, and in order to co-locate their servers in racks adjacent to CAIX rack, they must sign a bilateral agreement with Telecom Egypt for co-location or with one of CAIX members. CAIX administration team may grant exceptions to this rule on case-by-case basis.
  • All equipment hosted at the CAIX must be rack-mounted. CAIX administration team reserves the right to disconnect any equipment which is not rack-mounted. CAIX administration team may grant exceptions to this rule on case-by-case basis.
  • The above policies on rack space are intended to ensure that CAIX remains an Internet exchange, and not an equipment hosting facility.
  • CAIX rack space allocations are not transferable. CAIX members in case of hosting their servers in CAIX rack may not resell, sublet or give away rack space without permission from CAIX management.


  • The CAIX administration team will not be responsible for all Ethernet patch cabling to CAIX facility. CAIX members are responsible to supply their own Ethernet cabling. These rules are subject to the discretion of the CAIX administration team.
  • For transparency and fairness, the CAIX administration team will help members in deploying cables and in selecting the best shortest path to CAIX facility.

Hosting of servers

  • No servers or other non-standard equipment may be hosted at CAIX rack without the explicit permission of the CAIX administration team. Any requests to host third party equipment (e.g. monitoring devices) will be dealt with by the CAIX administration team on a case-by-case basis.

SNMP access

  • No CAIX member may have access to the community string for the CAIX switches unless cleared to do so by the CAIX management.


  • Members are responsible for the insurance of their own equipment.

Liability for outages

  • CAIX members using the CAIX gear cannot hold CAIX team or other CAIX members liable for network outages of any kind.


  • CAIX administration team reserves the right to terminate any CAIX member’s access to CAIX gear for non-compliance with CAIX policies.

Changes to this policy

  • CAIX administration team and management reserves the right to make changes to its CAIX policies, following due consultation with CAIX members
