Division 4.7 Resiliency

United Kingdom

Original text. Later amendments are not shown.

The CS-SIS has been designed with high availability as a requirement. For this reason the system have integrated resiliency against component malfunctions by duplicating all equipment.

The components of the Communication Infrastructure must also be resilient against component failure. For the Communication Infrastructure, it means that the following components must be resilient:

  • backbone network

  • routing devices

  • points of presence

  • local loop connections (including physically redundant cabling)

  • security devices (crypto devices, firewalls, etc.)

  • all generic services (DNS, NTP, etc.)

  • LNI/BLNI.

The failover mechanisms for all network equipment should occur without any manual intervention.
