Title

The dual homed DISN core access circuits must be implemented so that each one can support the full bandwidth engineered for the enclave plus additional bandwidth to support surge conditions in time of crisis.

Description

<VulnDiscussion>Providing dual-homed access circuits from a command and control (C2) enclave to the DISN core is useless unless both circuits provide the same capacity to include enough overhead to support surge conditions. If one circuit is lost due to equipment failure or facility damage, the other circuit must be able to carry the entire engineered load for a single circuit servicing the site. Additionally, the engineered capacity must take additional bandwidth into account to support highe...

Fix Text (Documentation Requirement)

Ensure a bandwidth engineering study is performed to determine the WAN bandwidth needs for the site, including surge capacity. Ensure each redundant DISN Core access circuit has the same capacity so that one is able to support the entire engineered bandwidth needs of the enclave.
