POLICY FOR DEFENSE DATA NETWORK NODE RELOCATIONS
|
|
|
|
Defense Communications Agency (DCA) letter, dated 24 May 84, provided
|
|
the policy for Defense Data Network (DDN) node relocations. We are
|
|
mindful of the need to relocate communications and ADP equipment to
|
|
accommodate changes and expansions at the local level. However, the
|
|
increasing reliance on DDN by operational systems and the need to
|
|
schedule our relocation resources dictates that we revise our policy
|
|
on node relocation. We request widest dissemination of this policy.
|
|
|
|
One year advance notice of a proposed DDN node relocation is
|
|
required to properly plan, schedule, survey and accomplish the
|
|
relocation. Notice will be provided by the local command/agency via
|
|
formal message to DCA Code B652 (as action addressee) and to all
|
|
intermediate Service Operations and Maintenance (O&M)/Engineering and
|
|
Installation (E&I) commands and associated DDN project offices
|
|
(as information addressees). The message will contain, as a minimum,
|
|
the following information:
|
|
|
|
a. Node name and number.
|
|
|
|
b. Node Site Coordinator: (name, telephone number and electronic
|
|
mail address).
|
|
|
|
c. Current node location: (building, room, address).
|
|
|
|
d. Proposed node location: (building, room, address).
|
|
|
|
e. Date relocation must be completed.
|
|
|
|
f. Reason relocation required: (include impact if not accomplished).
|
|
|
|
g. Telecommunications service actions: (explain, in detail, all
|
|
circuit actions required).
|
|
|
|
h. Proposed schedule: (begin with proposed site survey date and
|
|
show dates, required action and proposed office of primary
|
|
responsibility).
|
|
|
|
DCA may, on a case-by-case basis, be able to make exceptions to
|
|
the one year lead time. Any DCA exception will be accomplished by
|
|
formal correspondence (message or letter) and will be based on the
|
|
complexity of the proposed relocation and required Telecommunications
|
|
Service Request (TSR)/Telecommunications Service Order (TSO) lead
|
|
times in accordance with DCA Circular 310-130-1. For example, a
|
|
shorter lead time may be possible if all actions (except for the actual
|
|
deinstallation/reinstallation of the DDN provided node equipment) can be
|
|
accomplished by the local O&M/E&I organization and only record purpose
|
|
TSR's are required.
|
|
|
|
At no time is the site authorized to move equipment without DCA
|
|
approval and DDN prime contractor support. Normally, a site survey
|
|
will be performed for relocations, with DCA, Service (O&M/E&I) and
|
|
local command participation. Additionally, the requesting organization
|
|
may be required to provide a fund cite to support the cost of DCA/DDN
|
|
survey and E&I support in accordance with DCA message 231613Z Apr 85,
|
|
subject: DDN Node Site Surveys.
|
|
|
|
All organizations supporting DDN node sites are reminded that a node
|
|
relocation will require a DDN node outage with various degrees of
|
|
user and DDN mission impact. For example, the removal of one node
|
|
may result in single thread connectivity for other nodes. Therefore,
|
|
the subsequent outage of an interswitch trunk circuit or node may
|
|
isolate several other nodes and all associated host connections.
|
|
Proper advanced planning will permit DCA and respective organizations
|
|
to minimize the impact of the node relocation. Lack of adequate
|
|
lead time may necessitate DCA directed de-installation and storage
|
|
of the DDN node equipment until re-installation actions can be
|
|
scheduled and accomplished.
|
|
|
|
The office of primary responsibility within DCA for operational node
|
|
relocation requests is the Packet Switch Operations Branch, Code B652,
|
|
(703) 285-5225, (V) 356-5225, DCAB652@DDN1. The office of collateral
|
|
responsibility is the Installation Management Branch, Code B642, (703)
|
|
285-5341, (V) 356-5341, DCAB642@DDN1.
|
|
|
|
This policy has been disseminated as an official DCA message, date-time
|
|
group 181953Z Mar 86, subject as above.
