- MANAGEMENT BULLETIN
-
- The DDN MANAGEMENT BULLETIN is distributed online by the DDN Network
- Information Center under DCA contract as a means of communicating
- official policy, procedures and other information of concern to
- management personnel at DDN facilities. Back issues may be read
- through the TACNEWS server ("@n" command at the TAC) or may be
- obtained by FTP from the SRI-NIC host [26.0.0.73 or 10.0.0.51] using
- userid="anonymous" and password="guest". The filename format for
- bulletins is DDN-NEWS:DDN-MGT-BULLETIN-nn.TXT (where "nn" is the
- bulletin number).

- 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.
