Appendix G -- Data Communications

# Titan/EOS DR Data Communications Architecture

DCSS has installed a [dedicated]{.underline} T1 line between NIH
Building 45 and the SunGard recovery center in Wood Dale, IL. The T1
line terminates at a router at each end and is accessible from the NIH
network, NIHnet. Firewalls and a switch are connected to the Wood Dale
router to provide security protection and segmentation into virtual LANs
(VLANs). The Division of Network Systems and Telecommunications (DNST)
is responsible for the configuration and management of this network
equipment and for contacting the common carrier for any T1 line-related
problems. (These telecommunications services are [not]{.underline} used
for national security emergency preparedness.)

The router in Building 45, and the router, firewalls, and switch in Wood
Dale are continuously active and monitored by DNST. The VLAN ports on
the Wood Dale switch are set in "shut-down" mode when a disaster
recovery is not in progress. Just prior to an NIH disaster recovery test
or in the event of a disaster, SunGard personnel must provide the
physical connection to the SunGard network, and the VLAN ports must be
changed to "no shut-down" mode. When the Wood Dale switch is no longer
required, the VLAN ports must be returned to "shut-down". DNST personnel
can change the settings remotely.

The data communications architecture and configurations are described in
detail in Attachment 4, *DCSS Firewall Maintenance Activity for December
2005*.

## DNST Contact Information

For all support issues, call the DNST Network Operations Center at
301-402-3141 (or 301-506-9069 (pager)).

## TCP/IP Subnet Addresses

The following table lists the disaster recovery IP addresses with host
names, the associated services supported, and indication of the
relationship between disaster recovery IP addresses/host names and NIH
Computer Center IP addresses/host names.

The disaster recovery IP addresses/host names are used for the hot site
tests. In the event of a true disaster, the domain name service (DNS) on
NIHnet needs to be updated to point the production hostnames to the
associated disaster recovery IP addresses. Users would then be able to
access the disaster systems using either set of host names.

## Backup Access to the Disaster Site

Access to the hot site will be via SunGard's Web Redirect services over
the Internet in the case access via the T1 line becomes inoperable. The
IP addresses are assigned at the time of test or disaster; there is no
guarantee that they will be the same from one test to another or to a
disaster. NATing will occur in the firewalls so that the IP addresses of
the hot site host systems remain constant.

Customers will have to be notified of the IP addresses, so they can set
their network configurations appropriately in order to communicate to
the disaster recovery site.

# NIH email Data Communications

DNST has installed redundant high-speed communication links to the NIH
Consolidated Co-Location Site (NCCS). The links are connected to NIHnet
and terminate in two separate buildings on the NIH campus. If the NCCS
site is brought on-line following a Data Center disaster declaration,
users can access their email over NIHnet. If, on the other hand, the
remote Verizon site is brought on-line, users can access their email
over HHSnet which has a dedicated link to the servers located in the
Verizon collocation center.

In the event the networks (NIHnet/HHSnet) and/or links are not working,
users can access their email over the Internet since both alternate
sites have Internet connectivity.
