184. The NISP has focused on CIS that are principally static in nature and has given limited consideration to the operation of deployed CIS. The constraints that exist in theatre typically relate to the communications systems (i.e. bandwidth, availability, quality of service) and must be resolved appropriately. The NISP has a part to play in resolving these issues.

185. It is now considered possible that coalition forces may federate their CIS in a deployment so that local autonomous services are provided within the constrained environment. In other words, the coalition forces may interconnect systems or LANs locally “on the ground” forming one or more sub-networks. This would also mean that one nation could be responsible for providing services such as Naming, Addressing and Directory to other nation's systems. In this case each nation's systems would have to conform to additional standards such as CIDR VLSM for sub-netting, DHCP for IP address allocation and LDAP for directory access. This means that local services could be used thus reducing any dependency on premium resources such as long haul communications.
