Making its way to the disaster area, the radio communication within the newly
combined convoy is suddenly disrupted by a radio jammer. Satellite communication
remains unaffected. The jamming is recognized, reported to the headquarters, and
finally eliminated by an air strike.
The remainder of this paper is organized as follows. Section II will introduce
related work which has been incorporated in the CoNSIS management concept.
Section III will on this basis describe the CoNSIS management concepts, while
section IV and V detail the test setup and the network management experiments
performed in the field test.
II. Related work
The CoNSIS reference model consists of a core network to which user domains
are connected via IPsec crypto devices. The core network itself is composed
of a number of interworking networks operated by different administrative authorities.
Figure 2 shows the main elements of the CoNSIS architecture.

This architecture is close to the Protected Core Network (PCN) [2] approach.
A. Protected Core Networking
In the PCN concept, secure red networks are represented by the Coloured
Clouds (CCs), while the unprotected black network represents the Protected
Core. PCN now requires the existence of certain distinguished nodes, the E-nodes,
in the black network, which ensure availability and offer reliable transport to the CCs.
These routers may be clustered to Protected Core Segments (PCSs) which together
form the PCN. There are certain functionalities like traffic concealment that are
