On the Design and Management of Heterogeneous Networks: A Predictability-Based Perspective
While great strides have been made in the design and deployment of commercial networks over the past two decades, relatively little progress has been made toward the realization of large-scale tactical military networks. The primary reasons for this disparity include the fact that commercial telecommunication networks are predominantly wired, relatively stable infrastructures, whereas tactical networks consist largely of wireless mobile nodes with unique operating characteristics in hostile environments.

The integration of various network-level functions, including routing, management, and security, is critical to the efficient operation of a mobile ad hoc network. In this article the authors focus on network mobility (rather than node mobility), implying the movement of entire subnetworks with respect to one another, while individual users initially associated with one such subnetwork may also move to other domains.

In the migration toward network-centric warfare, the NATO STANAG 4406 for Military Message Handling Systems (MMHS) may be used for direct information exchange between high-data-rate strategic users and low-data-rate tactical users by utilizing its new tactical protocol profile. In this article the protocol profiles are tested across a "worst case" tactical HF link providing IP services.

IPv6 extends capabilities of legacy IPv4 networks. The advantages of IPv6, however, come at the cost of increased operational overhead. As government networks providing services to the global information grid (GIG) migrate toward an IPv6-based infrastructure, the implications of an expanded packet header must be analyzed. The authors describe two IPv6 applicable header compression schemes developed by the IETF, and how networks across the GIG infrastructure can adopt them in an effort to reduce IPv6 expanded overhead requirements.
Emre Ertekin and Chris Christou, Booz Allen HamiltonPolicy-Based Dynamic Provision of IP Services in a Secure VPN Coalition Scenario
he authors describe a recent R&D result in supporting secure and dynamic coalition internetworking scenarios, where a number of military and civil subnetworks are combined using IPsec in a higher-level IP secure military network. It is part of the work undertaken in the VPN Workshop initiative, where a set of national defense and research organizations are meeting together to align their vision and requirements on what an IPv4 or IPv6 secure and dynamic IPsec-based virtual private network should be, and how to deploy it in an international multidomain scenario.

A Fault Diagnosis System for the Connected Home
The connected home of the future, in which all consumer appliances in a home are networked together, is close to becoming the connected home of today.

Although text messaging services are becoming increasingly popular in today's global wireless market, fundamental design issues still linger with respect to text entry methods on mobile communication devices.

Elastic buffering is a proxy management technique devised to decouple the multimedia information retrieval rate on the network backbone from the playout streaming rate at the user terminal.

PNNI Routing Congestion Control
There is evidence that link state protocols such as PNNI may not be able to recover from a widespread loss of topology database information or an overload of topology state updates. To prevent this, PNNI extensions have been adopted in the ATM Forum to avoid going into congestion and to recover when congestion occurs.
