Objectives
- Provide delay guaranteed communications service:
The primary objective of NetEx is to provide communication primitives for distributed mission critical applications. Mission critical applications impose stringent requirements on delivering messages by their specified deadlines. It is crucial that the underlying network management can provide such services.
- Be compatible with existing operating systems and network technologies:
Providing delay guarantees is a challenging problem. Some existing solutions call for changes to the OS kernel or network protocols, which may not be cost-effective. NetEx strives to provide delay guarantees on existing OS platforms and networks. Such compatibility makes it easy for NetEx to support many legacy applications.
- Be efficient:
To provide delay-guaranteed communication, various decisions have to be made in connection management and resource allocation. It is imperative to make these decisions as fast as possible because mission critical applications demand a fast response for their requests. This requires minimizing the overhead in the decision making while not compromis ing the quality of service provided.
- Be effective:
NetEx manages network and host resources to support real-time connections. The services provided must be effective in the sense that both the quality-of-service provided to the individual connections and the utilization of system resources should be maximized.
- Be scalable and evolutionary:
Mission critical applications are built on platforms that are subjected to frequent upgrades in terms of size and/or deployment of new devices. The technology we develop should also accommodate the evolution of existing platforms with the addition of new devices. NetEx can thus continue to be effective and efficient while the underlying systems grow in size and extend to heterogeneous domains.
- Be sensitive to mission-specific requirements:
We ought to recognize that different applications have diverse requirements. For a given application, its requirements change as its mode of mission operation changes. To provide services that are consistent with the demands of the application, mission-specific requirements should be properly propagated to the host and network resource managers and correctly taken into account in making decisions on connection admission and resource allocation.
