Executive Summary This paper discusses the requirements and challenges inherent in the design of a carrier-class network operating system (OS). Key facets of Juniper Networks ® JUNOS ® Software, Juniper's network operating system, are used to illustrate the evolution of OS design and underscore the relationship between functionality and architectural decisions. The challenge of designing a cont...
Sensor networks are specially constructed networks for collecting data from sensor nodes and delivering it to sink nodes at the end. Each nodes in a sensor network are small embedded systems, which require wireless communication among them with limited hardware constraints. If programmers develop sensor network applications for a large-area sensor network, the development of application will be...
The capabilities of a sensor network are strongly influenced by the operating system used on the sensor nodes. In general, two different sensor network operating system types are currently considered: event driven and multi-threaded. It is commonly assumed that event driven operating systems are more suited to sensor networks as they use less memory and processing resources. However, if factors...
The emergence of fast, cheap embedded processors presents the opportunity for processing to occur on the network adapter. We are investigating how a system design incorporating such an intelligent network adapter can be used for applications that benefit from being tightly integrated with the network subsystem. We are developing a safe, extensible operating system, called SPINE, which enables a...
Thesis Network (and grid, if we view grids as networks with specific middleware on top of the component processing node operating systems) programming is an hard task due to the necessity of taking into account network latencies and faults, dynamic node availability and load, performance/efficiency requirements and constrains, etc. Figure 1 Factorizing our long experience in the field of high p...
Today, Windows®-based (and UNIX®-based) PCs have ability to access to the networks at anytime and anyplace. The benefit of such an “always-connected” environment is expanded to non-PC users with new consumer products such as Airboard and CoCoon, which we call the network electronics (or NE) products in this paper. An NE product has nature both of “embedded” and “open-ended,” and partitioned int...
PlanetLab is a geographically distributed overlay network designed to support the evaluation and deployment of planetary-scale network services. Two high-level goals shape its design. First, to enable a large research community to share the infrastructure, PlanetLab provides distributed virtualization, whereby each service runs in an isolated slice of PlanetLab’s global resources. Second, to su...
