We propose the demonstration of the RapidNet toolkit for rapid network protocol simulation, implementation and experimentation. RapidNet utilizes declarative networking, a declarative, database-inspired extensible infrastructure that uses query languages to specify behavior. RapidNet integrates a declarative networking engine with the emerging ns-3 network simulator. Our proposed demonstration ...

We present an overview of our group communication system, ChickWeed, for opportunistic networking environments. Opportunistic networking is characterized by sporadic and intermittent connections between wireless devices, such as may arise when embedded devices are carried by humans. ChickWeed is a distributed persistent object store that exploits these connection opportunities through an opport...

In this article, we introduce a new concept for the future information environment, called an “ambient information environment (AmIE).” We first explain it, especially emphasizing the difference from the existing ubiquitous information environment (UbIE), which is an interaction between users and environments. Then, we focus on an ambient networking environment (AmNE) which supports the AmIE as...

In recent years we have seen a fast change in the networking industry: leading by the Software Defined Networking (SDN) paradigm that separates the control plane from the data plane to enable programmability and centralized control of the network infrastructure, the SDN design not only simplifies the network management but also accelerates the innovation speed of deploying advanced network appl...

In the last decade we have witnessed a rapid growth in data center systems, requiring new and highly complex networking devices. The need to refresh networking infrastructure whenever new protocols or functions are introduced, and the increasing costs that this entails, are of a concern to all data center providers. New generations of Systems on Chip (SoC), integrating microprocessors and highe...

In this paper, a hybrid communication paradigm for vehicular networking is presented in which connectivity is provided by both existing network infrastructure (e.g., wireless network access points) through a vehicle-to-infrastructure protocol and traditional vehicle-to-vehicle networking. Preexisting infrastructure can provide seamless connectivity, especially when vehicles are sparse or travel...

Network providers have relied on optical networks as scalable, low-cost, generalpurpose aggregation and transport infrastructures. The emerging communications services environment is placing significant stresses on metro networks, including the aggregation and transport infrastructure. As the existing one evolves to relieve these stresses, it must address three critical challenges: providing si...

This paper considers high-speed networking research from a historical perspective, and in the context of the development of networks. A set of axioms guiding high-speed network research and design are first presented: Ø KNOW THE PAST; I APPLICATION PRIMACY; II HIGH PERFORMANCE PATHS; III LIMITING CONSTRAINTS; IV SYSTEMIC OPTIMISATION. A framework of network generations is used as the basis for ...
