This paper presents Haggle, an architecture for mobile devices that enables seamless network connectivity and application functionality in dynamic mobile environments. Current applications must contain significant network binding and protocol logic, which makes them inflexible to the dynamic networking environments facing mobile devices. Haggle allows separating application logic from transport...

The demands on metropolitan wireless networks is likely to change dramatically over the coming years due to the emergence of new applications and devices. The network infrastructure will need to adapt to meet these changing demands. In order to design the future infrastructure, we must first understand these workload trends and the applications that create them. In this white paper, we focus on...

This paper presents an application layer active networking infrastructure for distributed virtual reality. It will assess the efficiency for group communication of multicast trees over n-way distribution. The analysis of clock synchronisation and event routing is also performed. The viability of this infrastructure is assessed by simulation.

Future space mission concepts and designs pose many networking challenges for command, telemetry, and science data applications with diverse end-to-end data delivery needs. For future end-to-end architecture designs, a key challenge is meeting expected application quality of service requirements for multiple simultaneous mission data flows with options to use diverse onboard local data buses, c...

Preface Wireless networking today is the challenging problem of networked systems. The issues of tenuous connectivity, limited processing capacity, batteries, and on-the-move operation increases the complexity of achieving robust communications. At the same time, there is great demand for this technology. Personal schedules change on a day-today and hour-to-hour basis and people increasingly ne...

Enterprise social networking (ESN) is a relatively new phenomenon and not yet fully understood. An important reason for this lies in the fact that ESN are built on malleable technologies that do not lend themselves to immediate forms of workplace usage determined or prescribed by their features. Rather, their potential only manifests when people make sense of and incorporate them into their day...

GENI brings together a wide variety of heterogeneous networking infrastructure and technologies under a common platform. We propose programming exercises for graduate students to introduce GENI and enable students to conduct high fidelity networking experiments. In this paper, we focus on an exercise to study congestion control and reliability using the ProtoGENI aggregate. A planned second exe...

The future of networking is to move to an entirely optical infrastructure. Several leading National Research Networking organizations are creating test-beds to pilot the new paradigm. This paper explores some thoughts about the different usage models of optical networks. Different classes of users are identified. The services, required by the Internet traffic from those different classes of use...

The CPS networking infrastructure is comprised of an Ethernet based frontend fabric and an RDMA enabled storage backend fabric, which utilizes the SMB Direct protocol for high efficiency, high performance storage networking. The SMB Direct protocol enables high throughput, low latency and high efficiency storage, and unprecedented performance in virtual machine mobility. Native system software ...

Any advancement in new technologies requires a reliable and affordable networking infrastructure. The network performance can be expressed by several metrics such as throughput, delay and packet loss. Many networking protocols, standards and technologies were developed without full and thorough examination of the underlying performance metrics. One major metrics is the packet loss as it affects...
