Proxy Mobile IPv6 (PMIPv6) is one of the most promising mobility solutions for the next generation wireless networks. PMIPv6 has been recommended for the Third generation partnership project’s (3GPP) Evolved Packet Core (EPC) and has been adopted by the WiMAX forum. However, PMIPv6 in its current state does not attain the stringent handover performance required to support high quality of servic...

Researchers have proposed numerous approaches to providing Quality-of-Service (QoS) across the Internet. The IETF has proposed two reservation approaches: hop-by-hop bandwidth reservation (IntServ); and per-hop behaviour bandwidth reservation (DiffServ). An edge router generates traffic, accepts per-flow reservation and classifies them into predetermined service class; while a core router ensur...

This paper investigates contention resolution schemes for optical packet switching networks from an end-to-end perspective, where the combined exploitation of both core routers and edge routers are highlighted. For the optical-core network, we present the architecture of an optical router to achieve contention resolution in wavelength, time, and space domains. Complementing the solution involvi...

In this paper, we present the Tiny Tera: a small packet switch with an aggregate bandwidth of 320Gb/s. The Tiny Tera is a CMOS-based input-queued, fixed-size packet switch suitable for a wide range of applications such as a highperformance ATM switch, the core of an Internet router or as a fast multiprocessor interconnect. Using off-the-shelf technology, we plan to demonstrate that a very highb...

With the increasing demand for openness, flexibility, and monetization, Network Function Virtualization (NFV) of mobile network functions has become embracing factor most operators. Early reported field deployments virtualized Evolved Packet Core (EPC) - core (CN) component 4G LTE 5G non-standalone networks reflect this growing trend. To best meet requirements power management, load balancing, ...
