With advent of access technologies such as WiFi and WiMax, access mechanisms are on the verge of providing continuous access anytime, anywhere and most importantly anyhow. The IEEE 802.16e amendment to the IEEE 802.16 standard adds mobility to the original standard and thus makes WiMax an attractive solution to provide high bit rate mobile wireless services over a broader range of coverage. However,...
The IEEE Standard 802.16 (WiMax) promises to provide wireless broadband access to homes, businesses and core telecommunication networks worldwide. However, security is a key concern to the success of IEEE Standard 802.16. There has been extensive work on improving the security of IEEE Standard 802.16 for both fixed and mobile networks in PMP mode, but thus far there is scarcity of research on security...
This paper provides a current assessment of Carrier Ethernet from a service provider perspective. It highlights the drivers and key attributes of Carrier Ethernet and discusses some remaining gaps and challenges.
There is an emerging wide interest to transition from legacy WAN transport technologies to Ethernet-based technology. The current round of carrier Ethernet standards will successfully equip service providers (SPs) with the required tools to provide carrier-grade scalability and to provision and engineer connection-oriented point-to-point (P2P) packet trunks across a native Ethernet infrastructure...
This paper devises and examines via computer simulation an innovative fully distributed global information- based integrated signaling framework for dynamically provisioning EVCs at any bandwidth granularity including both full wavelength and finer granularity (sub-lambda) EVCs at the optical layer.
