A Web-based design and control system has been investigated for regional optical IP (Internet protocol) networks. The system can design lightpaths connecting nodes such that given traffic is groomed with minimum number of wavelengths, or give a reserve design with additional lightpaths to groom future traffic. Reconfigurable optical add/drop multiplexers (R-OADMs) were also investigated and manufactured...
Network traffic is modeled as Poisson process for analytic simplicity, even though a number of traffic studies have shown that packet interarrivals are not exponentially distributed. Packet arrivals deviate considerably from Poissonity and follow statistical self-similar and long-range dependent behavior (LRD). We propose a novel discrete distribution for the counting process and show that for such...
Providing quality of service (QoS) and traffic engineering capabilities in the next generation multi-service networks is essential, especially to support the requirements of real-time applications. multi-protocol label switching (MPLS) is rapidly emerging technology, which plays a key role in next generation networks by delivering QoS and traffic engineering features. MPLS dramatically improves the...
Telephony services represent an increasing class of applications supported by the current Internet. Due to their cheapest cost, many residential users are adopting VoIP solutions. Therefore, Internet Service Providers need to plan and configure their networks to support services with Quality of Service requirements. In this paper we present a transparent and dynamic approach to the network devices...
