This paper studies a traffic grooming in wavelength-division multiplexing (WDM) mesh networks for the SONET/SDH streams requested between node pairs. The traffic could be groomed at the access node before converting to an optical signal carried in the All-Optical network. We design a virtual topology with a given physical topology to satisfy multiple(More)
As Internet business exponentially grows, the need for high security level categories to identify groups of connections or individual transactions is manifest. The development of an efficient and secure communication protocol seems to be highly demanding. In this paper, we propose Adaptive Secure Protocol to support secure ecommerce transactions. Our(More)
In this paper we simplify the 4.4BSD TCP/IP protocol suite, in support of the design and implementation of embedded high performance communication software. Perfonnance is achieved by employing a jlat memory model. The jlat memory model does not require protection between user mode and kernel mode. This model corresponds to the environment of current(More)
We propose a method for dealing with semantic complexities occurring in information retrieval systems on the basis of linguistic observations. Our method follows from an analysis indicating that long runs of content words appear in a stopped document cluster, and our observation that these long runs predominately originate from the prepositional phrase and(More)
When a traffic demand is changed, a virtual topology could be reconfigured to serve that traffic and to retain high performance. We purpose a reconfiguration model that minimizes costly changes in a virtual topology and maximizes network performance for a series of reconfigurations in the long term. The model includes the reconfiguration process and the(More)
