Future telecommunications networks will consist of integrated packet-switched (IP and/or ATM), circuit-switched (PSTN) and wireless networks. Service providers will offer a wide portfolio of innovative applications over these integrated networks. Doing so rapidly and efficiently requires open network APIs, with a key API being that for call control as well as coordination and transactions. The ...

TO THE EDITOR: Twenty-five years ago, I faced a situation similar to Jain’s (1). My experience involved a horrid anti-Semite; I was raised with Holocaust survivors. I finally asked my attending to be reassigned. He said that I was a physician and must fulfill my responsibilities to my patient regardless of who and what he was. My personal feelings were immaterial. My attending was right. Jain’s...

In 2010, Jain et al. [JJUW10] provided the first proof that QIP=PSPACE. Jain et al. used a constructive argument which applied the matrix multiplicative weight update method to a semidefinite programming problem formulation of a QMAM protocol to achieve this proof. The proof that QIP= PSPACE was alternately characterized by Xiaodi Wu [Wu10] that same year; Xiaodi Wu’s method, however, was simpl...

Voice in its inherent nature is variable. It is natural to use the VBR class for voice, and transmit voice in its bursty form. On an average, human voice has an speech activity factor of about 42%. This allows us to multiplex a lot of voice sources together. We study the degradation in voice quality under various scheduling policies for VBR voice. Our simulations showed that it is desirable to ...

In this paper, we prove a common fixed point theorem for semi-compatible and weakly compatible mappings in Fuzzy metric space using the property (E.A.) and implicit relation. Our result generalizes the result of Singh and Jain [14].

In a previous contribution we studied the performance of TCP over UBR We showed that TCP perfor mance improves by adding EPD and Fair bu er management techniques over UBR In this contribution we study the e ect of Fast Retransmit and Recovery on these enhancements In general Fast Retransmit and Recovery improves the performance of TCP over UBR However in some cases the performance is degraded T...
