Issues related to bandwidth assurance in Assured Forwarding based Differentiated Services (Diffserv) networks have been discussed in recent research papers [7][8][11]. Some of the factors that can bias bandwidth assurance are Round Trip Time (RTT), UDP/TCP interaction and different target rates. The bias due to these factors needs to be mitigated before bandwidth assurance for a paying customer...

This paper studies the design and performance of the Probabilistic Priority (PP) [9] packet scheduling algorithm to schedule packets. Unlike an earlier design that uses fractional arithmetic and prohibits large number of classes, we present an integer PP algorithm and show that PP turns out to be a special scheme of applying lottery scheduling [16] to bandwidth allocation in a strict priority s...

We present a new reinforcement learning (RL) approach that enables an autonomous agent to solve decision making problems under constraints. Our assured reinforcement learning approach models the uncertain environment as a high-level, abstract Markov decision process (AMDP), and uses probabilistic model checking to establish AMDP policies that satisfy a set of constraints defined in probabilisti...

The growing number of distributed information systems such as the internet has created a need for security in data sharing. When several autonomous parties attempt to share data, there is not necessarily any guarantee that the participants will share data truthfully. In fact, there is often a large incentive to engage in behavior that can sabotage the effectiveness of such a system. We analyze ...

Most research in network programmability has stressed the exibility engendered by increasing the ability of users to conngure network elements for their own purposes, without addressing the larger issues of how such advanced control systems can coexist both with each other and with more conventional ones. The Tempest framework presented here extends beyond the provision of simple network progra...

Many studies have explored the TCP throughput problem in DiffServ networks. Several new marking schemes have been proposed in order to solve this problem. Even if these marking schemes give good results in the case of per-flow conditioning, they need complex measurements. In this paper we propose a Penalty Shaper (PS) which is able to profile a set of TCP flows so as to improve its conformance ...

Introduction: Supraorbital neuralgia is manifested with pain and tenderness at the distribution of supraorbital nerve (SN). Explicit knowledge location SN vital for clinicians performing regional blocks to relieve pain. In present study, detailed measurements foramen (SOF) notch (SON) South Indian skulls are presented, data compared those from other populations. Methodology: One hundred SON/SOF...
