This memo discusses the applicability of "Extensions to RSVP (Resource ReSerVation Protocol) for LSP Tunnels". It highlights the protocol’s principles of operation and describes the network context for which it was designed. Guidelines for deployment are offered and known protocol limitations are indicated. This document is intended to accompany the submission of "Extensions to RSVP for LSP Tun...

A large variety of markets, such as retail markets for gasoline or mortgage markets, are characterized by firms offering a fairly homogenous good produced at virtually the same cost. The present paper provides a theoretical examination of this type of market by developing a sequential search model with incomplete information where consumers are uninformed about the underlying production cost. W...

Only recently Goyal, Olver and Shepherd (Proc. STOC, 2008) proved that the symmetric Virtual Private Network Design (sVPN) problem has the tree routing property, namely, that there always exists an optimal solution to the problem whose support is a tree. Combining this with previous results by Fingerhut, Suri and Turner (J. Alg., 1997) and Gupta, Kleinberg, Kumar, Rastogi and Yener (Proc. STOC,...

We develop a model of sequential search when the cost of searching in each period is stochastic and show that in this setting optimal search entails delay when the cost of searching is high. This characterizes the fact that search activity is often intermittent. Furthermore, we show that if an individual has present-biased preferences this will lead to procrastination, i.e. non-optimal delay th...

In this paper, three dynamic pricing models are developed and analyzed. We assume a limited number of a particular asset is offered for sale over a period of time. This asset is perishable and can be an inventory or a manufacturing capacity. During each period, the seller sets a price for this asset. This price is selected from a predetermined discrete set. The maximum amount which a customer i...

This paper proposes a medium-access control (MAC) protocol for integrated voice/data services in local wireless communications. The proposed protocol is a hybrid of R-Aloha and Aloha reservation adapted to local wireless environment. In the proposed hybrid Aloha-reservation/R-Aloha (HAR) protocol, data messages are transmitted using Aloha-reservation protocol, whereas voice packets are transmit...

This paper explores the need, development of computerized passenger reservation system for Indian railways. The passenger reservation system is based on online transaction processing. It was given the name Integrated Multitrain Passenger REServation System (IMPRESS) which later developed into single image system called Countrywide Network Of Computerized Enhanced ReservaTion (CONCERT). Then thi...
