Distributed multimedia applications with quality of service requirements that must be guaranteed by the underlying network are evolving at a fast pace. Resource reservation protocols are essential to enable efficient resource management in internetworks. We survey existing resource reservation protocols and the reservation styles they support. Current protocols do not permit different reservati...

In this paper we discuss the need for resource reservation in the Internet and examine some of the strengths and weaknesses of RSVP, which is currently the most popular of Internet reservation protocols that have been developed. We also discuss some alternative reservation protocols for packet networks, in particular the ATM Block Transfer(ABT) reservation protocol that has been designed for us...

As an effective technique for QoS provision, reservation service has been widely applied in various grids. However, plenty of studies have shown that reservation service will bring about many negative effects on system performance, i.e. higher rejection rate and lower resource utilization. To mitigate these negative effects, a relaxed reservation policy is proposed in this paper. It allows grid...

Probabilistic bandwidth guarantees on variable bit-rate network ows o er signi cant improvements in throughput for only modest decreases in guarantee level. In this paper we present a probabilistic bandwidth reservation scheme for variable bit-rate ows called Resource Priority Multiplexing (RPM). The RPM algorithm uses packet marking on edge routers and selective dropping on core routers to pro...

In cloud computing, cloud providers can offer cloud consumers two provisioning plans for computing resources, formal reservation and on-demand plans. Usually, cost of utilizing computing resources provisioned by reservation plan is cheaper than that provisioned by ondemand plan, since cloud consumer has to pay to provider in advance. With the reservation plan(Local Adjustment), the consumer can...

In the paper, author analyzes subject matter of contract for provision services to maintain reserve heat capacity. The notes that capacity is almost only in field supply, definition which not legislation. At same time, this problem covered legal literature. To disclose under study, refers such categories as «power», «heat capacity», «reservation (booking)", «reserve capacity». paper presents pr...

I n this paper, we study a single-product periodic-review inventory system that faces random and price-dependent demand. The firm can purchase the product either from option contracts or from the spot market. Different option contracts are offered by a set of suppliers with a two-part fee structure: a unit reservation cost and a unit exercising cost. The spot market price is random and its real...
