To provide quality of service guarantees, resource reservation schemes have to maintain reservation states at the nodes along the path of a flow. Advance reservation schemes have to maintain these states for a long period of time. The loss of reservation state caused by node failures, makes advance reservation schemes highly susceptible to node failures. In this paper, we argue that a domain-by...

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...

Light has an important role for oyster mushroom cultivation in order to get optimal growth. The light needed by mushrooms ranges from 150-250 lux. In addition, temperature and humidity also affect the growth of fungi. This research was conducted examine what color spectrum is suitable mushrooms, make automatic control device it easier farmers maintain lighting stability kumbung. system uses LDR...

It is well known that transmission control protocol (TCP) performance degrades severely in IEEE 802.11-based wireless ad hoc networks.We first identify two critical issues leading to the TCP performance degradation: (1) unreliable broadcast, since broadcast frames are transmitted without the request-to-send and clear-to-send (RTS/CTS) dialog and Data/ACK handshake, so they are vulnerable to the...

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...
