Advance Resource Reservation and its Impact on Reservation Protocols
نویسنده
چکیده
To guarantee Quality of Services for continuous media like audio and video, intermediate nodes in networks must be able to reserve resources like buffer capacity, CPU time and bandwidth. Several methods have been introduced to verify that new connections can be accepted by the network without violating guarantees made for already established connections. One drawback of all proposed admission control algorithms is that they accept the reservation only at connection establishment time and it is not possible to reserve the resources in advance. This paper introduces a mechanism for advance reservation of network resources. It further compares the suitability of the proposed Internet reservation protocols ST-2 and RSVP to support this new reservation style.

Design and evaluation of an advance reservation protocol on top of RSVP
Existing reservation protocols such as RSVP implement so-called immediate reservations (ImRe) that are requested and granted just when the resources are actually needed. This paper describes the design, implementation and evaluation of a novel advance reservation protocol. Its major property is that resources are reserved well in advance to the actual usage phase. This way, the probability of r...

This paper studies resource reservation mechanisms that can be incorporated into distributed multi{path Quality{of{Service (QoS) routing algorithms. Three resource reservation schemes, the forward reservation scheme, the backward reservation scheme and the hybrid reservation scheme, are investigated. Protocols that combine these resource reservation schemes with a ticket{based distributed QoS r...

This paper studies resource reservation mechanisms that can be incorporated into distributed multi–path Quality– of–Service (QoS) routing algorithms. Three resource reservation schemes, the forward reservation scheme, the backward reservation scheme and the hybrid reservation scheme, are investigated. Simulations are carried out to compare the performance of the protocols and to study the impac...
متن کاملResource Reservation in Advance in Heterogeneous Networks with Partial ATM Infrastructures
Resource reservation in advance (ReRA) enables scheduling and allocation of resources at an early stage in time. This way, the availability of resources can actually be guaranteed for the point in time when the resources are needed. As opposed to that, current reservation protocols such as RSVP perform an "immediate" reservation without advance scheduling. They can therefore suffer shortage of ...
متن کاملDo We Need Resource Reservation?
Reservation reservation has been a very controversial issue among academic scholars and network operators. This paper examines the question of whether or not the Internet is better off with resource reservation from several aspects. An analytical model shows that reservation-capable networks provide better performance for real-time traffic than that in best-effort-only networks. A study on toda...
