....require modifications to switches or extra NICs on hosts. FM QoS [19] provides predictable performance by devising conflict free communication schedules. In [20] and [21] the authors propose new hardware or hardware software infrastructures to support QoS. The Globus project s GARA framework [22,23] provides end to end QoS for different types of resources. 8. Conclusions and Future Work We have presented a QoS framework for supporting applications in clusters with resource adaptivity and predictable execution performance. The framework uses a NIC based rate control mechanism. Experimental ....

....bursty, such as event based simulations, although other QoS requirements are important such as delay. Substantial work within the context of Globus, in particular the Gara project [44] has demonstrated the importance of QoS through both network and processor resource management and reservation [45]. However the architectures supporting these features are highly centralized and require large amounts of information to be stored locally (e.g. network slot tables) These systems are thus hard to scale and have several single points of failure. The approach described here demonstrates a system ....

....Fig. 1. Ten Steps for Superscheduling. Another document that is in the final review process is the Advance Reservation APT , by A. Roy and V. Sander [6] This document defines an experimental APT for quality of service reservations for different types of resources. It is strongly based on GARA [7]. This document is in final stages of review. The active working group, Scheduling Attributes [8] led by U. Schwiegelshohn and R. Yahyapour, is defining a set of attributes of lower level scheduling instances that can be used to make resource management decisions by higher level schedulers. The ....

....required, which controls incoming traffic and which further on allows for billing. Such an admission control can be implemented by an automated DS network management based on a centralized entity called Bandwidth Broker [22] The General purpose Architecture for Reservation and Allocation (GARA) [16, 17, 23, 24] implements an advance reservation framework. GARA includes a DS reservation manager, which allows to use it as a Bandwidth Broker for Grid applications. Current work allows to extend admission control functions by means of Network Calculus such that quantifiable QoS guarantees like delay bounds ....

....at the DS domains ingress. Similar problems do arise, if the required Guaranteed Rate Service is implemented based on the AF PHB. Here excess traffic is not discarded at the ingress of the domain, but marked Red and probably discarded in the domains core, yet reducing TCP performance, too. In [15, 23, 24] it is shown that the mean rate of a TCP connection can be significantly reduced in a guaranteed rate environment, if the rate at which the TCP sender injects packets into the network temporarily exceeds the guaranteed rate such that packet drops can occur. Shaping of TCP streams at the target ....

....forecasts. One of the NWS sensors is the network sensor [13] whose aim is to take measurements that represent the network quality in term of latency and bandwidth. The di erent components of the NWS are distributed on monitored hosts. The GARA (Globus Architecture for Reservation and Allocation) [12] provides advance reservations and end to end management for quality of service on di erent types of resources (network, storage and computing) This architecture remains a traditional solution, in the sense that the processing task associated with transport purpose are performed on the end ....

....are shared among many simultaneous users, meaning that resource availability can change at any time during the application execution lifetime. Grid Quality of Service (QoS) approaches seek to guarantee a minimum level of resource availability by reserving resources for certain applications [8]. The approach described in this thesis differs from traditional performance prediction methods in that it does not rely on a dedicated set of resources being available for the entire application run. It is often not possible to reserve resources or make performance guarantees, because of the ....

....The work applies particularly in the case of remote method invocations to objects over a wide area network. Kon et al. in [15] proposes a reflective middleware architecture DynamicTAO in order to transparently reconfigure itself to adapt to environmental changes. Finally, the GARA architecture [10, 9] integrates both CPU and network QoS provisioning by providing resource reservations to a required lower bound, and graceful adaptation beyond such guaranteed level. Finally, recent work has focused on QoS aware monitoring and probing mechanisms at the application level [11, 4, 3, 14, 7, 23, 1] ....

....reservation capabilities include creating, modifying, claiming, and removing reservations. In particular, the RM encapsulates a scheduler that understands advance reservation (e.g. a time slot based system as opposed to a batch scheduler) The current implementation provides a slot scheduler [10, 9] that is used by default, but we are investigating how to use existing schedulers such as Maui [15, 4] or DSRT [5] instead so sites may use whatever scheduler is appropriate. An RM may authenticate and perform access control checks on a requestor. It coordinates the scheduling of the restriction ....

Other work Related work in bandwidth partitioning and reservation is being pursued by the Globus project and the Internet2 Quality of Service Backbone (I2 QBone) testbed. The Globus Architecture for Reservation and Allocation (GARA) [9] defines a QoS architecture that supports flow specific QoS specification as well as advance reservation. GARA developers Lawrence Berkeley National Laboratory qosdev george.lbl.gov 9 have conducted tests of their reservation framework in the wide area using a testbed that includes Lawrence ....

....a guaranteed rate environment, if the rate at which the TCP sender injects packets into the network temporarily exceeds the guaranteed rate such that packet drops can occur. Shaping of TCP streams at the target guaranteed rate is a preferable means to pace the TCP data rate to the guaranteed rate [15, 23, 24, 25]. Doing so allows to avoid packet drops and achieves a smooth TCP transmission at the guaranteed rate. To address the discussed shortcomings, we developed a multi class Grid FTP as an example for a high data rate TCP based application. It is configured to apply a Guaranteed Rate Service and a Low ....

....and the special topology of a certain DS domain is available. In [15] a central resource management for DS domains called a Bandwidth Broker (BB) is presented. A BB is a middleware service which controls and facilitates the dynamic access to network services of a particular administrative domain [10]. The task of a BB in a DS domain is to perform a careful admission control, and to set up the appropriate configuration of the domain s edge routers, whereas the configuration of core routers is intended to remain static to allow for scalability. While doing so, the BB knows about all requests ....

....simultaneously. For example, large distributed simulations [6] can require access to many large computational resources at one time. On line experiments [38] require that computational resources be available when the experiment is being conducted, and processing pipelines such as data transfer [21], data analysis [25, 3] and visualization pipelines [8] require simulations access to a balanced resource set. Given that each of the resources in question may be owned and operated by a different provider, establishing a single SLA across all of the desired resources is not possible. One ....

.... we refer to the protocols used to negotiate these SLAs as the Service Negotiation and Acquisition Protocol (SNAP) The service management approach proposed here extends techniques first developed within the Globus Toolkit s GRAM service [10] and then extended in the experimental GARA system [20, 21, 33]. An implementation of this architecture and protocol can leverage a variety of existing infrastructure, including the Globus Toolkit s Grid Security Infrastructure [18] and Monitoring and Discovery Service [9] We expect SNAP protocol to be easily implemented within the Open Grid Services ....

....differently. However, it was straightforward to modify the network resource manager to work with the Extreme routers. Demonstration of network QoS With this testbed, we have demonstrated our ability to provide network QoS. Although many of the detailed results have been documented elsewhere ([25, 51, 50, 24]) we provide an overview here. In the demonstrations that follow, we used TCP and UDP traffic generators capable of generating traffic at a constant rate. These traffic generators were used both for the traffic that had reservations and the traffic that attempted to interfere with the reserved ....

....6. Overhead of lots This graph shows the overhead imposed by implementing lots using the kernel quota system. Notice that for small files, the cost is negligible but increases quickly with file size. Within the Grid community, there are a number of projects that are related to NeST. GARA [28] is an architecture that provides advance reservations across a variety of resources, including computers, networks, and storage devices. Like NeST, GARA provides reservations (similar to NeST s lots) but allows users to make them in advance. However, GARA does not provide the best effort lots or ....

....have developed what we call an end to end reservation API within our General purpose Architecture for Reservation and Allocation (GARA) system. GARA provides advance reservations and end to end management for quality of service on different types of resources, including networks, CPUs, and disks [10, 11]. It defines APIs that allows users and applications to manipulate reservations of different resources in uniform ways. For networking resources, GARA implements a bandwidth broker as described above. A library provided by GARA implements an end to end network API that facilitates end to end ....
