“…This is a much more realistic scenario, and has multiple applications, e.g. In [9] a hierarchy of brokers (called Resource Control Points) is presented, too. The authors mention, that dividing the network into parts, each managed by a single broker is not trivial and needs the knowledge of the topology as well as information about the expected SLAs.…”

Abstract. The need of a powerful tool for the management of large backbone networks is growing. Furthermore, new applications and user behavior require the ability to quickly adapt the network configuration to a dynamically changing environment. We present an architecture and an implementation of a bandwidth broker for DiffServ network management. The performance evaluation shows, that our implementation is able to serve as the central management station for a network containing several hundred nodes while still providing a short flow setup time. Further improvements of the current implementation are discussed, too.

“…Serious concerns about operational cost and complexity have to be considered, too. Some of those problems are addressed by existing architectures of bandwidth brokers [9,10]. All of them try to reduce the complexity of the configuration procedure.…”

Bandwidth broker (BB), resource manager of differentiated services domain cannot provide per domain behavior (PDB) attribute information to customers and neighboring domains at the time of service level agreement (SLA) negotiation. Extending BB`s functionality to calculate PDB attributes can help it to negotiate SLAs dynamically and efficiently. Using current measurements or historic data about PDB attributes, bandwidth broker can perform off-line analysis to evaluate the range of quality of service (QoS) parameters that its domain can offer. Using these values BB can perform optimal capacity planning of the links and provide better QoS guarantees.

“…The Edge Router also marks packets and aggregates their corresponding flows into groups under the same DiffServ Codepoint. The main innovation of the Aquila architecture is a new layer on top of the DiffServ core ISP network, called the Resource Control Layer (RCL) [7]. The RCL is responsible for the management of network resources.…”

Abstract.Internet is widely known for lacking any kind of mechanism for the provisioning of Quality of Service (QoS) guarantees. The Internet community currently concentrates its efforts on mechanisms that support QoS in various layers of the OSI model. Apart from that, the Internet community is trying also to define the protocols, through which applications and users will signal their QoS requirements to the lower network layer mechanisms. The latter task, however, is not trivial, especially for legacy applications that cannot be modified and recompiled. This paper presents a framework for a middleware component that supports QoS for legacy applications. It mainly focuses on the support of a proxy-based framework for the identification of flows, the measurement of basic QoS parameters and the definition of an API that can be used by middleware components or even applications. The position of this proxy architecture in a reference network topology and the communication with other middleware entities is also discussed.
