....and finally, section VI presents the conclusions and suggestions for future works. II. RELATED WORKS Recently, several schemes concerning resource provisioning for IP networks have been proposed. The Tequila Project (Traffic Engineering for Quality of Service in Internet, at Large Scale) [8], 9] 10] aims at investigating provisioning techniques, admission control and dynamic resource management for DiffServ networks. The proposed architecture is composed of two functional groups. The first includes the SLS (Service Level Specification) Manager that is responsible for users ....

....configured in the network via the network configuration API (see Section 4, implementation for a more detailed view of the then called QoS Management API) 2. 2 Service Level Specification As a starting point we take the Service Level Specifications submitted to the IETF by the TEQUILA project [TEQ] including the parameters proposed in it. In the following we list the parameters with a very short description. Scope specifies on what paths the QoS policy is to be enforced. It is expressed by a couple of ingress and egress interfaces. Note that the scope parameters enables one to any, and ....

....be expressed as a list of parameters and values, which is what the Mapping Schema is expecting, and what the network can deal with. The SLS might be expressed in terms of Service X , which may be a pre defined service [AQUI] These pre defined services are mapped to the SLS parameters proposed in [TEQ] by the pre def mapping block. Furthermore, the SLS could also be expressed, for simplicity, in terms of low medium high delay loss . These values are mapped to numeric values, so that our system can deal with them. This SLS to DiffServ configuration mappings Error OK Similar Service ....

....between peered domains comes into place, used by BBs as input for their admission control procedures. A service level agreement (SLA) regulates the acceptance and the constraints of a given traffic profile. Service Level Specifications (SLS) are used to describe the appropriate QoS parameters [22] that an SLA demands. End to end guarantees can then be built by a chain of SLSs. 3 Co Reservations and Inter BB Signalling It is unlikely that a single bandwidth broker will control more than one domain, because each administrative domain wishes to have control over the resources it owns.

....dimensioning and dynamic control of traffic management techniques based upon the Differentiated Services (DiffServ) architecture [1] in a flexible policy driven manner. The TEQUILA system is composed of a set of elementary blocks that comprise traffic engineering management capabilities [2] [3]. It relies upon the use of classical IP routing protocols for the establishment of#IP routes, as well as the use of the Multi Protocol Label Switching (MPLS) technique [4] for the establishment of# Label Switched Paths (LSPs) that are expected to comply with the QoS requirements specified ....
