SLA Establishment with Guaranteed QoS in the Interdomain Network: A Stock Model

“…In the traffic matrix, we focus on the necessary capacity of each source (each node) to transit its own traffic to node 6. We fix these components to 3 Fig13 and Fig14) show the benefit of each node at each stage. We clearly see in (Fig13) that node 6 increases its benefit from the first stage to the stage 25, this increase of benefit can be interpreted by the fact that all nodes increase their minimum capacities.…”

“…According to [4] the negotiation between both parties (customer and provider) reflects SLS (Service Level Specification) which contains a set of technical parameters that define the level of service provided by a domain. Provisioning is one of the phases that SLA contains in its life cycle [3] and [4], this phase consists in reserving resources and activating the service. In this paper we show how to implement the management of resources and inter-domain QoS guaranteed services, while taking into account the economic constraints of the various operators in the inter-domain network.…”

“…For purchasing a route to a given destination, we consider that each domain in the network negotiates with its neighbor (transit provider) the capacity and its availability on this route. In this case, the customer asks to its provider for a minimum capacity 1 and a maximum capacity 2 , it also asks for a period of availability 3 of the capacity asked on this route. This customer must also choose a start time 4 of a period asked.…”

“…In [1], both a theoretical game and a distributed algorithmic approach are presented for the transit price negotiation problem in the inter-domain routing framework and the authors 1 minimum capacity asked by an operator to its neighbor on a route to a given destination 2 maximum capacity asked by an operator to its neighbor on a route to a given destination. 3 A period asked by an operator to its neighbor on a route to a given destination. 4 beginning of the period of availability of a route asked by a customer to its neighbor.…”

“…minimum capacity asked by an operator to its neighbor on a route to a given destination 2 maximum capacity asked by an operator to its neighbor on a route to a given destination 3. A period asked by an operator to its neighbor on a route to a given destination 4.…”
