- Abstract:
- Current service carrying network mapping algorithms ignored the business category of the service request, which resulted in the disconnection between the business carrying phase. To address this problem, a novel end-to-end service provisioning model was proposed, in which service carrying networks were constructed considering aggregating service requests belonging to the same business category and customized end-to-end services were provied via establishing the corresponding service path over the service carrying network. To evaluate the feasibility and effectiveness of the proposed model, a service carrying network mapping algorithm with hop constraint ws and desighed Layered Graph algorithm was used to select service path. Simulation experiments on a large mix of service requests showed the impact the hop constraint had on network performance in trems of cost, revenue, acceptance ratio, length of service path, etc. under different working load, validated the effectiveness of the proposed model and algorithms, and eventually determined the optimal value of hops. When the value of hops equaled 3, compared with the situation in which the value of hops equals 4 or 5, the achieved performance was approximately same, and about 50 percent and 75 percent cost of constructing service carrying vetwork can be saved respectively.
