Riassunto analitico
In this paper we focus on dynamically allocating resources to service requests (SRs), which arrive and leave over time and are generated by applications with heterogeneous requirements, in a joint multi-layer and application-aware fashion.
To do so, we use a novel resource allocation algorithm, the Application-Aware (AA) algorithm, able to jointly allocate resources on IP/MPLS and optical layers, while meeting multiple optional application requirements like bandwidth, latency, availability, encryption.
The algorithm exploits the concept of Auxiliary Graphs (AGs), to provide application-awareness for each SR. Moreover, the algorithm has a modular design, i.e., it can be easily extended to consider further application requirements (ARs).
We ran various simulations to evaluate the AA Algorithm performance by comparing them with Baseline (application-unaware) algorithm performance.
We evaluate this two algorithm in terms of both Blocking Probability (BP) and of AR Violation Probability (VP) for the SRs and Convergence Times.
