Management of resources under priorities in EON using a modified RDM based on the squatting-kicking approach

Abstract

The paper proposes a resources allocation method for EON based on a modified RDM using squatting and kicking strategies in order to prioritise the usage of channels and enhancing the total utilisation. It can also be used as an admission control. The mechanism is described and compared to existing proposals, regarding the flexibility in\ud the allocation per class. The strategy regards the EON constraints and assumes the optical spectrum to be partitioned and reserved to several different classes. These partitions are allocated according to the priority of the demands and the strategy proposed. The performance metrics are explained and analysed via demands and resources allocation examples.Peer ReviewedPostprint (published version

Squatting and kicking model evaluation for prioritized sliced resource management

“…Preemption and squatting are consistent approaches that can be adapted to guarantee QoS. Thus, BAMs such as MAM, RDM, and AllocTC, with a reservation are used as preemption strategies while BAM with squatting and kicking strategies (soft and hard) are discussed in [35].…”

“…In our previous works, [35,41,42], we proposed the concept of SKM in order to give 100% overall network utilization while guaranteeing high admission for higher priority classes for any resources (e.g., EON) as the following: In [35] the authors propose a resources allocation method for EON based on a modified RDM using squatting and kicking strategies in order to prioritize the usage of channels and enhancing the total utilization which can also be used as an admission control. The mechanism is described and compared to existing proposals for a few representative numerical examples, regarding the flexibility in the allocation per class.…”

“…These partitions are allocated according to the priority of the demands and the strategy proposed. This work extends the concepts in [35] by adding online and offline distinction and giving the algorithms in a more formal framework. Moreover, in this work, the performance of the proposed algorithms is analyzed by not only representative examples but also simulations that vary the system parameters.…”

“…It must be noted that squatting can be applied over resources allocated to either higher priority classes (default behaviour) or lower priority ones. This concept is further elaborated in the following sections [35,41].…”
