Rational Impatience Admission Control in 5G-sliced Networks: Shall I Bide my Slice Opportunity?

Recently, the specifications of the fifth generation (5G) of mobile networks have been released witnessing the industrial interest around the novel network slicing concept. This context is further enriched by the evolution of an emerging type of public cloud environment: the Slice-as-a-Service (SlaaS). Infrastructure providers or network operators deploy different admission strategy while processing network slice requests issued by infrastructure tenants based on service level agreements (SLAs) and current (and predicted) resource availability. However, when the service demand will reasonably get dense, congestions of slice requests may occur leading to long waiting periods. This may turn into impatient tenant behaviors that mitigate potential loss. This paper studies the rational strategies of impatient tenants waiting in queue-based slice admission control system, proving mathematically and empirically the benefits of allowing infrastructure provider to share its information with the upcoming tenants.
