“…Resource negotiations have also been employed in several use cases, e.g. among content delivery network operators and InP [18], stakeholders of heterogeneous wireless networks [19], support survivability in a multi-domain virtual network embedding [20], and threshold-based grid resource management [17].…”

Repeated Leader Follower Game for Managing Cloud Networks With Limited Resources

Virtual resource arbitration, adjustment, and migration are techniques used by infrastructure providers (InPs) to manage limited resources and maximize revenue by serving as many virtual network operators (VNOs) as possible. However, these techniques tend to violate service level agreements (SLAs) and require InPs to compensate VNOs, resulting in reduced benefits. As reported in the literature, no more than 20% of leased cloud resources are actually used. Therefore, InPs and VNOs can both benefit if some of these resources can be returned to the InPs. In this paper, we model a process for negotiating resource returns using a repeated leader follower game. InP (the leader) offers VNOs (the followers) compensation for returning resources with the objective of creating a pool of resources that can be allocated to other VNOs. In this manner, we can maximize the utility of InP and VNO. In particular, an InP increases utility by increasing its revenue, and VNOs increase their utility because their workload can be completed at a lower price owing to received compensations. We numerically evaluate these utilities using the three strategies that we propose and make comparisons against two conventional strategies. Our three strategies focus on revenue maximization of the InP, preferences of VNOs, and the previous negotiation histories. We observe that, after serving new requests using our first and third proposed strategy, the utility of InP increases by 5% and 13%, respectively, compared with using conventional strategies.

“…One of the challenges in building the vCDN service is to adapt the service topology (CGs-vMGs-vSTRs-CDN points) to the ISP topology to lower the deployment cost. To this end, we proposed [15] an algorithm that uses heuristics to generate the service topology, then computes the embedding with a Linear Programming solver including both SLAs and ISP topology constraints. We use a cost function that minimizes ISP cost to produce the embedding of Services Function Chains.…”

Today, Over-the-Top video streaming is gaining a lot of popularity. In this respect, the Virtual Content Delivery Network (CDN) is perceived as a key enabler to circumvent the technical challenges faced by Content Providers (CP) to deliver highquality content over the Internet. In this paper, we investigate how the two main actors of the video delivery chain, i.e., the CDN operator and the Internet Service Provider (ISP), can benefit from network and server virtualization to negotiate Dynamic Service Level Agreements that reduce CDN CAPEX and OPEX, while generating more revenue for the ISP. First, we present a dataset used to simulate dynamic distributed traffic consumption. Second, we discuss the steps required to deploy and operate a virtual CDN deployed on an ISP's network. Furthermore, we present evaluation results of the proposed solution, based on simple models. Lastly, we elaborate on operational parameters that are used to further optimize the solution.

“…Regarding VNF based optimization, collaboration between content delivery stakeholders and optimization based on SLA is investigated in [15]- [18]. In [15], a model for the collaboration between content delivery stakeholders is proposed. A high-level SLA is used for the negotiation of both computing resources and connectivity.…”

“…In [11], the optimal placement of composing VNFs with adequate amount of virtual resources for each VNF is formulated by bargaining game to allocate an appropriate set of VNFs for each CDN slice to meet its performance requirements and minimize the cost in terms of allocated virtual resources. In [15], a linear programming formulation is presented for the VNF embedding to increase problem tractability with a small cost overhead. In [17], a game-theoretic analysis is presented for different ISP-CDN collaboration models and optimality conditions.…”

Content service has become the most popular service that occupies plenty of caching and networking resources. In order to deliver content to end users with high QoE and low infrastructure cost, network function virtualization is deemed as a promising solution for operators to provide content service with geographically dispersed nodes in large scale, which paves the way towards the virtualized content network. In this paper, from the point of view of information-centric networking and service provision, an information-centric virtual content network (IVCN) slicing framework is proposed. A method on the VNF partition from the point of view of information-centric networking and service provision is put forward. The service function chaining and optimization of IVCN are investigated both on the data plane and on the control plane. The IVCN slicing is modeled as a use case in heterogeneous fog-enabled RAN. A method of performance optimization on the IVCN slicing is proposed based on SFC, which aims to optimize the mapping of virtual network functions and virtual content placement. A heuristic approach called IVCN-RANO is proposed to solve the NP-hard problem based on ant colony optimization algorithm. The performance of the IVCN-RANO is evaluated comparing with CEE-LRU, Prob-LRU, and popularity-based schemes. The simulation results reveal that IVCN-RANO outperforms on performances including hit rate, average weighted hops, and average content redundancy.
