“…Selected research works that belong to the first group are [3] and [4]: in the former the authors use Integer Linear Programming (ILP) to solve the VNE problem for minimizing the cost of embedding in terms of edge costs while maximizing the acceptance ratio; in the latter the authors propose a MIP (Mixed ILP) formulation for reconfiguring existing mapping by enabling migrations. The second group, i.e., approaches that solve the VNE problem with heuristic algorithms, also shows a colorful palette of ideas.…”

Abstract-Next generation networks and applications have recently drawn the attention of many researchers in both academia and industry. The plethora of service orchestration, embedding and scheduling solutions being developed indicates that efficient resource utilization in the cloud and edge/fog architecture is of crucial importance in order to exploit the great economic potential of this infrastructure. In this paper we propose a novel service orchestration approach that aims for speed and quality in terms of service provisioning: our embedding algorithm instantly deploys end-to-end delay-constrained service graphs while regularly offloads the most burdened parts of the infrastructure applying a cost-aware VNF migration strategy. In this sense we propose a hybrid orchestration approach, which unites the advantages of online heuristic and offline optimizing service orchestration methods, with the goal of obtaining a system design that provides fast service placement decisions and efficient long-term operation. By an exhaustive evaluation of our orchestration system on core, cloud and edge network topologies, we show its benefits in efficiency and the collateral cost of migrations.

In [7] a request is split among infrastructure providers with respect to an abstract view of the underlying (AS-level) network. However, no discussion on possible trade-offs is present.…”

Abstract-Through network function virtualization (NFV), telecom providers aim to flexibly re-use generic-purpose hardware to provide services on-demand and in an agile way. Service function chaining is becoming the preferred model to describe the characteristics of the packet-processing network functions which, together, form these services. NFV allows for network function embedding freedom, creating new dynamics between providers and the users requesting services. Users want this freedom to optimise the performance of their requested services, while providers aim to optimise their resource cost with it. This trade-off is heavily influenced by how the available infrastructure is exposed to the users. In this paper, we present an infrastructure abstraction model for network, compute and storage resources that exposes the infrastructure in an abstracted manner. We use this abstraction to propose a solution for the placement freedom trade-off problem by studying its relation with metrics that capture both the user's and the provider's aspects. We conclude with a heuristic that determines the right abstraction for particular scenarios.
