Constrained dynamic virtual network embedding
Résumé
This paper focuses on a dynamic embedding of
client-constrained heterogeneous Virtual Network (VN) requests
with multiple nodes and links anti-affinity requirements. For
this Virtual Network Embedding (VNE) problem, we formulate
an Integer-Linear Programming (ILP) model that achieves joint
mapping of virtual nodes and links of each VN onto the Substrate
Network (SN) and that meets the clients expressed isolation
constraints. We include VNs arrivals and departures in an
ILP-based framework that updates SN topology and resources
dynamically. Numerical experiments illustrate the efficiency of
the proposed methods and their ability to find optimal solutions.
Performance reports provide insight to cloud service providers
on additional investments in nodes and links they should make
to service clients with anti-affinity requirements.
