Título: Network Function Virtualization (NFV) Meets the Cloud: Challenges and Solutions

Horário: 31/05/2016 – 16:00-17:00


Network Function Virtualization (NFV) is an emerging topic both in the academia and in the industry. The basic premise of NFV is to virtualize network middleboxes (e.g., NAT, firewall) that are traditionally hardware appliances. Virtualization provides all the typical benefits of cloud computing including scalability to workload changes (autoscaling), flexibility, and lowered costs. However, Virtual Network Functions (VNFs) are often more demanding than typical virtual machines (VM) in a cloud infrastructure with regard to attributes such as performance, reliability, predictability, and security. In this talk, I will look at the problems from both the VNF provider’s (a cloud user) and the cloud provider’s perspectives. I will describe some of our recent work on extending the OpenStack, an open source cloud computing software, and outline some of our thinking of management of VNFs in a world-wide network.
