*Subject: Network/Cloud joint design and global optimization*

*Proposed by *

*Prof. Daniel Kofman; contact: **daniel.kofman at telecom-paristech.fr

*General Context*

Cloud services were originally deployed over the top, in particular over 
the Internet. More recently companies are deploying their own private 
cloud solutions and we see a need for portability and interoperability 
of public and private clouds.

We expect that brokers will become key players in such future solutions. 
Historically, telecom service providers were focused on supplying 
connectivity based on the VPN concept. These services have evolved to 
facilitate outsourcing of advanced functionality like routing and even 
security (L3 IP VPNs, security as a service, etc.).

VPN service providers started to offer dynamic access trough VPNs to 
their own cloud services and also to 3^rd party cloud services; e.g., 
the "VPN gallery service" of Orange Business Services. In the future, 
such services will enable dynamic mapping of cloud services over 
existing VPNs, hence allowing the VPN service provider to become a 
broker of cloud-based infrastructure and services. Moreover, cloud 
resources that are controlled by service providers will move out of 
large datacenters to be located in various other points, including 
telecom service providers, networking PoPs, and even customers locations 
(e.g. in CPEs).

This requires a joint network/cloud architecture as well as global 
optimization of resources. Indeed, the dynamism of cloud based services 
cannot be really achieved without an associated dynamic control of 
network resources.

Moreover, we foresee in the midterm a new generation of brokers that 
will dynamically select from among various providers and orchestrate 
both network and cloud services to answer dynamically specific client's 
requirements.

*Topics of research *

The proposed research activity will focus on the following main topics:

 1. Defining the overall joint network/cloud architecture so as to
    enable the dynamic creation of enterprise services. Introducing the
    concept of "broker" in the global architecture.
 2. Design of the required resource optimization mechanisms, covering
    jointly network and cloud resources.
 3. Design of other optimization mechanisms, such as content location
    over distributed clouds (as opposed to datacenter-based clouds).
 4. Proposal and performance analysis of pricing models to clients and
    business models among the players.

*Timeframe and Place(s)*

The extent of the position is for one year and may be extended for 
additional 6 months. The research can be conducted at either

  * Telecom ParisTech (Paris, France) and more specifically at the LINCS
    (www.lincs.fr <http://www.lincs.fr>) a joint laboratory recently
    created by INRIA, Institut Telecom, UPMC and Alcatel-Lucent Bell labs,
  * The Department of Electrical Engineering, Technion (Haifa, Israel),
  * RAD Data Communications (Tel-Aviv, Israel).

The candidate can share her/his research time among these sites as per 
her/his preferences.
