Title: PhD Thesis Proposal: Multi-Layer Virtual Transport Network Design  
and Management (Yuefeng Wang)
PhD Thesis Proposal
Multi-Layer Virtual Transport Network Design and Management
Yuefeng Wang, Boston University

Nowadays there is an increasing need for a general management paradigm,  
which can simplify network management and further enable network  
innovations. Software Defined Networking (SDN) is an efficient way to make  
the network programmable and reduce management complexity, however it is  
plagued with limitations inherited from the legacy Internet (TCP/IP)  
architecture.  On the other hand, service overlay networks and virtual  
networks are widely used to overcome deficiencies of the Internet.   
However, most overlay/virtual networks are single-layered and lack dynamic  
scope management. Furthermore, how to solve the joint problem of designing  
and mapping the overlay/virtual network requests for better application and  
network performance remains an understudied area.

In this thesis, in response to limitations of current SDN management  
solutions and of the traditional single-layer overlay/virtual network  
design, we propose a recursive approach to enterprise network management,  
where network management is done through managing various Virtual Transport  
Networks (VTNs) over different scopes (i.e., regions of operation).  
Different from the traditional overlay/virtual network model which mainly  
focuses on routing/tunneling, our VTN approach provides communication  
service with explicit Quality-of-Service (QoS) support for applications via  
transport flows, i.e., it involves all mechanisms (e.g., routing,  
addressing, error and flow control, resource allocation) needed to meet  
application requirements.  Our approach inherently provides a multi-layer  
solution for overlay/virtual network design.

The contributions of this thesis are threefold:  (1) we propose a novel  
VTN-based management approach to enterprise network management; (2) we  
develop a framework for multi-layer VTN design and instantiate it to meet  
specific application and network goals; and (3) we design and prototype a  
VTN-based management architecture to validate our VTN design algorithms.  
Our simulation and preliminary experimental results demonstrate the  
flexibility of our VTN-based management approach and its performance
