The scientific contributions the candidate is likely to make to the workshop, including a
brief description of areas of expertise
The Quality of Service (QoS) in IP networks has been studied extensively over the years, with
MPLS/GMPLS being the latest scheme for QoS in IP networks. MPLS/GMPLS introduces
connection-oriented features into the otherwise connectionless IP network. The advent of the
Future Heterogeneous Networks and its emphasis on QoS capable transport networks has brought
to prominence the need for connections with QoS guarantees. The services of future
heterogeneous networks will require a seamless connectivity between heterogeneous networks
operated by different Internet service providers (ISPs), each with a different data rate offered to
the users. Such a connection should have the ability to efficiently support heterogeneous voice,
video and data services with several orders spread in transaction sizes and rates and with
heterogeneous priority. Consequently, the issue of how to establish a connection with QoS
requirements across multiple domains operated by different operators has become an important
but challenging research topic. The functional components of establishing end-to-end paths with
QoS requirements in a network can be separated into the mechanisms for discovering reachability
and QoS information in order to compute paths, and for signaling the establishment and tearing
down of paths. For the past few years, we have studied the computation of end-to-end paths with
QoS guarantees over heterogeneous networks in a cross-domain environment with several papers.
We assume that once an end-to-end path has been calculated, it can be signaled using a protocol
such as RSVP-TE or LDP. Furthermore, due to the complexity of a large-scale network, it is
necessary for us to validate these approaches by conducting such research experiments on a largescale testbed. Thus, we have recently started to conduct research experiments on GENI supported
by the NSF GENI research grant and further brought them into my teaching in networking and
security classes. Hence, it would be my pleasure sharing my research and industrial experience in
designing the architecture of future heterogeneous networks with colleagues and workshop
attendees. My current research interest includes cross-network management, control, and
security, and dynamic resource allocation over heterogeneous networks.
The reasons why participation in the workshop will benefit the candidate
As is noticed, my current research exactly includes the topics and areas for exploration stated in
the announcement of the workshop. I believe that the workshop would provide me an excellent
opportunity to exchange my new ideas with colleagues, learn from them, and get the updated
information of the architecture design of future heterogeneous networks. Such a
communication opportunity might have a great impact on my current and future research of
heterogeneous networks. Thus, I sincerely hope to have the opportunity to attend the
workshop for a better understanding of the current and future research direction of
heterogeneous network designs by learning from colleagues and sharing my experience with
attendees.
A statement indicating whether NSF travel support is requested or is not requested
Due to the budget limit, I would like to apply for the travel grant of the FutureHetNets
2011 workshop. Please do not hesitate to contact me if you need any further information.
I would appreciate it if you could grant me the opportunity to attend the wonderful workshop.
