Abstract:

The cellular networks, which are currently serving 5 billion cellular phones and mobile devices globally, have employed centralized control with different network functions arranged in a hierarchy. Standardization of Internet mobility management in the Internet Engineering Task Force (IETF) has been primarily in centralized mobility management including Mobile IPv6 (MIPv6) and its extensions, and the deployments primarily been in a centralized manner for the hierarchical cellular networks. Yet there are already numerous variants and extensions of MIPv6 including Proxy Mobile IPv6 (PMIPv6), Hierarchical MIPv6 (HMIPv6), and Network Mobility (NEMO), which have been developed over the years owing to the different needs that are found afterwards.

Deployment of Internet mobility mechanisms can then become complicated, especially when interoperability with different deployments are an issue. The Internet has employed distributed control functions resulting in a more flattened effect, i.e., less hierarchical. This result augments into predicting that the needed mobility management functions will become distributed rather than centralized. Despite the large amount of standards work in Internet mobility in IETF primarily with centralized mobility, the deployment in the Internet is still slow. Such a fundamental change to distributed mobility is needed in the mobile Internet.

Mobility management with centralized mobility anchoring in existing hierarchical mobile networks is quite prone to suboptimal routing and issues related to scalability. Centralized functions present a single point of failure, and inevitably introduce longer delays and higher signaling loads for network operations related to mobility management. To make matters worse, there are numerous variants of Mobile IP in addition to other protocols standardized outside the IETF, making it much more difficult to create economical and interoperable solutions. The existing mobility management standards in IETF, the issues of mobility management for the future mobile Internet, the trend of the mobile Internet and the proposed distributed mobility at IETF are explained. 

 

Biography:


H. Anthony Chan received his PhD in physics at University of Maryland, College Park in 1982 and then continued post-doctorate research there in basic science. After joining the former AT&T Bell Labs in 1986, his work moved to industry-oriented research in areas of interconnection, electronic packaging, reliability, and assembly in manufacturing, and then moved again to network management, network architecture and standards for both wireless and wire line networks. He was the AT&T delegate in several standards work groups under 3GPP. He then moved to academia as professor at University of Cape Town to lead the curriculum and research in telecommunications, making transformations in such program to contribute to the needs for an African country to catch up with the Digital Divide.

In 2007, he returned to industry as a Researcher when he joined Huawei Technologies. His current research is in emerging broadband wireless network technologies. He contributed to mobility standards in both IETF and IEEE and is the editor of an IETF DMM Working Group draft on the requirements on distributed mobility management.

Dr. Chan is a Fellow of IEEE, chair of IEEE Standard 802.21c Task Group on Single Radio Handover Optimization, Vice-chair of IEEE standard 802.21 Working Group on Media Independent Handover. He is currently a Distinguished Lecturer/Speaker of IEEE Communication Society and a Distinguisher Lecturer/Speaker of IEEE Reliability Society.
