SDN based LTE Network Architectures
A talk about SDN based LTE Network Architectures.
Speaker: Krishna M. Sivalingam, Professor, Department of CSE, IIT Madras, India
Abstract:
Cellular Network providers oftyen selectively offload mobile data traffic to WiFi (IEEE 802.11) networks in order to balance the load and improve network performance. Several architectures based on Proxy Mobile IPv6 (PMIPv6) have been proposed to support seamless data offloading. The demerits of PMIPv6 include lack of flow mobility and single point of failure. In this talk, we propose the Seamless Internetwork Flow Mobility (SIFM) architecture that overcomes these drawbacks and provides seamless data offload supporting flow mobility. Both the PMIPv6 and the SIFM architectures have been implemented and evaluated incorporating salient LTE and WiFi network features in the ns-3 simulator.
The talk will also present an SDN-based Evolved Packet Core (EPC) architecture for LTE networks. The proposed EPC architecture centralizes the control plane functionality of EPC thereby eliminating the use of mobility management protocols and reducing mobility related signaling costs. The architecture utilizes the global network view feature of SDN for mobility management. The proposed architecture has been implemented in the ns-3 simulator framework and studied.
The ongoing efforts to implement these architectures in a testbed will also be briefly presented.
This talk is based on recent work (to be) reported in IEEE WoWMoM 2015 and IEEE NetSoft 2015.
