Walter Chen, Sprint

Walter Chen has been with Sprint for 16 years and is currently a Network Planner IV in IP Engineering department. He had been responsible for SprintLink IP core network strategies, architecture, capacity forecast and planning since 2006, and has the similar responsibility for Sprint’s Next Generation Wireless WAN core network. He is also responsible for the Sprint wireline IP network capital unit cost models, and also participated in formulating the unit cost model for the optical transport networks. At Sprint, he introduced more rigorous numerical methodology into core network capacity forecasting and planning, used network simulation tools such as Cariden/Cisco MATE and WANDL/Juniper IPMPLSView in both network topology optimization and green-field network design and modeling work. Walter holds a PhD in Astrophysics from The Johns Hopkins University, and worked at NASA Goddard Space Flight Center before joining the telecom industry in 1999.
Abstract: For a service provider, or any enterprise with substantial network infrastructure, achieving a high network efficiency is often a noble goal or even an important KPI. While the term “network efficiency” has been used widely, for different organizations it could mean totally different objectives. In this talk, we try to define and quantify three different aspects of the so-called network efficiency and then discuss the implications and interworking between these objectives, from both organizational, financial and technical perspectives. We propose a novel approach in packet-optical networking to achieve the ultimate capacity efficiency, and also discuss the potential significant impact of recent control plane innovation such as SDN on this subject.
