3 Cisco Enterprise Silicon: Delivering Innovation for Advanced Routing and Switching Session Overview and Objectives Come to this session to learn about the latest advances in Cisco Enterprise silicon development ASIC (Application Specific Integrated Circuit) hardware which provides a key foundational element of the Cisco ONE Enterprise Architecture, and which support key industry trends such as SDN. Attendees at this session will gain a greater insight into how ASICs are created, showcasing the advanced capabilities and functionality delivered by two of Cisco s latest switching and routing silicon innovations UADP (Unified Access Data Plane) and QFP (QuantumFlow Processor). By developing custom silicon, and leveraging this advanced hardware within our Enterprise portfolio, Cisco has always provided differentiating capabilities and compelling customer value across many platforms. In this session, we will explore the capabilities and advantages provided by custom Cisco silicon, provide greater insight into the functionality delivered by existing Cisco Enterprise ASICs, and explore the new capabilities and solutions enabled by Cisco's latest generation of Enterprisefocused programmable switching and routing chipsets UADP and QFP.
4 Cisco Enterprise Silicon: Delivering Innovation for Advanced Routing and Switching Your Instructors Today Carl Solder and Dave Zacks Carl is a Director of Engineering, and has been with Cisco for 18 years. Carl has extensive experience with many types of Enterprise network systems and deployments, and has a intense focus on competitive analysis of solutions from Cisco and others. Dave is a Distinguished Engineer, and has been with Cisco for 15 years. Dave works primarily with large, high-performance Enterprise network architectures, designs, and systems. Dave has over 20 years of experience with designing, implementing, and supporting solutions with many diverse network technologies. We both have a strong interest in ASIC hardware and solutions a passion we hope to share with you via this presentation! Carl Solder Director Dave Zacks Dist. Engineer
