Ethernet Evolving: Ethernet at New Speeds, Deterministic Networking, and Power over Everything! Dave Zacks Distinguished System #BRKCRS3900 Peter Jones BRKCRS-3900 Principal #HighBitRate #DynamicDuo Ethernet Evolving: Ethernet at New Speeds, Deterministic Networking, and Power over Everything! BRKCRS-3900 Session Overview We have a great session for you today so sit back, buckle in, and let s get started! Come to this session to get geared up on the latest developments in Ethernet for Campus and Branch networks. The Ethernet we all know and love is evolving at a rapid pace. With the release of MultiGigabit Ethernet on Cisco's latest Catalyst access switching platforms, you can connect new devices that support MultiGigabit connections at 2.5Gb/s and 5Gb/s over Cat5e/6 copper. No longer are 1Gbps and 10Gbps the only connectivity options intermediate speeds are now possible. Cisco s Multigigabit Technology is a key enabler for upcoming ac Wave 2 wireless deployments, where the Ethernet bandwidth required per AP exceeds 1Gb/s. Multigigabit switches also support other high-bandwidth devices in the Ethernet access layer without requiring expensive and time-consuming re-cabling for 10GBASE-T. We will talk about how Cisco MultiGigabit switches work, and how they will change your network. As well, we will discuss work being done in (and out of) the standards bodies to broaden the footprint for Ethernet, and enable the Internet of Everything. This includes additional Ethernet speeds, capabilities for deterministic networking functionality over an Ethernet infrastructure (precision timing, pre-emption, time scheduling, etc), and of course we need to provide more Power over Ethernet to more devices, in more places, than ever. Come to the session to get the latest scoop! Ethernet Evolving: Ethernet at New Speeds, Deterministic Networking, and Power over Everything! Your Instructors Today Peter Jones and Dave Zacks Peter is a Software Principal Engineer, and has been with Cisco over 10 years. Peter works on system architecture (ASIC, hardware & software) for Cisco Campus switching, as well as standardization of 2.5G / 5G BASE-T Ethernet as NBASE-T Alliance chair and in IEEE Dave is a Distinguished System Engineer, and has been with Cisco for 16 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 the evolution of Ethernet a passion we hope to share with you via this presentation! Peter Jones Principal Eng. Dave Zacks Dist. Sys. Eng.

Zeus Kerravala, Founder and Principal Analyst, ZK Research How Will ac Affect Your Wired Network? - July Code} As DX demands that enterprises rely on a broad set of connected devices and network applications over wired and wireless networks, network access infrastructure must evolve to keep the digital enterprise running. IEEE 802.3bz has the potential to help enable the digital enterprise to use not only WLAN but also wired connectivity to its highest potential while deriving maximum value from the cable plant. Nolan Greene, senior research analyst, IDC Network Infrastructure group The Newly Ratified IEEE 802.3bz Ethernet Standard: What Enterprise IT Needs to Know December Despite the limited availability of products, market shipments of NBASE-T surged in the second half of As merchant silicon-based products come to market, we expect adoption to accelerate, and have raised our 2017 forecast to surpass five million ports. Concurrently, the transition to ac Wave 2 Access Points is occurring faster than we previously predicted and is on track to be complete by mid Clearly, Enterprise users are hungry for multi-gigabit bandwidth to support traffic from their wireless devices.
