3 Agenda Coffee & Intros Brave New World Software is Hot 30 years of SDN Hardware is cool SDN applications 3

4 Have you heard Software is Hot

5 it s a brave new world Over the next 5yrs, network programmability (a.k.a SDN) will change the landscape of enterprise & SP networking SDN will invade all pillars of modern enterprise networks, WAN, Campus, Remote Access, Security, Mobility, Data Center (more acronyms like SDP, SDDC, SDS, ect ) It is unavoidable This is not an Evolution, not a Revolution, it is an Everlution 5

6 How many of you have an SDN project or are evaluating some form of SDN rollout in the next 12 months? 6

7 Software-Defines Networking (SDN) The What Software defined networking (SDN) is an approach to building computer networks that separates and abstracts elements of these systems. 7

8 Software-Defined Networking (SDN) Common SDN Topologies *ISV & competitive targets Tight coupling of HW & SW Loose(r) coupling of HW & SW Logical/Overlay Networks APIs Controller Virtual Overlay Custom+ 8

9 Preferred Hybrid SDN topology For those with commitment issues *or* just good business decision makers Applications Classic SDN topology + Control Plane Controller Overlays can fit here as well onepk, OpFLex, CLI 9

10 The Cisco Approach Hybrid, Flexible, Programmable at all layers Application Environment Collect Network Intelligence at all layers Management & Orchestration Network Services Overlays/Virt Control Plane Forwarding/Data Plane Transport Underlay/HW /SDN Focus on value and experience 10

11 Programmable Interfaces Mapped to use case groups and functions Configure & Operate Provisioning/Configuration & NETCONF Operations centric use cases YANG (de-facto) standards compliance Open source and 3 rd party off-the-shelf Cisco tools Python API REST API API modeled around device data/capability Built into Network OS Device Extension Traffic steering & packet capture/manipulation use cases Real time event handling Improved AppDev experience Strong typed language API Built into Network OS DevOps Integration Provisioning/Configuration and Operations centric use cases Custom fit API into Open Source/3rd party/custom controller OpFlex Customer choice for device interfaces Runs in a container independent rev cycles

12 Triage support with my hosting vendor, commodity hw provider, and dev-ops app writer where do I sign??

13 Overlays are burning up the charts

14 Why are Overlays white hot? So what is the benefit we have seen network virtualization before Overlay topologies can be created manually or programmatically (ding!), deployed, and destroyed without changing the underlying physical network (underlay) The Overlay method of SDN would use a centralized control-plane (controller) and offer multi-vendor support on the underlay (assuming certain characteristics are met by the hardware, like OpenFlow, vxlan, ect..) The Overlay could be completely virtual leveraging technologies like softwarebased vswitches (OVS) and virtual gateway appliances. (what about my baremetal?) The characteristics of an Overlay share common principals with VLANs, MPLS, and VRFs ect the original game changers 14

15 Overlays, Underlays, and Tunnels Oh My Overlay enabling protocols for reference : QinQ IEEE (802.1ad) SPB IEEE (802.1aq) VNTag IEEE (802.1BR) TRILL IETF (RFC) OTV IETF (Draft RFC) MPLS IETF (RFC) VPLS IETF (RFC) vcdni VMware (none) STT IETF (Draft) OpenFlow ONF (Draft) NVGRE IETF (Draft) VXLAN IETF (Draft) GENEVE IETF(Draft) *MS/VMware/RH Overlay 2 15

16 Overlay Edge Topologies Overlay/tunnel EP Network Overlay (Phys) Host Overlay (Virt) Hybrid Overlay technology mapping technology mapping technology mapping VPNs, VRF, loop detection, OTV, VXLAN, VPLS, MPLS, MT FP vsw-to-vsw VXLAN, NVGRE, STT VXLAN, NVGRE Metal-to-VM Push for open standards Phys workloads VM VM VM VM VM VM x86 host x86 host 16

17 So who is driving this ship?

18 ISV Marketing Teams Tongue firmly planted in cheek, we love our ISV partners Software-defined anything is cool because all we do is write software Minor entry barriers, instant buzz Show me the VC & M/A money!!! We want you to view your hardware like this so you have more $$$ for licenses* 80-proof *The Paper Towel Model 18

19 My favorite SDN Hype quote I think IT shops are looking at Amazon and Google and Facebook and saying, We need to be more like them. A primary driver is an agility requirement. IT has realized that, while it can do wonderful things on the compute side in terms of spinning up servers in seconds, the operational model of networking is still very manual, very static, very brittle. That s the primary problem we re solving. Along with that comes operational efficiency.

21 Software is Hot The ONF describes SDN architecture as NB application API Directly programmable: Network control is directly programmable because it is decoupled (SDN Value) from forwarding functions. Agile: Abstracting control from forwarding lets administrators dynamically adjust networkwide traffic flow to meet changing needs. Centrally managed: Network intelligence is (logically) centralized in software-based SDN controllers that maintain a global view of the network, which appears to applications and SB Infra API policy engines as a single, logical switch. onepk, CLI GENEVE (SDN Turf War) Programmatically configured: SDN lets network managers configure, manage, Stay tuned, secure, and optimize network resources very quickly via dynamic, automated SDN programs, OpFlex which they can write themselves because the programs do not depend on proprietary software. Open standards-based and vendor-neutral: When implemented through open standards, SDN simplifies network design and operation because instructions are provided by SDN controllers instead of multiple, vendor-specific devices and protocols

22 How OpenFlow works Just the basics please 1. Openflow Controller/Code 2. Northbound API (this is the real SDN value) 3. OpenFlow Agent 4. OpenFlow Protocol 22

23 OpenFlow Hybrid Ships in the night or Integrated OPENFLOW ONLY Data Data Data OpenFlow Processing Pipeline I N T OpenFlow defines two processing pipeline options OPENFLOW ONLY and OPENFLOW HYBRID Data Data Data OF or STD OPENFLOW HYBRID OF Processing Pipeline I N T STD Processing Pipeline 23

24 SDN Controller/Applications Quality Use Cases, Low-Hanging Fruit Network Tapping ( Cisco Matrix, ERSPAN) Policy based approach of mirroring production traffic to analysis tools with offthe-shelf switches Custom Forwarding (Traffic Steering, TIF, RfD) Per Flow Control Static or dynamic creation of business rules using a variety of parameters Network Segmentation (a.k.a. Campus Slicing) Network Partitioning at higher levels of granularity 24

25 OpenFlow Features & Timeline Dec 2009 Feb 2011 Dec 2011 Summer 2012 Now+ v1.3.1 v1.5 OFv1.0 Single Table L2, IPv4 focused matching OF v1.1 OF v1.2 OF v1.3. v1.3.1 Multiple Tables MPLS, VLAN matching Groups: {Any-,Multi-}cast ECMP IPv6 Flexible-length matching 802.1ah PBB Multiple parallel channels between Switch and Controller Negotiation TLVs OF v1.4 Optical support Improved extensibility (TLVs) Enhanced rule mgt Enterprise grade features complexity So can we really decouple the hardware form the software?? If my value depends on what SB feature sets my HW supports 25

26 OF- Support Considerations OpenFlow is a low/machine level interface (i.e., a driver ) and is a moving target OpenFlow doesn t help with application, policy and flow composition and orchestration, or hybrid network V&V, cloud Distributed state and topology; the network isn t what you think it is Many changes are ephemeral in the SDN world (good for testing, odd for CC/auditing) Software is immature/maturing; controllers and switches are as well 26

27 Of course Cisco is leading the SDN charge as well

28 Cisco Controller party We have 4 and that s too many, we know APIC-EM OpenDaylight OpenDaylight (ODL) Open Source SDN controller/project under the Linux Foundation, community supported, Free Cisco XNC Commercial Cisco offering of the ODL controller, Cisco supported, Roadmap evolving, Cisco leadership has expressed concern about overlap/consistency in messaging APIC-EM Purpose-built ease of use SDN controller, built for investment protection, FREE smartnet, REST NBI but programming not required (OpFlex) Enterprise Customers with Few to No Programming Resources that desires a Commerciallysupported solution that preserves existing investment and doesn t require HW/SW upgrades APIC (DC) ACI Policy Authority/Controller for ACI Fabric deployments (OpFlex) 28

29 So OpenStack that s SDN right?

30 What about OpenStack 3 parts cloud, 1 part SDN maybe Plug-in based NaaS support, OF, Nexus (phys/virt), OVS overlay 1 30

31 Is SDN a solution with no problem?

32 How do we prepare?

33 Embrace, Engage, Prepare The 7 P s of IT apply as usual Consider your hiring criteria when making staffing decisions Look for programming/automation experience, touch, on resumes and CVs Add some of this philosophically into job descriptions, nice to haves Re-examine in-house skills/talent and reach out to other teams Great oppty for inter-dept. collaboration and value creation, potential cross-training Tech/IT steering and adoption committee Increase your own acumen Lots of quality (marketing free) training available, like these for instance: Intro to Python Rice University/Coursera, Online Webinar, FREE (as in beer) Community Contributions: whomovedmycli NX-OS Python script repository on GitHub, simple to interpret, edit, test 33

34 Check this out SDN value creation

35 SDCS Application & User focused, Cisco end-2-end Joe (Client Services) Let s investigate realtime Using chat messages (xmpp), Joe can instantly view a network topology to Olivia XMPP/jabber With a custom/user-focused topology generated real-time, Joe can visualize Olivia s network health Olivia (BYOD User) I am having problems viewing the live corporate meeting Joe can initiate network monitoring or even adjust Olivia s network flow with a few clicks media stream media stream On-demand (on-click) device/user data populated from Cisco technologies like ISE, Mobility Services, Prime, MediaNet ect Now, imagine this as and add-on/extension to your existing Support Management system 35

39 Why Hardware is still Cool

40 Why Is Shaun So Excited About Hardware?

41 More then you probably thought! 41

42 I took the system to it s maximum potential -CLU 42

43 The Legendary Motorola/Freescale 68k Kicking butt since

44 Microprocessor Design Present Day general purpose Processor Designs CISC- Analogous with x86 RISC- Analogous with ARM VERY Flexible Processers, but SLOW 44

45 We NEED Speed for Packet Forwarding and Congestion Management

46 I Love ASICs 46

47 What exactly is an ASIC? An Application Specific Integrated Circuit is an integrated circuit customized for a particular use, rather than intended for general purpose use 47

48 Where Do ASICs Fit? ASICs form a foundational element within our technology stack The Data Plane (Where we want to go fast like Usain Bolt and avoid congestion) 48

49 The Network Cannot Run FAST without the right ASICs 49

50 Guess that ASIC didn t have good congestion management! 50

51 Cisco s Long History with Enterprise Switching Silicon (e) Cisco has a long and proud history of developing our own custom ASICs in Catalyst switches, spanning two decades of continuous innovation. 51

52 Network ASICs: Enterprise Silicon

53 Does one size fit all? Network ASICs while VERY fast have traditional been fixed Until NOW! 53

54 The Most Programmable Silicon Industry s leading hardware data plane and innovation, integrated into our SDN strategy 54

55 The Move to Programmability SDN provides programmability and flexibility in network deployments But traditional ASICs have fixed processing, and take a long time to develop for new features

56 ASIC Programmable Pipeline Packet Header Modify processing behavior without incurring re-spin 56

57 Unified Access Data Plane: Innovative Programmable ASIC UADP provides a highly advanced, programmable switching ASIC used in our Catalyst 4500 (Sup 8-E), 3850, and 3650 switches

58 We get it, Cisco Knows Switching. What about Routing?

59 Routing Evolution At one time it is was all about basic transport and pushing multiprotocol packets as fast as possible from A to B. We now have Security, Encapsulation, QoS, VoIP, Video, VPN, Wireless and Application Visibility considerations. Router> show clock *00:01: UTC Mon Mar n3tark_4451#show clock 14:02: EDT Wed May
