1 Network Virtualization: Recent Developments Overview Washington University in Saint Louis Saint Louis, MO CSE 770 Networking Research Seminar at WUSTL January 28, 2013 These slides and audio/video recordings are available at: 1 1. Virtualization: Why, How? 2. Recent Networking Virtualization Technologies 3. Software Defined Networking 4. Our Research: Open Application Delivery Note: References to sources are either on the same slide or at the end. 2 Virtualization of Life Internet Virtualization No need to get out for Office Shopping Entertainment Education Virtual Workplace Virtual Shopping Virtual Education Virtual Sex Virtual Computing Why Virtualize? 1. Sharing: Break up a large resource Large Capacity or high-speed 2. Isolation: Protection from other tenants 3. Aggregating: Combine many resources in to one 4. Dynamics: Fast allocation, Change/Mobility, load balancing 5. Ease of Management Cost Savings 6. Mobility for fault tolerance 10Gb 3 4
2 Storage: Virtualization in Computing Virtual Memory L1, L2, L3,... Recursive Virtual CDs, Virtual Disks (RAID), Cloud storage Computing: Virtual Desktop Virtual Server Virtual Datacenter Thin Client VMs Cloud Networking: Plumbing Virtual Channels, Virtual LANs, Virtual Private Networks Networks consist of: Hosts - L2 Links - L2 s - L2 Networks - L3 Links - L3 Routers - L3 Networks L4 Transports L5 Applications Each of these can be/need to be virtualized Quick review of recent technologies for network virtualization 5 vnics Each VM needs its own network interface card (NIC) Hypervisor p = Physical v = Virtual M = Machine pm vm1 vnic1 v vm2 vnic2 p 6 vm1 vnic1 vm2 v vnic2 vnics (Cont) pm vm1 vnic1 pm v p 1. VM vendors: S/W NICs in Hypervisor w Virtual Ethernet (VEB)(overhead, not ext manageable, not all features) 2. NIC Vendors: NIC provides virtual ports using Single-Route I/O virtualization (SR-IOV) on PCI bus 3. Vendors: provides virtual channels for inter- VM Communications using virtual Ethernet port aggregator (VEPA): 802.1Qbg (s/w upgrade), 802.1Qbh (new switches) 7 vm2 Hypervisor vnic2 pm vm1 vnic1 VEPA vm2 vnic2 Port Extension Multiple physical bridges to make a single virtual bridge with a large number of ports Easy to manage and configure IEEE 802.1BR 8
3 Multi-Tenants Each tenant needs its own networking domain with its VLAN IDs Server 1 Server 2 VM1-1 VNI 22 VM1-2 VNI 34 VM2-1 VNI 34 VM2-2 VNI 74 Multi-Site Better to keep VM mobility in a LAN (IP address changes if subnet changes) VM1-3 VNI 74 VM1-4 VNI 98 VM2-3 VNI 98 VM2-4 VNI 22 Hypervisor VTEP IP1 L3 Networks Hypervisor VTEP IP2 1. Virtual Extensible Local Area Networks (VXLAN) 2. Network Virtualization using Generic Routing Encapsulation (NVGRE) 3. Stateless Transport Tunneling Protocol (STT) Network Virtualization over L3 (NVO3) group in IETF Solution: IP encapsulation Transparent Interconnection of Lots of Links (TRILL) 9 10 Clouds and Mobile Apps Global Virtual Net August 25, 2006: Amazon announced EC2 Birth of Cloud Computing in reality (Prior theoretical concepts of computing as a utility) Web Services To Drive Future Growth For Amazon ($2B in 2012, $7B in 2019) - Forbes, Aug 12, 2012 June 29, 2007: Apple announced iphone Birth of Mobile Internet, Mobile Apps Almost all services are now mobile apps: Google, Facebook, Bank of America, Almost all services need to be global (World is flat) Almost all services use cloud computing Networks need to support efficient service setup and delivery 11 Application Delivery Evolution Single Server Data Center 3. Global Clouds 3. Global Clouds Load Balancers Global Internet 12 SSL Off loaders Need to make the global Internet look like a data center

Controller can be complex Can use powerful CPUs Lots of cheap switches = Good for large datacenters Ref: [MCK08] ``OpenFlow: Enabling Innovation in Campus Networks," OpenFlow Whitepaper, March Element Element Control OpenFlow Data Element Element Centralized vs. Distributed Fully centralized is not scalable. Fully distributed is not manageable. Hierarchy 16
5 Development 2: Standardized Abstractions The routers are expensive because there is no standard implementation. Every vendor has its own hardware, operating/ management system, and proprietary protocol implementations. Similar to Mainframe era computers. No cross platform operating systems (e.g., Windows) or cross platform applications (java programs). OSPF BGP DHCP Network Operating System Proprietary fast forwarding hardware Ref: 17 Cisco IOS Juniper JUNOS Example: PC Paradigm Shift Computing became cheaper because of clear division of hardware, operating system, and application boundaries with well defined APIs between them Virtualization simple management + multi-tenant isolation Scientific Business Batch OS360 Operating System IBM 360 HW, Storage, MSOffice OpenOffice DOS Windows Intel AMD ARM 1998 VM1 VM2 VM3 Hypervisor Physical HW LINUX Software Defined Networking Layered abstractions with standardized APIs Enterprise 1 Enterprise 2 Enterprise 3 Multicasting Mobility App1 App2 Applications Northbound SDN s Layered Abstraction ASP1 ASP2 ASP3 OpenADN OpenADN OpenADN Net App1 Net App2 Net App3 Application Level Control (ASP) Network Level Control (ISP) Network OS1 Network OS2 Network OS3 Network Virtualization HW HW HW HW Ref: 19 Network OS Virtualization Network OS1 Network OS2 Network OS3 Network OS Network Virtualization Virtualization Southbound OpenFlow HW HW HW SDN provides standardized mechanisms for distribution of control information 20

Commodity hardware Lots of cheap forwarding engines Low cost Programmability Customization Those who buy routers, e.g., Google, Amazon, Docomo, DT will benefit significantly Tsunami of software defined devices: Software defined wireless base stations Software defined optical switches Software defined routers 22 Potential Life Cycles of Technologies MPLS Industry Growth: Formula for Success Number of Companies Innovators Startups Technology Differentiation Big Companies Manufacturing Price differentiation SDN Research Hype Dis illusionment ATM Success or Failure Time New Consolidation Stable Time Entrants Growth Paradigm Shifts Leadership Shift Old market leaders stick to old paradigm and loose Mini ComputersPC, PhoneSmart Phone, PCSmart Phone 25 26

Edge devices only. Core network can be current TCP/IP based, OpenFlow or future SDN based 2. Coexistence (Backward compatibility): Old on New. New on Old 3. Incremental Deployment 4. Economic Incentive for first adopters 5. Resource owners (ISPs) keep complete control over their resources Most versions of Ethernet followed these principles. Many versions of IP did not. 28 Summary References 1. Cloud computing Virtualization of computing, storage, and networking Numerous recent standards related to networking virtualization both in IEEE and IETF 2. Recent Networking Architecture Trends: 1. Centralization of Control plane 2. Standardization of networking abstractions Software Defined Networking (SDN) 3. Most networking devices will be software defined 3.
