    • What is Cloud Computing?Copyright © 2011 LOGTEL
    • Definition  Wikipedia - a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them.  Academic (simple) - provide on-demand resources or services over a network, often the Internet, with the scale and reliability of a data center.  Mine – distributed mainframe, reachable from any device connected to the internetCopyright © 2011 LOGTEL 10
    • Oracle definition ;-) “...we’ve redefined Cloud Computing to include everything that we already do... I don’t understand what we would do differently ... other than change the wording of some of our ads.”  Larry Ellison, CEO, Oracle (Wall Street Journal, Sept. 26, 2008)Copyright © 2011 LOGTEL 11

    • Networking of Information (NetInf) The traditional role of networking has been to interconnect remotely located devices like computers or telephones. This function is increasingly recognized to be ill-adapted and inadequate for the information-centric applications that currently generate the vast majority of Internet traffic. In 4WARD we take a different approach, instead of the node-centric paradigm, we adopt an information-centric paradigm. In this paradigm, the communication abstraction presented to applications is based on transfer of application data objects instead of the end-to-end reliable byte- stream used by the majority of applications today.Copyright © 2011 LOGTEL 94

    • OpenFlow Switching : how it works? OpenFlow is based on an L2-L4 switch, with an internal flow-table, and a "standardized" interface to add and remove flow entries. New actions can be done on packet. OpenFlow Control Plane Large modifications of fields. Controller Routing on new criteria : L4, mix Define network slice on flow criteria … OpenFlow New routing protocol : multipath, load-balancing Protocol SSL Data Plane Flow tableOpenFlow is implemented byseveral vendors OpenFlow-enabled Layer 2-4 Switch Matches subsets of packet header fields Switch Eth VLAN IP TCP Port MAC ID
    • Standardisation in IETF IETF : new Programmable Network (Software-Driven Network)  Software-Driven Networks : to enable programmatic automation of configuration, management, monitoring, accounting/data mining of networks  Use cases: Bandwidth On Demand, Data center (Application-network information), Cloud bursting (Private/Public) IETF WG ForCes: started since 2002, but hardly active now  Objective: to standardize open, programmable distributed network architecture including description of the functional model of a Forwarding Element and the specification of the protocol for communication between control and forwarding plane in the router.  Standards: FoRCES working group has produced several RFCs for requirements , architecture framework, Protocol description, Forwarding Element Model and MIB for control-data plane interaction on top of transport layer. NETCONF/NETMOD:  provides a XML-based solution for network device configuration. It has been in wide-deployment (IP, LTE…)  it supports server-to-client configuration, but not client-to-server alarms or feedback.

    • CCT: NetworkingNetwork:• Gigabit to external network• Gigabit among compute nodes, head nodes.• 10 Gigabit among storage nodes• Flat topology• Racks have 4 HP ProCurve 2650 switches, connecting to 2 ProCurve 5412zl switches for the testbed.• Compute nodes have 2 NICs, connected to each 5412zl switch
    • Challenges to Network InnovationInnovation in the network is lagging. Why? • Proprietary Network Hardware • Incompatibilities between vendors • Network switch hardware and software in a black box • Too dangerous to experiment on production networks • Too expensive to test deployments • Hardware vendors implement features only for revenue
    • Software Defined NetworksIt is helpful to abstract servers using virtualmachines.We can apply a similar abstraction to networksthemselves.We would like to be able to programmaticallyconfigure and define networks.
    • Benefits of SDN Abstraction• Unity in conceptualizing pieces of the network.• One comprehensive view with which to monitor and control the network• Separate job of configuring the network from the job of defining and enforcing policy.
    • SDN and the Cloud• Hide physical complexity• Manage, on-demand virtual networks• Sustain multiple concurrent virtual networks• Provide resilience and flexibility with physical modifications to the network• Automated scaling
    • Barriers to SDNNetwork hardware companies do not want toexpose access to hardware.We must rely on what features the vendorsprovide and the way they are provided.There is a lack of consistency in what vendorsprovide and in the definitions of features.
    • OpenFlowOpenFlow is an API to the forwarding plane of thenetwork hardware.It separates the control function from the hardwareinto software controller servers.Any switch implementing the OpenFlow API can beprogrammatically operated by a separate server.Network hardware supporting OpenFlow ships withOpenFlow firmware.
    • SDN with OpenFlowOpenFlow-enabled switches and routers are configured byOpenFlow controllers.OpenFlow controllers can be simple Python servicesconnected using secure protocols.• Administrators can capture a complete topology of the network from a single controller.• No matter what vendor hardware or software, if the unit supports OpenFlow, the hardware can be abstracted.• Users could be granted permission to define circuits without the aid of IT support.• Compromised nodes can be detected and isolated.
    • Examples of OpenFlow Use Cases• NEC ProgrammableFlow – Virtualized Physical Network – Automatic Optimization of Network Resources – Alternate route finding for end-to-end reliability• Juniper Junos SDK – Added OpenFlow application to SDK – Customers can implement their own features• Deutsch Telekom – Energy-aware server provisioning and consolidation• Verizon – Deliver bandwidth-on-demand between data centers – Shape Traffic for long-lived flows, avoiding full algorithm
    • Open Networking Foundation“Founded in 2011 by Deutsche Telekom, Facebook,Google, Microsoft, Verizon, and Yahoo!, the OpenNetworking Foundation (ONF) is a nonprofitorganization whose goal is to rethink networkingand quickly and collaboratively bring to marketstandards and solutions. ONF will accelerate thedelivery and use of Software-Defined Networking(SDN) standards and foster a vibrant market ofproducts, services, applications, customers, andusers.” — opennetworkingfoundation.org
    • ONF VisionWith the advent of cloud computing, ONF believesthe line will continue to blur between the computerand the network.Network innovation must keep pace with demands.The Open Network Foundation aims to create “themost relevant SDN standards.”(Mission Assurance will depend on both the agilityand security of the network.)

    • NAAS Major Services • NAAS Web Service Interface: Simple Object Access Protocol (SOAP) service that exposes user authentication and authorization functions to all state nodes. It is the entry point for all service requests • Network Authentication Service: This is a subsystem for verifying subject (user or machine) identity • Network Authorization Service: This component is for entitlement management. Authorization is typically role- or policy-based. It must be flexible so that a variety of factors can be part of the decision to grant or deny access to specific resources • User Identity Management: This component is responsible for registering users, removing users, and modifying user profiles • Policy Management: The component allows administrators to create or modify rules or policies for resource access • Vulnerability Management: This component tracks instances of security breaches and generates reports that contain specific information about vulnerability and actions taken. A good vulnerability management system helps to prevent security problems from recurring • Network Certificate Authority: This component issues and manages certificates used for secure socket layer (SSL), encryption, and signature • Public Key Management: This component allows users to locate and validate public keysCopyright © 2011 LOGTEL
    • USN - Ubiquitous Sensor Network  USN is a conceptual network built over existing physical networks which makes use of sensed data and provides knowledge services to anyone, anywhere and at anytime, and where the information is generated by using context awareness.  USN utilizes wireline sensor networks and/or wireless sensor networks (WSNs).  WSNs are wireless networks consisting of interconnected and spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions (e.g., temperature, sound, vibration, pressure, motion or pollutants) at different locations.  Sensor networks is made by the capture and transmission of collected sensed data to designated application systems.Copyright © 2011 LOGTEL 147
