IBM Programmable Network Controller

  1. 1. IBM Systems and TechnologyData Sheet IBM Programmable Network Controller Harnessing Software Defined Networking and OpenFlow to build agile data centers Enterprises, trading centers and network operators are looking for ways Highlights to simplify, streamline and virtualize their data centers. Software Defined Networking (SDN) with OpenFlow is emerging as a compelling way to Easily and cost-effectively deploy, ●● ● ● build fast, agile and intelligent networks. Data flow control is abstracted customize, control, monitor and manage scalable and agile network infrastructures from static individual switches to dynamic programmable network-level control. Administrators can quickly create and control virtual networks ●● ● ● Support virtualized, dynamic workloads in for each application environment or network service. They can scale the data center with an OpenFlow-based physical network infrastructure highly virtualized application infrastructures, multi-tenant networks on public or private clouds. ●● ● ● Centrally configure and enforce secure multi-tenant networks The IBM Programmable Network Controller (IBM PNC) provides Centralize control of the network for ease ●● ● ● an OpenFlow-based network fabric with centralized control of network of configuration, management and quick response to changing network state for flows and unlimited virtual machine (VM) mobility—implemented in improved and simplified network opera- enterprise-class software.

The IBM PNC helps provide a highly reliable, ●● ● ● Increase overall system reliability and edge-to-edge system network fabric that can be defined for multi-tenant availability with advanced network awareness and automation environments. Granular policy enforcements ensure secure isolation across multiple tenants. Administrators can use the IBM PNC to attach policies that direct overall network operations, saving management time and helping to ensure that data center system and network deployments are aligned with business strategy. By implementing the network fabric’s packet forwarding control logic in a software-defined controller, the IBM PNC centralizes the conventional packet forwarding logic that is traditionally embedded in the control

Unlike conventional switches that are staticallyconfigured once and then must be configured whenever appli-cation workloads change or traffic patterns fluctuate, adminis-trators can use the IBM PNC to dynamically direct trafficacross multiple switches throughout one or more data centers.Simplified, highly available networksThe IBM PNC centralizes the control and configuration of theentire network. Global real-time visibility of the entire networkmeans that all the links in the network can be active at all times.By contrast, traditional networks running Spanning TreeProtocol (STP) render many links unusable—and have slowernetwork convergence time when a device goes offline.The IBM PNC supports a feature called “Equal CostMultipath” (ECMP), which defines the physical path that traffic Automated networks supporting dynamic workloadstakes across the network, using path policies and distribution of The IBM PNC uses the OpenFlow protocol to move the com-traffic across equal cost links. plex, error-prone and vendor-specific command line interfaces (CLIs) into an open and standardized programmable interface.Secure multi-tenant networks OpenFlow works with data center switches from various ven-Virtual application networks allow each tenant to define and dors that comply with the OpenFlow standard, and provides:control a customized policy-based Layer 2 or Layer 3 network.Inter-tenant isolation effectively maintains a secured slice of the ●● ● Automated topology discovery of all devices in the networkunderlying physical network. ●● ● Point and click virtual network design ●● ● Automated movement of networking policy when a virtual●● ● Network isolation allows network segments to be configured machine (VM) or endpoint moves physical locations centrally and enforced throughout the network without ●● ● Application programming interface (API) that allows third switch configuration party systems to make on-demand calls to the API to create,●● ● Virtual networking provides virtual bridge and router edit and delete virtual networks, as well as to add and remove functions, and virtual filters can define Access Control policies Lists (ACLs) with various degrees of complexity ●● ● Flow migration allows flows to be moved off of devices without interrupting network sessions 2
