Policy-Driven Infrastructure: Separating User Intent from Configuration Procedures

Listen to the Podcast

January 28th, 2015

policy_driven_infrastructure_mike_sandeepThe focus on separating user intent from infrastructure is an important new insight into how cloud environments should be run.  To drive forward this approach, Group-Based Policy is currently being developed for both OpenStack and OpenDaylight open source projects. Mike Cohen, Director of Product Management and Sandeep Agrawal Senior Marketing Manager, both of whom work at Cisco Systems join me to talk about Group-Based Policy or using intent to manage infrastructure.

CiscoProgrammingEnvironmentNexus9000BradleyWongToday’s networks are restricted to configuration programming via CLI, but what if applications can call upon network resources automatically or if application developers are provided access to network state, topology, performance and other information? How might applications change and user experience improve? How may a networking programmable environment enable automated provisioning, orchestration and management? Could a programmable network enable a new era of IT and an industry of network aware applications just when the Internet of Things is starting to emerge? The Cisco Nexus® 9000 product line provides a wide range of programming options through an enhanced version of the Nexus Operating System (or NX-OS) that ranges from APIs to direct programming via its built-in Linux BASH environment, RPC, RESTful APIs, JSON, Python etc. I’m joined by Bradley Wong, Distinguished Engineer, Technical Marketing at Cisco, as we review the Cisco Nexus programming environment, its programming options provided to developers, use cases and potential industry impact.

Nexus9000ProgrammingEnvironmentDemonstratedLillianQuanTo understand the depth of the Cisco Nexus® 9000 programming environment, Lillian Quan, Technical Marketing Engineer at Cisco, demonstrates the richness of this new platform. We start with standard CLI comments then move to the Nexus API environment that generates JSON or XMP code. We then utilize this code to demonstrate automation of repetitive network engineering task via Splunk and real-time graphic of network data via Graphite to create a NOC dashboard. After watching this video, network engineers will want to enroll in a Linux course while DevOps will finally be able to use familiar tools to access network data and information.

Cisco Nexus® 9508 Sets New High Performance Latency Test Result Record of 1.6 to 3.5 microseconds Spine Switch Populated With 288-40GbE Ports

Watch the Video

November 6th, 2013

CiscoNexus9508LatencyTestResultBradleyWongWhile most companies announce products long before first customer ship with long road maps of when product features are available, Cisco’s Nexus® 9508 is ready now. The independent and open industry Lippis/Ixia team test the Nexus® 9508 at 288-40GbE capacity for layer 3 unicast plus IP multicast latency and congestion management via RFC 2544, 3918 and 2889, respectively. This test is a new industry record as no other data center switch has been tested at 288 40GbE ports. What are really impressive are the results and the engineering achievement of the Cisco team. I’m joined with Bradley Wong, Distinguished Engineer, Technical Marketing, at Cisco, as we review the Cisco Nexus® 9508 test methodologies and results.

August 11th, 2013

By Lippis/Ixia

The Cisco Systems Nexus® 3548 is the fastest ToR switch that we have tested at these Lippis/Ixia tests by a large amount. The Nexus® 3548 forwards packets in slightly more than half the time of the next fastest switch we have tested! That is, it’s nearly twice as fast as the fastest previous switch tested. The Nexus® 3548 is also the fastest IP multicast forwarding switch we have tested to date, being able to forward packets some 62.5% faster than the previously fastest ToR switch tested. The Nexus® 3548 is an engineering achievement for both its raw packet processing performance, congestion management and value added Algo Boost and Warp Mode technology.

IBM Software Defined Network for Virtual Environments Network Virtualization for the Network You Have

Get the White Paper

June 24th, 2013

by IBM

Into a world populated by position papers, statements of direction and technology roadmaps, IBM introduces its latest solution that supports the next major advance in enterprise communications, which is Software Defined Networking (SDN). SDN is a new network paradigm that separates network control logic from the underlying network hardware. IBM is putting it to work with IBM SDN for Virtual Environments (SDN VE), a network overlay solution that supplies a complete implementation framework for network virtualization. In short, SDN VE software supplies a core component of SDN architecture, which is fully deployable for data center expansion. The purpose of this white paper is to provide an overview of the functions and benefits of SDN VE, and outline the steps to implementation.

Cisco Enhances VXLAN: Eliminates IP Multicast Requirement, integrates virtual services via vPath plus connects to legacy networks

Listen to the Podcast

May 27th, 2013

Han_Yang_Cisco_Enhances_VXLAN_Eliminates_IP_Multicast_Requirement_integrates_virtual_services_via_vPath_plus_connects_to_legacy_networksCisco introduced enhancements to its VXLAN implementation in the Nexus 1000V virtual switch that overcomes the requirement for IP Multicast. In addition Cisco is integrating vPath to VXLAN for service insertion that stitches virtual services into VXLAN overlay tunnels. Network services might include virtual firewalls, application delivery controllers, WAN optimization, network monitors, etc. A final VXLAN challenge that network teams are facing is how to integrate VXLAN into legacy networks and with existing physical networks, appliances and the enterprise WAN. We’ll hear if Cisco has any solutions to get around this issue as well. Han Yang of Cisco joins me to discuss VXLAN, without multicast and with vPath, and how it can be used to deploy virtual network overlays.
