  14. 14. 1How to reduce installation costs ?  Today to deploy and operate video applications is expensive: manual intervention, skills required, etc…  Medianet can streamline certain deployment processes of video end-points by enabling the network to automatically recognize, configure, and provision the devices. Minimize deployment time and Configuration processes through automation and lowering the need for expertise. © 2010 Cisco Systems, Inc. All rights reserved. Cisco Public 14
  15. 15. How to increase flexibility without loosing 2track of device location ?  Complexity increases the likelihood for loss of equipment, mis-configuration of devices, and security issues.  Medianet provides location information as well as a baseline security level, allowing equipment to be easily moved across the network. Keep track of device location and exploit a whole new level of flexibility Click here for more detail © 2010 Cisco Systems, Inc. All rights reserved. Cisco Public 15
  16. 16. Medianet 2.1 – Auto-configurationSimplify deploymentThree Major Components of Auto-configuration: • Device Announcement via CDP or Mac Range • Auto Smartports for device detection and Specific Macro application • Location Information. Setting up and sending location using IOS based feature and propagated it to the endpoint. Access Switch can Auto-configure those parameters using Auto Smartportsbased on CDP or Mac range. Endpoint can provide information to the Network using MSI (Medianet Service Interface). © 2010 Cisco Systems, Inc. All rights reserved. Cisco Public 16

  18. 18. Is my network ready for the deployment 3of… ?  There is currently no method for realistically assess what will happen at the moment of deployment, even thought guidelines and predictions can help.  With Medianet an operator can simulate real video application traffic and assure the network is ready for what is being planned for implementation. Ensure the content/media can delivered with the expected quality of experience to your users. © 2010 Cisco Systems, Inc. All rights reserved. Cisco Public 18
  19. 19. How can I be sure that an upcoming 4broadcast will be OK ? Estimations can provide a good starting point, however currently there is no mean of precisely predict what would happen at the moment of an event and take corrective actions right away. Medianet allows an operator to proactively assess and simulate a network test for its ability to handle specific events. Medianet lets you simulate events before they ocurr, leaving enough time to fine tune if necessary. Click here for more detail © 2010 Cisco Systems, Inc. All rights reserved. Cisco Public 19
  20. 20. IP SLA Video Operation (VO) Coming 1H‟2011Embedded Traffic Simulator  IPSLA known in industry for jitter, ICMP, etc. probes  Most probes measure experience without affecting user traffic (hopefully)  Need traffic to stress test network  IPSLA VO provides  Realistic representation of arbitrary video (RTP) traffic  Packet sizes, burstiness, traffic rate, etc.X  pre-packaged profiles:  IPTV, Video Surv, CTS X  Extensible via data file  Custom profile generation from packet capture © 2010 Cisco Systems, Inc. All rights reserved. Cisco Public 20
  21. 21. IPSLA Video Operation • Convenient for pre-deployment assessment, pre-event testing and post-event troubleshooting. • More bandwidth needed?

  23. 23. Dynamic Monitoring with Mediatrace Let mediatrace do the walking for you!  Mediatrace discovers and queries L2 and L3 nodes along a flow‟s path  Gathers system resource, interface and flow specific (perf-mon) stats For performance monitor: dynamically configures monitoring policy (if needed) 5-tuple + intervals etc. match static policy).  Consolidates information into a single screen  Allows for easy comparisons of device behavior Which interface dropping packets? Where is DSCP getting reset?  Can be requested by remote device  Automatically (based on thresholds) via EEM script Built into MSI applications, operator or automatic triggering © 2010 Cisco Systems, Inc. All rights reserved. Cisco Public 23
  24. 24. Mediatrace Components Requestor – origin of request Video end system, NMS, same node as initiator, remote router/switch Initiator - injects the trace Responder - sends data back to initiator Multiple types of data requests Hops – hop discovery System – system information Performance monitor – enables perf-mon, then collects data Multiple execution formats Poll – minimal config, run from IOS exec Session – flexible configuration, allows for periodic, recurring requests and historyflow Initiator + responder responder requestor © 2010 Cisco Systems, Inc.

  29. 29. How can I scale video deployment? 7 Maximizing network resources usage without compromising performance is highly difficult due to the specific requirements of video traffic and requires a lot of network design effort. Medianet can leverage technology that attempts to utilize all possible paths on the network and combine that with advanced resource reservation and admission control. Reduce over-provisioning strategies to scale video deployment. Make the best of your existing network. Click here for more detail © 2010 Cisco Systems, Inc. All rights reserved. Cisco Public 29
  30. 30. Introduction Network Traffic vs. Network Capacity May not always possible Not OK to “squeeze” Voice & OK to “squeeze” Data traffic to over-provision Video traffic; they’re inelasticNetwork TrafficNetworkCapacity Over-provisioning Congestion Control Admission Control Adjust network capacity Adapt elastic traffic flows Reject traffic flows that to accommodate peak to their share of network exceed network capacity traffic capacity or violate policy © 2010 Cisco Systems, Inc.

  31. 31. Medianet - Resource Reservation and Control Predictable and controlled QoE in the event of resource contention Service reservation indicative of dynamic application session requirements Intelligent use of links based on capacity & bandwidth is not the only metric Sanctioned applications given preference Event detected, camera requestsCamera additional 1Mbpsrequests 2Mbps bandwidthbandwidth MPLS Internet © 2010 Cisco Systems, Inc. All rights reserved. Cisco Public 31
  32. 32. How can an operator maintain that the network isconstantly optimized for video applications ? 8 Before medianet, the network was neither media nor application aware. The goal of Medianet is to identify what are the requirements of each video session/application, allowing the operator to decide how to optimize media end-to-end An endpoint, media and network aware architecture will allow custom business policies to be applied and also aids as where to invest for optimization.
