How to reduce installation costs ?1

How to increase flexibility without loosing track of device location ?2

Is my network ready for the deployment of XYZ ?3

How do I make sure hi-priority sessions have the

best Quality of Experience ?6

How can I scale video deployment?7

4 How can I be sure that the upcoming event will be OK ?

5 What if i need to understand why and where video

quality issues occurred?


How 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.

1

Minimize deployment time and

Configuration processes through

automation and lowering the need for

expertise.


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.

Medianet 2.1 – Auto-configurationSimplify deployment

Three 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).

Is my network ready for the deploymentof… ?

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.

3

Ensure the content/media can delivered

with the expected quality of experience to

your users.


How can I be sure that an upcoming broadcast 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.

IP SLA Video Operation (VO)Embedded 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.

pre-packaged profiles:

IPTV, Video Surv, CTS

Extensible via data file

Custom profile generation from packet capture

• Convenient for pre-deployment assessment, pre-event testing and post-event troubleshooting.

• More bandwidth needed? Deploy PfR?

• QoS needed?

• Fully integrated with IPSLA control and scheduling framework

• Extension to current IPSLA CLI and MIB interface to allow easy integration with NMS products

• Traffic is RTP: can use mediatrace and performance-monitor to do fault-isolation


How do I understand why and where video quality issues occurred?

Today Post Assessment of video quality issue is very difficult. Manual Process - Difficult to identify/retrieve accurate information - No global end to end view.

By taking into account end to end information, video monitoring in Medianet is able to detect what the issue is and where is it occurring. Details will be reported into a monitoring dashboard, simplifying the process of troubleshooting.

Target accelerating error detection for faster

problem resolution.

Dynamic Monitoring with Mediatrace

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

Let mediatrace do the walking for you!


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 history

Note: Data omitted for better readability.


How do I assure hi-priority sessions have the best Quality of Experience among all type of video streams ?

Today providing a global and flexible QoE is difficult, as most video applications are not network aware (and vice versa)

Medianet capable network:

Classifies the important video communication streams

Allocates network resources and priorities in a granular manner

Enhance Quality of Experience by providing

global, better and accurate resource/quality

allocation

How can I scale video deployment?

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.

Congestion Control

Adapt elastic traffic flows

to their share of network

capacity

Admission Control

Reject traffic flows that

exceed network capacity

or violate policy

OK to “squeeze” Data traffic Not OK to “squeeze” Voice &

Video traffic; they’re inelastic

May not always possible

to over-provision


Medianet - Resource Reservation and Control

MPLS

Camera requests 2Mbps bandwidth

Predictable and controlled QoE in the event of resource contention

Service reservation indicative of dynamic application session requirements

Event detected, camera requests additional 1Mbps bandwidth

Internet

Intelligent use of links based on capacity & bandwidth is not the only metric

Sanctioned applications given preference


How can an operator maintain that the network is constantly optimized for video applications ?

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

8

An endpoint, media and network aware

architecture will allow custom business

policies to be applied and also aids as where

to invest for optimization.

Cisco Innovations Leveraged for Video Deployments

Performance based Routing (PfR) and IP SLA

Video Monitoring Initiative

Core IP/MPLS Innovations and Focus Areas


What Is Performance Based Routing (PfR)?

Real-time Route Selection

Based on performance delay, loss, jitter, unreachable, mos, load and $cost

Embedded completely in Cisco IOS®

Has passive learning and monitoring component

Useful for baselining

Already uses IPSLA, NetFlow, NBAR on backend

Name change: OERPfR

IOS CLI will eventually migrate, accept both

In this presentation PfR term is used


IP SLAs Key Measurements

Measurements

Continuous and reliable: Providing a statistical end-to-end matrix of performance information

Jitter, packet loss latency, voice quality scores (MOS)

Per direction source to destination or destination to source

Per class of service to verify QOS for data, voice, and video

Latency to web servers, DHCP servers, DNS response times, TCP response time

Hop by hop measurements including jitter


Best Path Selection per Prefix/Application/DSCP for Two or More Paths

Core Network Video/Multicast Transport Options

Native IP multicast

Is used for Distribution, Contribution and mVPN applications

Simple and Scalable, has been in use for many years

MPLS multicast (Label Switched Multicast)

Can be used for Distribution, Contribution, and mVPN applications

P2MP-TE: Targets contribution applications that require route pinning and CAC

mLDP: Suitable for MP2MP mVPN applications. Can be used with or without TE FRR.

Live/Live Network Design Focus

MoFRR (Multicast Only Fast Re-Route) - allows fast reroute for multicast traffic on a multicast router (targets <50ms convergence)

Sends PIM joins on two ECMP upstream interfaces towards the source over alternate paths in the network

Thereby receiving 2 copies of the mcast traffic on two different paths

Targets Large customers, owning their own backbone, and

functioning as SP’s within their organization
