Why Monitor Media Services?

Media Monitoring Tools

– Performance Monitor Analyzing user traffic

– Mediatrace Enhanced Path Tracing

– IPSLA VO Generating Synthetic Application Traffic

– Media Services Interface (MSI) Getting the Endpoint Perspective

MSI Details

Why Monitor Video Services?

Video service delivery validation & troubleshooting

End users associate poor video quality with poor network service

– Validation via monitoring will lead to earlier identification of issues and greater confidence in network

– Video is sensitive: early detection of network issues that may affect all traffic

Network may not be the problem!

– PC/mobile device based applications

Contractual SLAs need to be validated

– Violations may incur punitive costs

Per-Application Latency, Jitter, Loss Targets

General Guidelines

Application Latency Jitter Loss (VoD) Loss (Live)

Streaming Video < 1000 ms < 100 ms < 0.1% < 0.05%

Video Conferencing < 150 ms < 30 ms NA < 0.10%

Performance Monitor


Dedicated Protocol Analyzers

Wireshark and other protocol analyzers are great – Detailed analysis for variety of protocols at deep level

Dedicated probes are expensive to deploy pervasively – Operator has to make difficult judgment calls on where the problem is going to be– before it

happens

Can be challenging after the fact- need on-site trained personnel.

12


Embedded Packet Capture & Analyze

Capture packets locally to buffer on router

Store to flash, USB, FTP, TFTP for analysis in protocol analyzer – IOS XE Cat 4k Sup 7E & Sup 7L-E (XE 3.3.0 SG) include built in Wireshark decode

capability

Capture does not add traffic to network

Performance Monitor

Network nodes are able to discover & validate RTP, TCP and IP-CBR traffic on hop by hop basis

À la carte metric (loss, latency, jitter etc.) selections, applied on operator selected sets of traffic

Allows for fault isolation and network span validation

Cross-network synchronized time windows for measurement

– same 30 second (default) intervals measured

Per-application threshold and altering.

Triggered Packet Capture of Impaired Voice

1. Performance Monitor analyzes traffic traversing router/switch.

2. On threshold being crossed, Embedded Packet Capture feature saves 60 seconds of that traffic and emailed to a server.

3. Operations can perform post-analysis.

2. Capture of impaired

traffic emailed for analysis

1. Performance monitor

analyzes traffic, looking for

Mediatrace

26


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

Let mediatrace do the walking for you!

MSI Management

MSI provides a REST-based API to manage endpoints that support MSI – http(s)://<IP>/msi/

Using this API, an authorized management station can: – query for device, user, flow metadata monitor performance

– Initiate mediatraces & results

– Subscribe to event and notifications

– Manage thresholds

41


MSI Management – What can you do? (1)

Query for flow related information:

– Get a list of all flows on the endpoint (e.g. WebEx data, WebEx Audio etc.)

– Get details (e.g. IP, port numbers, protocol) related to a flow

– Get the minimum monitoring interval on a flow

Performance Monitor

– Get a list of active monitors

– Get details (index, descriptor etc.) on a specific monitor

– Get list of available reports on a monitor

– Get a report for a monitor

– Create / delete a monitor

42


MSI Management – What can you do? (2)

Mediatrace

– Get a list of active mediatrace sessions

– Get details on a specific mediatrace session with links to status and reports

– Get configuration (monitoring interval, timeout etc.) related to a mediatrace

– Get a report for a mediatrace

– Get status of a mediatrace

– Initiate / delete a mediatrace

Enhanced Manageability

– DNS based service discovery

– Initial presence notifications

– Thresholding

– Notifications

– Metadata

– Reverse Mediatrace

Designed to Work Together

Media Monitoring technologies work independently

But:

– IPSLA VO traffic is of type RTP, so can be analyzed by perf-mon

– perf-mon can be enabled by mediatrace to analyze RTP traffic

– mediatrace can perform fault-isolation on IPSLA VO traffic

– * Cisco Prime Collaboration Manager can run and visualize mediatrace on IPSLA VO traffic

A Phased Approach to Monitoring For Cisco UC/ VC Applications

Situation:

– Intermittent issues with voice/video quality. Operator wants to quickly discover and resolve issues to provide a stable SLA service.

1. Deploy Collaboration Manger to monitor phone and VC endpoints, ‘over the top’ No network changes needed.

MSI MSI

Collab Manager

1. Deploy Collab

Manager to monitor

sessions and endpoints

globally

A Phased Approach to Monitoring

2. Via CP Top 10 Reports, identify worst performing endpoints and sites.

MSI MSI

Collab Manager

2. Identify problem sites

via Top 10 reports

A Phased Approach to Monitoring

3. On identified problem sites, enable performance monitor & mediatrace.

4. Localize problem using Collab Manager and Mediatrace

MSI MSI

Collab Manager

3. Deploy performance monitor and mediatrace (config) mediatrace responder

4. Perform fault-isolation

using mediatrace.

If network write access

unavl for collab

manager, deploy for

endpoint driven

mediatrace.

Depending on who

controls the LAN / WAN.

May need to deploy on

switches vs. WAN

routers.
