FLEXAMINER: RECOMMENDATIONS

Time synchronization

FlexAminer and client must be time synhronized

NTP server configuration

Open a telnet/ssh session on FlexAminer (login: admin)

Go to network menu and then to ntp sub menu

Set the ntp1 server

Quit the sub-menu and valid modification

Set time

If there does not exist any NTP server, set UTC time on FlexAminer

read current date & time : utc_date

set new date & time (UTC) : utc_sdate



FLEXAMINER: RECOMMENDATIONS

Network configuration

Flextream Out Of Band case

The IGMP Querier address of the switch connected to Eth1 (NIC2) is in the same network

than Eth1 (IP@/ Netmask)

Flextream In Band case

The IGMP Querier address of the switch connected to Eth0 (resp. Eth2) is in the same

network than Eth0 (resp. Eth2) (IP@/ Netmask)

Eth0 (NIC1) and Eth2 (NIC3) are connected to 2 different IP switches with different IGMP

Querier addresses

Eth0 and Eth2 are not in the same network

Read IGMP Querier IP address

Use ssh/telnet session as admin user

Example with eth1

15

Igmp query network = 198.18.128.1

SETTINGS: AUTO FLEXTREAM CONFIG. DISCOVERING MODE

17

Mode description

FlexAminer gets Flextream configuration from Networks elements:

Full automatic Flextream configuration discovering mode

FlexAminer gets automatically Flextream configuration after reading configuration from

netProcessor and from encoders

Partial automatic Flextream configuration discovering mode (default mode)

FlexAminer gets automatically Flextream configuration after reading configuration from

netProcessor only

Some encoders parameters can not be learnt (VBR quality, Tant, service name)

User has to rename service names in {Network view} in FlexAminer Web interface

Compatibility

Full automatic Flextream configuration discovering mode can be used all

the time excepted in following cases:

EM4000 version < 2.6



18

How to set the mode

Open a telnet/ssh session on FlexAminer (login: admin)

Go to maintenance menu and config sub menu

Read current mode

Set the mode and reboot



19

Partial automatic Flextream configuration discovering mode

Rename service in {network view} in FlexAminer Web interface

(POOL & SERVICE)

Pool analysis

Linear style:

This view allows a comparison between all services in a pool dealing with

Evolution of allocated or requested bitrates

Stacked style:

This view allows user to estimate

the possibility to add a new service in case of VBR pool (metric = allocated bitrate)

The total pool bitrate to set in MXS (metric = requested bitrate)

A filter on the services list can be set by user.

Service analysis

Linear style:

This view allows a comparison of the evolution of the requested bitrate vs

allocated bitrate



FLEXAMINER: DASHBOARD: SYNTHESIS (POOL)



FLEXAMINER: DASHBOARD: SYNTHESIS (POOL)

Pool analysis

This view offers a comparison between all services in a pool according

their Flextream quality on a time slot:

Static metrics

Min & Max bitrate set on MXS

Dynamic metrics

Allocated bitrate average

Requested bitrate average

Range of allocated bitrates

Range of requested bitrates

A filter on the services list can be set by user.



FLEXAMINER: DASHBOARD: RATIO TIMELINE

Ratio allocated bitrate / requested bitrate

allocated bitrate > requested bitrate

allocated bitrate < requested bitrate


FLEXAMINER: DASHBOARD: RATIO TIMELINE

(POOL & SERVICE)

Pool & service analysis

This view allows user to know for a pool or a service

The evolution of the ratio allocated bitrate/requested bitrate

Time intervals where more or less complexity is required



FLEXAMINER: DASHBOARD: ALLOCATION DISTRIBUTION PIE

(POOL & SERVICE)

36

Ratio allocated bitrate / requested bitrate

Upper: Allocated bitrate > requested bitrate + 10 % Lower: Allocated bitrate < requested bitrate - 10 % Close : requested bitrate - 10 % < Allocated bitrate < requested bitrate + 10%



(POOL & SERVICE)

Pool & service analysis

This view allows user to know for the pool or a service

How many times allocated bitrate = requested bitrate +/– n%

How many times allocated bitrate < requested bitrate – n %

How many times allocated bitrate > requested bitrate + n %

The percentage « n %» can be set by user among global settings



FLEXAMINER: DASHBOARD: BITRATE DISTRIBUTION PIE

(SERVICE)

38

Close to Max: bitrate > max bitrate - 10 % Close to min: bitrate < min bitrate + 10% Normal : min bitrate + 10 % < bitrate < max bitrate - 10%



(SERVICE)

Service analysis

This view allows user to know for the service

How many times video bitrate is closed to MAX video bitrate set in MXS

bitrate >= MAX bitrate – n%

It could be interesting to set n% to know how many times bitrate >= specific bitrate

(=MAX- n%)

How many times video bitrate is closed to MIN video bitrate set in MXS

bitrate <= MIN bitrate + n%

How many times video bitrate is far from MAX & MIN video bitrates set in MXS

MIN bitrate + n% < bitrate < MAX bitrate – n%

The metric can be allocated bitrate

or requested bitrate

The percentage « n %» can be set

by user among global settings
