Step 1 |
Cisco Hosted Collaboration Solution supports dedicated deployment of Video Conferencing on a per tenant basis using TMS, Conductor, and Telepresence Servers
(virtual and Physical). Determine whether you intend to offer dedicated TP services along with Centralized TP services using
CTX.
|
Step 2 |
Plan the
capacity requirements for dedicated and shared deployment.
|
Step 3 |
Determine the
inter-enterprise and intra-enterprise networking requirements for video
dialing.
- Determine if you want to
allow video calls between enterprises. To allow outside video calls, set up
your video network and set up the SBCs to allow users to place calls outside of
the enterprise.
- Decide if you want to do
the inter-enterprise routing within the SBC or in the service provider's
softswitch.
- Consider policies on
selectively enabling inter-enterprise video dialing.
- Investigate and understand
the limitations of Lawful Intercept (LI) for inter-enterprise video dialing and
the LI exemption for video dialing.
|
Step 4 |
Determine if
you will use scheduled conferencing or virtual meeting rooms.
Cisco offers
virtual meeting rooms only for Cisco HCS. Scheduled meetings with Cisco HCS are
done through a third-party portal. This portal is supported, but is not
validated.
Scheduled
Conferencing, Rendezvous Conferencing, and Adhoc Video Conferencing are
supported when there are dedicated deployments of Conductor, TMS, and
TelePresence servers. For CTX-based Video deployment, Scheduled Video
Conferencing is not natively supported in HCS. However, with the use of a
third-party portal with CTX, Scheduled Conferencing can be supported.
If you are
planning for a third-party portal, evaluate the third-party portal and validate
it against your requirements.
|
Step 5 |
Determine your
port capacity for video conferencing based on the following estimations. These
estimates provide you with an estimate of the number of users that are expected
to take part in a video conference at any time. Base these considerations on
whether a centralized or dedicated video conferencing solution is being
planned.
- Number of customers using
video conferencing.
- Number of video endpoints
each customer will use.
- Number of simultaneous
video conferences that you expect.
- The average number of
participants in each video conference.
- Average duration of video
conference.
Use the
following calculation to determine the port capacity.
- Number of ports needed.
This is the (number of video-enabled customers) x (number of simultaneous video
meetings per customer) x (number of participants per meeting) x (average number
of ports per participant).
- For example: (10
customers) x (2 simultaneous meetings per customer) x (6 participants per
meeting) x (1 port per participant) = 120 ports.
The average
number of ports per participant must take into account the distribution of
different types of endpoints (number of screens), the quality of the video (HD,
SD, Audio only), and presentation sharing. Each port is assumed to provide a
1080p HD quality video.
|
Step 6 |
Determine
the type of video endpoints supported in the network.
- Immersive video
endpoints.
- Nonimmersive video
endpoints.
Immersive
video endpoints enable the best possible in-person TelePresence video
collaboration experience, where attendees across multiple locations feel as
though they are in the same room. Due to the high quality of the video media,
immersive video endpoints consume higher amounts of bandwidth and network
resources than nonimmersive video endpoints.
|
Step 7 |
Determine
whether to provide video dialing between different service providers.
- To provide video dialing
between different service providers, set up the SBC to provide connectivity
between the different service providers.
- Make sure that agreements
and routing policies are in place for interprovider video dialing.
|
Step 8 |
Determine
whether you want to support over-the-top (OTT) connectivity for guest clients
from other enterprises and integrate Microsoft Lync along with Dedicated Video
Conferencing with Conductor/TMS/Virtual TS.
You can use
Cisco Expressway to set up connectivity.
|
Step 9 |
Determine if
you need to transcode codecs within your video network.
- If yes, you need to
implement the Cisco TelePresence MSE 8710 server for transcoding.
- If no, you can use
Multipoint Switch (CTMS). CTMS is a less expensive option than the MSE, but
DTLS is not supported with CTMS. Any CTX-based calls are unsecure if you choose
CTMS.
|
Step 10 |
Determine
your bandwidth and QoS requirements for video, using the following information:
- Number of ports
- Number of endpoints
- Immersive or nonimmersive
video.
Note
|
Immersive video has higher bandwidth requirements.
|
- Types of endpoints.
Use the
following guidelines to evaluate bandwidth requirements:
- For every (shared)
three-screen TelePresence room at 1080p, add 16.7 Mbps (assumes 100-percent
utilization because these are shared services).
- For every single-screen
TelePresence at 1080p, add 4.5 Mbps (assumes 100-percent utilization).
- For every single-screen
TelePresence at 720p, add 1.68 Mbps (assumes 100-percent utilization).
- For shared EX90 at 720p,
add 1.5 Mbps (assumes 100-percent utilization).
- For personal (nonshared)
EX90 at 720p, add 136 Kbps (assumes much lower utilization).
|
Step 11 |
Determine your
security requirements for signaling and media.
- TLS for signaling
encryption.
- DTLS for media encryption.
- SRTP media encryption.
|
Step 12 |
Determine the
CTX model to use.
- Starter Package—If you
choose the Starter Package, there is a maximum of 250 ports with no active
meeting management license. Active video calls are not preserved. ACE is not
required with the Starter Package.
- Classic Package—If you
choose the Classic Package, ACE is implemented.
|
Step 13 |
Consider the
following when determining networking requirements:
- Data Center Network for
video infrastructure.
- VLANs.
- Virtual routing and
forwarding (VRF).
- TPaas network devices and
applications which are deployed in a shared environment.
