From
the architecture point of view, does the product
allow for any interface/integration with any other
system? Or is designed to be a stand-alone
application? |
|
Spreed is designed as an integrated
application. Spreed can be easily embedded within web
pages and other systems. spreed has a extremely powerful
remote control interface (
Spreed Remote Control
). |
 |
Does
the vendor provide any SDK or API to enable
integration with other applications (like LMS, for
example)? |
|
SDK available. Web service integration
available. XML-RPC interface. |
 |
Does
the vendor provide any integration services? If
yes, are there any known case studies/success
stories of integration? |
|
Yes. Spreed has been successfully
integrated into existing portals by social networks,
e-learning companies, telecommunication companies and
Internet Service Provider (ISPs). |
 |
Is
there any SIP support for AV communications?
|
|
Yes. SIP and IAX2 (Asterisk). |
 |
Is
there any integration possible with a 3rd party
scheduling/calendaring system to enable
automatic/rapid creation/scheduling of sessions?
|
|
Yes. MS Outlook and Zarafa and other
integrations are still available. |
 |
Is
there any integration available with MS
Exchange/Outlook? |
|
Yes. Spreed Meetings can be created and
scheduled directly from within Outlook (with a plugin
available from zarafa.com). Spreed Web Meetings are
created like a normal meeting scheduled with Outlook
calendaring. By double-clicking on the meeting entry the
Spreed meeting room is entered. |

What
are the recommended server specifications?
|
|
The Spreed web conferencing server is available as
Virtuozzo virtual appliance, as software installation
and as server appliances. Spreed server virtual
appliances take use of the following
configurations:
Software environment:
- SWsoft Virtuozzo, 1VE
- Operating systems:
-
- CentOS 3.x, 4.x
- Red Hat Fedora Core 1, 2, 4
- Red Hat 9 Red Hat Enterprise 3, 4
- SuSE Enterprise Server 9
Hardware:
- 2 or 4 CPU, 64-Bit, 2+ GHz Intel Core2Duo/XEON or
AMD Opteron
- 4/8/16 GB RAM depending on usage
- IP bandwidth from 10 MBit/s up to 4 GBit/s per
server (depending on usage)
- 200 GB HD (RAID-5)
- Optional: IPSec/SSL/TLS protocol accelerator
(PCI-X adaptor)
|
 |
Is
there any support for NLB or clustering or
distributed server architecture? |
|
Yes. Spreed servers are built to be load
balanced and cascaded with Spreed streaming
concentrators. |
 |
Is
there any support for Multicast? |
|
Yes, Spreed servers communicate with
Spreed servers using a Reliable Datagram Protocol (SRDP -
Spreed reliable datagram protocol). The SRDP
server-to-server communication protocol can be a
multicast protocol and/or peer-to-peer. The number of
Spreed servers and streaming concentrators on a network
(Spreed peers) is virtually unlimited. |
 |
Is
there any support for distribution of CDNs?
|
|
Yes. |
 |
Is
there any server redundancy support? |
|
Yes, hot fail-over is optionally
available. When a Spreed server fails or a network
connection is interrupted, other Spreed servers will take
over the running session within few seconds. With hot
fail-over running sessions will be interrupted less then
a few seconds in case of fail-over. |
 |
From
the design point of view, what does the return path
from the trainee to the trainer look like? How does
it work? |
|
Technically spoken, Spreed is not
client-side peer-to-peer. Trainers and trainees do not
communicate directly to each other through the network.
All network communication is routed through the Spreed
server. However, multiple Spreed servers are
communicating peer-to-peer using its proprietary
high-efficient SRDP (Spreed Reliable Datagram
Protocol). |
