Hardware requirements
Switches
The following minimal requirements apply to switches:
–
1 Gbit or higher with hardware switching capabilities.
–
Quality of Service through differentiated services with 4 or more output queues and strict
priority packet scheduling.
–
(Optional) IGMPv3 or IGMPv2 snooping. To optimize bandwidth usage, IGMP snooping
can be used. This is useful in systems with >10 multicast channels, although not
absolutely required. Sufficient performance for handling a large number of IGMP query
responses, depending on the number of (directly or indirectly) connected devices to that
switch. Hardware support for IGMP is strongly recommended.
–
(Optional) (Rapid) Spanning Tree support in case redundant networks are used.
–
(Optional) SNMPv3 support for switch supervision purposes.
The following table shows recommended switches to use with OMNEO. These managed
switches may offer support for the optional requirements as stated above.

The price range for these switches varies depending on the number of ports the switch may
have. More expensive switches are also available, but have not been taken into consideration.
