IGMP snooping and GMRP for ltering multicast
data trafc
Weidmüller managed switches support GMRP (Generic
Multicast Registration Protocol) and IGMP snooping.
These protocols limit multicast data trafc so that it is only
forwarded to the devices that actually require it. This reduces
unnecessary network data trafc.
IEEE 1588 PTP - improves time synchronisation of
automation devices
IEEE 1588 PTP, also known as Precision Time Protocol (PTP),
was developed to synchronise real-time clocks which are
located at specic nodes of a distributed system. Weidmüller
managed switches with IEEE 1588 PTP are particularly
suited for motion control applications where distributed
clocks must be synchronised with high levels of
accuracy.
QoS supports real-time capability
Quality of Service (QoS) enables the possibility of
prioritisation of data trafc in a network and ensures
that important data is consistently available. Weidmüller
managed switches can deal with IEEE 802.1p/1Q layer
2 CoS tags and also layer 3 TOS information. The QoS
functionality of Weidmüller’s managed switches improves
network performance and ensures that time-critical
applications are given priority.
