IGMP snooping and GMRP for ltering multicast
data trafc
Weidmüller managed switches support GMRP (Generic
Multicast Registration Protocol) and IGMP snooping.
These protocols limit multicast data trafc so that it is only
forwarded to the devices that actually require it. This reduces
unnecessary network data trafc.
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 specic 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 trafc 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.
