An example of the effect of IGMP snooping on the traffic in a LAN. IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic to control delivery of IP multicasts. Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need ...
The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IPv4 networks to establish multicast group memberships. IGMP is an integral part of IP multicast and allows the network to direct multicast transmissions only to hosts that have requested them.
This process of listening to the IGMP traffic is called IGMP snooping. Additionally, some switches with layer 3 capabilities can act as an IGMP querier. In networks where there is no router present to act as a multicast router, a switch with IGMP snooping querier enabled can be used to generate the needed IGMP messages to get users to subscribe ...
FD&C Red No. 40, more commonly known as red 40, is making headlines again as lawmakers debate whether food dyes should remain legal in the United States. The dye, which has been registered with ...
In support of link-local multicasts which do not use IGMP, any IPv4 multicast address that falls within the *.0.0.0 / 24 and *.128.0.0 / 24 ranges will be broadcast to all ports on many Ethernet switches, even if IGMP snooping is enabled, so addresses within these ranges should be avoided on Ethernet networks where the functionality of IGMP ...
"Refrigerated truck transportation is a major pain point in the food supply chain right now. There's a shortage of drivers, long-haul truck rates are up and eggs are of course very transportation ...
