The IPTV provider can deliver content to users in unicast or multicast streaming. In multicast, the provider sends many users a single piece of content. The Internet Group Management Protocol (IGMP) makes multicast streaming easy. It is useful when an IPTV provider needs to deliver the same dat...
If an Eth-Trunk interface uses a non-default hash algorithm, this non-default hash algorithm takes effect preferentially even if a global enhanced load balancing profile is configured at the same time. For unknown unicast packets, only the load balancing mode and hash algorithm in the g...
VLAN address spaces are limited. VPLS is therefore introduced to solve those problems. Instead of running STP, VPLS backbone networks use full-mesh connections and split horizon to eliminate loops. For unicast or multicast frames with unknown destination MAC addresses, VPLS discards, processes the fr...
and term1 and term2 are non-backbone networks running IPv6. The backbone network runs IPv4. To transmit packets between group1 and group2 and between term1 and term2 over the backbone network, use GRE to establish a tunnel between DeviceA and DeviceB. When DeviceA receives a packet from...
to identify unicast traffic to be encrypted. An IPsec policy requires a large number of ACLs to be defined, which is difficult to implement. DSVPN combines NHRP and mGRE with IPsec to provide ease of device configurations, while ensuring data transmission security and facilitating network ...
What's the difference between a unicast and multicast MAC address? A unicast MAC address is used to send data to a specific device on the network, while a multicast MAC address is used to send data to multiple devices at once. How does MAC filtering improve network security?
When Configuration Manager SP1 clients run Windows 7, Windows 8, Windows Server 2008 R2, or Windows Server 2012, you can supplement the Wake on LAN site setting for unicast packets by using the wake-up proxy client settings. This combination helps to wake up computers on subnets without the ...

This wastes network bandwidth and threatens network information security. IGMP Snooping solves this problem. As shown in the above figure, when IGMP snooping is not running on the switch, multicast packets are broadcast to Host A, B, C. But when IGMP snooping is enabled, the IGMP Snooping ...
Currently, most unicast IP routing takes place over IP version 4 (IPv4) internetworks. Windows Server 2003 also supports the next generation of IP, IP version 6 (IPv6). This technical reference describes unicast IPv4 routing on IPv4 internetworks. Frequently, IPv4 internetworks are referred ...
