Multicast Switching
A process whereby the switch filters incoming multicast frames for
services for which no attached host has registered, or forwards them to all
ports contained within the designated multicast VLAN group.
Multicast VLAN Registration
A method of using a single network-wide multicast VLAN to transmit
common services, such as such as television channels or video-on-demand,
across a service-provider’s network. MVR simplifies the configuration of
multicast services by using a common VLAN for distribution, while still
preserving security and data isolation for subscribers residing in both the
MVR VLAN and other standard or private VLAN groups.
Multiple Spanning Tree Protocol (MSTP)
MSTP can provide an independent spanning tree for different VLANs. It
simplifies network management, provides for even faster convergence than
RSTP by limiting the size of each region, and prevents VLAN members
from being segmented from the rest of the group.
Network Time Protocol (NTP)
NTP provides the mechanisms to synchronize time across the network.
The time servers operate in a hierarchical-master-slave configuration in
order to synchronize local clocks within the subnet and to national time
standards via wire or radio.
Out-of-Band Management
Management of the network from a station not attached to the network.
Port Authentication
