provides authentication for PPP connections between a Windows-based computer and an

MTU
The Maximum Transmission Unit is the largest physical packet size, measured in bytes, that
a network can transmit. Any messages larger than the MTU are fragmented into smaller
packets before being sent.
Multicast
A Multicast sends the same message to a select group of recipients. Sending an e-mail
message to a mailing list is an example of multicasting. In wireless networks, multicast
usually refers to an interaction in which the access point sends data traffic in the form of
IEEE 802.1x Frame s to a specified set of client stations ( MAC addresses) on the network.
Some wireless security modes distinguish between how unicast, multicast, and broadcast
