The maximum segment size (MSS) is the largest amount of data, specified in bytes, that a computer or
communications device can handle in a single, unfragmented piece. For optimum communications, the
number of bytes in the data segment and the header must add up to less than the number of bytes in the
maximum transmission unit (MTU).
4.7 PPTP
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables transfers of data from a remote
client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based networks.
PPTP supports on-demand, multi-protocol, and virtual private networking over public networks, such as the
Internet.
