Question | Answer |
---|---|
SLIP | Serial Line Internet Protocol -Original method of transmitting IP packets over serial (e.g. telephone) lines -First widespread usage in 1984 -Standardized by IETF in 1988 in RFC 1055 |
Drawbacks of SLIP | -Cannot provide packet addressing or ID information -Does not support error detection or correction -Does not support compression -Only supports the IP protocol -Limited to slow speeds (<19.2 Kbps) |
PPP | Point-to-Point Protocol -The current methodology for transporting multi-protocol datagrams over point-to-point links -Standardized in RFC 1661 |
Components of PPP | -A methodology for encapsulating multi-protocl datagrams -Link Control Protocol (LCP) for establishing, configuring, and testing the data link -A family of Network Control Protocols (NCP) for establishing and configuring different Network layer protocol |
Advantages of PPP | -Support for compression -Link quality monitoring -Support for security features such as user authentication -Support for error detection and correction -Support for encryption -Support for many different protocol datagrams |
PPTP | Point-to-Point Tunneling Protocol -Secures client connections over the Internet -One of the underlying technologies that VPNs use -Supports multiple protocols (TCP/IP, NetBEUI, IPX) -Packets are encrypted and encapsulated in PPP packets -A session ke |
PPPoE | Point-to-Point Protocol over Ethernet -Derived from PPP protocol -Designed for securing broadband connections to the Internet which use Ethernet instead of a serial connection -Requires user authentication to the PPPoE server -Used frequently by broad |
RDP | Remote Desktop Protocol A Windows graphical remote access protocol -Based on ITU std. T.120 (for multichannel conferencing) -Uses port 3389 by default -Runs at Application Layer |
