1.1 Glossary
This document uses the following terms:
acknowledgment (ACK): A signal passed between communicating processes or computers to signify successful receipt of a transmission as part of a communications protocol.
Coded Packet: A Source Packet or an FEC Packet.
FEC block: An FEC Packet that is added to the data stream after a group of Source Packets have been processed. In case one of the Source Packets in the group is lost, the redundant information that is contained in the FEC Packet can be used for recovery.
FEC Packet: A packet that encapsulates the payload after running an FEC logic.
forward error correction (FEC): A process in which a sender uses redundancy to enable a receiver to recover from packet loss.
Internet Protocol version 4 (IPv4): An Internet protocol that has 32-bit source and destination addresses. IPv4 is the predecessor of IPv6.
Internet Protocol version 6 (IPv6): A revised version of the Internet Protocol (IP) designed to address growth on the Internet. Improvements include a 128-bit IP address size, expanded routing capabilities, and support for authentication and privacy.
maximum transmission unit (MTU): The size, in bytes, of the largest packet that a given layer of a communications protocol can pass onward.
network address translation (NAT): The process of converting between IP addresses used within an intranet, or other private network, and Internet IP addresses.
network byte order: The order in which the bytes of a multiple-byte number are transmitted on a network, most significant byte first (in big-endian storage). This may or may not match the order in which numbers are normally stored in memory for a particular processor.
Remote Desktop Protocol (RDP): A multi-channel protocol that allows a user to connect to a computer running Microsoft Terminal Services (TS). RDP enables the exchange of client and server settings and also enables negotiation of common settings to use for the duration of the connection, so that input, graphics, and other data can be exchanged and processed between client and server.
round-trip time (RTT): The time that it takes a packet to be sent to a remote partner and for that partner's acknowledgment to arrive at the original sender. This is a measurement of latency between partners.
run-length encoding (RLE): A form of data compression in which repeated values are represented by a count and a single instance of the value.
Source Packet: A packet that encapsulates data that was generated by the user.
terminal client: The client that initiated the remote desktop connection.
terminal server: A computer on which terminal services is running.
Transmission Control Protocol (TCP): A protocol used with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. TCP handles keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet.
User Datagram Protocol (UDP): The connectionless protocol within TCP/IP that corresponds to the transport layer in the ISO/OSI reference model.
MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
