Definitions for "Retransmission"
Keywords:  unreliable, sip, udp, packet, reply
SIP messages are often transferred by means of unreliable transport protocols such as UDP. SIP implementations would send SIP request again if receives no reply within a period of time to compensate for possible packet losses that can occur in the network.
Retransmission refers to one of the basic mechanisms used by protocols operating over a packet switched computer network to provide reliable communication (such as that provided by a reliable byte stream, for example TCP).
CQG retransmits past market data each evening. The retransmitted data is used to construct the charts on the CQG system. By retransmitting the data, each user is assured of receiving updated and accurate information. CQG retransmits the data in the form of 5-minute, 30-minute, 60-minute, Daily, Weekly, and Monthly bars. The type and quantity of the retransmitted data varies from contract to contract. The more active contracts typically receive the most transmitted data. The Time & Sales data files are relatively large since they contain each trade for each contract on the system. For this reason, the amount of Time & Sales data that is available at any given time may be limited to several days. The duration of the charts that are constructed from Time & Sales data (1-9 Minute Bars) is limited by the amount of Time & Sales data available in the system. For example: With two days of Time & Sales data in the system, a 1-minute chart can display enough bar data to scroll through several screens; whereas a 9-minute chart may display only 1/9th of the number of bars.
