5 results about "Type of service" patented technology

The type of service (ToS) field is the second byte of the IPv4 header. It has had various purposes over the years, and has been defined in different ways by five RFCs. Prior to the redefinition, the ToS field could specify a datagram's priority and request a route for low-delay, high-throughput, or highly-reliable service. Based on these ToS values, a packet would be placed in a prioritized outgoing queue, or take a route with appropriate latency, throughput, or reliability. In practice, the ToS field never saw widespread use outside of US Department of Defense networks. However, a great deal of experimental, research, and deployment work has focused on how to make use of these eight bits, resulting in the current DS field definition.

Data transmission method and device

The present application discloses a data transmission method and device and relates to the technical field of communication to improve the multiplexing flexibility of a HARQ unit. The method includesthat a terminal device receives the configuration information sent by a network-side device, wherein the configuration information includes the information of a first hybrid automatic repeat request (HARQ) unit, the information of the first HARQ unit is configured to instruct the data of N types of services of the terminal device controlled by the first HARQ unit to be transmitted on a wireless resource having at least two physical characteristics, N is an integer greater than or equal to 1, and the first HARQ unit is a HARQ entity and / or a HARQ process; and the terminal device transmits the data of the N types of services according to the configuration information.
