Work in Progress: Configuration of Cycle Duration in Cyclic Queuing and Forwarding

Abstract

TO PROVIDE a standard real-time data network, the IEEE Time-Sensitive Networking (TSN) working group has defined several extensions to Ethernet. Among them, Cyclic Queuing and Forwarding (CQF), inspired by the "stop-and-go" queuing discipline [1] , has been introduced to provide bounded delay and limited jitter [2] . Briefly (see Section II ), CQF assumes a common time cycle T and uses two queues per output port to alternately store and forward packets. It guarantees that the delay experienced by a packet traversing h nodes lies between ( h −1) T and ( h +1) T .

Packet switching

In telecommunications, packet switching is a method of grouping data into packets that are transmitted over a digital network. Packets are made of a header and a payload. Data in the header is used by networking hardware to direct the packet to its destination, where the payload is extracted and used by an operating system, application software, or higher layer protocols. Packet switching is the primary basis for data communications in computer networks worldwide.

Network scheduler

A network scheduler, also called packet scheduler, queueing discipline (qdisc) or queueing algorithm, is an arbiter on a node in a packet switching communication network. It manages the sequence of network packets in the transmit and receive queues of the protocol stack and network interface controller. There are several network schedulers available for the different operating systems, that implement many of the existing network scheduling algorithms. The network scheduler logic decides which network packet to forward next.

Packet loss

Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, or network congestion. Packet loss is measured as a percentage of packets lost with respect to packets sent. The Transmission Control Protocol (TCP) detects packet loss and performs retransmissions to ensure reliable messaging.
