A kind of tte exchange system, method and application supporting time slice transfer

Abstract

The invention belongs to the technical field of communication, and discloses a TTE switching system, method and application supporting time slice migration. The TTE switching system supporting time slice migration comprises: a signaling processing module, an input schedule module, and an input processing module, A buffer area module, a Crossbar switching network module, an output scheduling table module, and an output processing module; the TTE switching method supporting time slice movement includes: establishing a hard path; receiving and buffering data frames; performing police management operations; outputting scheduling information query; Port forwarding and time slice shifting; output processing operations. On the basis of time-triggered Ethernet, the invention can realize time slice transfer; establish an end-to-end hard path through signaling, can be applied to large-scale deterministic Ethernet switching networks, and overcome the inability of the prior art to support TT service time slices It solves the problem of moving, handles the conflict of TT services, and provides technical support for the large-scale application and expansion of deterministic networks.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a TTE switching system, method and application supporting time slice migration. Background technique [0002] At present, with the continuous development of Ethernet technology, the scale of the network and the amount of data in the network are increasing, and the requirements of the equipment in the industrial field for the real-time and reliability of the network are also greatly improved. However, since the traditional Ethernet adopts the packet switching and forwarding realized by statistical time division multiplexing, even if the network transmission bandwidth resources are reserved using the connection-oriented virtual circuit technology, the output port conflict caused by the switching node cannot be avoided. Uncertain queuing delay and delay jitter. Time-Triggered Ethernet (Time-TriggeredEthernet, usually abbreviated as TTE) can provide reliable transm...
