TTE exchange system and method supporting time slice moving and application

Abstract

The invention belongs to the technical field of communication, and discloses a TTE switching system and method supporting time slice moving and application, the TTE switching system supporting time slice moving comprises a signaling processing module, an input dispatch table module, an input processing module, a cache region module, a Crossbar switching network module, an output dispatch table module and an output processing module; the TTE exchange method supporting time slice migration comprises the following steps: establishing a hard path; receiving and caching a data frame; executing police management operation; outputting scheduling information query; port forwarding and time slice moving being carried out; and outputting the processing operation. According to the invention, on the basis of the time-triggered Ethernet, time slice moving can be realized; an end-to-end hard path is established through signaling, the method can be applied to a large-scale deterministic Ethernet switched network, the problem that the prior art cannot support TT service time slice migration is solved, the TT service conflict condition is processed, and technical support is provided for large-scale application and expansion of the deterministic network.

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 implemented 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 tra...
