Data distribution service timing and buffering management for Ethernet

QoS management for performance analysis of switched Ethernet networks

“…Queuing in the Ethernet's switch and router's buffer is affected by the packet's size as it travels between nodes. This affects the rate at which packets are received and sent, and hence the pace at which they are processed [7]. When packets become too large for the maximum transmission unit (MTU), they cause delays in the transmission from beginning to finish [7].…”

“…This affects the rate at which packets are received and sent, and hence the pace at which they are processed [7]. When packets become too large for the maximum transmission unit (MTU), they cause delays in the transmission from beginning to finish [7]. Segmentation slows down the data transfer rate and lowers the network's quality of service.…”

“…The systems installed in factories are linked to the corporate network and software. Using a multi-tiered architecture [7] is one technique to connect the automation systems on the manufacturing floor with the corporate information systems. Business logic is abstracted away from presentation logic and data storage, a technique borrowed from database systems' multi-tier design.…”

“…Business logic is abstracted away from presentation logic and data storage, a technique borrowed from database systems' multi-tier design. The data layer is replaced by a controller network in the multi-tier architecture described in [7]. As long as functionality is kept separate, this improves availability and security.…”

“…In the first category, superior Ethernet switches are used. Among them are TTEthernet [7] [8] and PROFINET IRT [9], both of which were designed with time-triggered operations in mind. Overlay protocols, which govern the traffic sent to COTS switches, have also been the subject of much study and subsequent commercialization as a second class of RTE protocols.…”
