Basler Network Drivers and Parameters AW00097603000286 Basler aviator GigEA.2.1 General ParametersEnable Resend - Enables the packet resend mechanisms.If the Enable Resend parameter is set to false, the resend mechanisms are disabled. Theperformance driver will not check for missing packets and will not send resend requests to thecamera.If the Enable Resend parameter is set to true, the resend mechanisms are enabled. Theperformance driver will check for missing packets. Depending on the parameter settings and theresend response, the driver will send one or several resend requests to the camera.Receive Window Size - Sets the size of the receive window.A.2.2 Threshold Resend Mechanism ParametersThe threshold resend request mechanism is illustrated in Figure 65 where the followingassumptions are made: Packets 997, 998, and 999 are missing from the stream of packets. Packet 1002 is missing from the stream of packets.(1) Front end of the receive window. Missing packets are detected here.(2) Stream of packets. Gray indicates that the status was checked as the packet entered thereceive window. White indicates that the status has not yet been checked.(3) Receive window of the performance driver.(4) Threshold for sending resend requests (resend request threshold).(5) A separate resend request is sent for each packets 997, 998, and 999.(6) Threshold for batching resend requests for consecutive missing packets (resend requestbatching threshold). Only one resend request will be sent for the consecutive missingpackets.993 994 995 996 1000 1001 1003 1004 1005 1006 1007992991990989988987986985TimeDIAGRAM IS NOT DRAWN TO SCALEFig. 65: Example of a Receive Window with Resend Request Threshold & Resend Request Batching Threshold(6)(5)(3) (2)(1)(4)
