Delay Guaranteed Window Bandwidth Allocation Policy for Industrial Ethernet Switch

To resolve the problem that switched industrial Ethernet can´t provide delay guaranteed service, a window bandwidth allocation policy based on deterministic network calculus model is presented. The policy introduces the principle of window flow control into industrial Ethernet switch and relative service curve model is got, through which combined with the arrival curve model of the input data flow, the bandwidth and credits are allocated to guarantee the different delay required. The example results prove that the policy can provide delay guaranteed transmission service for the hard industrial data
