How to set the communication port parameters to improve the performance of the network - Database & Sql Blog Articles
In a network where stations 2 and 10 are designated as primary stations, the highest address (station 10) is set to 15. For station 2, the address gap refers to the range from 3 to 9, while for station 10, the address gap covers from 11 up to the maximum site address of 15, and also includes stations 0 and 1. Tokens are passed between primary stations in the network, and overall communication is managed through time-sharing. Since all primary stations do not join the token ring simultaneously, a master station that holds the token must periodically check if a new primary station has joined the network with a higher address. This process is known as the refresh factor, which involves checking the high site address after the token has been received a certain number of times. If station 2 is configured with an address gap factor of 3, it will check for any new master station within its address gap when it receives the token for the third time. Increasing this factor can enhance network performance by reducing unnecessary checks, but it may slow down the detection of new master stations. To optimize network efficiency, consider the following settings: 1) Set the highest address as close as possible to the actual maximum site. 2) Arrange all master addresses consecutively so that address gap checks are no longer necessary during token transmission. These adjustments help ensure smoother operation and more efficient management of the network’s primary stations.
