Reference Information

If multiple streams/applications share host buffers, they will influence each other and one application can cause the other to drop packets. To avoid one application influencing another application, the Host Buffer Allowance should be used. If sharing is done across adapters, some sort of time synchronization is needed or adapters might drift away from each other causing buffering and dropped packets. Time synchronization is configured in ntservice.ini.
