Network Working Group B. Cosell RFC #256 BBN NIC #7697 3 November 1971 Categories: B.1 Updates: None Obsoletes: None IMPSYS Change Notification We will shortly install (or perhaps will have already installed) a new version of the IMP system, Version 2513. The new version incorporates two principal changes: 1. A Host will be prevented from sending any messages into the Network for between 40 seconds and a minute and a quarter after he comes alive (this has been changed from between 30 seconds and a minute). 2. The IMP has been given the ability to test its Host interfaces under control of the NCC. This will help us isolate the trouble when the IMP Host communication path is faulty.
