Note 54
From RFC 672 by Rick Schantz, December 1974:
When a user initially requests service from a TIP, the TIP will perform a broadcast ICP [Initial Connection Procedure] to find an available RSEXEC which maintains an authentication data base. The user must then complete a login sequence in order to authenticate himself. If he is successful the RSEXEC will transmit his unique ID code to the TIP. Failure will cause the RSEXEC to close the connection and the TIP to hang up on the user. After the user is authenticated, the TIP will accumulate accounting data for the user session. The data includes a count of messages sent on behalf of the user, and the connect time for the
user. From time to time the TIP will transmit intermediate accounting data to Accounting Server (ACTSER) processes scattered throughout the network. These accounting servers will maintain files containing intermediate raw accounting data. The raw accounting data will periodically be collected and sorted to produce an accounting data base. Providing a number of accounting servers reduces the possibility of being unable to find a repository for the intermediate data, which otherwise would be lost due to buffering limitations in the TIPs. The multitude of accounting servers can also serve to reduce the load on the individual hosts providing this facility.
