Abstract​

RFC 57 comments on NWG/RFC #54, the first official protocol proffering, and records ideas that were deliberately left out of it. It proposes to distinguish real errors, which only a broken NCP can generate, from overflow conditions caused by exhausted system resources, and to extend the ERR message with an 8-bit field designating one of nine error types, from UNSPECIFIED ERROR to ILLEGAL SOCKET SPECIFICATION - DATA. A new OVF control command is proposed so that an overflow is reported explicitly instead of masquerading as a refused connection. The memo also proposes the RESET (RST) and RESET REPLY (RSR) commands, which let hosts re-initialize cleanly after a hard crash.
