Open Transport

Open Transport was the name given by Apple Inc. to its implementation of the Unix-originated System V STREAMS networking stack. Based on code licensed from Mentat's Portable Streams product, Open Transport was built to provide the classic Mac OS with a modern TCP/IP implementation, replacing MacTCP. Apple also added its own implementation of AppleTalk to the stack to support legacy networks.
