Formally, it is a channel (often bidirectional, but sometimes unidirectional) down which one entity can send a sequence of bytes to the entity on the other end. In almost all instances, the channel has the property that it is reliable; i.e. the exact same bytes emerge, in the exact same order, at the other end.
Less formally, one can think of it as a pipe between the two entities; one entity can insert bytes into the pipe, and the other entity then receives them.
A bytestream is an abstraction used in computer science to describe a particular kind of communication channel between two entities.
Formally, it is a channel (often bidirectional, but sometimes unidirectional) down which one entity can send a sequence of bytes to the entity on the other end.
One well-known example of a communication protocol which provides a byte-stream service to its clients is the Transmission Control Protocol of the Internet protocol suite, which provides a bidirectional 8- bitbytestream; it is being used to bring you this Web page.
BYTESTREAM WITH MARK ON CHAOSNET A mark is recognized on Chaosnet by a packet bearing the opcode 201 (octal).
The basic design of ByteStream with Mark on TCP (and other transport layers that do not implement packets natively) is to preserve record integrity by putting clearly demarcated, byte-counted records in the natural records of the encapsulated stream.
Nevertheless, the ByteStream with Mark must extract the count of the full ByteStream with Mark record from the first such buffer of each ByteStream with Mark record, and maintain and update this count as succeeding component buffers are read.
