DESCRIPTION | SWP means Sliding Window Protocol. SWP is a bit slower than 3BSCP, faster than SCP & 1SCP and more likely to succeed than 3BSCP. will be transmitted. While the 3BSCP protocol must resend an entire block when it gets an error, this protocol sends only the line that was not acknowledged. It is therefore faster under non-ideal circumstances than 3BSCP. the Longitudinal parity check checksum used by the 3BSCP protocol and is comparable in speed to the 3BSCP protocol, but is a bit slower and more likely to succeed. Speed reported is actual characters sent successfully. Characters (lines) resent because of errors are not included in the total as they are iun the 3BSCP protocol. Error recovery is much better. During transmission of the text of the messasge, both sender and receiver stay in basically one program and do not cause as much swapping therefore. Short of loss of the virtual connection, messages sent with this protocol |
