- Update from version 2.0.13 to 2.0.14a
- No change in rootfiles
- Release notes for change:-
o scaling improvements for -P, i.e. improved support for large numbers of traffic threads
o major code refactoring (see doc/DESIGN_NOTES) for maintainability, extensibilty, performance, scaling, memory usage
o support for full duplex traffic using --full-duplex
o support for reverse traffic using --reverse
o support for role-reversal character of asterisk in the transfer id
o transfer id now an incrementing integer and no longer the socket id
o support for TCP connect only tests with --connect-only
o isochronous support compiled in by default, must use config to disable
o support --isochronous for both UDP or TCP traffic to simulate video streams
o use of clock_nanosleep when supported to schedule isochronous burst starts, otherwise use nanosleep delay
o support for --trip-times indicating the client and server clocks are synchronized to an accuracy sufficient, note: consider the use of precision time protocol as well as ask your data center to provide access to a GPS disciplined reference time source
o support for --trip-times with -d and -r bidirectional tests
o output TCP connect times (3WHS) in connect reports
o support for application level tcp connect retries via --connect-retries n
o rate-limited options of -b and --fq-rate supported for unidirectional, full duplex and reverse traffic
o reporter thread designed to automatically cause packet reports to aggregate - mitigating and hopefully removing thread thrashing
o support for frame or burst based reporting or sampling vs time based via -i [f|F] (experimental)
o support for UDP traffic only from client to server with --no-udp-fin
o support for write to read latencies (UDP and TCP) with --trip-times
o support for sum only outputs with --sum-only
o support for little's law calculations in --trip-time outputs
o support for --txstart-time <epoch-time> to schedule client traffic start, timestamp support microseconds, e.g. unix $(expr $(date +%s) + 1).$(date +%N)
o support for --txdelay-time to insert delay between TCP three way handshake (3WHS) and data transfer
o support for --no-connect-sync which disables transmit traffic start synchronization when -P is used, defaults to synchronized
o option of --full-duplex implementation uses a barrier on the client side to synchronize full duplex traffic
o no limits to group sum reports, i.e. all clients will get its own sum report per a server
o improved report timestamps, e.g. end to end or client and server based timestamps with --trip-times
o improved settings messaging
o improved messaging for --tcp-congestion or -Z
o re-implemented -U for single UDP server with minimal threading interactions
o re-implemented -1 or --singleclient where server will serialize traffic runs
o warning message if the test were likely CPU bound instead of network i/o bound
o fix the case when -P <value> is set on the server such that summing output is displayed
o multicast listener will autoset -U (single server), e.g -P > 1 not supported for multicast
o multicast listener no longer busy drops multicast packets during traffic test, i.e. only server thread receives them
o immediate bail out on mutually exclusive command line options
o fix -o or --output using freopen to redirect stdout and stderr to a file
o man page updates with examples
o tested with 1000's of traffic streams, WiFi, 10G and 100G

Not sure why this has ever been there. This simply makes it
nicer to read and edit because we can have line-breaks now.

Just some housekeeping... :-)
