keep a proper transmit event record in the flow layer
so we can accurately distinguish between data and ack packets
after they are sent, for better congestion control and such.

without introducing a vulnerability.

renamed awkward foundPeerEndpoint() to simpler connectAt().

Flow control and borrowing kinda sorta works now, when the moon is full;
will have to rework retransmit mechanism a bit to make it work reliably.

Revision 2768 - Directory Listing

Substantially simplified flow control based on "bytes in flight" count.

Revision 2749 - Directory Listing
Modified Thu Aug 16 17:02:13 2007 UTC (2 years, 3 months ago) by baford

After realizing that all packets were getting queued on the transmit queue
sorted in BSN order - including datagram packets having no valid BSN -
I separated the transmit queues for segments and datagrams.
I'm not sure I'm entirely happy with this solution though.

Major overhaul of stream IDs and attachment mechanism,
to correspond with the current version of the SST paper.
got stream detachment and migration working in the process
(streams automatically migate to new channels as necessary,
e.g., when a host's underlying IP address changes).

Revision 1815 - Directory Listing
Modified Wed Mar 28 13:17:26 2007 UTC (2 years, 7 months ago) by baford
Original Path: trunk/sst/lib/strm

Added a protocol name to the top-level service connectTo()/listen() API,
so that a registered StreamServer is indexed by a (service,protocol) pair.
This design makes it natural to allow a host to support multiple protocols,
or incompatible protocol versions, that provide the same logical service,
and eventually should allow users/administrators to browse and enable/disable
complete logical services without necessarily having to know the details of
which specific protocols are used to provide those services.

The top-level stream API is now, I believe,
pretty close to the way I want it and thus
hopefully approaching some level of stability.

Revision 1811 - Directory Listing

Original Path: trunk/sst/lib/strm

Ephemeral streams now work properly in the cases of:
- small datagrams that fit in one packet
- datagrams up to 64KB that get sent as substreams.

Fragmentation and reassembly of intermediate-size datagrams
is not implemented yet,
and extremely large datagrams don't work because of
outstanding issues in the stream init/attach state machine.

Revision 1800 - Directory Listing

Original Path: trunk/sst/lib/strm

Separated Stream class into two classes:
one representing the object seen in the "public" API,
the other holding the internal state.
The internal BaseStream object can now stay around
after the client has deleted the public Stream,
in order to shut down the stream gracefully in the background.
