reply to in the very first return flight. A more appropriate name

for what we support on the client site is "session resumption," which

is standard TLS terminology. Later, when we add support for 0-RTT

(early data), we can use the 0-RTT terminology again, this time in

proper context.

ignore_init() makes an assumption that the send controller has access

outgoing packets that were batched.

|
|
|
standalone ACK packets.
|
|
|
|
- [OPTIMIZATION] Allow placing more than one STREAM frame from the same
|
|
|
|
stream into an outgoing packet. This change minimizes the number of
|
|
|
|
buffered packets required to store several small HTTP messages by
|
|
|
|
virtue of allowing more than one STREAM frame from HEADERS stream in
|
|
|
|
the same packet.
|
|
|
|
- [OPTIMIZATION] Flush headers when writing to buffered packets. This
|
|
|
|
causes the headers to be written to the same buffered packet queue,
|
|
|
|
thereby improving packet utilization, especially for small HTTP
|
|
|
|
messages.

Now this is only done once per connection, if the handshake is

successful and -a option is given.
|
|
|

close it immediately instead of waiting until the end of the tick.

processed in the same tick instead of waiting for the next one.

The change puts a 1-second limit on the amount of time the engine

will not send packets after some packets are delayed. This makes

the library robust in case the user does not unblock the engine

|
|
Packets on the scheduled queue may be marked for repackaging.
|
|
|
|
Frames such as ACK frame that are never resent are removed from
|
|
|
|
repackaged packets. We must check that the newly repackaged packet
|
|
|
|
would not be empty. If it would be, it is destroyed instead and
|
|
|
|
the next packet on the scheduled queue is used. Note that this
|
|
|
|
change only affects the logic to return the next packet to be sent.
|
|
|
|
Lost packets that are being rescheduled are already processed in
|
|
|
|
this fashion.

2. A connection is tickable if there are streams on the servicing

independent of whether any packets are sent.

[API Change, OPTIMIZATION] Only process conns that need to be processed
|
|
|
|
|
|
|
|
The API is simplified: do not expose the user code to several
|
|
|
|
queues. A "connection queue" is now an internal concept.
|
|
|
|
The user processes connections using the single function
|
|
|
|
lsquic_engine_process_conns(). When this function is called,
|
|
|
|
only those connections are processed that need to be processed.
|
|
|
|
A connection needs to be processed when:
|
|
|
|
|
|
|
|
1. New incoming packets have been fed to the connection.
|
|
|
|
2. User wants to read from a stream that is readable.
|
|
|
|
3. User wants to write to a stream that is writeable.
|
|
|
|
4. There are buffered packets that can be sent out. (This
|
|
|
|
means that the user wrote to a stream outside of the
|
|
|
|
lsquic library callback.)
|
|
|
|
5. A control frame (such as BLOCKED) needs to be sent out.
|
|
|
|
6. A stream needs to be serviced or delayed stream needs to
|
|
|
|
be created.
|
|
|
|
7. An alarm rings.
|
|
|
|
8. Pacer timer expires.
|
|
|
|
|
|
|
|
To achieve this, the library places the connections into two
|
|
|
|
priority queues (min heaps):
|
|
|
|
|
|
|
|
1. Tickable Queue; and
|
|
|
|
2. Advisory Tick Time queue (ATTQ).
|
|
|
|
|
|
|
|
Each time lsquic_engine_process_conns() is called, the Tickable
|
|
|
|
Queue is emptied. After the connections have been ticked, they are
|
|
|
|
queried again: if a connection is not being closed, it is placed
|
|
|
|
either in the Tickable Queue if it is ready to be ticked again or
|
|
|
|
it is placed in the Advisory Tick Time Queue. It is assumed that
|
|
|
|
a connection always has at least one timer set (the idle alarm).
|
|
|
|
|
|
|
|
The connections in the Tickable Queue are arranged in the least
|
|
|
|
recently ticked order. This lets connections that have been quiet
|
|
|
|
longer to get their packets scheduled first.
|
|
|
|
|
|
|
|
This change means that the library no longer needs to be ticked
|
|
|
|
periodically. The user code can query the library when is the
|
|
|
|
next tick event and schedule it exactly. When connections are
|
|
|
|
processed, only the tickable connections are processed, not *all*
|
|
|
|
the connections. When there are no tick events, it means that no
|
|
|
|
timer event is necessary -- only the file descriptor READ event
|
|
|
|
is active.
|
|
|
|
|
|
|
|
The following are improvements and simplifications that have
|
|
|
|
been triggered:
|
|
|
|
|
|
|
|
- Queue of connections with incoming packets is gone.
|
|
|
|
- "Pending Read/Write Events" Queue is gone (along with its
|
|
|
|
history and progress checks). This queue has become the
|
|
|
|
Tickable Queue.
|
|
|
|
- The connection hash no longer needs to track the connection
|
|
|
|
insertion order.

|
- [OPTIMIZATION] Merge series of ACKs if possible
|
|
|
|
|
|
|
|
Parsed single-range ACK frames (that is the majority of frames) are
|
|
|
|
saved in the connection and their processing is deferred until the
|
|
|
|
connection is ticked. If several ACKs come in a series between
|
|
|
|
adjacent ticks, we check whether the latest ACK is a strict superset
|
|
|
|
of the saved ACK. If it is, the older ACK is not processed.
|
|
|
|
|
|
|
|
If ACK frames can be merged, they are merged and only one of them is
|
|
|
|
either processed or saved.
|
|
|
|
|
|
|
|
- [OPTIMIZATION] Speed up ACK verification by simplifying send history.
|
|
|
|
|
|
|
|
Never generate a gap in the sent packet number sequence. This reduces
|
|
|
|
the send history to a single number instead of potentially a series of
|
|
|
|
packet ranges and thereby speeds up ACK verification.
|
|
|
|
|
|
|
|
By default, detecting a gap in the send history is not fatal: only a
|
|
|
|
single warning is generated per connection. The connection can continue
|
|
|
|
to operate even if the ACK verification code is not able to detect some
|
|
|
|
inconsistencies.
|
|
|
|
|
|
|
|
- [OPTIMIZATION] Rearrange the lsquic_send_ctl struct
|
|
|
|
|
|
|
|
The first part of struct lsquic_send_ctl now consists of members that
|
|
|
|
are used in lsquic_send_ctl_got_ack() (in the absense of packet loss,
|
|
|
|
which is the normal case). To speed up reads and writes, we no longer
|
|
|
|
try to save space by using 8- and 16-bit integers. Use regular integer
|
|
|
|
width for everything.
|
|
|
|
|
|
|
|
- [OPTIMIZATION] Cache size of sent packet.
|
|
|
|
|
|
|
|
- [OPTIMIZATION] Keep track of the largest ACKed in packet_out
|
|
|
|
|
|
|
|
Instead of parsing our own ACK frames when packet has been acked,
|
|
|
|
use the value saved in the packet_out structure when the ACK frame
|
|
|
|
was generated.
|
|
|
|
|
|
|
|
- [OPTIMIZATION] Take RTT sampling conditional out of ACK loop
|
|
|
|
|
|
|
|
- [OPTIMIZATION] ACK processing: only call clock_gettime() if needed
|
|
|
|
|
|
|
|
- [OPTIMIZATION] Several code-level optimizations to ACK processing.

Latest changes
- [API Change] Sendfile-like functionality is gone. The stream no
longer opens files and deals with file descriptors. (Among other
things, this makes the code more portable.) Three writing functions
are provided:
lsquic_stream_write
lsquic_stream_writev
lsquic_stream_writef (NEW)
lsquic_stream_writef() is given an abstract reader that has function
pointers for size() and read() functions which the user can implement.
This is the most flexible way. lsquic_stream_write() and
lsquic_stream_writev() are now both implemented as wrappers around
lsquic_stream_writef().
- [OPTIMIZATION] When writing to stream, be it within or without the
on_write() callback, place data directly into packet buffer,
bypassing auxiliary data structures. This reduces amount of memory
required, for the amount of data that can be written is limited
by the congestion window.
To support writes outside the on_write() callback, we keep N
outgoing packet buffers per connection which can be written to
by any stream. One half of these are reserved for the highest
priority stream(s), the other half for all other streams. This way,
low-priority streams cannot write instead of high-priority streams
and, on the other hand, low-priority streams get a chance to send
their packets out.
The algorithm is as follows:
- When user writes to stream outside of the callback:
- If this is the highest priority stream, place it onto the
reserved N/2 queue or fail.
(The actual size of this queue is dynamic -- MAX(N/2, CWND) --
rather than N/2, allowing high-priority streams to write as
much as can be sent.)
- If the stream is not the highest priority, try to place the
data onto the reserved N/2 queue or fail.
- When tick occurs *and* more packets can be scheduled:
- Transfer packets from the high N/2 queue to the scheduled
queue.
- If more scheduling is allowed:
- Call on_write callbacks for highest-priority streams,
placing resulting packets directly onto the scheduled queue.
- If more scheduling is allowed:
- Transfer packets from the low N/2 queue to the scheduled
queue.
- If more scheduling is allowed:
- Call on_write callbacks for non-highest-priority streams,
placing resulting packets directly onto the scheduled queue
The number N is currently 20, but it could be varied based on
resource usage.
- If stream is created due to incoming headers, make headers readable
from on_new.
- Outgoing packets are no longer marked non-writeable to prevent placing
more than one STREAM frame from the same stream into a single packet.
This property is maintained via code flow and an explicit check.
Packets for stream data are allocated using a special function.
- STREAM frame elision is cheaper, as we only perform it if a reset
stream has outgoing packets referencing it.
- lsquic_packet_out_t is smaller, as stream_rec elements are now
inside a union.
