/*
|
|
|
|
* SoupBinTCP is a framing protocol published and used by NASDAQ to
|
|
|
|
* encapsulate both market data (ITCH) and order entry (OUCH)
|
|
|
|
* protocols. It is derived from the original SOUP protocol, which
|
|
|
|
* was ASCII-based, and relied on an EOL indicator as a message
|
|
|
|
* boundary.
|
|
|
|
*
|
|
|
|
* SoupBinTCP was introduced with OUCH-4.0 / ITCH-4.0 when those
|
|
|
|
* protocols also switched to using a binary representation for
|
|
|
|
* numerical values.
|
|
|
|
*
|
|
|
|
* The SOUP/SoupBinTCP protocols are also commonly used by other
|
|
|
|
* financial exchanges, although frequently they are more SOUP-like
|
|
|
|
* than exactly the same. This dissector doesn't attempt to support
|
|
|
|
* any other SOUP-like variants; I think it's probably better to have
|
|
|
|
* separate (if similar) dissectors for them.
|
|
|
|
*
|
|
|
|
* The only really complexity in the protocol is the message sequence
|
|
|
|
* numbering. See the comments below for an explanation of how it is
|
|
|
|
* handled.
|
|
|
|
*
|
|
|
|
* Specifications are available from NASDAQ's website, although the
|
|
|
|
* links to find them tend to move around over time. At the time of
|
|
|
|
* writing the correct URL is:

* acknowledges all important messages, so the client should use
|

* Packets from server to client are numbered, but it's implicit.
|
|
|
|
* The Login Accept packet contains the next sequence number that
|
|
|
|
* the server will send, and the client needs to count the
|
|
|
|
* Sequenced Data packets that it receives to know what their
|
|
|
|
* sequence numbers are.
|
|
|
|
*
|
|
|
|
* So, we grab the next sequence number from the Login Acceptance
|
|
|
|
* packet, and save it in a conversation_t we associate with the
|
|
|
|
* TCP session. Then, for each Sequenced Data packet we receive,
|
|
|
|
* the first time it's processed (when PINFO_FD_VISITED() is
|
|
|
|
* false), we write it into the PDU's frame's private data pointer
|
|
|
|
* and increment the saved sequence number (in the conversation_t).
|
|
|
|
*
|
|
|
|
* If the visited flag is true, then we've dissected this packet
|
|
|
|
* already, and so we can fetch the sequence number from the
|
|
|
|
* frame's private data area.
|
|
|
|
*
|
|
|
|
* In either case, if there's any problem, we report zero as the

|
* sequence number, and try to continue dissecting. */
