Packet Decoder

Here some experiments around network parsers.

TCP/IP packets

• Ethernet II
• IPv4
• UDP

Custom packets

• SIMBA (FIX)

File formats

• PCAP

Usage

Tested with gcc-12.2.0:

$ ./build-n-run.sh <path/to/pcap/file>

Constraints

• unit tests are to be implemented
• there is a base parsing: assert()'s could be triggered on other dumps
• big-endian architecture is to be supported: static_assert()'s will be triggered
• only one SBE message is parsed in incremental packets: see WA_PARSE_ONE_MESSAGE macro
• SBE message data parsing is to be implemented: see WA_STUB_MESSAGE_DATA macro

Examples

• Input PCAP file
• Output Text file
