Twisted Pair: Low-level Networking

Twisted can do low-level networking, too.

Here's an example that tries to show the relationships of different classes and how data could flow for receiving packets.

FileWrapper

   v
PcapProtocol  TuntapPort
   |            |
   +------------+
   v
EthernetProtocol
   |
   +------------+-----------+---...
   v            v           v
IPProtocol    ARPProtocol  IPv6Protocol
   |
   +-------------+----------------+---...
   v             v                v
RawUDPProtocol  RawICMPProtocol  RawTCPProtocol
   |
   v
DatagramProtocol

Of course, for writing, the picture would look pretty much identical, except all arrows would be reversed.
