PyTCP-net-proto 3.0.5

The network-protocol packet parse/assemble layer of the PyTCP stack — Ethernet through TCP/UDP — fully usable on its own.

PyTCP-net_proto

The network-protocol packet parse / assemble / validate layer of the PyTCP TCP/IP stack — extracted as its own distribution and usable on its own.

from net_proto import IpProto
from net_proto.protocols.udp.udp__parser import UdpParser

Why

Strict, RFC-grounded, fully-typed wire-format codecs for the common Internet protocols, with a single clean validation-error tree and no runtime dependencies beyond the address library it is built on.

Coverage

Ethernet II / 802.3 (LLC/SNAP), ARP, IPv4 (+ options), IPv6 (+ Hop-by-Hop / Destination-Options / Routing / Fragment extension headers), ICMPv4, ICMPv6 (incl. ND, MLDv2), TCP (+ options), UDP, DHCPv4 — each as a parser / assembler pair with header dataclasses, integrity + sanity validation, and typed protocol enums.

Install

pip install PyTCP-net_proto

Depends only on PyTCP-net_addr (the address value-type library) and aenum. Fully typed (ships py.typed, PEP 561).

Requirements

Python 3.14+.
