Base Protocol

pcapkit.protocols.transport.transport contains Transport, which is a base class for transport layer protocols, eg. TCP and UDP.

class pcapkit.protocols.transport.transport.Transport(file=None, length=None, **kwargs)

Bases: pcapkit.protocols.protocol.Protocol

Parameters

• proto (str) – next layer protocol name

• length (int) – valid (non-padding) length

Returns

instance of next layer

Return type
