Description

Ultibo Network Transport Interface unit

Notes:

Includes all global transport definitions plus base class for Network transports.

Currently supported transports are IP, ARP, RARP, IPX and IP6.

All HostToNetwork swaps occur at the level where they are appropriate (ie the level of their header).

Bindings is provided to support Transports (such as IP) which can provide multiple addresses on a single adapter. It is not used by the Protocol or Winsock layer and is only used by the transport where appropriate. In such cases the ConfigType in the Adapter object is not used and the Binding is used instead.
