Outsourcing Home Network Authoritative Naming Service
draft-ietf-homenet-front-end-naming-delegation-08
Abstract
Designation of services and devices of a home network is not user
friendly, and mechanisms should enable a user to designate services
and devices inside a home network using names.
In order to enable internal communications while the home network
experiments Internet connectivity shortage, the naming service should
be hosted on a device inside the home network. On the other hand,
home networks devices have not been designed to handle heavy loads.
As a result, hosting the naming service on such home network device,
visible on the Internet exposes this device to resource exhaustion
and other attacks, which could make the home network unreachable, and
most probably would also affect the internal communications of the
home network.
As result, home networks may prefer not serving the naming service
for the Internet, but instead prefer outsourcing it to a third party.
This document describes a mechanisms that enables the Home Network
Authority (HNA) to outsource the naming service to the Outsourcing
Infrastructure.
