PITH (Policies for Internet Telephony over H.323)
Introduction
Approach
Results
The goal of this work was to develop policy support for communications using the
H.323 protocol stack (e.g. as used in Microsoft's NetMeeting). The project was
undertaken by Huang Tingxue under the supervision of Ken Turner and Stephan Reiff-Marganiec. Support was
provided by the Sino-British Fellowship Trust from April 2003 to April 2004.
Policy-based control of Internet Telephony was developed by the separate Accent project. Accent created protocol-independent
support of communication policies, and also an instantiation of this in a SIP
environment. Pith exploited the same policy infrastructure, but using H.323
as the communications mechanism. The idea is that H.323 and SIP calls should use
common policies that apply to any types of devices. Pith is using SIP and H.323
support provided by Vocal and GNU GK (H.323 Gatekeeper).
The technical basis of Pith is principally contained in the following published
papers:
