A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session Initiation Proposal Investigation Working Group of the IETF.


	Title           : Design Considerations for Session Initiation Protocol (SIP) Overload Control
	Author(s)       : V. Hilt
	Filename        : draft-ietf-sipping-overload-design-00.txt
	Pages           : 19

Overload occurs in Session Initiation Protocol (SIP) networks when
SIP servers have insufficient resources to handle all SIP messages
they receive.  Even though the SIP protocol provides a limited
overload control mechanism through its 503 (Service Unavailable)
response code, SIP servers are still vulnerable to overload.  This
document discusses models and design considerations for a SIP
overload control mechanism.
