In this document, we propose a new multicast session directory system, «Channel Reflector». One of the goals of this system is to provide a feasible channel announcement mechanism for Source-Specific Multicast (SSM) environment without using traditional SAP advertisement. The main advantage of it is to provide a channel announcement policy and a data distribution area by effective scoping technique. Channel Reflector does not require any protocol change to an end user, therefore, the easy deployment is also one of the benefits. The channel information including the policy configurati- on is written in XML format. Due to an XML's property, network administrators can flexibly prepare independent channel information, and the end user retrieves available channel information as a human-readable information transparently.
