Event driven filter monitoring for IP multicast services
First Claim
1. A method for implementing a filter for use in receiving a multicast transmission, comprising:
- detecting a message, wherein the message comprises an address of a multicast group and a request to join the multicast group to receive a multicast transmission;
in response to detecting the message, determining a filter parameter needed to receive the multicast transmission; and
implementing the filter parameter to receive the multicast transmission.

Abstract
Event driven methods for implementing or removing a filter used in receiving a multicast transmission are disclosed. An exemplary method for implementing a filter includes: detecting a message, such as an IPv6 MLD message, wherein the message comprises an address of a multicast group and a request to join the multicast group to receive a multicast transmission; in response to detecting the message, determining a filter parameter (e.g., a PID number and/or MAC address) needed to receive the multicast transmission; and implementing the filter parameter to receive the multicast transmission. Alternative methods wherein filter implementation or removal is based on the detection of direct procedure calls, such as a Setsockopt call, are also disclosed.
