A method and apparatus for controlling a Report message processing load at
an IGMPv3 proxy/router. A variable governs a number
of current-state Group Records that can be sent in an IGMPv3 Report
message in response to a General Membership Query (GMQ). The
variable may be provisioned in IGMPv3 hosts, or
dynamically provided by the IGMPv3 proxy/routers, which embed the
variable in the GMQs.
