17.5 ECSCM
17.5.1 Introduction to ECSCM
ECSCM (EgdeCore Security Control Multicast) technology mainly includes three
aspects, i.e. Multicast Packet Source Controllable, Multicast User Controllable and
Service-Oriented Priority Strategy Multicast.
The Multicast Packet Source Controllable technology of Security Controllable
Multicast technology is mainly processed in the following manners:
1
.
On the edge switch, if source under-control multicast is configured, then only
multicast data from specified group of specified source can pass.
2
.
For RP switch in the core of PIM-SM, for REGISTER information out of specified
source and specified group, REGISTER_STOP is transmitted directly and table
entry is not allowed to set up. (This task is implemented in PIM-SM model).
The implement of Multicast User Controllable technology of Security Controllable
Multicast technology is based on the control over IGMP report message sent out by the
user, thus the model being controlled is IGMP snooping and IGMP model, of which the
