I have been trying to find informations about these two terminologies (Asymmetric Protocol and Symmetric Protocol), but I could not find something useful.
Any help ?
((IGMP is an asymmetric protocol and is specified here from the point of view of a host, rather than a multicast agent)).
((MLD is an asymmetric protocol, specifying different behaviors for multicast listeners and for routers.For those multicast addresses))
Are the above (asymmetric protocol) related to "asymmetric routing" in the link below :
