Re: [EFM] RE: [EFM-OAM] Performance monitoring, installation, trouble shoot i...


I don't know what you mean by:
        "the collision of packets between the domains"
The only place within Ethernet that packets "collide" is:
        Within a single, half-duplex collision domain (i.e. CSMA/CD mode)
EFM will be a full duplex system so there will not be any collisions.

There is contention for positioning/ordering of packets in queues in switches. How that is done outside the scope of 802.3 completely and is generally considered to be a proprietary matter of implementation

Even though you carve out the service into their each partitioned VLAN  to "safely" transport the different services, I am still a bit fuzzy on:

1. How does this allow for a demand billing service?
2. Address the collision of packets between the domains?
