MAC Channeling

I am curious as to what context have you heard about MAC channeling? I might give you more insight. This is what I feel you might be referring to. Cisco uses the terminology channeling (as in EtherChannel) to describe Link Aggregation. This is afeature which cna be implemented on a network device, like a switch, where multiple ports are bundle to act as one. This is done to increase the bandwidth between two network devices. For instance, if you have a switch that is connected to your backbone switch using only 1 (100 MB) link and you want to increase the amount of available traffic to the backbone switch you can create a EtherChannel (Cisco) or Link Aggregation to bundle multiple ports together. IEEE 802.1ad is the Link Aggregation standard.
My assumption would be MAC channeling was refering to Link Aggregation or EtherChannel (Cisco).
