Load balancing is a way of splitting up traffic onto multiple paths between two (or more) endpoints; effectively increasing capacity between those points. With some methods the maximum rate for a single transmission will be whatever the single component in that bundle is able to handle.
There's probably a few more lurking around than the ones I've listed below.. Not all are applicable everywhere, research the topics. - MLFR (both FRF.15 and FRF.16) - MLPPP - IMA ;) - "Etherchannel"/802.3ad - PVST/PVRST/MST - treat some vlans differently - Multiple HSRP groups - GLBP - Equal cost multipath (ECMP) using statics, RIP, ISIS, EIGRP, BGP, MPLS TE - Unequal cost multipath using EIGRP, BGP (dmzlink-bw), MPLS TE (multiple tunnels, different amount of BW on each) - Anycast - "load balancers" (in front of a web farm) - WCCP Regarding your example on two ISPs is more about managing inbound/outbound traffic volumes to your AS.. I guess you could consider that load balancing but I'd think it's more about capacity planning. Nuances, I guess ;-) Please start create a new thread using a new message instead of replying to someone else's.
