Abstract

Abstract:

Femto is a small base station placed in the room，capable of carrying voice，video，Internet and other business. This paper researched QoS problems in Femto backhaul network. First，it pointed out the demand of QoS guarantee in Femto backhaul network，then it analyzed the feasible QoS deployment schemes in Femto backhaul network. Meanwhile，combining with Femto application scenarios，it specifically discussed QoS differentiated service strategies，and present corresponding optimization proposals.

Key words: Femto, QoS, VLAN, diffServ, MPLS
