Description
Summary:Performance management (PM) is critical for supporting end-to-end QoS (Quality of Service) across long term evolution (LTE) network elements over heterogeneous networks. In order to effectively deliver QoS traffic from different applications, LTE can be delivered through implementation of logical Class of Service (CoS)/QoS controls in a variety of methods and with variety services. While LTE network domains (e.g., Evolved Universal Terrestrial Radio Access Network (E-UTRAN), Backhaul transport network, and Evolved Packet Core (EPC) network) can have different QoS implementations that work within a given domain, these differences can cause problems when domains intersect. Therefore, the design strategy must specifically and logically fit to allow multiple offers on limited network resources. This paper presents a high level PM system architecture for monitoring and troubleshooting harmonization of CoS/QoS based on 802.1p/DSCP (Diffserv Code Point)/EXP (EXPerimental bits) mappings that optimize end-to-end network performances over multiple LTE network elements.
