scope:

This Recommendation specifies the traffic optimization control functions (TOCFs) and reference points between TOCF functional entities in support of steering traffic distribution according to certain optimization objectives in the environment of distributed service networking (DSN) and next generation networks (NGN). The TOCF supports application traffic optimization based on network awareness features (including topology information and traffic information) and provides capabilities for service providers (SPs) and network providers to work jointly to optimize the transfer of service traffic.
