  22. Ovum & Huawei worked out the Experience-Centric Transport Network Solution, Helps in Maintaining High User Experience and Network Performance Key Message The transport network should give a good user experience with low packet loss and latency. Future 5G services will have even more stringent performance requirements. The service assurance technique would be improved from minutes or hours to seconds or subseconds to give network operators a good understanding & clear actions for problem remediation. Transtion to a new network architectyre would require a change in an operational procedure … Scan for whitepaper download
