Ovum & Huawei worked out the Experience-Centric Transport Network Solution, Helps in Maintaining High User Experience and Network Performance Key Message 1. The transport network should give a good user experience with low packet loss and latency. Future 5 G services will have even more stringent performance requirements. 2. 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. 3. Transtion to a new network architectyre would require a change in an operational procedure … Scan for whitepaper download
