GTP Loss and Impact of Transport Bandwidth
Above is practical result of Transport Bandwidth Change impact and its difficult to isolate throgh OSS KPIs , It needs GTP analysis along with field testing 1. Site was already congested and >95% Radio Capacity was used 2. By Changing Transport BW from 200Mbps to 400Mbps site comsumes more 20% traffic with 110% Radio capacity used and better performance . 3. There is no impact seen in OSS KPIs but field test shows >85% throghput degradation. 4. Packet loss and Latency was all across reason for user experiance degradation. 5. One Major thumb rule that i came across that Transport BW > (Sum of Cell throughput of site ) * 118% What is GTP and GTP Loss ? 1. GPRS Tunneling protocol is an important IP based protocol used in GSM, UMTS and LTE core networks. It is used to encapsulate user data when passing through core network and also carries bearer specific signali...
