- Case: There is high percentage of SCTP Retransmission in the signaling link of X2 interfaces. It could affect all signaling X2 network procedure.
- Solution: We created a multi-vendor golden standard for SCTP Parameters. Then, apply it to the all X2 multi-vendor links. Transport QoS Validation. SCTP S1 validation it is required.
- Result: Reduce 65% of the X2 SCTP Retransmision. Reduction of the signaling links and association failures.
- Rollout was performed in all the AT&T network where was Overlay scenario. 2710 Nodes were configurated.
- Heat Map showed a significant improvement
- RTX decrease more than 65% which were unnecessary RTX in SCTP.
