Challenges
Not being able to create new services on Mobile network due to Scalability limitations of packet core Gateway.
Delay in the network deployments as Mobile Network was not supporting the bandwidth intensive services.
Solution
- L2TPv2 Tunneling between P-GW and PDN
- GTPU and L2TPv2 tunneling control and fast/user plane features on VPP platform
- Fast path manager/agent implementation for control to fast plane communication based on VPP binary interface
- DPI, charging, rule matching (e.g. 1. SDF derivation and PDR matching). QER processing in Fast Path
- 4G and 5G feature testing on local test bed and Spirent Setups
Outcomes
- Optimization of control to fast path communication by leveraging VPP platform using shared memory
- Feature implementation based on Control and User Plane Separation (CUPS architecture) of EPC nodes
