Scalable GTP-C & U, V1 & V2 protocol load, feature and security testing solution for all interfaces including wireline, mobile 4G/5G and IoT
Overview
GPRS Tunnelling Protocol (GTP) is an IP -based protocol that carries session information between nodes within a Mobile network. GTP consists of three separate sub-protocols, GTP-C, GTP-U and GTP'. GTP-C is used between SGSN and GGSN in 3G and between SGW and PGW in 4G to create, modify and delete sessions or PDP contexts. GTP-U is used between the RAN and the core network to carry the user-plane (U-plane) IPv4 or IPv6 data from the UE. GTP' (GTP prime) is used between the CDF and CGF to carry charging information. GTP uses either UDP or TCP transport protocol and there are different versions including v0, v1 and v2. The Valid8 GTP Load Tester provides testing capabilities across numerous GTP interfaces in fixed and mobile networks such as S2b, S5, S10, S11, Gn
What It Can Do For You
It can test fuzzing, security, feature and performance on single or multiple GTP interfaces concurrently, generating tens of thousands of transactions per second (scalable per machine), with customizable message flows and content.
Diameter Load Tester comes with pre-canned scenarios which can be tailored to specific requirements.
Why It’s Different
- Scalable software-based architecture can run on a range of hardware from COTS and high-end customer provided hardware to Virtual Machines and the Cloud (e.g. Amazon AWS) for maximum versatility and performance
- Web-based UI is easy to learn
- HTTP API enable integration with automation test systems and other equipment
- Stateful modeling provides accurate emulation of network elements
Features
- Measure Key Performance Indicators (KPIs) such as number of simultaneous sessions and Busy Hour Call Attempts (BHCA)
- Check transaction content correctness
- Check load capabilities
- Generate valid and invalid/negative messages and call-scenarios
- Supports sending invalid responses including malformed, dropped and misordered packets
- Security testing

Use Cases
PGW Under Test
For testing the PGW, the 4G Network Emulator can wrap around the node using the S5/8, S7, Sxx and SGi interfaces. Traffic can be originated from real or emulated UE and IoT devices.
Supported Scenarios:
- Create Session
- Delete Session
- Create Bearer
- Modify Bearer
- Delete Bearer
- Echo
- Emulates all required nodes for wrapping around, including MME and PCRF for testing over interfaces S5/8, S7, Sxx nd SGi
- Exposes all internal interfaces
- Conformance tests available for each interface (S5/8, S7, Sxx, SGi)
MME Under Test
For testing MME, the HSS emulator can provide a realistic, stateful emulation of the subscriber DB for testing purposes
Supported Scenarios:
- Attach
- Detach
- Location Update
