Job Description

Date: Nov 6, 2018



As a market leader in mobile network solutions, Ericsson is constantly working towards increasing performance of its systems. Our systems handle a major part of all mobile Internet traffic. More than 300 operators in 140 countries rely on our Evolved Packet Core solutions.

One of the products in Ericsson's portfolio is the Evolved Packet Gateway, EPG. The EPG sits in the middle of the Packet Core Network as a Gateway between the Radio network and the Internet. All traffic in a mobile network passes through this type of gateway and thus it has high requirement on scalability, robustness and performance. The EPG is implemented as a distributed real-time system that is split into a Control Plane and a Data Plane. The EPG runs on many different platforms - including carrier-grade Routers, Virtual Machines and Containers.


In 2017, we reached 40 Gbps and 2.6 million users per core. With demands on higher data throughput rapidly increasing, we need to continually boost the performance of our EPG.

Description of thesis

In 5G there is a need for extreme data rates; both in terms of total system throughput as well as peak user throughput. In addition to that the 5G Packet Core is adopting a Cloud Native deployment and architecture.


Within this area, we would like You to develop a Cloud Native load simulator that can both support these extreme data rates to load test the Packet Core User Plane (Data Plane) and be flexible enough to support many different deployments from minimalistic single-instance ones to large scale ones.


Areas of analysis/development:

  • Containers (Docker)
  • DPDK
  • Linux sockets
  • User-space packet processing
  • Packet Core Session Logic
  • Characteristics Verification (throughput, drops, etc.)
