Performance Aspects of a Service at the Network Edge

Programmability opens the network interfaces for development of innovative applications which improve user experience and network performance. Enablers of network programmability include microservice-based architecture and cloud-native implementation. The functionality of the fifth generation core network is defined as services which support REpresentational State Transfer (REST) interfaces. Distributed cloud capabilities at the network edge also expose REST-based application programming interfaces (APIs). The paper presents the results of emulation of REST API aimed at performance evaluation. The focus is on latency injected by requests and the respective responses.
