Transformation between XML and CBOR for network load reduction

Many systems use XML as a standardized information transfer between different components. The possibility to describe the data structure through definition documents enables both sender and receiver to validate information sent and received. However, the XML format requires relatively much bandwidth for a transfer via a network. This feature leads to a very high network load in case of applications with a huge amount of data to be transferred. The developed SIEM-like system from the SIMU project (www.simu-project.de) is based on the IF-MAP protocol and therefore uses the XML-based SOAP to represent and transfer data. To reduce network load, a technique was developed during the SIMU project, which allows a lossless transformation between XML and the relatively new specification called CBOR (RFC-7049). Thus, mobile terminals may be connected to such systems with high performance and low bandwidth usage.
