Implementace a evaluace protokolu CBOR

Kalvoda, Pavel

CBOR (RFC 7049) is a recent binary schema-less data serialization protocol similar to JSON and BSON. It introduces several novel concepts, such as explicit streaming support and extensible semantics. A robust, generic, standard-compliant implementation for C is developed and presented, along with its binding for the Ruby language. Both the implementation and the protocol itself are critically evaluated by both experimental and theoretical inquiries. The measurements show that the implementation achieves performance superior to relevant alternatives while still providing a rich set of features. CBOR offers functionality and efficiency on par with or superior to the alternatives. Both high- volume applications and constrained node systems might benefit from CBOR. Some of its features, however, were shown to be needlessly complex or impractical. Suggestions addressing these deficiencies are presented. Several other approaches to implementing CBOR are proposed and discussed. Powered by TCPDF (www.tcpdf.org)
