VXDL™ Language

Virtual Infrastructure Description Language (VXDL™) is an open XML-based language that enables the modeling and description of virtual resources and virtual infrastructure. Initially developed by INRIA and Lyatiss, VXDL™ is proposed as an industry standard by the VXDLforum. With VXDL™ every element in the virtualized infrastructure and the dependencies linking them can be described. This includes not just the server and storage elements but also key network characteristics such as bandwidth and latency, so that end-to-end performance of applications and services is comprehensively supported. Network devices such as switches and access equipment can be modeled. Geolocation and security or availability constraints are also defined. VXDL™ descriptions integrate time as a variable, supporting dynamic infrastructure deployments.
