Deploying PTP as an Enterprise Service: Issues, challenges and design considerations

This paper presents an industry experience and research-based analysis of issues that the deployment of PTP as a service is facing in the finance industry, based on real life examples from a global stock exchange operator. It aims to summarise over three years of author's experience with deploying PTP, highlighting the most common problems encountered: standard specific, implementation specific and non-technical. The paper attempts to define some best practices for achieving high resiliency and service quality levels combined with ease of operation, also touching on design considerations for scalable timing networks. Finally, it makes recommendations for the industry, standard, for vendors and service providers, and presents some novel design concepts for timing networks, contributing to the relatively small public knowledge base.
