Both CORBA and DDS follow different approaches, while CORBA is basically a Client / Server architecture, DDS follows the publisher/subscriber paradigm. However, IEDs generate different types of traffic that could be mapped to either CORBA, or DDS operations, leaving DDS for the most critical ones: the distribution of periodic samples values and substation events. The paper also analyses the behaviour of DDS for these types of operations.6enginfo:eu-repo/semantics/restrictedAccessconference output10.1109/IECON.2009.5415221Control and Systems EngineeringElectrical and Electronic Engineeringhttp://www.scopus.com/inward/record.url?scp=77951552854&partnerID=8YFLogxK
