26 OFC 2019 • 3–7 March 2019 Explanation of Session Codes

M1C.4

Day Of The Week Number S = Sunday (Presentation order M=Monday within the session) Tu=Tuesday W=Wednesday Th=Thursday Session Designation Series Number (alphabetically) 1 = First series of sessions in day 2 = Second series of sessions in day

The first letter of the code denotes the day of the week (Sunday=Sunday, Monday=M, Tuesday=Tu, Wednesday=W, Th=Thursday) . The second element indicates the session series in that day (for instance, 1 would denote the first parallel sessions in that day) . Each day begins with the letter A in the third element and continues alphabetically through a series of parallel sessions . The lettering then restarts with each new series . The number on the end of the code (separated from the session code with a period) signals the position of the talk within the session (first, second, third, etc .) . For example, a presentation coded M1C 4. indicates that this paper is being presented on Monday (M) in the first series of sessions (1), and is the third parallel session (C) in that series and the fourth paper (4) presented in that session .

Thus a new scenario is emerging following current attempts by the Telecom and Network operators to emancipate themselves from the system vendor lock-in. Vertical integration of network equipment, where vendors provide support during the entire lifecycle of their product, seems to be no longer the common requirement in the Network Disaggregation paradigm.

How system integration and all other mentioned issues can be faced in the disaggregation challenge and how the ICT network market will consequently evolve while maintaining interoperability and reliability is part of the current debate and will be part of the main topics during the Open Platform Summit event.
