  1. How Packet Based Methodsare addressed by Q13 Frequency Sync Time/Phase Sync Work flow Traditional ToD(e.g. “10-100 ms”) Phase/Time(e.g. “0.1-1 ms”) Accurate Phase/Time(e.g. “0.5 – 3 ms”) Application CES (“traffic masks”) PNT (“sync mask”) PNT (“x ppb”) Requirements Target Requirements (G.pactiming-bis) Sync Methods (G.pactiming-bis) Network Limits (G.pactiming-bis) Target Requirements (G.8261) Sync Methods (G.8261) Network Limits (G.8261) General Requirements Performance Related aspects Packet based methods Arrangement Basic Requirements (Independent from protocols) End-to-end Network Architecture (G.8265) Network Modelling (8265) Clock Spec. (G.paclock-ter) Equipment Functions (G.8265) Network Architecture (G.8261) Network Modelling (G.8264) Clock Spec. (G.8263) Equipment Functions (G.8261, G.8264) With support from Network Nodes End-to-end Implementations with PTP, NTP, Others (“Telecom Profiles”) (G.8264) - Performance related aspects (G.8264, G.8263?, G.8261? ) Implementations with PTP, NTP, Others(“Telecom Profiles”) (G.8265) - Performance related aspects (G.8265) Specific requirements (dependent on protocols) With support from Network Nodes Outside Q13 scope (e.g. IETF, IEEE) Protocols details Protocols Definition Study area tecnhically relevant Study area could be technically relevant but probably is of lower interest Inputs from other standardization bodies Study area relates to a challenging scenario (technically possible in special cases)
