25、 5 Transmission over networks 6 Packet transfer service 7 Measurement IEC 62379-1:2007, specifies aspects which are common to all equipment, and it includes an introduction to the common control interface. IEC 62379-2:2008, IEC 62379-3 (under consideration) and IEC 62379-4 (under consideration) spec

26、ify control of internal functions specific to equipment carrying particular types of live media. IEC 62379-4 refers to time-critical data such as commands to automation equipment, but not to packet data such as the control messages themselves. IEC 62379-5 specifies control of transmission of these m

27、edia over each individual network technology. It includes network specific management interfaces along with network specific control elements that integrate into the control framework. IEC 62379-5-1, (this standard) specifies management of aspects which are common to all network technologies. IEC 62

28、379-5-2 specifies protocols which can be used between networking equipment to enable the setting up of calls which are routed across different networking technologies. IEC 62379-5-3, onwards, specify management of aspects which are particular to individual networking technologies. IEC 62379-6, speci

29、fies carriage of control and status messages and non-audiovisual data over transports that do not support audio and video, such as RS232 serial links, with (as for IEC 62379-5) a separate subpart for each technology. IEC 62379-7 specifies aspects that are specific to the measurement of the service e

30、xperienced by audio and video streams and in particular to the requirements of EBU ECN-IPM Measurements Group.

36、twork service specifications 4.1 Service for live media Live media (including status broadcasts) shall be transmitted using a service for which, if the network supports it, guaranteed levels of throughput, delay, and data loss shall be requested. 4.2 Service for management messages Management messag

37、es should be transmitted in data units on an asynchronous flow as specified in IEC 62379-5-2. If no such service is available, a connectionless datagram service such as UDP may be used. Where a connection-oriented service is used, at least one call at each privilege level shall be accepted by a dest

38、ination unit at any given time. If more calls at one privilege level are accepted, this shall not prevent the acceptance of at least one call at each other privilege level. 5 MIB definitions applicable to all networks 5.1 General The structure of the MIB shall be as specified in IEC 62379-1. 5.2 Typ
