Part 5-1: Transmission over networks –
General

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62379-5-1 has been prepared by technical area 4: Digital system interfaces and protocol of IEC technical committee 100: Audio, video and muiltimedia systems and equipment. The text of this standard is based on the following documents: CDV Report on voting 100/2107/CDV 100/2304/RVC

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) specify 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 media 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 62379-5-2 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, specifies 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 experienced by audio and video streams and in particular to the requirements of EBU ECN-IPM Measurements Group.

– 8 – IEC 62379-5-1:2014  IEC 2014 4 Network 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 messages 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 destination 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 Type definitions The following application-wide types shall be used:

5.4.1.2 netPortTable A table of network port descriptors for this unit. Each physical network port on the unit shall have a corresponding entry in this table. There may also be entries for "virtual" network ports. 5.4.1.3 netPortEntry An entry in the network port table. 5.4.1.4 nPortBlockId The block identifier for this port. Used as an index when accessing the network port table. SIST EN 62379-5-1:2014

IEC 62379-5-1:2014  IEC 2014 – 11 – 5.4.1.5 nPortName The name assigned to this port. This is an arbitrary text string assigned by the system manager. Such assignment should persist across resets of the unit. Until a name has been assigned, this object shall have a value that relates to a visible marking associated with the port's physical connector. Note that the name of a port on a network switch whose connector is labelled "2" on the unit's enclosure should default to a value such as "Port 2" or "Ethernet port 2" or "Front panel port 2". If it is connected to a network socket in, say, studio 6, a supervisor may then rename it as "Studio 6". 5.4.1.6 nPortState The current link-layer state of the port's network connection. If a management terminal sets this object to closing or linkDown, the managed unit shall reroute or, if that is not possible, gracefully close down all calls that pass through the port. In the case of closing, the port shall then enter the disabled state. For as long as the port is in linkDown state, the managed unit shall attempt to establish a network connection on the port. 5.4.1.7 nPortAddressType The type of network address used for nPortAddress. 5.4.1.8 nPortAddress An address which identifies the port. NOTE This will normally be the 48-bit MAC address of the interface. An IP address may be used if it is permanently assigned, but not if it is acquired via DHCP. 5.4.1.9 nPortPAddrType The type of network address used for nPortPartnerAddr. 5.4.1.10 nPortPartnerAddr In pointToPoint state, the address of the unit to which the port is connected. In sharedMedia state, the address of the unit which controls the local network to which the port is connected, e.g. wireless base station or clock master. In other states, the nPortPartnerAddr value is not defined by this standard. NOTE 1 This object is intended to allow a management terminal to "crawl" a network to discover its topology and what resources are present. The address allows it to make a management connection to the link partner in the case of a point-to-point link, or, in the case of a shared-media network segment, to a unit which may be able to supply a list of all the units on the segment. In contrast to nPortAddress, the nPortPartnerAddr value should identify the unit rather than its interface, so an EUI-64 is appropriate. NOTE 2 For some kinds of network segment, such as an Ethernet segment using CSMA/CD, there is no straightforward method for enumerating all the units present on the segment. 5.4.1.11 nPortBarred false (the default) if the unit is allowed to connect a route via the port; true if forbidden.

– 12 – IEC 62379-5-1:2014  IEC 2014 5.4.2 List of media sources 5.4.2.1 General The “list of sources” has an entry for each synchronous flow transmitted by the managed unit. The group of objects in Table 2 shall be implemented by all end equipment that can be the source for a synchronous flow, and by all switches. The root node for these objects shall be { iso(1) standard(0) iec62379(62379) network(5) general(1) networkMIB(1) callSources(2) } NOTE 1 Calls are always connected by the destination, so this table is read-only, apart from the ability to clear down a call from the source end. Management calls are not included in this list. NOTE 2 It is assumed that incoming calls specify a source in some way that may be at least partially network-dependent, and whenever a new connection is made an entry appears in this table, disappearing again when the call is released.
