Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is part 2 of a multi-

15、part deliverable covering Performance Management aspects in “Satellite Earth Stations and Systems (SES); Broadband Satellite Multimedia (BSM)“, as identified below: Part 1: “Performance Management at the SI-SAP“; Part 2: “Performance Management Information Base“. Introduction The ETSI BSM Technical

16、Reports i.1, i.2 and i.3 outlined the general requirements for performance. Technical Specifications 1, 2 and 3 have subsequently defined the BSM Management Functional Architecture, the BSM Performance Parameters and Performance Management respectively. As a result of these documents, the focus of t

17、he present document is on the definition of a set of performance-related managed objects that can be used to manage a BSM sub-network. ETSI ETSI TS 102 675-2 V1.1.1 (2009-11)51 Scope The present document defines the requirements for management interfaces relating to Performance Management in BSM net

18、works, by providing an overview and guidelines for deriving a formal set of parameters (or managed objects) for one or more databases or MIB modules. These requirements are based on the concepts defined in 3. These parameters may be applied to one or more SNMP MIBs, for example. 2 References Referen

37、Background BSM performance parameters have been defined in 2 and these are used as the basis for the database objects defined in the present document. The performance parameters identified in 2 need to be calculated, in some cases, from QID elementary attributes, as it was described in 3. The locati

38、on of BSM databases and the way in which they may be accessed is described in 1 and 3. Figure 1 shows the overall management architecture. A database (MIB) in the ST stores parameter values as objects. Typically the BNMS would use SNMPv2c commands to obtain the parameter values from the ST MIB. An S

39、NMP agent in the ST responds to commands from an SNMP client in the BNMS. The ST MIB should support local management (through typically a user Ethernet interface) and remote management via the satellite.

41、(e.g. one or more MIBs) will allow: 1) Performance of individual STs to be monitored by accessing their MIBs. 2) Performance of the BSM from end-to-end to be monitored by accessing MIB parameters available in a central location such as the B-NMS (BSM Network Management System), and for these BSM per

42、formance MIB objects to be made available to other systems. The QID elementary attributes and the BSM performance parameters are further described below. 4.1 QID elementary attributes These are very basic QID attributes (such as packet counters and queue lengths) which can be used in practice to com

43、pute the QID-level and SI-SAP-level parameters, as described in 3. 4.2 QID-level Parameters (at an ST) These are the basic parameters which are related to the virtual queues at an SI-SAP, and can be extracted directly from measurements thereon or used to control them. Some of these parameters can be

44、 measured directly, some of them can be derived from more elementary QID attributes (described above). 4.3 SI-SAP-level Performance parameters (at an ST) These are parameters referring to the complete interface. Some of them need to be extracted from local measurements, some of them may be derived l

45、ocally or remotely form the QID-level parameters. 4.4 IP-level Performance parameters (BSM-wide) The BNMS may also create a database for access by other or higher level systems. This database contains end-to-end performance parameters derived from ST measurement parameters. These are termed IP perfo

46、rmance parameters below. The way in which these end-to-end BSM parameters may be measured and calculated is described in 3 and for example, could use IPFIX or RMON protocols. ETSI ETSI TS 102 675-2 V1.1.1 (2009-11)95 BSM MIB Definition 5.1 MIB Structure and groups The MIB-II 3 definition is taken as

47、 the basis for a BSM MIB. For BSM, two different MIB modules could be considered for location of the OIDs: A private MIB module (under iso.org.dod.internet.private.enterprises branch). MIB-II standard “interfaces“ module (under iso.org.dod.internet.mgnt.mib-2.interfaces branch). In MIB-II the interf

48、aces group defines a generic set of managed objects such that any lower-layer network interface to IP can be managed in an interface-independent manner through these managed objects. The interfaces group provides the means for additional managed objects specific to particular types of network interf

49、ace (e.g. the BSM SISAP) to be defined as extensions to the interfaces group for media-specific management. At this stage in the BSM specification, a private MIB only is considered, but it should be capable of compatibility with an interface MIB module. The location of the BSM vendor-specific MIB (vendor-specific RFC) within the MIB-II is shown diagrammatically as follows. enterprises(1)private (4)dod(6)internet(1)org(3)iso(1)Figure 2: Private MIB location (OIDs in brackets) Four sub-groups, syste
