Introduction The present document is a consequence of the ETSI BSM report and recommendations on performance, availability and quality of
17、 service detailed in i.1. It was deemed to be important to have an own document about performance parameters even if this was not foreseen in i.1. BSM networks may be stand-alone domains, serving IP end-hosts located behind satellite terminals, but may often be connected to external terrestrial segm
18、ents. Users of BSM networks require their applications to run satisfactorily over the whole end-to-end path, and thus over the satellite links, as well as over the traversed terrestrial segments. The performance of the user applications can be derived by the network performance levels provided by th
19、e underlying networks traversed by the end-to-end path, and since the terrestrial segments connected to the BSM networks, often provide measurable network performance levels, it is fundamental to specify network performance levels for the BSM systems in the same way as for terrestrial networks. In a
20、ddition a network whose performance is not measurable cannot sell its services, thus the performance levels required from BSM networks need to be formalized in a set of performance parameters that can be used to check fulfilment of contractual agreements. ETSI ETSI TS 102 673 V1.1.1 (2009-11)51 Scop
21、e The present document defines performance parameters which will be used in BSM networks for the four functions mentioned below, i.e. for measuring performance, monitoring, controlling and analysing BSM systems. Performance management is meant by ITU as one of the five network management categories,
22、 FCAPS, as specified by the ITU-T Recommendation M.3400 i.4. So, adopting the ITU terminology, the present document focuses on “Performance Parameters“ as meant by the ITU and so all parameters relevant for the four remaining network management categories (Fault management, Configuration management,
23、 Accounting management and Security management) will not be considered here. ITU-T Recommendation M.3400 i.4 also defines performance management as consisting of the following functions: Performance Quality Assurance. Performance Monitoring. Performance Management Control. Performance Analysis. Thes
24、e parameters can be used, for example, by a BSM network manager to establish QoS levels for a given service, and monitor the “health“ of the BSM, or to “present“ the performance of the BSM network in order to assess compliancy to some contractual agreements. The parameters could be used as a basis f
25、or one or more MIBs. According to TR 121 905 i.23, “Network performance parameter values are usually derived from Quality of Service (QoS) parameter values“. Therefore BSM performance parameters will be derived from all QoS parameters relevant to BSM networks, namely from the classical parameters fo
26、r IP-based services, e.g. proposed by ITU i.4, as well as from more BSM-specific ones, coming from the definition of the BSM QoS architecture 1,2 and 3. Network performance parameters may be used for different purposes: they can be used only inside the BSM network or can be exposed to BSM external i
27、nterfaces; this will be also clarified in the present document. In the former case they will refer to SI-SAP properties (e.g. related to Queue Identifier (QID) and thus they are meant for BSM-internal use only; in the latter case they can be presented by the satellite network operator to the outside
28、 world (e.g. external terrestrial network operators connected to the BSM), e.g. to prove fulfilment of contractual agreements. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. square4 For a specific reference, su

43、have more than one IP address; however, a destination host is a unique association with a single IP address. Destination hosts also terminate higher layer protocols (e.g. TCP) when such protocols are implemented (taken from i.2). link: point-to-point (physical or virtual) connection used for transpo
44、rting IP packets between a pair of hosts. It does not include any parts of the hosts or any other hosts; it operates below the IP layer NOTE: For example, a link could be a leased line, or it could be implemented as a logical connection over an Ethernet, a frame relay network, an ATM network, or any
45、 other network technology that functions below the IP layer (taken from i.2); in the BSM case the whole satellite connection from the ingress ST to the egress ST can be defined as a link, if the satellite or the hub, connecting the two STs, do not implement the IP layer. host: computer that communic
46、ates using the Internet protocols NOTE: A host implements routing functions (i.e. it operates at the IP layer) and may implement additional functions including higher layer protocols (e.g. TCP in a source or destination host) and lower layer protocols (e.g. Ethernet) (taken from i.2). An ST is a par
47、ticular host which does not implement higher layer protocols. Measurement Point (MP): boundary between a host and an adjacent link at which performance reference events can be observed and measured (taken from i.2) NOTE: In general one Measurement Point (MP) for the performance parameters considered
48、 in a BSM network (also defined BSM MP) always coincides with one unique unicast IP address; so, where the SI-SAP is implemented (e.g. in an ST or in the hub), it also coincides with the unicast BSM_ID. Standard IP properties can be observed at BSM MPs, as well as SI-SAP specific properties, which a
49、re more related to SD events. Network Control Centre (NCC): equipment at OSI Layer 2 that controls the access of terminals to a satellite network, including element management and resource management functionality Network Performance (NP): ability of a network or network portion to provide the functions related to communications between users; it contributes to service accessibility, service retainability and service integrity NOTE: Network performance parameter va
