Slide 1

Institutionalization of B-PON OSS-IF - Report of FSAN OAM-WG exercises - APNOMS2003 in Fukuoka October 3 rd , 2003 NTT Access Network Service Systems Laboratories Kenji Nakanishi nakanisi@ansl.ntt.co.jp NTT-AT Transport Network Division Tatsuhiko Yoshida tyoshida@trans.ntt-at.co.jp

Slide 2

Vendors can offer types of gear to any administrators diminishment of hazard Intents of institutionalization Internationally institutionalized determinations ( ex. ITU-T Recommendations ) Guarantee of interoperability Operators can buy types of gear from any merchants decrease of speculation Sharing advancement assets Market development by globalization Cost diminishment in an overall scale depicting standards specific for a specific framework Useful OSS-IF models

Slide 3

Basic guideline of PON Downstream : OLT appropriates all bundles to each ONU Each ONU extricates just the parcel tended to itself. Upstream : OLT doles out the transmitting timing of each ONU. Each ONU transmits its bundles as indicated by the planning.

B-PON OSS-IF Recommendations ・ The determinations depend on UML (Unified Modeling Language) Apr. 2001 Approved May. 2004 To be reconsidered - Unified to consolidated view - Addition of DBA capacities NW see ME definition <Q.834.2> NE see ME definition <Q.834.1> Managed Entity (ME) definitions Management display in view of UML portrayal <Q.834.3> Dec. 2001 Approved Oct. 2003 To be reconsidered - Addition of DBA capacities Protocol autonomous model CORBA determined Management show <Q.834.4> Protocol indicated demonstrate Jul. 2003 Approved Oct. 2003 To be changed - Addition of DBA capacities

Combining NE view and NW see NE view is valuable in the event of upkeep and testing NW view is helpful if there should arise an occurrence of provisioning FSAN proposed another view that consolidates the both perspectives The current Recommendations are separated into NE see (Q.834.1) and NW see (Q.834.2) The current Q.834.1 and Q.834.2 understand a joined view in deed by relating oversaw elements of both perspectives utilizing pointers A reconsidered Q.834.1 will incorporate the current Q.834.1 and Q.834.2, and will join NE view and NW see in deed and in addition in name.

Dynamic Bandwidth Assignment DBA: Dynamic Bandwidth Assignment Adopting to upstream bearing of PON. Sharing transfer speed between optical splitter and OLT. ONU can transmit upstream parcels as much as the data transmission licenses ONU-An ONU-B Optical splitter OLT ONU-C ONU-D Shared transfer speed Occupied data transfer capacity

UML depiction UML:Unified Modeling Language Suitable portrayal of question situated frameworks and programming advancement Relationship amongst OSS and its outer surroundings (High level prerequisites for OSS) Use case outline Sequence chart Time requested occasion depiction for every utilization case Detailed relationship between oversaw elements Class graph Q.834.3 is the primary ITU-T Recommendation that depicts situations utilizing UML entirely

Slide 17

Advantages of UML Modeling is important for - key segment of creating frameworks - excluding unnecessary points of interest, lessening multifaceted nature and encouraging comprehension - offering various perspectives with partition of concerns UML plans models with - intuitional and clear graphs - least and plain documentations
