The e-book describes a style for developing types of telecom structures. the strategy is meant for working towards community architects and architects. this technique emphasizes modeling the (very complicated) practical constitution of networks in a fashion that's autonomous of any and software program layout method. the strategy additionally permits designers to specific their version in major perspectives: a ordinary view and a approach view that takes protocols and community configuration matters under consideration. the assumption is to continue a reliable view (the prevalent) within the context of continuing alterations and massive diversifications in the procedure view. the anticipated advantages are huge discount rates in telecom platforms improvement and upkeep. The terminology is area specific, i.e., in keeping with de-facto telecom terminology. All recommendations which are utilized in modeling are good outlined. the aim of utilizing a telecom-oriented terminology rather than industry-standard tools for software program and protocol layout (e.g., UML and SDL) is with a purpose to create types which are expressive and intelligible for community architects and architects. versions are created as graphical types that convey the useful and actual constitution of networks at diverse degrees of information. details on homes, together with habit is hooked up to the types. a pretty small set of symbols is utilized in modeling.

Since this is more less the idea with the OSI RM layer concept, one may ask what the difference is between a layer and a logical network. An important aspect of logical networks is that a particular type of layer interface is specified as a standardized and configurable interface (see Fig. 26). Logical node is n1 I Standardized and manageable layer interface Route that is created by the connectivity stratum CD CT5 CD OCDG:) en (T) CDCDCD CD CD CD CD & 0 COS Logical node is n2 ' Connectivity I stratum is COS Abstract COS S Logical network is nw={n1,n2} Fig.

We now call it AMLs. AMLs is a language that you may use to describe everything about an LSM. , it can be used for describing behavior of systems in any system domain. ) of state machines that AMLn introduces, but calls all of them abstract machines that may or may not include abstract objects. AMLs is described in details in Muth (2001). For readers who do not need all details of AMLs, a brief overview is given in Appendix D. You also need to specify LPM behavior, which comprises the messages of an agent layer protocol and the behavior of the agents.

SP). The L and N dimensions are applicable on all types of layers, including OSI layers. LM A LTA M ^1 I I I • III • N M NT Fig. L36 Main modeling dimensions. L=layer dimension; M=management dimension; N=node dimension When we work on an AMLn model we normally work only in one or sometimes in two dimensions. For example, taking the OSI RM model as a reference, we can either model it separately in the L and N dimensions, or apply a node structure on the L dimension and create a model in the L-N plane, as shown in Fig.
