The problems are summarised as the increased storage state maintained by every member about every other member in the group, the feedback delay, and the bandwidth usage problem especially for receivers that obtain incoming RTCP reports through low bandwidth links. We designed a scheme to tackle these problems and to improve the RTCP scalability. Our scheme is based on a hierarchical structure in which members are grouped dynamically, into local regions and receiver reports (RRs) are sent with limited scope. As a result, the load is distributed among members in the group. Each region has an aggregator (AG) that receives the RRs feedback, performs some aggregation statistics on this control data, then sends these statistics to a manager. The manager performs additional analysis to evaluate the network performance and to estimate regions which are suffering from significant congestion. Finally, we present the benefits of using our scheme.","PeriodicalId":256339,"journal":{"name":"Proceedings Third IEEE Symposium on Computers and Communications. ISCC'98. (Cat.

SNMPv3 is now in its final stages of standardization. From a practical perspective, we need to consider how telecommunication systems can be extended to consider different versions of SNMP, different applications and different security models. We present an object-oriented implementation of SNMPv3 to create a flexible product architecture. This architecture allows one to easily interface with other modules as required. We also describe network object models and relationships required for the architecture. The implementation uses Java to create modular reusable components. We explain how the architecture using a modular approach can allow interoperability with other SNMP applications. Also, the systems can possibly connect via an API bus to CORBA, JMAPI or WBEM.","PeriodicalId":256339,"journal":{"name":"Proceedings Third IEEE Symposium on Computers and Communications. ISCC'98.

Collecting the topology and network state information to every node has become a popular approach (termed a link state protocol). Applying this technique introduces a problem of a large amount of data and information updates. In large networks it leads to hierarchical division of the network into smaller clusters. Our solution takes a different direction. It defines a vicinity around each node that is updated with the local node and link information. Outside the vicinity an hierarchical yet flexible structure of the border node is defined. The route is calculated up to the nearest border and from this point a new calculation is made. This new architecture eliminates the need of dividing the network into clusters, in particular solving the inefficiency when such a partition is done manually.","PeriodicalId":256339,"journal":{"name":"Proceedings Third IEEE Symposium on Computers and Communications.

A closed form expression for the FM discriminator output (or the instantaneous received frequency) is obtained when there are M reflected path signals in addition to the primary path signal. We derive the power spectral density when the multipath interference is weak, and determine the conditions under which multipath interference causes nonlinearities in the instantaneous frequency of the received signal. In order to verify our analytical results, we have built an SPW simulator of HSDS (the high speed data service) system, and we have observed close agreement between our analysis and simulations. The analytical techniques presented could potentially be applied to other FM subcarrier systems, as well as to digital wireless systems that adopt FSK or its variants. Hence, our results could be useful in understanding noncoherent reception of the GSM digital cellular system, for example.","PeriodicalId":256339,"journal":{"name":"Proceedings Third IEEE Symposium on Computers and Communications.

These are the switching functions, network survivability functions, sub-network management functions and the test access functions. In examining the switching functions for the cross-connection of the individual AU (administrative unit) and TU (tributary unit), the paper describes the switching steps and discusses the system capacity. The network survivability functions are described with reference to their importance in the public network. A method for the total network management function with sub-network management capabilities is suggested.
