“…Furthermore, Chen et al suggest that intermediate nodes along a connection should have the ability to add information to the OAM cell. This extended function facilitates measurements of CTD/CDV (see section 4.1) without clock synchronization and a more detailed analysis of information collected along a connection that comprises several nodes [Chen1]. A model for estimation of CDV and CTD without clock synchronization has been put forward by C. Roppel exploiting round-trip measurements with OAM cells and a model for estimation of the differences between the clocks [Roppel].…”

Abstract. The introduction of switched virtual connections and valueadded services in ATM networks create new conditions for network management. A general model for performance management in switched broadband networks, based on interaction between management functions and control functions, is presented in this paper. Quality-of-service management in the service domain is also considered. Finally, in-service methods for monitoring of network performance (especially cell losses) in switched ATM networks are covered in more detail.

“…The lower bound has been proposed by ITU-T for terrestrial connections. A much stricter two-way delay bound (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) ms is required for voice calls using analog terminals, which includes 95 of all phones [2]. Longer delays generate significant talker echo due to impedance mismatches at the subscriber loop [5].…”

“…Such waste may become significant when video applications become more robust and can tolerate cell loss rates approaching 1 [26]. Finally, time-stamped operation and maintenance (OAM) cells [27] are periodically injected into the traffic stream in order to estimate end-to-end CTD/CDV. This transmission and processing overhead is not required with DFQ since all cells which reach their destination must by definition meet the CTD/CDV bounds that were specified.…”

Abstract-A transmission and multiplexing strategy appropriate for voice over asynchronous transfer mode (ATM), called delayed frame queueing (DFQ), is proposed. This frame-based strategy has features in common with the synchronous transfer mode and is thus well suited to service synchronous applications such as voice, while retaining the statistical multiplexing capabilities of ATM. In particular, the DFQ service discipline can provide explicit and nontrivial bounds for queue delay and jitter, for both bursty as well as continuous traffic streams. Furthermore, the DFQ discipline can combine a wide range of delay and jitter bounds while also managing the distribution of quality of service violations among the traffic streams when congestion occurs. Jitter control is performed at the network periphery and thus does not negatively influence multiplexing gain at intermediate nodes. This efficient strategy has major implications in terms of the preferred alternatives chosen by clients when implementing source clock recovery for voice. DFQ allows the entire range of implementation alternatives for voice over ATM to be appropriately serviced, such as ATM adaptation layer types 1 and 2 (AAL1/2), adaptive playout, and immediate playout.

Asynchronous transfer mode (ATM) network management is an urgent issue for the fast and successful proliferation of ATM networks. Especially, performance management of ATM virtual connections is urgently required because a different quality of service should be guaranteed on each connection. In most cases, the customer's virtual connections traverse multiple subnetworks, therefore, performance information related to specific user connection is distributed in the networks. This makes performance management of ATM network more difficult. In order to obtain this distributed performance information with current ATM-related management information bases (MIBs), interactions among managers and frequent polling of switches are inevitable. This frequent polling and manager to manager interactions may cause management traffic and data retrieval time to increase. In this article, we propose a performance management method using OAM MIB. The MIB is a set of managed objects which have the information provided by OAM (Operation Administration and Maintenance') cells. The basic concept and structure of the MIB are similar to the RMON MIB. By using the OAM MIB, management traffic and manager to manager interactions are much reduced. In our model, customer network management system (NMS) accesses the MIB via M1/M2 reference points of the ATM Forum management architecture with simple network management protocol (SNMF).
