An automated service level manager (SLM) provides operations support for wide-area data communication services offered via regional IP-Over Ethernet on fiber networks The SLM comprises a suite of software components and associated hardware running the software, to communicate with agents throughout the networks, to accumulate various network operations data for reports and alarms and to provide instructions to control network operations The SLM preferably offers a web server type user interface This interface enables access by technical personnel of the carrier, for example from a network operations center This interface also offers access to customers having or seeking service through the network

Operations and provisioning systems for service level management in an extended-area data communications network

Wide-area data communications utilize regional networks transporting IP-over-Ethernet on fiber. For certain Layer 2 services, a regional implementation of the network makes limited use of spanning tree protocol on a backbone ring. Learning bridge operations in switches on associated access rings involve a short default for an aging timer. For use of Open Shortest Path First (OSPF), the connection of each access ring to the backbone ring uses a pair of routers with dual links therebetween. One of these links is bonded to the backbone (OSPF Area 0), whereas the other link is bonded to the Area of the respective access ring. Also, certain routers within each regional network form a mini-autonomous system, for boundary gateway protocol (BGP). The mini-autonomous systems of the regional networks form a confederation. The network utilizes route reflectors in the mini-autonomous systems. The Internet carries confederation commands to and from a designated hub.

Enhanced data switching/routing for multi-regional IP over fiber network

An Abstract of a Dissertation Submitted to Nova Southeastern University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Design and Implementation of a Prototype Toolset for Full Life-Cycle Management of Web-Based Applications by Joseph G. Gulla November 2002 The goal in this study was the design and prototype implementation of procedures, programs, views, schema, and data (toolset) for the management of Web applications. This toolset pertained to all phases of the Web application's life including design, construction, deployment, operation, and change. The toolset built upon key functional perspectives including accounting, administration, automation, availability, business, capacity, change, configuration, fault, operations, performance, problem, security, service level, and software distribution. The main problems addressed by the researcher through the toolset were the lack of support in a number of key areas such as keeping applications available and performing well, making applications easy to fix when they fail, making applications easier to change and maintain, and ensuring that applications are secure. The toolset addressed these challenges and at the same time reduced the impact of application complexity, the labor needed, and the skill required to achieve Web application manageability. Joint application design techniques were used for requirements and design activities. A rapid application design approach was used for toolset implementation, planning, and construction. Evaluation was done using a five-question survey that focused on input about the toolset's software attributes and technology, level of satisfaction with the toolset, and perceived contribution of the toolset to the organization. It is expected that this research project will be used as input for future service-based offerings for IBM's eBusiness Hosting line of business.

Design and Implementation of a Prototype Toolset for Full Life-Cycle Management of Web-Based Application

The contractual relation between customers and telecommunications service providers are becoming increasingly complex, due largely to changes in the marketplace and growth in the number and complexity of services on offer. In order to guarantee a certain quality of offered service and in response to customer needs, some mechanisms of service level management must be applied. The service level management in telecommunication networks is made by a agreement, established during the service subscription, which is used by customers and service providers to control the service level. This paper introduces a service level management system for ATM networks, which can be applied to different telecommunication systems.
