As customer-owned and managed optical networks gain more popularity with large enterprises and institutions, the need to enable end-users to dynamically provision and configure network resources inspires the development of the second version of User Controlled Lightpath Provisioning System (UCLPv2). The UCLPv2 software is based on a service-oriented architecture in which network resources are e...

The last two decades have seen a lot of research on context-aware and context-oriented software development technologies, across subfields of computer science. This research area is slowly starting to mature and researchers currently explore how to unify di↵erent solutions proposed in these subfields. We envision that within another decade some of these solutions will make it into mainstream so...

End-to-end routing in connection-oriented broadband networks, which satisfies end-user quality of service (QoS) constraints, is an extremely complex problem. The complexity of the problem is compounded in multidomain, multi-provider networks for a number of reasons. For example, operators of some public networks may not wish to fully disclose their internal network topologies and a highly detai...

The objectives of a transport layer protocol include the setting up of an end-to-end connection, end-to-end delivery of data packets, flow control, and congestion control. There exist simple, unreliable, and connection-less transport layer protocols such as UDP, and reliable, byte-stream-based, and connection-oriented transport layer protocols such as TCP for wired networks. These traditional w...

Real-time traffic communication has Quality of Service (QoS) requirements such as end-to-end bandwidth and delay guarantees. We propose a novel frame-based QoS Scheduler, the frame-counter scheduler, for connection oriented packet switching networks. The frame-counter scheduler significantly reduces the end-to-end delay bound and buffer requirements provided by other frame-based schedulers. A f...

Delay tolerant-network is emerging technology in wireless communication. This network is applied generally when there is no end-to-end path from source to destination. In current TCP/IP technology communication is possible only when end-to-end path is available. But two major issues in DTN (Abbreviation) are routing and buffer management. Routing strategy determine which message should be forwa...
