Network Operator Independent Resilient Overlay for Mission Critical Applications
نویسندگان
چکیده
This paper proposes a Resilient Overlay for Mission Critical Applications (ROMCA); a novel operator-independent overlay architecture providing a resilient and reliable service across wide-area networks. Resilience is achieved by combining centralized topology construction control and distributed dynamic mapping of paths onto the overlay topology according to network conditions. ROMCA can mitigate the shortcomings of the underlying Internet network infrastructure and provide low recovery times in the event of network failure(s). Keywords-ROMCA; resilience; reliability; mission critical

On Designing the Overlay Topology of ROMCA (Resilient Overlay for Mission Critical Applications)
Inadequate end-to-end Quality of Service (QoS) and resilience support still exists across the Internet as it is difficult to achieve cooperation between the Autonomous Systems (AS) that are operated independently by Internet Service Providers (ISP). The use of an Overlay Network (ON) deployed on top of the Internet is viewed as one of the effective strategies to provide some measure of service ...
متن کاملNetwork-provider-independent overlays for resilience and quality of service
Overlay networks are viewed as one of the solutions addressing the inefficiency and slow evolution of the Internet and have been the subject of significant research. Most existing overlays providing resilience and/or Quality of Service (QoS) need cooperation among different network providers, but an inter-trust issue arises and cannot be easily solved. In this thesis, we mainly focus on network...
متن کاملTechnology challenges for virtual overlay networks
An emerging generation of mission-critical networked applications is placing demands on the Internet protocol suite that go well beyond the properties they were designed to guarantee. Although the “next generation internet” (NGI) is intended to respond to the need, when we review such applications in light of the expected functionality of the NGI, it becomes apparent that the NGI will be faster...
متن کاملGeoCast: An Efficient Overlay System for Multicast Applications
In this paper, we present GeoCast, a geographical location aware overlay network framework designed for providing efficient group communication services. GeoCast can be seen as an extension to the CAN network in the term of topology management and routing protocol. Geocast design has three important properties that attractive to group communication applications. First, it uses geographical mapp...
متن کاملMinimal broker overlay design for content-based publish/subscribe systems
Mission-critical distributed applications, such as Internet advertising platforms, increasingly utilize distributed publish/subscribe systems as a messaging substrate for information dissemination. These applications require low latency performance from the substrate, as the timely delivery of messages can have a direct impact on revenue. The cost of managing and operating distributed publish/s...
