Intra Autonomous System Overlay Dedicated to Communication Resilience
نویسندگان
چکیده
Some services delivered in IP networks, like IP television, Telephony over IP and critical services, have strong robustness requirements. Consequently, the communications delivering those services must be resilient to failures in the network. This paper proposes a new approach to improve communication protection. It consists in deploying a routing overlay dedicated to resilience in an autonomous system, and it reduces connectivity restoration time after a failure (compared to standard routing protocols). Finally, we validate this proposal under different scenarios on an emulated testbed.

FatNemo: Multisource Multicast Overlay Fat-Trees
High-bandwidth multisource multicast among widely distributed nodes is critical for a wide range of important applications including audio and video conferencing, multi-party games and content distribution. Multicast decouples the size of the receiver set from the amount of state kept at any single node and potentially avoids redundant communication in the network. The limited deployment of IP ...
متن کاملOn 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 کاملTowards Robust Overlay Networks: Enhancing Adaptivity Mechanisms with Byzantine-Resilience
Adaptive measurement-based overlay networks offer increased performance and resilience to benign failures for end-to-end communication by using aggressive adaptivity mechanisms. These mechanisms dynamically optimize applicationcentric metrics such as latency, jitter, bandwidth, and loss rate. However, end-systems are more vulnerable than core routers, making overlay networks susceptible to mali...
متن کاملMethods for Improving Resilience in Communication Networks and P2P Overlays
Resilience to failures and deliberate attacks is becoming an essential requirement in most communication networks today. This also applies to P2P Overlays which on the one hand are created on top of communication infrastructures, and therefore are equally affected by failures of the underlying infrastructure, but which on the other hand introduce new possibilities like the creation of arbitrary...
متن کاملAnonymous Communications on the Internet
For many internet applications, it may be advantageous or essential and even critical to protect the identity of participants. Anonymous communication strategies mostly shield the sender of messages from identification. This paper presents a protocol for anonymous communication over internet that can also provide receiver anonymity. Our system is designed to provide anonymity under a rather str...
