Book excerpt: Although it is widely known that the Internet is not prone to random failures, unplanned failures due to attacks can be very damaging. This prevents many organisations from deploying beneficial operations through the Internet. In general, the data is delivered from a source to a destination via a series of routers (i.e routing path). These routers employ routing protocols to compute best paths based on routing information they possess. However, when a failure occurs, the routers must re-construct their routing tables, which may take several seconds to complete. Evidently, most losses occur during this period. IP Fast Re-Route (IPFRR), Multi-Topology (MT) routing, and overlays are examples of solutions proposed to handle network failures. These techniques alleviate the packet losses to different extents, yet none have provided optimal solutions. This thesis focuses on identifying the fundamental routing problem due to convergence process. It describes the mechanisms of each existing technique as well as its pros and cons. Furthermore, it presents new techniques for fast re-routing as follows. Enhanced Loop-Free Alternates (E-LFAs) increase the repair coverage of the existing techniques, Loop-Free Alternates (LFAs). In addition, two techniques namely, Full Fast Failure Recovery (F3R) and fast re-route using Alternate Next Hop Counters (ANHC), offer full protection against any single link failures. Nevertheless, the former technique requires significantly higher computational overheads and incurs longer backup routes. Both techniques are proved to be complete and correct while ANHC neither requires any major modifications to the traditional routing paradigm nor incurs significant overheads. Furthermore, in the presence of failures, ANHC does not jeopardise other operable parts of the network. As emerging applications require higher reliability, multiple failures scenarios cannot be ignored. Most existing fast re-route techniques are able to handle only single or dual failures cases. This thesis provides an insight on a novel approach known as Packet Re-cycling (PR), which is capable of handling any number of failures in an oriented network. That is, packets can be forwarded successfully as long as a path between a source and a destination is available. Since the Internet-based services and applications continue to advance, improving the network resilience will be a challenging research topic for the decades to come.

Available in PDF, EPUB and Kindle. Book excerpt: Peer-to-Peer (P2P) networks have enabled a new generation of large scale distributed applications. Unlike the traditional client-server model, in a P2P network, all peers in the network both contribute to and receive services from the network. Due to their decentralized and self-organizing nature, P2P networks enable tens of thousands (potentially millions) of Internet machines to form virtual communities and share the vast resources aggregated from the participating machines. In this dissertation, we address a fundamental problem in designing P2P networks: How to construct and maintain a resilient infrastructure to provide reliable, scalable, and efficient routing service for millions of Internet nodes without central service and administration? The absence of central administration, the large number of nodes involved, and the high rate of node dynamics pose great challenges to the design of a resilient routing infrastructure for P2P networks. Our work tackles the above challenges and has successfully addressed the following problems: (1) How to design protocols to maintain ``consistency" of routing tables to ensure successful routing? (2) How to reason about correctness of these protocols? (3) How to evaluate the system's ability to sustain high rates of node dynamics and how to improve this ability? In particular, we have designed a suite of protocols that construct and maintain a resilient routing infrastructure. To base the protocol design on a sound foundation, we have introduced a theoretical foundation, called C-set trees, to guide protocol design and correctness reasoning. Based on the theoretical foundation, we have designed a join protocol and developed rigorous correctness proofs for the protocol. We have also designed an efficient failure recovery protocol, which has been demonstrated by extensive simulations to perform perfect recovery even when 50% of network nodes fail. Both the join protocol and the failure recovery protocol have been integrated into a single framework following a module composition approach. Furthermore, we have conducted extensive simulation experiments to study behaviors of the designed system under different rates of node dynamics (churn experiments). We find our system to be effective, efficient, and provide reliable and scalable routing service for an average node lifetime as low as 8.3 minutes (the median lifetime measured for two deployed P2P networks, Napster and Gnutella, was 60 minutes). Based on our system design, we have implemented a prototype system, named Silk, as the routing component of a shared infrastructure for P2P networks and other large-scale distributed applications.

Available in PDF, EPUB and Kindle. Book excerpt: The unending expansion of Internet-enabled services drives demand for higher speeds and more stringent reliability capabilities in the commercial Internet. Network carriers, driven by these customer demands, increasingly acquire and deploy ever larger routers with an ever growing feature set. The software however, is not currently structured adequately to preserve Non-Stop Operation and is sometimes deployed in non-redundant software configurations. In this dissertation, we look at current Routing Frameworks and address the growing reliability concerns of Future Internet Architectures. We propose and implement a new distributed architecture for next generation core routers by implementing N-Modular Redundancy for Control Plane Processes. We use a distributed key-value data store as a substrate for High Availability (HA) operation and synchronization with different consistency requirements. A new platform is proposed, with many characteristics similar to Software Defined Network, on which the framework is deployed. Our work looks at the feasibility of Non-Stop Routing System Design, where a router can continue to process both control and data messages, even with multiple concurrent software and hardware failures. A thorough discussion on the framework, components, and capabilities is given, and an estimation of overhead, fault recovery and responsiveness is presented. We argue that even though our work is focused in the context of routing, it also applies to any use-case where Non-Stop Real-Time response is required.
