“…However, their system can only tolerate single server failure and does not provide real-time recovery when a server fails. Anker et al [11] presented a fault tolerant video on demand service by using multiple servers. Their system is built up on a group communication system called Transis, thus when a server crashes it is replaced by another server in a transparent way.…”

With the advances of compression technology, storage devices and networks, Video on Demand (VoD) service is becoming popular. The system needs to provide continuous service and heterogeneous service levels for users. However, these requirements cannot be satisfied in conventional VoD system which is constructed on redundant content servers and centralized management.In this paper, autonomous VoD system is proposed to meet the requirements. The system is constructed on Faded Information Field architecture. Under the proposed architecture, autonomous fault detection and fault recovery technologies are proposed to achieve faulttolerance for continuous service.The effectiveness of the proposed technologies are proved through simulation. The results show that an average of 30% improvement in recovery time and users' video service can be recovered without stopping compared with conventional VoD system.

“…Note that in contrast to partitionable systems, in primary-partition systems, such merge and split operations are not allowed -i.e., only a single partition can exist and all the non-faulty processes are required to agree on the composition of that partition [6], [26]. Collaborative applications [11], resource allocation management [7], and distributed monitoring [23] are examples of applications that support partitioning. Partitions may experiment with some eventual stability so that the liveness of the computation can be guaranteed -i.e., a stability period lasts long enough in order to eventually allow all the participant nodes of the partition to communicate in a timely manner.…”

With Mobile Ad hoc Networks (MANETs), communication between mobile users is possible without any infrastructure. MANETs are already a necessary part of wireless systems. Due to arbitrary node arrivals, departures, crashes and movements, network partitioning may arise resulting in a degradation of the service, but not necessarily in its interruption. In this paper, we propose a distributed system model for partitionable systems. We then specify and implement a partition-participant detector that captures the liveness of a partition even if the partition is not completely stable. Its role is to detect the minimal stability condition to guarantee that eventually all the stable processes in an α-Set elect the same leader.

“…View-oriented group communication systems are especially useful for constructing fault-tolerant applications that consistently maintain replicated state of some sort (examples include Keidar and Dolev 1996;Fekete et al 2001;Sussman and Marzullo 1998;Anker et al 1999;Khazan et al 1998;Friedman and Vaysburg 1997;Guerraoui and Schiper 1997b]). Such applications greatly benefit from virtually synchronous communication semantics (for example, [Moser et al· 3 WAN, as compared to the relative consistency of message latency in a local-area network (LAN).…”

We present Moshe, a novel scalable group membership algorithm built specifically for use in wide area networks (WANs), which can suffer partitions. Moshe is designed with three new significant features that are important in this setting: it avoids delivering views that reflect out-of-date memberships; it requires a single round of messages in the common case; and it employs a clientserver design for scalability. Furthermore, Moshe's interface supplies the hooks needed to provide clients with full virtual synchrony semantics. We have implemented Moshe on top of a network event mechanism also designed specifically for use in a WAN.In addition to specifying the properties of the algorithm and proving that this specification is met, we provide empirical results of an implementation of Moshe running over the Internet. The empirical results justify the assumptions made by our design and exhibit good performance. In particular, Moshe terminates within a single communication round over 98% of the time. The experimental results also lead to interesting observations regarding the performance of membership algorithms over the Internet.
