--- _id: '105' abstract: - lang: eng text: We initiate the study of network monitoring algorithms in a class of hybrid networks in which the nodes are connected by an external network and an internal network (as a short form for externally and internally controlled network). While the external network lies outside of the control of the nodes (or in our case, the monitoring protocol running in them) and might be exposed to continuous changes, the internal network is fully under the control of the nodes. As an example, consider a group of users with mobile devices having access to the cell phone infrastructure. While the network formed by the WiFi connections of the devices is an external network (as its structure is not necessarily under the control of the monitoring protocol), the connections between the devices via the cell phone infrastructure represent an internal network (as it can be controlled by the monitoring protocol). Our goal is to continuously monitor properties of the external network with the help of the internal network. We present scalable distributed algorithms that efficiently monitor the number of edges, the average node degree, the clustering coefficient, the bipartiteness, and the weight of a minimum spanning tree. Their performance bounds demonstrate that monitoring the external network state with the help of an internal network can be done much more efficiently than just using the external network, as is usually done in the literature. author: - first_name: Robert full_name: Gmyr, Robert last_name: Gmyr - first_name: Kristian full_name: Hinnenthal, Kristian id: '32229' last_name: Hinnenthal - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Christian full_name: Sohler, Christian last_name: Sohler citation: ama: 'Gmyr R, Hinnenthal K, Scheideler C, Sohler C.

Second, we develop a network based on the hypercube that maintains connectivity under adversarial DoS-attacks. For the DoS-attacks we use the notion of a Omega(log log n)-late adversary which only has access to topological information that is at least Omega(log log n) rounds old. Finally, we develop a network that combines both churn- and DoS-resistance. The networks gain their robustness through constant network reconfiguration, i.e., the topology of the networks changes constantly. Our reconguration algorithms are based on node sampling primitives for expanders and hypercubes that allow each node to sample a logarithmic number of nodes uniformly at random in O(log log n) communication rounds. These primitives are specific to overlay networks and their optimal runtime represents an exponential improvement over known techniques. Our results have a wide range of applications, for example in the area of scalable and robust peer-to-peer systems.' author: - first_name: Maximilian full_name: Drees, Maximilian last_name: Drees - first_name: Robert full_name: Gmyr, Robert last_name: Gmyr - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler citation: ama: 'Drees M, Gmyr R, Scheideler C.

In recent years, various self-stabilizing overlay networks have been proposed that have the advantage of being able to recover from any illegal state. However, the vast majority of these networks cannot give any guarantees on its functionality while the recovery process is going on. We are especially interested in searchability, i.e., the functionality that search messages for a specific identifier are answered successfully if a node with that identifier exists in the network. We investigate overlay networks that are not only self-stabilizing but that also ensure that monotonic searchability is maintained while the recovery process is going on, as long as there are no corrupted messages in the system. More precisely, once a search message from node u to another node v is successfully delivered, all future search messages from u to v succeed as well. Monotonic searchability was recently introduced in OPODIS 2015, in which the authors provide a solution for a simple line topology.We present the first universal approach to maintain monotonic searchability that is applicable to a wide range of topologies. As the base for our approach, we introduce a set of primitives for manipulating overlay networks that allows us to maintain searchability and show how existing protocols can be transformed to use theses primitives.We complement this result with a generic search protocol that together with the use of our primitives guarantees monotonic searchability.As an additional feature, searching existing nodes with the generic search protocol is as fast as searching a node with any other fixed routing protocol once the topology has stabilized. author: - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Alexander full_name: Setzer, Alexander id: '11108' last_name: Setzer - first_name: Thim Frederik full_name: Strothmann, Thim Frederik id: '11319' last_name: Strothmann citation: ama: 'Scheideler C, Setzer A, Strothmann TF.

We allow a current insider to have complete knowledge about the information system and to have the power to block any ϵ-fraction of its servers by a DoS attack, where ϵ can be chosen up to a constant. The task of the system is to serve any collection of lookup requests with at most one per nonblocked server in an efficient way despite this attack. Previously, scalable solutions were only known for DoS attacks of past insiders, where a past insider only has complete knowledge about some past time point t0 of the information system. Scheideler et al. [Awerbuch and Scheideler 2007; Baumgart et al. 2009] showed that in this case, it is possible to design an information system so that any information that was inserted or last updated after t0 is safe against a DoS attack. But their constructions would not work at all for a current insider. The key idea behind our IRIS system is to make extensive use of coding. More precisely, we present two alternative distributed coding strategies with an at most logarithmic storage overhead that can handle up to a constant fraction of blocked servers. author: - first_name: Martina full_name: Eikel, Martina last_name: Eikel - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler citation: ama: 'Eikel M, Scheideler C.

We show that in general it is impossible to provide monotonic searchability if corrupted messages are present in the system, which justifies the restriction to system states without corrupted messages. Furthermore, we provide a self-stabilizing protocol for the line for which we can also show monotonic searchability. It turns out that even for the line it is non-trivial to achieve this property. Additionally, we extend our protocol to deal with node departures in terms of the Finite Departure Problem of Foreback et. al (SSS 2014). This makes our protocol even capable of handling node dynamics. author: - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Alexander full_name: Setzer, Alexander id: '11108' last_name: Setzer - first_name: Thim Frederik full_name: Strothmann, Thim Frederik id: '11319' last_name: Strothmann citation: ama: 'Scheideler C, Setzer A, Strothmann TF.

There are a number of studies for safe node exclusion if the overlay is in a well-defined state, but almost no formal results are known for the case in which the overlay network is in an arbitrary initial state, i.e., when looking for a self-stabilizing solution for excluding leaving nodes. We study this problem in two variants: the Finite Departure Problem (FDP) and the Finite Sleep Problem (FSP). In the FDP the leaving nodes have to irrevocably decide when it is safe to leave the network, whereas in the FSP, this leaving decision does not have to be final: the nodes may resume computation when woken up by an incoming message. We are the first to present a self-stabilizing protocol for the FDP and the FSP that can be combined with a large class of overlay maintenance protocols so that these are then guaranteed to safely exclude leaving nodes from the system from any initial state while operating as specified for the staying nodes. In order to formally define the properties these overlay maintenance protocols have to satisfy, we identify four basic primitives for manipulating edges in an overlay network that might be of independent interest.' author: - first_name: Andreas full_name: Koutsopoulos, Andreas last_name: Koutsopoulos - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Thim Frederik full_name: Strothmann, Thim Frederik id: '11319' last_name: Strothmann citation: ama: 'Koutsopoulos A, Scheideler C, Strothmann TF.

In particular we give an algorithm, such that each node in a network discovers the address of any other node in the network. We model the knowledge of the nodes as a virtual overlay network given by a directed graph such that complete knowledge of all nodes corresponds to a complete graph in the overlay network. Although there are several solutions for resource discovery, our solution is the first that achieves worst-case optimal work for each node, i.e. the number of addresses (O(n)O(n)) or bits (O(nlog⁡n)O(nlog⁡n)) a node receives or sends coincides with the lower bound, while ensuring only a linear runtime (O(n)O(n)) on the number of rounds. author: - first_name: Sebastian full_name: Kniesburges, Sebastian last_name: Kniesburges - first_name: Andreas full_name: Koutsopoulos, Andreas last_name: Koutsopoulos - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler citation: ama: Kniesburges S, Koutsopoulos A, Scheideler C.

Despite up to \gamma n^{1/\log\log n} crashed servers, with \gamma>0 constant and n denoting the number of servers, our system can correctly process any batch of lookup and write requests (with at most a polylogarithmic number of requests issued at each non-crashed server) in at most a polylogarithmic number of communication rounds, with at most polylogarithmic time and work at each server and only a logarithmic storage overhead. Our system is based on previous work by Eikel and Scheideler (SPAA 2013), who presented IRIS, a distributed information system that is provably robust against the same kind of crash failures. However, IRIS is only able to serve lookup requests. Handling both lookup and write requests has turned out to require major changes in the design of IRIS. author: - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Alexander full_name: Setzer, Alexander id: '11108' last_name: Setzer - first_name: Martina full_name: Eikel, Martina last_name: Eikel citation: ama: 'Scheideler C, Setzer A, Eikel M.

Chord, in particular, has been studied thoroughly, and many variants of Chord have been presented that optimize various criteria. Also, several implementations of Chord are available on various platforms. Though Chord is known to be very efficient and scalable and it can handle churn quite well, no protocol is known yet that guarantees that Chord is self-stabilizing, i.e., the Chord network can be recovered from any initial state in which the network is still weakly connected. This is not too surprising since it is known that the Chord network is not locally checkable for its current topology. We present a slight extension of the Chord network, called Re-Chord (reactive Chord), that turns out to be locally checkable, and we present a self-stabilizing distributed protocol for it that can recover the Re-Chord network from any initial state, in which the n peers are weakly connected, in O(nlogn) communication rounds. We also show that our protocol allows a new peer to join or an old peer to leave an already stable Re-Chord network so that within O(logn)^2) communication rounds the Re-Chord network is stable again. author: - first_name: Sebastian full_name: Kniesburges, Sebastian last_name: Kniesburges - first_name: Andreas full_name: Koutsopoulos, Andreas last_name: Koutsopoulos - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler citation: ama: 'Kniesburges S, Koutsopoulos A, Scheideler C.

We consider a wireless network consisting of a set of n honest and reliable nodes within transmission (and interference) range of each other, and we model the external disruptions with a powerful adaptive adversary. This adversary may know the protocol and its entire history and can use this knowledge to jam the wireless channel at will at any time. It is allowed to jam a (1 − )-fraction of the timesteps, for an arbitrary constant > 0 unknown to the nodes. The nodes cannot distinguish between the adversarial jamming or a collision of two or more messages that are sent at the same time. We demonstrate, for the first time, that there is a local-control MAC protocol requiring only very limited knowledge about the adversary and the network that achieves a constant (asymptotically optimal) throughput for the nonjammed time periods under any of the aforementioned adversarial strategies. The derived principles are also useful to build robust applications on top of the MAC layer, and we present an exemplary study for leader election, one of the most fundamental tasks in distributed computing. author: - first_name: Baruch full_name: Awerbuch, Baruch last_name: Awerbuch - first_name: Andrea W. full_name: Richa, Andrea W. last_name: Richa - first_name: Christian full_name: Scheideler, Christian id: '20792' last_name: Scheideler - first_name: Stefan full_name: Schmid, Stefan last_name: Schmid - first_name: Jin full_name: Zhang, Jin last_name: Zhang citation: ama: Awerbuch B, Richa AW, Scheideler C, Schmid S, Zhang J.
