text: "We propose two protocols for distributed priority queues (denoted by 'heap'
for simplicity in this paper) called SKEAP and SEAP. SKEAP realizes a distributed
heap for a constant amount of priorities and SEAP one for an arbitrary amount.
Both protocols build on an overlay, which induces an aggregation tree on which
heap operations are aggregated in batches, ensuring that our protocols scale even
for a high rate of incoming requests. As part of SEAP we provide a novel distributed
protocol for the k-selection problem that runs in time O(log n) w.h.p. SKEAP guarantees
sequential consistency for its heap operations, while SEAP guarantees serializability.
SKEAP and SEAP provide logarithmic runtimes w.h.p. on all their operations. \r\nSKEAP
and SEAP provide logarithmic runtimes w.h.p. on all their operations with SEAP
having to use only O(log n) bit messages."

text: "We investigate the maintenance of overlay networks under massive churn, i.e.\r\nnodes
joining and leaving the network. We assume an adversary that may churn a\r\nconstant
fraction $\\alpha n$ of nodes over the course of $\\mathcal{O}(\\log n)$\r\nrounds.
In particular, the adversary has an almost up-to-date information of\r\nthe network
topology as it can observe an only slightly outdated topology that\r\nis at least
$2$ rounds old. Other than that, we only have the provably minimal\r\nrestriction
that new nodes can only join the network via nodes that have taken\r\npart in
the network for at least one round.\r\n Our contributions are as follows: First,
we show that it is impossible to\r\nmaintain a connected topology if adversary
has up-to-date information about the\r\nnodes' connections. Further, we show that
our restriction concerning the join\r\nis also necessary. As our main result present
an algorithm that constructs a\r\nnew overlay- completely independent of all previous
overlays - every $2$\r\nrounds. Furthermore, each node sends and receives only
$\\mathcal{O}(\\log^3 n)$\r\nmessages each round. As part of our solution we propose
the Linearized DeBruijn\r\nSwarm (LDS), a highly churn resistant overlay, which
will be maintained by the\r\nalgorithm. However, our approaches can be transferred
to a variety of classical\r\nP2P Topologies where nodes are mapped into the $[0,1)$-interval."

text: We consider the problem of transforming a given graph G_s into a desired graph
G_t by applying a minimum number of primitives from a particular set of local
graph transformation primitives. These primitives are local in the sense that
each node can apply them based on local knowledge and by affecting only its 1-neighborhood.
Although the specific set of primitives we consider makes it possible to transform
any (weakly) connected graph into any other (weakly) connected graph consisting
of the same nodes, they cannot disconnect the graph or introduce new nodes into
the graph, making them ideal in the context of supervised overlay network transformations.
We prove that computing a minimum sequence of primitive applications (even centralized)
for arbitrary G_s and G_t is NP-hard, which we conjecture to hold for any set
of local graph transformation primitives satisfying the aforementioned properties.
On the other hand, we show that this problem admits a polynomial time algorithm
with a constant approximation ratio.

abstract:
- lang: eng
text: "We consider congestion control in peer-to-peer distributed systems. \r\nThe
problem can be reduced to the following scenario: Consider a set $V$ of $n$ peers
(called \\emph{clients} in this paper) that want to send messages to a fixed common
peer (called \\emph{server} in this paper).\r\nWe assume that each client $v \\in
V$ sends a message with probability $p(v) \\in [0,1)$ and the server has a capacity
of $\\sigma \\in \\mathbb{N}$, i.e., it can recieve at most $\\sigma$ messages
per round and excess messages are dropped.\r\nThe server can modify these probabilities
when clients send messages.\r\nIdeally, we wish to converge to a state with $\\sum
p(v) = \\sigma$ and $p(v) = p(w)$ for all $v,w \\in V$.\t\r\n\r\nWe propose a
\\emph{loosely} self-stabilizing protocol with a slightly relaxed legitimate state.
\ \r\nOur protocol lets the system converge from \\emph{any} initial state to
a state where $\\sum p(v) \\in \\left[\\sigma \\pm \\epsilon\\right]$ and $|p(v)-p(w)|
\\in O(\\frac{1}{n})$. \r\nThis property is then maintained for $\\Omega(n^{\\mathfrak{c}})$
rounds in expectation.\r\nIn particular, the initial client probabilities and
server variables are not necessarily well-defined, i.e., they may have arbitrary
values.\r\n\r\nOur protocol uses only $O(W + \\log n)$ bits of memory where $W$
is length of node identifiers, making it very lightweight.\r\nFinally we state
a lower bound on the convergence time an see that our protocol performs asymptotically
optimal (up to some polylogarithmic factor).\r\n"
