The convergence of classical PSTN and IP networks requires the transport of SS7 signaling over IP. Since SS7 has very strict availability requirements for the signaling components, redundancy is mandatory. The goal of the IETF RSerPool working group is to define a lightweight, flexible and real-time redundancy concept to fulfill the availability requirements of SS7: Reliable Server Pooling (RSe...

background: luxi is a component of the quorum sensing signaling pathway in vibrio fischeri responsible for the inducer synthesis that is essential for bioluminescence. methods: homology modeling of luxi was carried out using phyre2 and refined with the galaxyweb server. five models were generated and evaluated by errat, anolea, qmean6, and procheck. results: five refined models were generated b...

In order to cope with the requirements of availability-critical internet services, reliable server pooling (RSerPool) has been developed as the new IETF standard for a lightweight server redundancy and session failover framework. While the service and pool management performance of RSerPool had already been the topic of various research papers, its security has not yet been widely examined. But...

Raja Jothi and Balaji Raghavachari Department of Computer Science, University of Texas at Dallas Richardson, TX 75083, USA fraja, [email protected] Abstract—We consider the problem of placing k proxies on a n node network to support server-based reliable multicast. Typically, in a multicast connection, the sender transmits information to all the receivers in the multicast group. Failures in tra...

Heterogeneous servers which can differ in service speed and reliability are getting more popular in modelling of modern communication systems. For a two-server queueing system with one non-reliable server and constant retrial discipline we formulate an optimal allocation problem for minimizing a long-run average cost per unit of time. Using a Markov decision process formulation we prove a numbe...

MONOMI is a system for securely executing analytical workloads over sensitive data on an untrusted database server. MONOMI works by encrypting the entire database and running queries over the encrypted data. MONOMI introduces split client/server query execution, which can execute arbitrarily complex queries over encrypted data, as well as several techniques that improve performance for such wor...

The Reliable Server Pooling (RSerPool) protocol suite currently under standardization by the IETF is designed to build systems providing highly available services by providing mechanisms and protocols for establishing, configuring, accessing and monitoring pools of server resources. While availability is one main aspect of RSerPool, load distribution is another. Since most of the time a server ...

This code contribution paper provides an overview of the RSPSIM model, which is a simulation model for the Reliable Server Pooling (RSerPool) framework. RSerPool denotes an IETF standard for the management of server pools and sessions with these pools. Such mechanisms are also crucial in the context of cloud computing research.

This document describes a mobility services framework design (MSFD) for the IEEE 802.21 Media Independent Handover (MIH) protocol that addresses identified issues associated with the transport of MIH messages. The document also describes mechanisms for Mobility Services (MoS) discovery and transport-layer mechanisms for the reliable delivery of MIH messages. This document does not provide mecha...
