Autonomic cache management in Information-Centric Networks
Sourlas, V.; Flegkas, P.; Gkatzikis, L.; Tassiulas, L. (2012)Recent research efforts in the area of future networks indicate Information-Centric Networking (ICN) as the dominant architecture for the Future Internet. The main promise of ICN is that of shifting the communication ... -
Cache-aware routing in Information-Centric Networks
Sourlas, V.; Flegkas, P.; Tassiulas, L. (2013)Information-Centric Networking (ICN) has attracted the attention of the research community, which has argued that content, instead of end-points, must be at the center stage of attention. The research issues addressed by ... -
Caching in content-based publish/subscribe systems
Sourlas, V.; Paschos, G. S.; Flegkas, P.; Tassiulas, L. (2009)In a publish/subscribe network, message delivery is guaranteed for all active subscribers at publish time. However, in a dynamic scenario where users join and leave the network, a user may be interested in content published ... -
A cloud-based content replication framework over multi-domain environments
Katsalis, K.; Sourlas, V.; Korakis, T.; Tassiulas, L. (2014)Cloud service provisioning on top of virtual infrastructures is of major importance in modern ICT, since it is directly correlated to the way business models are designed and revenue is generated from the cloud service ... -
A comparison of centralized and distributed meta-scheduling architectures for computation and communication tasks in Grid networks
Christodoulopoulos, K.; Sourlas, V.; Mpakolas, I.; Varvarigos, E. (2009)The management of Grid resources requires scheduling of both computation and communication tasks at various levels. In this study, we consider the two constituent sub-problems of Grid scheduling, namely: (i) the scheduling ... -
Content Replication and Delivery in Information-Centric Networks
Sourlas, V.; Flegkas, P.; Katsaros, D.; Tassiulas, L. (2014)Information-centric networking (ICN) is emerging as the main future networking environment, given that the vast majority of Internet activities are related to information access and delivery. This chapter presents a ... -
A content-based publish/subscribe framework for large-scale content delivery
Diallo, M.; Sourlas, V.; Flegkas, P.; Fdida, S.; Tassiulas, L. (2013)The publish/subscribe communication paradigm has become an important architectural style for designing distributed systems and has recently been considered one of the most promising future network architectures that solves ... -
Distribute, store and retrieve management policies in wireless ad-hoc networks using the content delivery publish/subscribe paradigm
Sourlas, V.; Flegkas, P.; Paschos, G. S.; Tassiulas, L. (2009)Policy management is a management paradigm that has been extensively studied for the case of fixed networks but limited work can be found for migrating it to mobile environments. It enables dynamic adaptation of the network ... -
Distributed cache management in information-centric networks
Sourlas, V.; Gkatzikis, L.; Flegkas, P.; Tassiulas, L. (2013)The main promise of current research efforts in the area of Information-Centric Networking (ICN) architectures is to optimize the dissemination of information within transient communication relationships of endpoints. ... -
Effect of somatostatinergic analogues on the ischemia-induced release of [3H]-D-aspartate and [3H]-GABA from rat retina and hippocampus
Sourlas, V.; Athanasiou, V.; Vasilaki, A. (2008)The modulation of the enhanced release of [3H]-D-Aspartate and [3H]GABA following ischemia-like conditions was studied in rat retinal and hippocampal preparations using a superfusion system. Ischemia was simulated by a ... -
Effective cache management and performance limits in information-centric networks
Sourlas, V.; Tassiulas, L. (2013)Proliferation of content distribution traffic in the Internet is changing the requirements on the networking infrastructure to the extent that radical new architectures are envisioned, where information is addressed by ... -
Leveraging caching for internet-scale content-based publish/subscribe networks
Diallo, M.; Fdida, S.; Sourlas, V.; Flegkas, P.; Tassiulas, L. (2011)This work is concerned with scaling decentralized content-based publish/subscribe (CBPS) networks for Internet-wide content distribution. A fundamental step for CBPS networks to reach the Internet-scale is to move from the ... -
Mobility support through caching in content-based publish/subscribe networks
Sourlas, V.; Paschos, G. S.; Flegkas, P.; Tassiulas, L. (2010)In a publish/subscribe (pub/sub) network, message delivery is guaranteed for all connected subscribers at publish time. However, in a dynamic mobile scenario where users join and leave the network, it is important that ... -
Mobility work re-visited not considered harmful
Trossen, D.; Vasilakos, X.; Flegkas, P.; Sourlas, V.; Parisis, G. (2011)The Internet is a universal source of information for its users. However, obtaining desired content has become the main focus of interest rather than the communication with machine endpoints. The increased availability of ... -
Modeling the dynamics of caching in content-based publish/subscribe systems
Sourlas, V.; Paschos, G. S.; Mannersalo, P.; Flegkas, P.; Tassiulas, L. (2011)This paper considers cache dimensioning in the context of publish/subscribe (pub/sub) systems. We assume that each broker is equipped with a limited capacity cache and it decides upon a policy for caching and prioritizing ... -
