“…In unstructured P2P networks, there is no relationship between any one node and any distributed network resource. Retrieving any network resource generally involves random walks and/or flooding approaches, which are inefficient and do not guarantee the discovery of a resource [18]. This is addressed in structured P2P systems, which provide efficient search strategies that guarantee content location within a small number of hops.…”

“…Systems who support such an approach arrange these peers in various topologies to help limit the number of routing messages exchanged to access the resource. Some protocols generate a ring structure, as in Chord [17] [21], others generate a mesh, as seen in Pastry [18] [22]. For all these structured P2P overlays, the established logical topologies need to be maintained as the P2P system experiences churn (peers joining and leaving), resulting in a potentially significant amount of maintenance traffic.…”

We explored how to deploy P2P overlays in ultimately large-scale Mobile Ad-Hoc Networks (MANETs). We therefore studied the performance of P2P overlays such as Chord, creating a number of flat and hierarchical MANET networks. The hierarchical network consists of clusters, interconnected by a backbone. The subnetworks (cluster or the whole network) ran OLSR as network-layer routing protocol. Each cluster had a gateway, interconnected through a backbone that deployed flooding. As we increased the number of clusters, we kept the number of nodes in the Chord overlay constant. Using simulations in OMNeT++, we evaluated the P2P performance. Our results show that an unmodified P2P network does not perform well even for relatively small network sizes. The performance can be improved through the use of a cross-layered P2P solution, such as OneHopOverlay4MANET. However, such cross-layered approaches require complete information about overlay nodes from the routing layer and are therefore not suitable in hierarchical MANETs. For hierarchical underlays, the performance of the P2P overlay deteriorated as we increased the number of clusters. One of the main reasons is that the backbone quickly became a performance bottleneck.

A multilevel taxonomy and requirements for an optimal traffic‐classification model

2014

Identifying Internet traffic applications is essential for network security and management. The steady emergence of new Internet applications, together with the use of encryption and obfuscation techniques, ensures that traffic classification remains a hot research topic. Much research has been devoted to this topic by the research community in the last decade. However, an optimal traffic classification model has yet to be defined. Many techniques and formats have been described, with the current literature therefore lacking appropriate benchmarks expressed in a consistent terminology. Moreover, existing surveys are outdated and do not include many recent advances in the field. In this article, we present a systematic multilevel taxonomy that covers a broad range of existing and recently proposed methods, together with examples of vendor classification techniques. Our taxonomy assists in defining a consistent terminology. It could be useful in future benchmarking contexts by characterizing and comparing methods at three different levels. From this perspective, we describe key features and provide design hints for future classification models, while emphasizing the main requirements for promoting future research efforts. To motivate researchers and other interested parties, we collect and share data captured from real traffic, using two models to protect data privacy.
