An adaptive label propagation algorithm (ALPA) is proposed to detect and monitor communities in dynamic networks. Unlike the traditional methods by re-computing the whole community decomposition after each modification of the network, ALPA takes into account the information of historical communities and updates its solution according to the network modifications via a local label propagation pr...

Optical networking poses a number challenges for Generalized MultiProtocol Label Switching (GMPLS). Fundamentally, optical technology is an analog rather than digital technology whereby the optical layer is lowest in the transport hierarchy and hence has an intimate relationship with the physical geography of the network. This contribution surveys some of the aspects of optical networks that im...

Multi-Topology (MT) routing is supported in IP networks with the use of MT-aware IGPs. In order to provide MT routing within Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) networks, new extensions are required. This document describes the LDP protocol extensions required to support MT routing in an MPLS environment. Information about the current status of this document, ...

Humans process visual scenes selectively and sequentially using attention. Central to models of human visual attention is the saliency map. We propose a hierarchical visual architecture that operates on a saliency map and uses a novel attention mechanism to sequentially focus on salient regions and take additional glimpses within those regions. The architecture is motivated by human visual atte...

The first global interoperability experiment of GMPLS controlled Ethernet with VLAN tag swapping between two different implementations is successfully demonstrated. High definition video streaming is realized through a newly established Layer 2 Label Switched Path (L2LSP). The results of this experiment can be applied to designing reliable Layer 2 networks. key words: VLAN tag swapping, Etherne...

ITU-T recommendation G.709-2012 has introduced new fixed and flexible Optical channel Data Unit (ODU) containers in Optical Transport Networks (OTNs). This document provides an evaluation of existing Generalized Multiprotocol Label Switching (GMPLS) routing and signaling protocols against the G.709 OTNs.

In this paper, we tackle the challenges of multilabel classification by developing a general conditional dependency network model. The proposed model is a cyclic directed graphical model, which provides an intuitive representation for the dependencies among multiple label variables, and a well integrated framework for efficient model training using binary classifiers and label predictions using...

Assigning several labels to digital data is becoming easier because we can perform it in a collaborative manner with Internet users. However, some suitable labels may be missed and may not be attached to the data leading to inaccuracies in classification. In this paper, we propose a novel graphbased multi-label classifier to support the multi-labeling task. The core process of our algorithm is ...

In the recent past, Network Virtualization (NV) received much attention. Nevertheless, Virtual Networks (VNs) are still not available on the market. The consortium of the COntrol and Management of COexisting Networks (COMCON) project examines the potential interactions in vertically and horizontally divided markets and evaluates the applicability of existing technologies, like Generalized Multi...
