Multiprotocol Label Switching [PDF]
Advances in Electrical and Electronic Engineering, 2007 The up to this time known networks with the IP protocol have worked as connection-less and they have not guaranteed the quality of services. Implementing the MPLS protocol, an overlay connection-oriented network with guaranteed quality of services QoS ...

Bayesian solutions to the label switching problem [PDF]
, 2008 The label switching problem, the unidentifiability of the permutation of clusters or more generally latent variables, makes interpretation of results computed with MCMC sampling difficult. We introduce a fully Bayesian treatment of the permutations which

Label Switching in Mixtures [PDF]
AIP Conference Proceedings, 2011 We propose a posterior distribution for which the latent partition is restricted to a special numbering leading to the largest separation with its permutations. Two different measures of separation are proposed, the first one being global but intractable even from very small sample sizes (Kullback divergence), the second one being local and thus very ...

Bayesian mixture labeling and clustering [PDF]
, 2012 Label switching is one of the fundamental issues for Bayesian mixture modeling. It occurs due to the nonidentifiability of the components under symmetric priors. Without solving the label switching, the ergodic averages of component specific quantities

Effects of crosstalk in WDM optical label switching networks due to wavelength switching of a tunable laser [PDF]
, 2006 rosstalk caused by switching events in fast tunable lasers in an optical label switching (OLS) system is investigated for the first time. A wavelength-division-multiplexed OLS system based on subcarrier multiplexed labels is presented which employs a 40 ...

Overfitting Bayesian Mixture Models with an Unknown Number of Components [PDF]
, 2015 This paper proposes solutions to three issues pertaining to the estimation of finite mixture models with an unknown number of components: the non-identifiability induced by overfitting the number of components, the mixing limitations of standard Markov ...

Optimizing segment routing using evolutionary computation [PDF]
, 2017 Segment Routing (SR) combines the simplicity of Link-State routing protocols with the flexibility of Multiprotocol Label Switching (MPLS). By decomposing forwarding paths into segments, identified by labels, SR improves Traffic Engineering (TE) and ...

SCM optical label switching scheme in a WDM packet transmitter employing a switching SG-DBR laser [PDF]
, 2006 We demonstrate an SCM optical label switching scheme with spectral efficiency of 0.4bit/s/Hz and a spectral density figure of merit of 1. We then employ this scheme in a WDM transmitter subsystem and we investigate the detrimental effects that switching ...
