    A Distributed Fault Management Scheme for Wavelength Routed All-Optical Networks (2000)
    Springer
    Photonic network communications 2 (2000), S. 369-382 
    Details
    ISSN: 1572-8188
    Schlagwort(e): all-optical networks ; fault management ; distributed algorithm ; dynamic routing
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Elektrotechnik, Elektronik, Nachrichtentechnik
    Notizen: Abstract This paper presents a distributed algorithm to determine fault avoiding routes between source-destination end-node pairs in an all-optical network. Fault-tolerant routing for WDM routed all-optical networks has not been studied in details in the literature except for using protection switching or loopback recovery. Such schemes use predetermined protection mechanism and hence assume that the protection path is not faulty. This paper considers extensions to a dynamic routing scheme (presented earlier by these authors for fault-free networks) to handle rerouting in case of fault occurrence. The performance degradations of the network because of fault occurrence are then studied in terms of blocking probability and set-up time through simulations.

    ATM Routing Algorithms for Multimedia Traffic in Private ATM Networks (2000)
    Springer
    Journal of heuristics 6 (2000), S. 21-38 
    Details
    ISSN: 1572-9397
    Schlagwort(e): ATM networks ; dynamic routing ; PNNI ; simulations ; QoS ; multimedia
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Mathematik
    Notizen: Abstract The goal of this paper is to recommend a good Private Network-to-Network Interface (PNNI) routing algorithm for private ATM networks. A good routing algorithm has to work well with multimedia traffic with several quality of service (QoS) requirements (such as cell loss ratio, cell delay and its variation etc.) in different networks under various traffic conditions. The multiplicity of QoS requirements makes the routing problem NP-complete, so our approach to the problem is based on large scale simulations involving several empirical algorithms (compliant with the PNNI routing specification) which have been tested for different network topologies and traffic scenarios. Based on analysis of tradeoffs involving performance metrics (such as blocking rate, complexity, load distribution) we recommend a consistently good routing algorithm for single domain ATM networks.

    Characterization of a novel nodulin gene in soybean that shares sequence similarity to the gene for nodulin-24 (1990)
    Springer
    Plant molecular biology 15 (1990), S. 835-849

    ISSN: 1573-5028
    Schlagwort(e): soybean ; nodulin ; gene organization ; hybrid select translation ; gene family ; developmental regulation

    Thema: Biologie
    Notizen: Abstract A gene encoding for nodulin-16 (N-16) was isolated from a soybean genomic library. Nucleotide sequence analysis of the cDNA and the genomic clone of N-16 indicated that the coding region of this gene is 330 bp long and is interrupted by a single intron of 494 bp. The coding region of the N-16 gene shows a high degree of localized sequence similarity with the coding sequence of soybean nodulin-24 (N-24). Sequence similarity between the two genes is limited to the coding region of 90 bp in the first exon and the first 54 bp in the second exon of the N-16 gene which is repeated as the 2nd, 3rd, and 4th exons in the N-24 gene. The N-24 gene has been postulated to be a result of repeated duplication of an insertion element consisting of the 54 bp exon and the flanking intron sequences. In the absence of sequence similarity in the regions flanking the 54 bp sequence between the N-16 and N-24 genes, the N-16 gene does not appear to be the ancestral gene. Both N-16 and N-24 have a similar hydrophobic amino terminal end suggesting that N-16 like N-24 is targeted to the peribacteroid membrane. Southern analysis of soybean genomic DNA shows the presence of other related sequences to the N-16 gene, one of which is found to be closely linked to it. Analysis of the temporal accumulation of the N-16 transcripts during nodule development in effective and ineffective nodules suggests that N-16 and related genes might differ from leghemoglobin and some other late nodulin genes in their mechanism of regulation.
