  • Signaling system No.7 Local Exchange deployment : Common channel signaling
    1992
    Co-Authors: G. K. Cambron
    Abstract:

    This paper examines the deployment of Signaling System No. 7 (SS7) from the viewpoint of the Local Exchange Carrier. The three phases of Local Exchange deployment, service planning and design, Local Exchange network design, and interconnection design are discussed in sequence. SS7 is a fundamental change to the infrastructure of the Local Exchange telecommunications network. It advances the efficiency, service the forces driving SS7 deployment, both services infrastructure improvements

  • Signaling System No.7 Local Exchange deployment
    Proceedings of the IEEE, 1992
    Co-Authors: G. K. Cambron
    Abstract:

    The author examines the deployment of Signaling System No.7 (SS7) from the viewpoint of the Local Exchange Carrier. The three phases of Local Exchange deployment-service planning and design, Local Exchange network design, and interconnection design-are discussed in sequence. SS7 is a fundamental change to the infrastructure of the Local Exchange telecommunications network. The author describes how the backbone network, centered on the signaling transfer points (STPs), is installed first, followed by the Local Exchange network, and then interconnection to interchange and other networks. >

  • LCN - Building cost effective lower layer VPNs: The ILEC/CLEC paradox
    2009 IEEE 34th Conference on Local Computer Networks, 2009
    Co-Authors: Aref Meddeb, Abdelwahed Berguiga, Habib Youssef
    Abstract:

    Layer 2 and layer 1 VPN services, ranging from simple leased lines to extending private LANs, are commonplace today. With the continuously growing economic difficulties, capital meltdown and telecommunication business turmoil, delivering those VPN services at the lowest cost or with the maximum revenue margin, while committing to Service Level Agreements (SLA), has become essential. We show that whether we tackle the VPN design problem from an Incumbent Local Exchange Carrier (ILEC) standpoint or from a Competitive Local Exchange Carrier (CLEC) standpoint, we obtain contradictory rules. We show that by building Edge Disjoint VPN trees and splitting the traffic among them, the ILEC can achieve maximum throughput, revenue, and better network performance. On the other hand, by concentrating all the VPN traffic over a single tree, the CLEC can minimize the cost of leased bandwidth while meeting minimum SLA targets. We then propose two simple algorithms that can help Carriers and service provides, respectively, leverage their networks and increase their revenue margins while committing to tight SLAs with their customers.

  • ISCC - Optimal VPN design: The ILEC/CLEC dilemma
    2009 IEEE Symposium on Computers and Communications, 2009
    Co-Authors: Aref Meddeb, Abdelwahed Berguiga, Habib Youssef
    Abstract:

    Layer 2 and layer 1 VPN services, ranging from simple leased lines to extending private LANs, are commonplace today.

  • Building cost effective lower layer VPNs: The ILEC/CLEC dilemma
    International Journal of Communication Systems, 2010
    Co-Authors: Aref Meddeb
    Abstract:

    Layer 2 and layer 1 Virtual Private Network (VPN) services; ranging from simple leased lines to extending private LANs across public networks, are commonplace today. With the continuously growing economic difficulties, capital meltdown, and telecommunication business turmoil, delivering those VPN services at the lowest cost or with the maximum revenue margin, while committing to Service Level Agreements (SLA), has become essential. We show that whether we tackle the optimal VPN design problem from an Incumbent Local Exchange Carrier (ILEC) standpoint or from a Competitive Local Exchange Carrier (CLEC) standpoint, we obtain contradictory rules. We show that by building Edge Disjoint VPN trees and spreading the traffic all over the network, the ILEC can achieve maximum throughput and enhanced network performance; while by concentrating all the VPN traffic over a single tree, the CLEC can minimize the cost of leased bandwidth. We then propose two simple algorithms that can help Carriers and service providers leverage their networks and increase their revenue margins while meeting SLA requirements.

  • Optimal Local Exchange Carrier Size
    Review of Industrial Organization, 1998
    Co-Authors: Sumit K. Majumdar, Hsi-hui Chang
    Abstract:

    Optimal firm size and patterns of returns to scaleamong the Local Exchange companies in the U.S.telecommunications industry are estimated for theyears: 1975, 1978, 1981, 1984, 1987 and 1990. Theindependent companies display increasing returns toscale, while the Baby Bells display constant ordecreasing returns to scale. The independentcompanies operate at a scale smaller than optimalsize, while the Baby Bells operate at a scale greaterthan optimal size. Efficiencies can be gained byindustry restructuring, by allowing independents toexpand their size while the Baby Bells can bedownsized to create smaller units.
