Telecom Convergence and Moore’s LawIt will come as no surprise to PC users that processing performance has come to a plateau for a few years now. Furthermore, it should also not come as a surprise, as least to those not in denial, that a similar geographical feature has developed in telecom. Concerns about future router evolution, in particular, were voiced by service providers as recently as the recent SUPERCOMM 2009 show. |

The Video TrianglesVideo-based electronic content was identified in the last instance of this blog as the primary driver behind bandwidth considerations in a convergent network. However, bandwidth is only one of the many dimensions of the electronic video transport conundrum. For purposes of discussion, let’s assume that electronic video distribution can broken down into various planes represented by ... |

Bandwidth Crunch BeginsPrevious instances of this blog discussed the various services that will have to be addressed by the ongoing telecommunication convergence. In particular, the bandwidth needs of tele-entertainment services, HD tele-conferencing and cloud computing, just to name a few, were pointed out.Since “to want” and “to get” are unfortunately usually two different things, the question ... |

Perfect Convergence Technology Remains ElusiveDespite their advantages, at least for some services, thorny issues, primarily related to hard-QoS, reliability and network synchronization still hover over both Ethernet and yet another network-convergence candidate: Internet Protocol over Multi-Protocol Label Switching (IP/MPLS).Some of these applications, such as conversational communications, thrived throughout the last century, but may ... |

DPI … Anyone?Deep Packet Inspection (DPI) usually defines a set of technologies that reach beyond the header of a packet to also examine the attached payload. Among other reasons, the need for this networking practice has often been justified as to help ensure that various QoS parameters can be managed by NSPs. As a possible component of a future convergent network, a brief discussion of the top reasons ... |
