Swimming Upstream -- The Case for Higher Speeds by Ikanos Communications Business and residential subscribers are constantly demanding more bandwidth. With the Internet, where a wealth of content resides on the World Wide Web, most of this demand has historically been in the downstream direction. And that will certainly continue. But what has changed is that users are now accumulating and generating copious amounts of content of their own. Users, carriers and equipment vendors alike have a long history of underestimating the need for speed. The root cause is innocent enough: keeping costs under control. But the inevitable "forklift" upgrades are disruptive and costly,which is quite ironic considering the original impetus involved cost savings. The leading technology for delivering higher bi-directional bandwidth is Very-high-bit-rate Digital Subscriber Line (VDSL). VDSL was designed to take full advantage of a carrier’s broadband infrastructure with its increasing fiber optic capacity to the node, curb or building/basement. And unlike other technologies, VDSL has the ability to deliver 100 Mbps symmetrical broadband bandwidth, which puts carrier services on par with LAN switching to the desktop. Significantly, no mass-market local loop technology has ever done that before.   View PDF   IMS Reconciliation White Paper by MultiService Forum Widespread acceptance of the principles in the 3GPP IP Multimedia Subsystem (IMS) are nearing a level that would indicate the communications industry is close to reaching a defacto convergence architecture. This whitepaper identifies similarities and differences between the MSF R2 (physical) Architecture and the 3GPP R6 Core IMS functional architecture.  It then recommends work activity the MSF should consider to achieve alignment. View PDF From Host-Remote to Next-Generation by Metaswitch Traditional telephone switching systems support the concept of "host-remote" operation, whereby lines are terminated by equipment in remote locations that is under the control of a host switch -- but potentially with the ability to operate independently of that switch if the control link is cut.  With the emergence of next generation networks, a distributed "softswitch" architecture offers the same ability to reliably deliver services across a wide geographic area with several improvements over the previous generation of equipment.  Most important of these are: multiple levels of emergency standalone operation; open interoperability; connectionless trunking in a packet network; distributed PSTN connectivity; and host site redundancy. View PDF  FTTx:  Selecting the Best Architecture for the Access Network by Occam Networks As telecommunications providers consider the best method for delivering fiber to their subscribers, they have a variety of FTTx architectures to consider. No one-size-solves-all architecture exists today, so providers must make a series of technology decisions based on their service goals. One primary consideration for providers is whether to deploy an active (point-to-point) or passive (point-to-multipoint) fiber network.. View PDF Scale network processors to 40 Gbps and beyond by Bay Microsystems, Inc.
