Israeli technology
Bosco Israel and Egypt accounted to the majority of US development aid. Most of it military related (that was during the Cold War days).
I am making the connection between the aid Israel received and its technical prowess today. Besides that, as a small country with small population Israel had to be a kind of "James Bond state". Hence the efforts to develop technology in-house.
Siemens is sucking Israeli technology a lot. RADNET is now www.seabridgenetworks.com I wonder what more is on the store.
Siemens/Seabridge Broadband Concentrator Cuts Costs For DSLAM Providers
Patent-pending Goodput Enhancer Means Less Traffic Congestion for DSL Services
(www.seabridgenetworks.com)
[SUPERCOMM] ATLANTA, Ga., June 6, 2000 - Siemens Information and Communication Networks, Inc. and Seabridge Limited, a wholly owned subsidiary of Siemens, today announced the cost-cutting effects of its XpressGate™ Multiservice Broadband Concentrator with enhanced goodput* traffic management will be demonstrated at Supercomm. XpressGate is part of Siemens' new XpressNetTM solution. XpressNet is a highly scalable carrier-class next-generation product portfolio capable of supporting both broadband and narrowband switched services.
Both the Siemens/Seabridge XpressGate 140 (11 slots) and XpressGate 144 (5 slots) utilize the patent-pending goodput enhancer technology to boost effective throughput, or those ATM* cells which are successfully recombined at the receiver end. The Siemens/Seabridge broadband concentrator allows carriers to improve perfor-mance of multiservice networks, while increasing the number of subscribers per port, thus cutting costs, through its unique goodput enhancer (patent-pending).
Siemens/Seabridge XpressGate concentrator solves traffic congestion by:
Maximizing the number of DSL subscribers per ATM edge port
Radically enhancing network efficiency and scalability
Providing unprecedented Quality of Service and management control
Providing multiservice capabilities
Broadband access technology to the Local Loop, such as DSL, has secured its place in the telecom market as the leading infrastructure for high-speed Internet and future multimedia delivery. In current networks, the broadband provider bundles subscriber traffic toward an ILEC or CLEC central office switch.
- Typically, service specific multiplexers are used to pass the high volume of IP traffic over the ATM network toward the ISP or content provider.
IDC predicts by 2003, the total number of DSL households in the U.S. will grow from the current 330,000 to 9.3 million. Similarly, Dataquest predicts in 2003, vendors will ship 12.4 million DSL ports, compared to only 937,000 ports shipped in the first half of 1999.
Because of this projected growth, an urgent need has arisen for an intelligent broadband concentrator that can assess and manage traffic, while enforcing Quality of Service (QoS) agreements. Traditional broadband concentrators, based solely on ATM technology, are unable to process the required number of subscriber flows, therefore IP packets are discarded at the point of concentration. The congestion is further compounded as data, unable to reach its destination, is re-transmitted time and time again until it is successfully received.
The Siemens/Seabridge XpressGate multiservice broadband concentrator consolidates, filters and buffers traffic, dynamically and intelligently, using advanced algorithms, leading edge technology and system topology. The XpressGate concentrator's enhanced goodput mechanism solves data packet congestion by ensuring that no user can block the buffers of an ATM port, and traffic (ATM cells) from each user in the Virtual Path is transported over the ATM network without cell loss, or the need to re-transmit.
Maximizing the number of DSL subscribers per ATM edge port
The ATM network used to transport the DSL traffic consists mainly of edge switches spread out in Multiservice Points of Presence (MSPOP). The XpressGate broadband concentrator (used as a DSLAM concentrator) works in one geographical location, grooming access traffic into a single network trunk. By taking advantage of the fact that the trunk is not fully utilized, it can reduce the number of transport links, bridge the gap between DSLAM and ATM edge switch and thereby maximize the number of DSL subscribers per ATM port.
Radically Enhanced Network Efficiency and Scalability
Grouping multiple Virtual Channels into a single Virtual Path at the DSLAM provides scalability, while reducing operational tasks and technical bottlenecks. With the unique goodput enhancer, Siemens/Seabridge XpressGate multiservice broadband concentrator boosts the throughput of an over-subscribed and over-utilized Virtual Path containing frame-based IP and Internet traffic.
For example, XpressGate systems can be located strategically on a residential network that uses xDSL to help extend its effective bandwidth. The inherently asymmetrical nature of Internet access poses no problem for the XpressGate system's nodes, which can easily handle the extreme traffic fluctuations associated with these services. The service provider can remotely configure, manage and upgrade these facilities.
Over time, service providers can exploit the versatility of the DSLAM concentrator to offer a full range of value-added broadband services in residential, SOHO and small, medium and large enterprise customers.
Quality of Service
The XpressGate broadband concentrator features Connection Admission Control overbooking and leading-edge traffic management mechanisms, including the goodput enhancer. This functionality not only substantially increases the number of subscribers allocated to the ATM ports, but also provides sophisticated and unprecedented QoS for each subscriber.
Dynamic Multiservice and Switching Capabilities
The Siemens/Seabridge XpressGate broadband concentrator is comprised of either 11 card slots or 5 card slots, with up to 22 OC3, 33 T3 or 88 T1 network interfaces, in any combination. The platform supports multiple services, including voice, IP, frame relay and LAN and provides a switching capability of up to two gigabit/s. In addition, these carrier-class platforms offer such features as hot-swapping of service cards, redundant protection of critical components, and advanced OAM capabilities. The Siemens/Sea-bridge XpressGate broadband concentrator is managed by one of the most powerful network management systems available today, providing point-and-click, end-to-end connection management.
