Core router

A core router is a router designed to operate in the Internet backbone, or core. To fulfill this role, a router must be able to support multiple telecommunications interfaces of the highest speed in use in the core Internet and must be able to forward IP packets at full speed on all of them. It must also support the routing protocols being used in the core. A core route is distinct from an edge router: edge routers sit at the edge of a backbone network and connect to core routers.

Like the term "supercomputer", the term "core router" refers to the largest and most capable routers of the then-current generation. A router that was a core router when introduced will not be a core router ten years later. At the inception of the ARPANET (the Internet's predecessor) in 1969, the fastest links were 56 kbit/s and a given routing node had at most six links. The "core router" was a dedicated minicomputer called an IMP Interface Message Processor.[1][2][3] Link speeds increased steadily, requiring progressively more powerful routers until the mid-1990s, when the typical core link speed reached 155 Mbit/s. At that time, several breakthroughs in fiber optic telecommunications (notably DWDM and EDFA technologies) combined to permit a sudden dramatic increase in core link speeds: by 2000, a core link operated at 2.5 Gbit/s and core internet companies were planning for 10 Gbit/s speeds.

The largest provider of core routers in the 1980s and 1990s was Cisco Systems, who provided core routers as part of a broad product line. This was despite the presence of faster and more capable routers from Wellfleet Communications, which existed as an independent company until it merged with SynOptics Communications in 1994, to become Bay Networks. Juniper Networks entered the business in 1996, focusing primarily on core routers. Both companies addressed the need for a radical increase in routing capability that was driven by the increased link speed. In addition, several new companies attempted to develop new core routers in the late 1990s. It was during this period that the term "core router" came into wide use. The required forwarding rate of these routers became so high that it could not be met with a single processor or a single memory, so these systems all employed some form of a distributed architecture based on an internal switching fabric.

The Internet was historically supply-limited, and core Internet providers historically struggled to expand the Internet to meet the demand. During the late 1990s, they expected a radical increase in demand, driven by the Dot-com bubble. By 2001, it became apparent that the sudden expansion in core link capacity had outstripped the actual demand for internet services in the core. The core internet providers were able to defer purchases of new core routers for a time, and most of the new companies went out of business. Cisco and Juniper were able to deliver their newest core router products several years later.

As of 2007, the internet core link speed is 10 Gbit/s, with a few links at 40 Gbit/s. Cisco's core router is the CRS-1 and Juniper's core routers comprise the T-series.

Server Rack



A rack server, also called a rack-mounted server, is a computer dedicated to use as a server and designed to be installed in a framework called a rack. The rack contains multiple mounting slots called bays, each designed to hold a hardware unit secured in place with screws. A rack server has a low-profile enclosure, in contrast to a tower server, which is built into an upright, standalone cabinet.

A single rack can contain multiple servers stacked one above the other, consolidating network resources and minimizing the required floor space. The rack server configuration also simplifies cabling among network components. In an equipment rack filled with servers, a special cooling system is necessary to prevent excessive heat buildup that would otherwise occur when many power-dissipating components are confined in a small space.

ZYPAD



he Zypad WL 1000 is based on a Raza Microelectronics 32-bit MIPS-based AU 1100 processor (formerly offered by AMD) clocked at 400MHz. It has 64MB each of flash RAM and flash ROM, with expansion available through an SD card slot.

The Zypad WL 1000 has a 3.5-inch QVGA (240 x 320) touchscreen with automatic contrast adjust. It also features an 11-key backlit keypad.

Network interfaces include 802.11b/g, GPS, and PAN Bluetooth class 2 (32 feet), each with integral antennas. The device also includes USB 1.1 host and device ports, along with stereo audio I/O.

The Zypad WL 1000 comes with a 2200 mAh 3.6 V Li-ion removable battery pack claimed to offer up to eight hours of life, depending on usage. An external power supply and car adapter will be available separately.

Additional touted features include:

* Comfortable weight distribution, even over clothing
* Tilt and dead reckoning system -- can determine if a user is motionless or has fallen down, and initiate radiosonde beacon
* Patent-applied-for switch initiates standby mode when users arm hangs down beside the body
* Claimed battery life up to 8 hours

Mike Southworth, marketing director, said Pavus is optimistic about the marketplace prospects for the unique wrist-worn PC. "The WL 1000 is a great platform for systems integrators and OEMs to build products on. The types of projects expressing interest in the defense space include healthcare systems that provide treatment information and patient history to field paramedics. There's a Navy program that calls for such devices in the thousands of units."

Availability

The Zypad WL 1000 is being manufactured by Eurotech in Italy, according to Southworth. Parvus currently has demo units, and expects to have the product "on the shelf" in late July, priced at $2,500.

Eurotech's Wrist-worn PC roadmap also calls for an ARM-based model by year's end, Southworth said.

The Zypad WL 1000 is being demonstrated at the Armed Forces Communication Electronics Association's 2006 TechNet International Conference held today in Washington D.C.
