Amsterdam Internet Exchange
The Amsterdam Internet Exchange (AMS-IX) is an Internet exchange point based in Amsterdam, in the Netherlands. Established in the early 1990s, AMS-IX is a non-profit, neutral and independent peering point. History In February 1994, a layer 2 shared infrastructure, used between academic institutes, was connected with CERN to exchange traffic. Other Internet service providers were allowed to connect and the name AMS-IX was first used. In 1997, the AMS-IX Association was founded by twenty of the connected Internet service providers and carriers. In 2002, the Neutral Internet Exchange was founded as an alternative or backup for the Amsterdam Internet Exchange. , AMS-IX connected 396 members on 684 ports. The all-time peak of incoming traffic was 1.513 Tbit/s and of outgoing traffic 1.512 Tbit/s compared to 0.833 Tbit/s average incoming and outgoing, in January 2012. In November 2016, AMS-IX broke through the 5 Tbit/s ceiling. The total amount of data transferred by month was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slotervaart (former Borough)
Slotervaart is a former district of Amsterdam, Netherlands. It had a population of 48,540 inhabitants in 2008 and an area of 11.14 km². As of 2010, Slotervaart is part of the newly formed ''stadsdeel'' Nieuw-West. Slotervaart has a significant immigrant population; 33% of the inhabitants are from Morocco, 21% are from Turkey, and 5% are from Suriname. In 2007, Slotervaart youngsters burned cars and threw stones at the police after a stabbing accident at the Allebeplein, where the police killed a Moroccan boy. At the edge of Slotervaart is the Sloterpark, a recreational location popular among young families with children, and also among men who have sex with men for whom the park is a famous cruising spot. The different clienteles traditionally frequent separate areas of the large park. Sometimes, homosexual tourists (who visit Slotervaart for its famous park) have not been aware of this distinction, and this has led to incidents of gay bashing. In early 2009 signs were ...

Wavelength-division Multiplexing
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over a single strand of fiber, also called wavelength-division duplexing, as well as multiplication of capacity. The term WDM is commonly applied to an optical carrier, which is typically described by its wavelength, whereas frequency-division multiplexing typically applies to a radio carrier which is more often described by frequency. This is purely conventional because wavelength and frequency communicate the same information. Specifically, frequency (in Hertz, which is cycles per second) multiplied by wavelength (the physical length of one cycle) equals the velocity of the carrier wave. In a vacuum, this is the speed of light, usually denoted by the lowercase letter, c. In glass fiber, it is subst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Network Switch
A network switch (also called switching hub, bridging hub, and, by the IEEE, MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches. Switches for Ethernet are the most common form of network switch. The first MAC Bridge was invented in 1983 by Mark Kempf, an engineer in the Networking Advanced Development group of Digital Equipment Corporation. The first 2 port Bridge product (LANBridge 100) was introduced by that company shortly after. The company subsequently produced multi-port switches for both Ethernet and FDDI such as GigaSwitch.

Link Aggregation
In computer networking, link aggregation is the combining ( aggregating) of multiple network connections in parallel by any of several methods, in order to increase throughput beyond what a single connection could sustain, to provide redundancy in case one of the links should fail, or both. A link aggregation group (LAG) is the combined collection of physical ports. Other umbrella terms used to describe the concept include trunking, bundling, bonding, channeling or teaming. Implementation may follow vendor-independent standards such as Link Aggregation Control Protocol (LACP) for Ethernet, defined in IEEE 802.1AX or the previous IEEE 802.3ad, but also proprietary protocols. Motivation Link aggregation increases the bandwidth and resilience of Ethernet connections. Bandwidth requirements do not scale linearly. Ethernet bandwidths historically have increased tenfold each generation: 10 megabit/s, 100 Mbit/s, 1000 Mbit/s, 10,000 Mbit/s. If one started to bump in ...

10 Gigabit Ethernet
10 Gigabit Ethernet (10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Unlike previous Ethernet standards, 10 Gigabit Ethernet defines only full-duplex point-to-point links which are generally connected by network switches; shared-medium CSMA/CD operation has not been carried over from the previous generations Ethernet standards so half-duplex operation and repeater hubs do not exist in 10GbE. The 10 Gigabit Ethernet standard encompasses a number of different physical layer (PHY) standards. A networking device, such as a switch or a network interface controller may have different PHY types through pluggable PHY modules, such as those based on SFP+. Like previous versions of Ethernet, 10GbE can use either copper or fiber cabling. Maximum distance over copper cable is 100 meters but because of its bandwidth requirements, higher ...

Gigabit Ethernet
In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the term applied to transmitting Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T, is defined by the IEEE 802.3ab standard. It came into use in 1999, and has replaced Fast Ethernet in wired local networks due to its considerable speed improvement over Fast Ethernet, as well as its use of cables and equipment that are widely available, economical, and similar to previous standards. History Ethernet was the result of research conducted at Xerox PARC in the early 1970s, and later evolved into a widely implemented physical and link layer protocol. Fast Ethernet increased the speed from 10 to 100 megabits per second (Mbit/s). Gigabit Ethernet was the next iteration, increasing the speed to 1000 Mbit/s. * The initial standard for Gigabit Ethernet was produced by the IEEE in June 1998 as IEEE 802.3z, and required optical fiber. 802.3z is commonly referred to as 1000BASE-X, whe ...

Virtual Switch Redundancy Protocol
The Virtual Switch Redundancy Protocol (VSRP) is a proprietary network resilience protocol developed by Foundry Networks and currently being sold in products manufactured by both Brocade Communications Systems (formerly Foundry Networks) and Hewlett Packard. The protocol differs from many others in use as it combines Layer 2 and Layer 3 resilience – effectively doing the jobs of both Spanning tree protocol and the Virtual Router Redundancy Protocol at the same time. Whilst the restrictions on the physical topologies able to make use of VSRP mean that it is less flexible than STP and VRRP, it does significantly improve on the failover times provided by either of those protocols.
