Consortium
A consortium () is an association of two or more individuals, companies, organizations, or governments (or any combination of these entities) with the objective of participating in a common activity or pooling their resources for achieving a common goal. Consortia are generally nonprofit with a goal to help its members improve their competitiveness in the specific field. is a Latin word meaning " partnership", "association", or "society", and derives from ("shared in property"), itself from ("together") and ("fate"). Examples Educational The Universities' consortium is established to share research laboratories and equipment facilities, exchange faculty and students, provide programs abroad, and form specialized research centers and admissions offices.Wallace Lang D (1975).

Optical Fiber
An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other. Such fibers find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher Bandwidth (computing), bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less Attenuation, loss and are immune to electromagnetic interference. Fibers are also used for illumination (lighting), illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, such as fiber optic sensors and fiber lasers. Glass optical fibers are typically made by Drawing (manufacturing), drawing, while plastic fibers can be made either by drawing or by extrusion. Optical fibers typically incl ...

LTE (telecommunication)
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for cellular mobile devices and data terminals. It is considered to be a "transitional" 4G technology, and is therefore also referred to as 3.95G as a step above 3G. LTE is based on the 2G GSM/ EDGE and 3G UMTS/ HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. LTE has been succeeded by LTE Advanced, which is officially defined as a "true" 4G technology and also named "LTE+". Terminology The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is also called 3.95G and has been marketed as 4G LTE and Advanced 4G; but the original version did not meet the technical criteria of a 4G wire ...

XDSL
Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access. In ADSL, the data throughput in the upstream direction (the direction to the service provider) is lower, hence the designation of ''asymmetric'' service. In symmetric digital subscriber line (SDSL) services, the downstream and upstream data rates are equal. DSL service can be delivered simultaneously with wired telephone service on the same telephone line since DSL uses higher frequency bands for data transmission. On the customer premises, a DSL filter is installed on each telephone to prevent undesirable interaction between DSL and telephone service. The bit rate of consumer ADSL services typically ranges from up to , while the later VDSL+ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Access Networks
Hybrid Access Networks refer to a special architecture for broadband access networks where two different network technologies are combined to improve bandwidth. A frequent motivation for such Hybrid Access Networks to combine one xDSL network with a wireless network such as LTE. The technology is generic and can be applied to combine different types of access networks such as DOCSIS, WiMAX, 5G or satellite networks. The Broadband Forum has specified an architecture as a framework for the deployment of such converged networks. Use cases One of the main motivations for such Hybrid Access Networks is to provide faster Internet services in rural areas where it is not always cost-effective to deploy faster xDSL technologies such as G.Fast or VDSL2 that cannot cover long distances between the street cabinet and the home. Several governments, notably in Europe, required network operators to provide fast Internet services to all inhabitants with a minimum of 30 Mbps by 2020. A second use ...

TR-196
TR-196 (Technical Report 196) is a Broadband Forum technical specification. Its official title is "Femto Access Point Service Data Model." The purpose of this Technical Report is to specify the Data Model for the Femtocell, Femto Access Point (FAP) for remote management purposes using the TR-069 CWMP. FAP is a generic terminology that implies any Radio access technology, Radio Access Technology (RAT). In 3GPP's terminology, Home Node B is the name for 3G (UMTS) and Home eNode B for LTE (telecommunication), LTE. Details There are two major releases ("Issue" in BBF terminology) of TR-196 data model. Issue 1 is the first publication which supports UMTS Home Node B, HNB only. It was later expanded to include LTE Home eNode B, HeNB and CDMA2000 FAP, and was released as Issue 2. {, class="wikitable" style="text-align:center; font-size:96%;" , - !width=75, TR-196 Release!!width=75, 3GPP Release alignment!!width=75, UMTS!!width=75, LTE (telecommunication), LTE!!width=75, CDMA2000 , - , ...

Femtocell
In telecommunications, a femtocell is a small, low-power cellular base station, typically designed for use in a home or small business. A broader term which is more widespread in the industry is ''small cell'', with ''femtocell'' as a subset. It typically connects to the service provider's network via the Internet through a wired broadband link (such as digital subscriber line, DSL or cable television, cable); current designs typically support four to eight simultaneously active mobile phones in a residential setting depending on version number and femtocell hardware, and eight to sixteen mobile phones in enterprise settings. A femtocell allows service providers to extend service coverage indoors or at the cell edge, especially where access would otherwise be limited or unavailable. Although much attention is focused on W-CDMA, WCDMA, the concept is applicable to all standards, including GSM, CDMA2000, TD-SCDMA, WiMAX and LTE (telecommunication), LTE solutions. The use of femtoce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATM Forum
The ATM Forum was a non-profit industry consortium founded in 1991 to promote Asynchronous Transfer Mode technology. The founding president and chairman was Fred Sammartino of Sun Microsystems. The ATM Forum created over 200 implementation agreements. History In 1996 ATM technology stabilized with the "Anchorage Accord", which established the baseline of ATM implementations. While ATM did not live up to every expectation, it remained an important core network technology. The Frame Relay Forum (promoting Frame Relay) also started in 1991. The MPLS Forum (which supported Multiprotocol Label Switching had begun in 2000. Those two merged in 2003 to become the MPLS and Frame Relay Alliance (MFA). In 2005, the ATM Forum joined forces with the MFA to form the MFA Forum, which was renamed to be the IP/MPLS Forum. In May 2009 the IP/MPLS Forum merged with the Broadband Forum.

Multiprotocol Label Switching
Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on labels rather than network addresses. Whereas network addresses identify endpoints, the labels identify established paths between endpoints. MPLS can encapsulate packets of various network protocols, hence the ''multiprotocol'' component of the name. MPLS supports a range of access technologies, including T1/ E1, ATM, Frame Relay, and DSL. Role and functioning In an MPLS network, labels are assigned to data packets. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. This allows one to create end-to-end circuits across any type of transport medium, using any protocol. The primary benefit is to eliminate dependence on a particular OSI model data link layer (layer 2) technology, and eliminate the need for multiple layer-2 networks to satisfy different types of tra ...

DSLAM
A digital subscriber line access multiplexer (DSLAM, often pronounced ''DEE-slam'') is a network device, often located in telephone exchanges, that connects multiple customer digital subscriber line (DSL) interfaces to a high-speed digital communications channel using multiplexing techniques. Its cable internet (DOCSIS) counterpart is the cable modem termination system. Path taken by data to DSLAM # Customer premises: DSL modem terminating the Asymmetric digital subscriber line, ADSL, Single-pair high-speed digital subscriber line, SHDSL or VDSL circuit and providing a LAN or interface to a single computer or LAN segment. # Local loop: the telephone company wires from a customer to the telephone exchange or to a serving area interface, often called the "Last mile (telecommunications), last mile" (LM). # Telephone exchange: #* Main distribution frame (MDF): a wiring rack that connects outside subscriber lines with internal lines.

Ethernet
Ethernet ( ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses a thick coaxial cable as a shared medium. This was largely superseded by 10BASE2, which used a thinner and more flexible cable that was both less expensive and easier to use. More modern Ethernet variants use Ethernet over twisted pair, twisted pair and fiber optic links in conjunction with Network switch, switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the lates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Attached Storage
Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. In this context, the term "NAS" can refer to both the technology and systems involved, or a specialized computer appliance device unit built for such functionality – a ''NAS appliance'' or ''NAS box''. NAS contrasts with block-level storage area networks (SAN). Overview A NAS device is optimised for serving files either by its hardware, software, or configuration. It is often manufactured as a computer appliance a purpose-built specialized computer. NAS systems are networked appliances that contain one or more storage drives, often arranged into logical, redundant storage containers or RAID. Network-attached storage typically provide access to files using network file sharing protocols such as NFS, SMB, or AFP. From the mid-1990s, NAS devices began gaining popularity as a convenient method of sharing fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
