Routing
Routing is the process of selecting a path for traffic in a Network theory, network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. In packet switching networks, routing is the higher-level decision making that directs network packets from their source toward their destination through intermediate network nodes by specific packet forwarding mechanisms. Packet forwarding is the transit of network packets from one Network interface controller, network interface to another. Intermediate nodes are typically network hardware devices such as Router (computing), routers, gateway (telecommunications), gateways, Firewall (computing), firewalls, or network switch, switches. General-purpose computers also forward packets and perform routing, although they have no specially optimized hardware for the task. T ...

Route Of Administration
In pharmacology and toxicology, a route of administration is the way by which a medication, drug, fluid, poison, or other substance is taken into the body. Routes of administration are generally classified by the location at which the substance is applied. Common examples include oral administration, oral and intravenous therapy, intravenous administration. Routes can also be classified based on where the target of action is. Action may be topical medication, topical (local), enteral administration, enteral (system-wide effect, but delivered through the gastrointestinal tract), or #Parenteral, parenteral (systemic action, but is delivered by routes other than the GI tract). Route of administration and dosage form are aspects of drug delivery. Classification Routes of administration are usually classified by application location (or exposition). The route or course the active substance takes from application location to the location where it has its target effect is usually rat ...

Router (woodworking)
The router is a power tool with a flat base and a rotating blade extending past the base. The spindle may be driven by an electric motor or by a pneumatic motor. It routs (hollows out) an area in hard material, such as wood or plastic. Routers are used most often in woodworking, especially cabinetry. They may be handheld or affixed to router tables. Some woodworkers consider the router one of the most versatile power tools. There is also a traditional hand tool known as a router plane, a form of hand plane with a broad base and a narrow blade projecting well beyond the base plate. CNC wood routers add the advantages of computer numerical control (CNC). The laminate trimmer is a smaller, lighter version of the router. Although it is designed for trimming laminates, it can also be used for smaller general routing work. Rotary tools can also be used similarly to routers with the right bits and accessories (such as plastic router bases). History Before power routers exist ...

National Routeing Guide
The National Routeing Guide is a document, the definitive resource on the validity of rail tickets for the purpose of rail travel in Great Britain. As stated by the Rail Regulator, "''[it] sets out passengers' rights to use the network flexibly''". It is a book produced by the Rail Delivery Group, which is carried by any rail ticket inspector and is also on hand for station staff. It is one of the British railway technical manuals, technical railway manuals which exist as part of the operating of the Rail transport in Great Britain, rail network of Great Britain, many of which are now in the public domain. Customers generally encounter the document in specific circumstances, when they wish to prove (or check) the validity of their ticket on a route which might at first not appear obvious. Since most rail travellers make 'simple' journeys, many will never encounter it. However, when making more complex journeys, it is important to stay "on route". The guide defines what this mean ...

Routing (hydrology)
In hydrology, routing is a technique used to predict the changes in shape of a hydrograph as water moves through a river channel or a reservoir. In flood forecasting, hydrologists may want to know how a short burst of intense rain in an area upstream of a city will change as it reaches the city. Routing can be used to determine whether the pulse of rain reaches the city as a deluge or a trickle. Routing also can be used to predict the hydrograph shape (and thus lowland flooding potential) subsequent to multiple rainfall events in different sub-catchments of the watershed. Timing and duration of the rainfall events, as well as factors such as antecedent moisture conditions, overall watershed shape, along with subcatchment-area shapes, land slopes (topography/physiography), geology/hydrogeology (i.e. forests and aquifers can serve as giant sponges that absorb rainfall and slowly release it over subsequent weeks and months), and stream-reach lengths all play a role here.

ABA Routing Transit Number
In the United States, an ABA routing transit number (ABA RTN) is a nine-digit code printed on the bottom of cheque, checks to identify the financial institution on which it was drawn. The American Bankers Association (ABA) developed the system in 1910 to facilitate the sorting, bundling, and delivering of paper checks to the drawer's (check writer's) bank for debit to the drawer's account. Newer electronic payment methods continue to rely on ABA RTNs to identify the paying bank or other financial institution. The Federal Reserve Bank uses ABA RTNs in processing Fedwire funds transfers. The ACH Network also uses ABA RTNs in processing direct deposits, bill payments, and other automated money transfers. Management Since 1911, the American Bankers Association has partnered with a series of registrars, currently Accuity, to manage the ABA routing number system. Accuity is the Official Routing Number Registrar and is responsible for assigning ABA RTNs and managing the ABA RTN system. ...

Routing Number (Canada)
A routing number is the term for bank codes in Canada. Routing numbers consist of eight numerical digits with a dash between the fifth and sixth digit for paper financial documents encoded with magnetic ink character recognition and nine numerical digits without dashes for electronic funds transfers. Routing numbers are regulated by Payments Canada, formerly known as the Canadian Payments Association, to allow easy identification of the branch location and financial institution associated with an account. Format A routing number consists of a five digit ''transit number'' (also called ''branch number'') identifying the branch (banking), branch where an account is held and a three digit ''financial institution number'' corresponding to the financial institution. The number is given as one of the following forms, where XXXXX is the transit number and YYY is the financial institution number: * for Magnetic ink character recognition, MICR-encoded documents * for electronic funds tr ...

Weather Routing
Weather routing is a commercial service provided by commercial companies for cargo ships, to optimize their voyage performance. An adventure version of the same used for sailing boats is referred to as sailing weather prediction or sailing weather routing. The latter focusses more on the forecasting and routing of wind and currents for adventurers and competitive sailors participating in ocean sports like yacht races. For maritime commercial usage A number of large cargo ships use weather routing services for ocean passages. They are primarily geared towards protecting owners and charterers from speed claims, a secondary use being to reduce fuel consumption and improve ETAs (estimated time of arrival). Weather routing companies include; SOFAR Ocean by providing real-time data via a network of spotter buoys laid across the ocean), Blue Water Optimum Speed Services (BOSS), Ocean routes, SPOS, Storm Geo AWT(formerly Applied Weather technology), WNI and WRI. Promoters of weather routi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Routing (electronic Design Automation)
In electronic design, wire routing, commonly called simply routing, is a step in the design of printed circuit boards (PCBs) and integrated circuits (ICs). It builds on a preceding step, called placement, which determines the location of each active element of an IC or component on a PCB. After placement, the routing step adds wires needed to properly connect the placed components while obeying all design rules for the IC. Together, the placement and routing steps of IC design are known as place and route. The task of all routers is the same. They are given some pre-existing polygons consisting of pins (also called terminals) on cells, and optionally some pre-existing wiring called preroutes. Each of these polygons are associated with a net, usually by name or number. The primary task of the router is to create geometries such that all terminals assigned to the same net are connected, no terminals assigned to different nets are connected, and all design rules are obeyed.

Packet Forwarding
Packet forwarding is the relaying of packets from one network segment to another by nodes in a computer network. Models The simplest forwarding model unicastinginvolves a packet being relayed from link to link along a chain leading from the packet's source to its destination. However, other forwarding strategies are commonly used. Broadcasting requires a packet to be duplicated and copies sent on multiple links with the goal of delivering a copy to every device on the network. In practice, broadcast packets are not forwarded everywhere on a network, but only to devices within a broadcast domain, making ''broadcast'' a relative term. Less common than broadcasting, but perhaps of greater utility and theoretical significance, is multicasting, where a packet is selectively duplicated and copies delivered to each of a set of recipients. Networking technologies tend to naturally support certain forwarding models. For example, fiber optics and copper cables run directly from one m ...

Router (computing)
A router is a computer and networking device that Packet forwarding, forwards data packets between computer networks, including internetworks such as the global Internet. Routers perform the "traffic directing" functions on the Internet. A router is connected to two or more data lines from different IP networks. When a data packet comes in on a line, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. Data packets are forwarded from one router to another through an internetwork until it reaches its destination Node (networking), node. The most familiar type of Internet Protocol, IP routers are Residential gateway, home and small office routers that forward IP packet (other), IP packets between the home computers and the Internet. More sophisticated routers, such as enterprise routers, conne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journey Planner
A journey planner, trip planner, or route planner is a specialized search engine used to find an optimal means of travelling between two or more given locations, sometimes using more than one Mode of transport, transport mode. Searches may be optimized on different criteria, for example ''fastest'', ''shortest'', ''fewest changes'', ''cheapest''. They may be constrained, for example, to leave or arrive at a certain time, to avoid certain waypoints, etc. A single journey may use a sequence of several modes of transport, meaning the system may know about public transport services as well as transport networks for private transportation. Trip planning or journey planning is sometimes distinguished from ''route planning'', which is typically thought of as using private modes of transportation such as bicycle, cycling, Car, driving, or walking, normally using a single mode at a time. Trip or journey planning, in contrast, would make use of at least one public transport mode which ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
