Round-robin DNS
Round-robin DNS is a technique of load distribution, load balancing, or fault-tolerance provisioning multiple, redundant Internet Protocol service hosts, e.g., Web server, FTP servers, by managing the Domain Name System's (DNS) responses to address requests from client computers according to an appropriate statistical model. In its simplest implementation, round-robin DNS works by responding to DNS requests not only with a single potential IP address, but with a list of potential IP addresses corresponding to several servers that host identical services. The order in which IP addresses from the list are returned is the basis for the term ''round robin''. With each DNS response, the IP address sequence in the list is permuted. Traditionally, IP clients initially attempt connections with the first address returned from a DNS query, so that on different connection attempts, clients would receive service from different providers, thus distributing the overall load among servers. ...

Round-robin Networks
A wireless mesh network (WMN) is a communications network made up of radio nodes organized in a mesh topology. It can also be a form of wireless ad hoc network.Chai Keong Toh Ad Hoc Mobile Wireless Networks, Prentice Hall Publishers, 2002. A mesh refers to rich interconnection among devices or nodes. Wireless mesh networks often consist of mesh clients, mesh routers and gateways. Mobility of nodes is less frequent. If nodes constantly or frequently move, the mesh spends more time updating routes than delivering data. In a wireless mesh network, topology tends to be more static, so that routes computation can converge and delivery of data to their destinations can occur. Hence, this is a low-mobility centralized form of wireless ad hoc network. Also, because it sometimes relies on static nodes to act as gateways, it is not a truly all-wireless ad hoc network. Mesh clients are often laptops, cell phones, and other wireless devices. Mesh routers forward traffic to and from the gat ...

Round-robin Scheduling
Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing.Guowang Miao, Jens Zander, Ki Won Sung, and Ben Slimane, Fundamentals of Mobile Data Networks, Cambridge University Press, , 2016. As the term is generally used, time slices (also known as time quanta) are assigned to each process in equal portions and in circular order, handling all processes without priority (also known as cyclic executive). Round-robin scheduling is simple, easy to implement, and starvation-free. Round-robin scheduling can be applied to other scheduling problems, such as data packet scheduling in computer networks. It is an operating system concept. The name of the algorithm comes from the round-robin principle known from other fields, where each person takes an equal share of something in turn. Process scheduling To schedule processes fairly, a round-robin scheduler generally employs time-sharing, giving each job a time slot or ''quantum'' (its allowance ...

Round-robin Item Allocation
Round robin is a procedure for fair item allocation. It can be used to allocate several indivisible items among several people, such that the allocation is "almost" envy-free: each agent believes that the bundle he received is at least as good as the bundle of any other agent, when at most one item is removed from the other bundle. In sports, the round-robin procedure is called a draft. Setting There are ''m'' objects to allocate, and ''n'' people ("agents") with equal rights to these objects. Each person has different preferences over the objects. The preferences of an agent are given by a vector of values - a value for each object. It is assumed that the value of a bundle for an agent is the sum of the values of the objects in the bundle (in other words, the agents' valuations are an additive set function on the set of objects). Description The protocol proceeds as follows: # Number the people arbitrarily from 1 to n; # While there are unassigned objects: #* Let each per ...

Round-robin (document)
Round-robin is a document signed by multiple parties in a circle to make it more difficult to determine the order in which it was signed, thus preventing a ringleader from being identified. Origin The term dates from the 17th-century French ''Rond ruban'' (''round ribbon''). This described the practice of signatories to petitions against authority (usually Government officials petitioning the Crown) appending their names on a document in a non-hierarchical circle or ribbon pattern (and so disguising the order in which they have signed) so that none may be identified as a ringleader. Oxford English Dictionary cited at The Phrase Finder, September 29, 2002 This practice was adopted by sailors petitioning officers in the |
Round-robin Letter
A round-robin letter or Christmas letter is a letter, typically included with a Christmas card and sent to multiple recipients at the end of the year, in which the writer describes the year's events for themselves and/or their family. The round-robin letter has been the subject of much ridicule, particularly from the ''Guardian'' journalist Simon Hoggart Simon David Hoggart (26 May 1946 – 5 January 2014) was an English journalist and broadcaster. He wrote on politics for ''The Guardian'', and on wine for ''The Spectator''. Until 2006 he presented ''The News Quiz'' on BBC Radio 4. His journali ..., who pilloried examples of the genre in his newspaper column, as well as writing the book ''The Hamster That Loved Puccini: The Seven Modern Sins of Christmas Round-robin Letters''. One example Hoggart cited read: Critics have drawn attention to a number of typical negative characteristics of the letters, including the airbrushing of bad news, the "excruciating" level of banal de ...

Round-Robin Letter (Spanish–American War)
The Round-Robin Letter is the name of an incident in the United States Army that occurred between July 28 and August 3, 1898, during the Spanish–American War. After disease incapacitated thousands of Army soldiers in the wake of the Siege of Santiago, high-ranking officers of Fifth Army Corps drafted a round-robin letter demanding that the unit be sent back to the United States. Public release of the letter embarrassed the U.S. government. By July 28, 1898, malaria and yellow fever were rife among U.S. Army troops garrisoned near Santiago de Cuba on the island of Cuba. Fifth Corps, to which the Rough Riders was attached, had 4,270 men seriously ill (and dying), and corps commanders feared the unit could be wiped out if it stayed in Cuba.Wintermute, p. 558. The McKinley administration, however, planned to keep the corps in Cuba until peace negotiations with Spain concluded. Public opinion was also against bringing home an army infected with yellow fever.Golay, p. 104. Several se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round-robin Story
A round-robin story, or simply "round robin," is a type of collaborative fiction or storytelling in which a number of authors write chapters of a novel or pieces of a story, in rounds. Round-robin novels were invented in the 19th century, and later became a tradition particularly in science fiction. In modern usage, the term often applies to collaborative fan fiction, particularly on the Internet, though it can also refer to friends or family telling stories at a sleepover, around a campfire, etc. See also * Addventure, which combines the round robin method with gamebook narrative form * Exquisite Corpse Exquisite corpse (from the original French term ', literally exquisite cadaver), is a method by which a collection of words or images is collectively assembled. Each collaborator adds to a composition in sequence, either by following a rule (e.g. ...

Round-robin Test
In experimental methodology, a round-robin test is an interlaboratory test (measurement, analysis, or experiment) performed independently several times. This can involve multiple independent scientists performing the test with the use of the same method in different equipment, or a variety of methods and equipment. In reality it is often a combination of the two, for example if a sample is analysed, or one (or more) of its properties is measured by different laboratories using different methods, or even just by different units of equipment of identical construction. A round-robin program is a measurement systems analysis technique which uses analysis of variance (ANOVA) random effects model to assess a measurement system. Round-robin tests regarding occupational safety and health Companies are obliged to determine whether hazardous substances are in the air at the workplace by using appropriate measurements. To maintain the quality parameters for analytic procedures, the quali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round-robin Tournament
A round-robin tournament (or all-go-away-tournament) is a competition Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). Competition can arise between entities such as organisms, indiv ... in which each contestant meets every other participant, usually in turn.''Webster's Third New International Dictionary of the English Language, Unabridged'' (1971, G. & C. Merriam Co), p.1980. A round-robin contrasts with an elimination tournament, in which participants/teams are eliminated after a certain number of losses. Terminology The term ''round-robin'' is derived from the French term ''ruban'', meaning "ribbon". Over a long period of time, the term was Folk etymology, corrupted and idiomized to ''robin''. In a ''single round-robin'' schedule, each participant plays every other participant once. If each participant plays all others twice, this is freque ...

Turn-based Game
In video and other games, the passage of time must be handled in a way that players find fair and easy to understand. This is usually done in one of the two ways: real-time and turn-based. Real-time Real-time games have game time progress continuously according to the game clock. One example of such a game is the sandbox game ''Terraria'', where one day-night cycle of 24 hours is equal to 24 minutes in real time. Players perform actions simultaneously as opposed to in sequential units or turns. Players must perform actions with the consideration that their opponents are actively working against them in real time, and may act at any moment. This introduces time management considerations and additional challenges (such as physical coordination in the case of video games). Real-time gameplay is the dominant form of time-keeping found in simulation video games, and has to a large degree supplanted turn-based systems in other video game genres as well (for instance real-time strateg ...
