When first connected to a network, a host sends a link-local router solicitation multicast request for its configuration parameters ; if configured suitably, routers respond to such a request with a router advertisement packet that contains network-layer configuration parameters.

When an unlabeled packet enters the ingress router and needs to be passed on to an MPLS tunnel, the router first determines the forwarding equivalence class ( FEC ) the packet should be in, and then inserts one or more labels in the packet's newly created MPLS header.

When a labeled packet is received by an MPLS router, the topmost label is examined.

When a data packet comes in one of the lines, the router reads the address information in the packet to determine its ultimate destination.

When each router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the network addresses in the routing table.

When packets arrive at a router, they have to be processed and transmitted.

When a router forwards a packet to a host, such as a web server, that host is on the same network as a router's directly connected network.

When using a plunge-base router, the sole of the base is placed on the face of the work with the cutting bit raised above the work, then the motor is turned on and the cutter is lowered into the work.

When a reply returns to the router, it uses the connection tracking data it stored during the outbound phase to determine the private address on the internal network to which to forward the reply.

When the packet arrives at an intermediate router for forwarding, the router examines the header ( very quickly ), sets up a circuit to the next router, and then bows out of the conversation.

When the timer expires, the router will then receive its routing updates from other routers.

When ECN is successfully negotiated, an ECN-aware router may set a mark in the IP header instead of dropping a packet in order to signal impending congestion.

When one of these paths repeatedly changes its state from available to not available ( and vice-versa ), the BGP router controlling that path has to repeatedly add and remove the path record from its routing table ( flaps the path ), thus spending local resources such as CPU and RAM and, even more, broadcasting useless information to peer routers.

When a router receives a packet marked as ECN capable and anticipates ( using RED ) congestion, it will set an ECN-flag notifying the sender of congestion.

When a router receives the RSVP resv message it will:

When a planned withdrawal of a master router is to take place, its priority can be lowered which means a backup router will pre-empt the master router status rather than having to wait for the hold time to expire.

When a router does not wish to receive this group's data ( if no other neighboring PIM routers are present and no host is interested in the group ), it sends a Prune message to indicate its lack of interest.

When a multicast packet is received by a router, it is forwarded by the router's interfaces specified in the routing table.

When animators or interface designers talk about the " physics " or " feel " of an operation, they may be referring to the particular Bézier curve used to control the velocity over time of the move in question.

When using IMAP4, clients often stay connected as long as the user interface is active and download message content on demand.

When introduced in the early 1990s, it had a number of unique features, such as “ sync slip ”, synchronized varispeed playback with audio scrubbing, synchronized multi-channel playback, and an object-oriented user interface with a dedicated hardware console.

When a beam of white light passes from air into a material having an index of refraction that varies with frequency, a phenomenon known as dispersion occurs, in which different coloured components of the white light are refracted at different angles, i. e., they bend by different amounts at the interface, so that they become separated.

When video displays first became available the user interface was initially exactly the same as for an electromechanical printer ; expensive and scarce video terminals could be used interchangeably with teleprinters.

When MS-DOS adopted the Xenix-like file interface of file handles, FCBs became a legacy interface supported for backward compatibility.

When a voltage is applied between the gate and body terminals, the electric field generated penetrates through the oxide and creates an " inversion layer " or " channel " at the semiconductor-insulator interface.

When a light ray is incident from a medium of refractive index n to the core of index n < sub > core </ sub > at the maximum acceptance angle, Snell's law at the medium – core interface gives

When the PDU passes over the interface from the layer that constructed it to the layer that merely delivers it ( and therefore does not understand its internal structure ), it becomes a service data unit to that layer.

When a lead – acid battery is charged or discharged, this initially affects only the reacting chemicals, which are at the interface between the electrodes and the electrolyte.

When the cursor hovers over a link, depending on the browser and / or graphical user interface, some informative text about the link can be shown, popping up, not in a regular window, but in a special hover box, which disappears when the cursor is moved away ( sometimes it disappears anyway after a few seconds, and reappears when the cursor is moved away and back ).

When castling using a computer interface, programs should have separate a-side ( 0-0-0 ) and h-side ( 0-0 ) castling actions ( e. g., as a button or menu item ).

When the context-sensitive help function is turned on, typically the mouse-pointer changes to an arrow with a question mark to indicate that clicking a user interface element will result in opening a help window.

When the interface clock rate is increased to a point where its inverse ( i. e., its clock period ) is shorter than the largest possible time between signal arrivals, the signals no longer arrive with sufficient coincidence to make recovery of the transmitted word possible.

When a fluid element is displaced on an interface or internally to a region with a different density, gravity tries to restore the parcel toward equilibrium resulting in an oscillation about the equilibrium state or wave orbit.

When the interface between these two surfaces is not horizontal and the system is close to hydrostatic equilibrium, the gradient of the pressure is vertical but the gradient of the density is not.

When separated, the connection may be made to specialized intermediate hardware, a frame grabber using either a standardized ( Camera Link ) or custom interface.

When Digital Research founder Gary Kildall examined PC DOS and found that it duplicated CP / M's programming interface, he wanted to sue IBM, which at the time claimed that PC DOS was its own product.

When IBM implemented the parallel interface on the IBM PC, they used the DB25F connector at the PC-end of the interface, creating the now familiar parallel cable with a DB25M at one end and a 36 pin micro ribbon connector at the other.

When the binary interface of the hardware the executable was compiled for differs from the binary interface on which the executable is run, the program that does this translation is called an emulator.

When Heidegger and Sartre speak of a contrast between being and existence, they may be right, I don't know, but their language is too philosophical for me.

When they express themselves it is incandescent hatred that shines forth, the rage of repudiation, the ecstasy of negation.

When I try to work out my reasons for feeling that this passage is of critical significance, I come up with the following ideas, which I shall express very briefly here and revert to in a later essay.

When the proprietor dies, the establishment should become a corporation until it is either acquired by another proprietor or the government decides to drop it.

When the reactionary response is thus bolstered by an intellectual defense, the characteristics of that defense are explicable only in terms of the basic attitudes of unanalyzed reaction.

When decision makers act within this frame they determine whether a claim put forward in the name of religion is to be accepted by the larger community as appropriate to religion.

When we consider the disorganized state of the world community, and the legacy of predispositions adversely directed against all who are identified as Jews, it is obvious that the struggle for the minds and muscles of men needs to be prosecuted with increasing vigor and skill.

When we turn to Aristotle's ideas on the moral measure of literature, it is at once apparent that he is at times equally concerned about the influence of the art.

When their faith in civil liberties is tested against strong pressures of social expediency in specific issues, e.g., suppression of `` dangerous ideas '', many waver and give in.

There is, of course, nothing new about dystopias, for they belong to a literary tradition which, including also the closely related satiric utopias, stretches from at least as far back as the eighteenth century and Swift's Gulliver's Travels to the twentieth century and Zamiatin's We, Capek's War With The Newts, Huxley's Brave New World, E. M. Forster's `` The Machine Stops '', C. S. Lewis's That Hideous Strength, and Orwell's Nineteen Eighty-Four, and which in science fiction is represented before the present deluge as early as Wells's trilogy, The Time Machine, `` A Story Of The Days To Come '', and When The Sleeper Wakes, and as recently as Jack Williamson's `` With Folded Hands '' ( 1947 ), the classic story of men replaced by their own robots.

When I first came across Samuel Johnson's pronouncement, `` the remedy for the ills of life is palliative rather than radical '', it seemed to me to sum up the profoundest of political and social truths.

When we become firm enough to stand for those ideals which we know to be right, when we become hard enough to refuse to aid nations which do not permit self-determination, when we become strong enough to resist any more drifts towards socialism in our own Nation, when we recognize that our enemy is Communism not war, and when we realize that concessions to Communists do not insure peace or freedom, then, and only then will we no longer be `` soft ''.

When one powerful nation strives to emulate the success of another, it is only natural.

When a man is laid to rest, he is entitled to stay put.
