IEEE 802.6 standard i.e. DQDB(Distributed Queue Dual Bus) is a MAN(Metropolitan Area Network) protocol. It can be defined as a high speed shared medium access control protocol that is used over a bus network. It has two unidirectional buses, for controlling purposes, where the bus can carry data, video, and voice over a network with bandwidth being allocated as per time slots. The advantage of using the paired bus is that it is used to tackles failure configuration. It can be extended up to 30 miles at 34-55 Mbps.

CS GO and dropped due to slot reservation Havin an issue, every game after I play, I am kicked to the start screen and have to reconnect to the game server im playing, I sometimes get the message that I was dropped due to slot reservation. The date/time of the reservation/absence. If the Whole Day slider is active, it will reflect the entire day. If not, it will display the from and to date/times entered. Time Slot: The selected reservation or absence type. Reservation and absence types are managed in the Time Slots tab in the Planning & Dispatching settings. Dropped Due Slot Reservation Cs 1 type – also called video table games – are exactly what they sound like: You are playing a game on an RNG (random number generation) platform Dropped Due Slot Reservation Cs 1 that offers you the same odds to win as brick-and-mortar casinos.
Fig.1:- Working of DQDBDirectional Traffic:
Each bus support traffic in only one direction and are opposite to one another. The start of the bus being represented as a square and the end of the bus being represented as a triangle (Fig.1). Bus A traffic moves from right to left (i.e. from station 1 to 5) whereas the bus B traffic moves from left to right (i.e. from station 5 to 1).
Upstream and Downstream:
The relationship of stations of the DQDB network depends on the directional flow of traffic of the buses.
Considering bus A in Fig.1, which has station 1 & 2 marked as upstream w.r.t station 3 and station 4 & 5 are downstream w.r.t station 3. Here in bus A, station 1 is head of the bus as there is no upstream station and station 5 has no downstream station and it is regarded as to end of bus A.
Working:
The head of the bus A i.e. station 1 generates empty slot for use of bus A. Similarly, the head of bus B i.e. station 5 generate empty slot for use of bus B. The empty slot travels down its bus until the transmission station drops data into it and intended destination reads the data.
For example:
If station 2 wants to send data to station 4 (Fig.2), it chooses a slot on bus A as station 4 is downstream in bus A. The head of the bus A i.e. station 1 creates an empty slot. Station 2 drops its data & address of destination slot into the passing slot. Station 3 reads the address and passes the slot as unread. Station 4 recognizes its address, reads the data and changes the status of the slot and passes it along with station 5 where it is absorbed.
How slot reservation is done?
To send data downstream, a station must wait for the arrival of the unoccupied slot, but here the question arises that how to stop an upstream station from manipulating the bus due to which the station near the end of the bus suffers, as the imbalance can lead to degraded quality of service. The solution to this problem is to do a reservation at the station. Here station 2 can make a reservation for bus A on bus B. Station 2 sets a reservation bit on a slot on bus B to tell each station it passes through, that the station is reserving a slot on bus A. All the station must respect the reservation of downstream station and leave the slot for requested station.

A slot canyon is a long, narrow, deep and tortuous channel or drainageway with sheer rock walls that are typically eroded into either sandstone or other sedimentary rock. A slot canyon has depth-to-width ratios that typically exceed 10:1 over most of its length and can approach 100:1. The term is especially used in the semiarid western United States, including the Colorado Plateau region. Slot canyons are subject to flash flooding and commonly contain unique ecological communities that are distinct from the adjacent, drier uplands.[1] Some slot canyons can measure less than 1 metre (3 ft) across at the top but drop more than 30 metres (100 ft) to the floor of the canyon.
Many slot canyons are formed in sandstone and limestone rock, although slot canyons in other rock types such as granite and basalt are possible. Even in sandstone and limestone, only a very small number of streams will form slot canyons due to a combination of the particular characteristics of the rock and regional rainfall.
Slot canyons around the world[edit]
Slot canyons are found in many parts of the world, predominantly in areas with low rainfall. Some of the best-known slot canyons are to be found in the Southwestern United States. Other significant areas include the Sierra de Guara in northern Spain, the Pyrenees on the border of France and Spain, and the Blue Mountains in New South Wales, Australia.
Australia[edit]
The largest known area of slot canyons in Australia is in the Blue Mountains, west of Sydney. They occur in a narrow band of sandstone that runs roughly 30 kilometres (19 mi) from east to west, and about 100 kilometres (62 mi) from south to north. The majority of these canyons are in the Wollemi Wilderness, and are difficult to access. A small number are regularly visited by canyoners on weekends in summer. The Grand Canyon, near Blackheath, has a tourist track along its rim, but requires abseiling (rappelling) or swimming to visit fully.
Sandstone slot canyons can also be found in a few more remote parts of Australia, including Karijini National Park and the Bungle Bungles in Purnululu National Park, both in Western Australia, and Carnarvon Gorge in Queensland.
United States[edit]
Southern Utah has the densest population of slot canyons in the world with over one thousand slot canyons in the desert lands south of Interstate 70.[2] Utah's slot canyons are found in Zion National Park at The Narrows, along Canyonlands National Park's Joint Trail, throughout Capitol Reef National Park, within the San Rafael Swell and the Grand Staircase-Escalante National Monument, especially along the Escalante River drainage including Coyote Gulch. Many more slot canyons are located on public Bureau of Land Management and state-owned lands in southern Utah, in areas surrounding the aforementioned parks and monuments. Buckskin Gulch—one of the longest slot canyons in the world—begins in southern Utah and continues into northern Arizona within the Paria Canyon-Vermilion Cliffs Wilderness. Northern Arizona also has a high concentration of slot canyons including Antelope Canyon and Secret Canyon, which are two of the most famous slot canyons located near Page on land owned by the Navajo Nation. Slot canyons are also located in the valley between U.S. Route 89 and the Vermilion Cliffs in Arizona, and can be seen as one descends into the valley on U.S. 89, but these are on the Navajo reservation and are closed to the public. The Kasha-Katuwe Tent Rocks National Monument's slot canyon trail in New Mexico is unique as it was carved into tuff (volcanic ash). In California, several slot canyons are located within Death Valley National Park.

Drowning danger[edit]
Local as well as distant storms can cause dangerous flash flooding in slot canyons, and hikers should not enter them if there is any sign of rain in the surrounding area.[3] In many slot canyons, it can be miles before a safe exit or rescue is possible.
On August 12, 1997, eleven tourists, including seven from France, one from the United Kingdom, one from Sweden and two from the United States, were killed in Lower Antelope Canyon by a flash flood.[4][5] Very little rain fell at the site that day, but an earlier thunderstorm had dumped a large amount of water into the canyon basin, seven miles upstream. The lone survivor of the flood was tour guide Francisco 'Poncho' Quintana, who had prior swift-water training. At the time, the ladder system consisted of amateur-built wood ladders that were swept away by the flash flood. Today, ladder systems have been bolted in place, and deployable cargo nets are installed at the top of the canyon. Casinos near mcgaheysville va. A NOAA Weather Radio from the National Weather Service and an alarm horn are stationed at the fee booth.[6]
