Which node has to wait for their time slot for transmission?
relaying node
When a packet arrives at a relaying node, it has to wait for its time-slot allocated for transmission. The delay at each hop is accumulated along the path. Thus, improper time-slot assignment significantly increases the delay especially when the number of hops of a path is large.
How do you calculate propagation time?
The propagation delay of a physical link can be calculated by dividing the distance (the length of the medium) in meter by its propagation speed in m/s.
How long is the collision domain in a 100 Mbps Ethernet network?
100-meter
In a fully switched (that is, no hubs) 100BASE-TX LAN, each collision domain is simply a single twisted-pair link, subject to the 100-meter maximum length. Fast Ethernet also introduced the concept of full-duplex Ethernet: two twisted pairs could be used, one for each direction.
What is slot time of 10 Mbps system?
0.1 microseconds
So, in 0.1 microseconds (the time to send one bit at 10 Mbps), the signal propagates approximately 0.77×c×10-7 = 23 meters. Ethernet packets also have a maximum packet size, of 1500 bytes.
When two or more nodes transmit at the same time what will occur?
Because all nodes are capable of transmitting frames, more than two nodes can transmit frames at the same time. When this happens, all of the nodes receive multiple frames at the same time, that is, the transmitted frames collide at all of the receivers.
What is maximum propagation time?
The maximum time until a node detects a collision is twice the propagation time of a signal between the nodes that are farthest apart. The time taken to transmit a packet that collides is wasted because the two nodes must abort their transmission and restart after some random delay.
Can you have two WIFI boxes one house?
Yes, you absolutely can have two separate connections in your house. With the two separate wireless routers you would need to set them on non-overlapping channels and you will be fine.
What is the slot time required?
Slot time is the time required for a signal to traverse from one end of the network to another, plus the time required to send the jam signal in case of collision. Assume the propagation speed is 2×108 m/s, the maximum length can be 5120m or 4096m.
