Consider an error-free 64 kbps satellite channel used to send 512 byte data frames in one direction, with very short acknowledge
Vladimir [108]

Answer:

The answer is "2".

Explanation:

In the given question some information is missing, that is "The propagation time for satellite to earth" which is "270 milliseconds" so, the description to this question can be defined as follows:

Given values:

Bandwidth = 64 kbps

Data frames = 512 bytes  

Propagation Time (t​​​​​​p ) =270 ms

Change Bandwidth  kbps to bps:

1 kb= 1024 bytes

calculated bandwidth= 64 kbps = 64×1024 bps = 65536 bps

1 bytes = 8 bits

512 bytes = 512 × 8 =  4096 bits

Frame length = 4096 bits

Formula

Transmission time (T​​​​​​t) = Frame length /Bandwidth

Window size = 1+2a

where a = Propagation time/Transmission time

Calculate Transmission time:

Transmission time (T​​​​​​t) = 4096 / 65536

Transmission time (T​​​​​​t)= 625 m.sec

Calculate Window size:

Window size = 1+2(270/625)

Window size = 1+2(0.432)

Window size = 1+0.864

Window size = 1.864

Window size = 2

Describe at least one reason why transitioning from the Cisco implementation of STP to the Cisco implementation of RSTP is seaml
kherson [118]

Answer:

STP mainly uses 5 states in a network, in which some states are replaced in RSTP which improves the time efficiency.

Explanation:

STP mainly uses five states i.e.  Learning, Listening, Blocking, Disabling and Forwarding to overcome the problem of collision in a network.  

RSTP replaced the three states of STP i.e listening, learning, and blocking by Discarding, which results in the time efficiency as compared to STP.  

As STP takes minutes to complete the network inter connectivity, RSTP completes it in seconds.

This is one of the main reason why an administrator want to change to RSTP.
