|
Processing Delay
|
Time required to examine the packet's header and determine where to direct the packet.
|
[no formula - depends on router]
|
|
|
Queuing Delay
|
Time a packet is waiting in the queue to be transmitted onto the link.
|
[no formula - depends on how full queue is]
|
|
|
Transmission Delay
|
Amount of time required to push, transmit, all of the packet's bits into the link. (Microseconds to milliseconds)
|
Dtrans = L/R
L = length of the packet (bits) R = transmission rate of the router (bits/second) |
|
|
Propagation Delay
|
Time requrired to propagate from the beginning of the link to router B. A bit propagates at the propagation speed of the link.
|
Dprop = d/s
d = distance between router A nd router B s = propagation speed of the link (in range from 2 * 10^8 m/sec to 3 * 10^8 m/s - around or less than speed of light) |
|
|
Bandwidth Delay Product
|
= R * Dprop
|
|
|
|
Length of bit
|
= length of link / bandwidth delay product
= length/ (R * Dprop) |
|
|
|
1 Kb = ? bits
|
1000
|
|
|
|
1 Mb = ? bits
|
1,000,000
|
|
|
|
1 Gb = ? bits
|
1,000,000,000
|

|
|

|
A SYN flood attack, leaving half open connections.
