  as far as i know packets are data in small form.
  sorry if i am wrong about this.

  yes vinod you are right packets are actually data
  but my question how can we estimate speed of packets and on what factors does it depends?

  I dont know the actual speed and i think its a little bit tuf job to do.....as it depends on various factors like cable quality or what type of connection u are using i.e. its a wi-fi,broadband or 3G.

  It should depend on the data rate of a connection, processing time at the switches and routers and the QoS parameters of the connection.
  For eg if you take a LAN with hub , then you might expect delays becasue of the shared communcation media as the bandwidth is divided between all the ports.
  If you talk about LAN with a switch, all the bandwidht is dedicated to one port at one time.

  Assuming that All the network infrastructure like Routers, Switches, cables..etc. is perfect & operating on the same speed 1 Gbit for example and the other end's infrastructure is similar then we're talking perfect as sender-receiver & assuming the packets cables way from the sender to the receiver is perfect & at least Cat5...
  
  Simply, assume everything is perfect & operates at the same speed (1 Gbit/sec), the 32-bit packet will be transferred in :
  
  1 Gbit = 1099511627776 bits
  
  32/1099511627776 = 2.9 x 10^-11 of a second. (2900 nanoseconds)
  
  Finally, assume that all what I assumed is right.

  hehe! Maro, you do it the practical way ( data rate)😁
  
  but that value is valid only for a 4 byte packet ona gigabit datarate right?
  If you consider a voip packet the MTU can go as high as 1500 bytes right??? so dont you think the baove value migth vary???

  Change the variables as you need, I just *invented* the law 😁

  Ultimate law. Completely agree with it. 😁

  As in internet information is transferred in the form of packets?
  can anyone tell me what is speed of these packets and if it is not fixed on what factors does it depends?

  it is mainly depend on the bandwidth of the cable which is used for communicate.

  actually packet is a small module of data.
  i think packet speed is depend on the bandwidth of the cable which is used to communicate.
  sorry, if it is wrong ?

  Packets here means IP packets, whole packet is never send together. Packets are broken into fragments & each fragment has its identification no. . So it will be more specific if we talk about ip fragments.
  Ok. suppose we have a line from Delhi to New York, its a direct connection, no routers in between. In that case its speed will be comparable to the speed of electron in the physical layer of tcp model which is comparable to the speed of light.
  Now put some 10 routers or switches or hubs in between, now speed of packet (or fragments) will be affected by QoS & queuing algo of the network devices. You can infact see how many routers are between your pc & another pc by command > tracert IP_address
  
  Many people here are talking about bandwidth, its just means no. of fragments hitting your system. If you have 3G connection you will have more bandwidth & if you have dialup then less bandwidth, there's no affect on speed of packets.
  There can't be any formula to determine the packets speed without taking into account the characterstics of network devices used.
  one more thing that many people don't know is all the continents are connected by wires laid in the oceans that's responsible for our internet.
