Connection-oriented vs Connection-less packet switching

-

 


Below shows the comparison of  connection-oriented packet switching network and connection-less packet switching ,

 

  • In connection oriented packet switching packets are follow a same route source to
    the destination while in connectionless packet switching packets don’t follow same
    route,so in connectionless packets may arrive to the destination in a random manner
    so it’s required to stored and rearrange the arriving packets. This is a disadvantage of
    connectionless over connection-oriented packet switching  

  • In connectionless packet switching when if there any kind of fault in some choosed
    transmission link then packets route in a alternative path ,so this is a advantage over
    connection oriented packet switching(because connection oriented packet switching
    there is a initial route setup between sender and receiver)
 
  • Connection oriented is reliable data transfer while connectionless is unreliable. In
    connectionless there is no initial setup of the connection between sender and the
    receiver for the data transfer, because of that it’s can’t guaranteed the delivery and
    the quality of service of the packets
 
  • In connection oriented if there is a failure in a link or a switch,the initial setup
    process want to repeat for all the routers and it’s need to store in a switch that the
    information of all the flows routed through that
 
  • Congestion is possible in the connectionless while it doesn’t happen in connection
    oriented.Because in connection oriented by it’s initially setup,network resources are
    reserved for the communication duration.So packets route though that without a
    congestion

  • Because of all packets in connectionless supposed to hold all the destination address
    and the routing information, so each packets need a lengthy field while it doesn’t
    need in connection oriented
 
  • There is a some delay in packet transferring until once the connection establish in
    connection oriented service while it doesn’t happen in connectionless packet
    switching because it doesn’t have a initial setup

  • Data transferring speed is higher in connectionless packet switching compared to the
    connection oriented packet switching , because in connectionless when packet
    sending by a network when it comes to a router then by that router forward that
    packet to the best router it knows(this process happen in connectionless until packet
    comes to the receiver)

Behavior of Average Queing Delay vs Traffic Intensity

-
Image
       Queuing delay is the waiting time of a packet to be transmitted in the buffer.But queuing delay cannot say exactly.It can vary from packet to packet.So this queuing delay based on below, Traffic arriving rate to the buffer,Transmission rate of the link, Nature of the arriving traffic(that mean arriving periodically or arriving bursts), Size of the buffer    La/R graph La-Average bit arriving rate R-Bits transmission rate (*here assume that the buffer is very big) When La/R>1      In this case, Arriving rate > Transmission rate, So then queue will tend to increase without bound, that mean average queuing delay will be infinity.Because there will be a congestion because of packets arriving to the buffer more faster rate than transmission out those. When La/R ≤ 1 In this case the average queuing delay affects on the nature of packets arriving, If packets arrive periodically-then each packet arrives at L/R seconds.In this each packet arrive to an empty queue so there will

Data Mining(Nursey data set)

    1.       Selecting an appropriate data set   Description about the data set Nursery data set was taken from UCI Machine Learning Repository. Nursery database was derived from a hierarchical decision model originally developed to rand applications for nursery schools and it was used during several years in 1980’s when there was excessive enrollment to these schools in Ljubljana, Slovenia and the rejected applications frequently needed an objective explanation. Here the final decision depended on 3 subproblems that are occupation of parents and child’s nursery, family structure and financial standing and social and health picture of the family. This Nursery dataset is a multivariate dataset with categorical data type values(except 1 attribute). And it consists with 8 attributes and 12960 instances. Below shows the table with attributes information, (UCI Machine Learning Repository: Nursery Data Set, 2021)                                       Table 01 : Attribute informa

How to create custom page borders in WORD

-
Image
      By using following steps , you can make a custom bordered template easily.And this will work on MS word 2013,2016 and 2019 versions. In here I demonstrate a , 15mm all bordered template.   1. STEP 01 : Open MS WORD and select " blank document "        2. STEP 02: Select the " file " tab.   3. STEP 03: Select " Account " .   4. STEP 04: Select " Advanced " in the pop-up window(word options).     5. STEP 05: Select  the units of measurement that you want in the drop down menu (here I use    millimeters). And press " ok " after select.   6. STEP 06: Select " Layout " tab.   7. STEP 07: First select " Margins " and then Select " Custom margins ".   8. STEP 08: Set your margin size as you wish (In here, I make all sides 15mm bordered template.So I set all margins as 15) .After set the margins press " ok " .     9. STEP 09: First select " Design " tab and then select " page border
