marking packets with the router's IP address, analysis shows that in order to gain the correct attack path
packet switching is use today
monitor traffic and ongoing attacks
Stateful packet inspection
If we are sending a file in one go and if some error occurred in between the file transfer then the complete file has to be resend which wastes the bandwidth so to prevent this, the file to send is divided in to smaller unit which we call packet, and then send packets 1 by one so that if a packet is lost then we need to send only that particular packet not the complete file. As the packet reaches its destination, the destination source send acknowledgement to the sender that the packet has reached to it and it may send the next packet and if packet somehow lost before reaching to the destination source, then the sender itself resends the packet after a fixed amount of time.

A connection based protocol requires a technique known as hand-shaking. This means that every packet that is transmitted requires a response from the receiver indicating that they received the packet and that the packet arrived safely. There is a 3-way startup sequence to create a connection using handshaking protocol.
First step to design a network is to prepare a layout . Then Protocols which are to be applied are decided. A network can be designed on Packet tracer (software) .
There are ways in which packets are filtered and fowarded through the network.1.circuit switching2.message switching3.packet switching4.cell switching
fast packet switching: A packet switching technique that increases the throughput by eliminating overhead. Note 1: Overhead reduction is accomplished by allocating flow control and error correction functions to either the user applications or the network nodes that interface with the user. Note 2: Cell relay and frame relay are two implementations of fast packet switching.
it can bring on asthma attacks especially if you are allergic to aspirin.To be safe I would ask your Dr as the packet does give warnings to people with asthma not to take it.
In this technique, an attacker sends packets with an incorrect source address. when this happens the receiver i.e the party who receives the packets containg a false source address would inadvertently send replies back to the forged address and not to the attacker
a japanese technique, focused on cravings, worked for me, hyperurl.co/arwkdx make sure you thank me if you will get success 🙂 God Bless You!
