To verify that the recipient received the frame correctly, a checksum verifies the packet (similar to a hash value) for correctness. The TCP packet confirms receipt of a packet with the Piggy-Backing ( Acknowledgment Number ) from the receiver. In order to assign them correctly, the recipient must assemble the TCP packets according to the order of the sequence number. The transmitter split a frame into many pieces ( sequences ). The TCP begins with the port numbers (compare to a house with multiple front doors) and the sequence numbers of the TCP packet. The TCP contains functions that are used to…Īre used for transmission. TCP – pays attention to completeness, sequence and correctness The source and destination IP addresses (receiver and sender) are specified in the Source and Destination fields. The header checksum is a checksum that the network card can use to verify the correct transmission of the IP header. When the Time To Live has reached 0, the packet is deleted. The number for Time To Live indicates the number of routers (hops or in seconds) that an IP packet is allowed to traverse. Instead, version 6 uses the longer 128-bit addresses, which allow for a larger address space. In the early days of IP allocation, some organizations were given huge address spaces that were ” wasted ” in the process. Version 4 has reached its limit of available addresses (4.2 billion addresses). This frame uses the legacy Internet Protocol (IP) version 4:

The first three octets of the MAC address are reserved for the manufacturer ( organizationally unique identifier ) and the last three octets are reserved for the network interface controller. The physical MAC address from the screenshot indicates that the receiver and the transmitter must have an Asus motherboard (more precisely: BaseBoard Manufactur ASUSTeK COMPUTER INC. Wireshark visualizes the types of the application layer protocol with different colors: Green means that an HTTP protocol is present (HTTP port 80). IP, TCP, HTTP and urlencoded-form included. In addition to this information, the protocol also contains the size of the packet ( frame length ) and the size it contains ( capture length ). The receiver recognizes the frame with the frame number.

The encapulation type is the type of “packet” that the PC received. (Picture above) Let’s look at level 2 of the OSI model: The Frame tab shows information about the data packet that went over the line. If you look at an Ethernet frame in Wireshark, you will see the following text: The protocols are necessary so that the recipient understands the user data and the communication works uniformly and independently of the platform.

ARP – Address Resolution Protocol for MAC resolution on the router.

RDP – Remote Desktop protocol for the transmission of screens.

UDP – Fast packets for video and audio (streaming).

ICMP – exchange error messages in the network.

Wireshark records every Internet packet (no matter what protocol or size) that arrives at your Ethernet connection. Wireshark is a network sniffer, Sniffing means “monitoring”, “investigating” or “spying”. This tutorial is intended to explain to you bit by bit what you can read out of an Ethernet frame (file packet of the Internet). The Wireshark Network Sniffer is a network analysis tool that gives the network administrator deep insight into network activity.

TCP – pays attention to completeness, sequence and correctness.
