The technique of embedding one communication protocol within the header of a separate protocol is referred to as encapsulation. This process plays a pivotal role in facilitating data transmission across different network layers while ensuring seamless communication between devices. Encapsulation enables the integration of varying protocols, forming a harmonious and efficient data exchange environment.
In essence, encapsulation wraps the data from a higher layer protocol within the header of a lower layer protocol. This method allows data to traverse through different network layers, each contributing its own set of headers and trailers. The receiving end then decapsulates the data, removing headers and trailers sequentially to extract the original message.
Encapsulation is a fundamental component of networking models such as the OSI (Open Systems Interconnection) and TCP/IP (Transmission Control Protocol/internet Protocol). It promotes compatibility, modularity, and reliability in data communication, enabling various network devices and protocols to interact effectively.
What else can I help you with?
Which protocol's header includes the source MAC address?
The Ethernet protocol's header includes the source MAC address.
What does the protocol field in the IP header identify?
The protocol field, in the IP header, identifies what kind of data is in the IP packet - the upper-layer protocol. For example, if the code is 6, that means that the data is a TCP segment.
How does SMTP mark the end of a message body?
The HTTP protocol simply declares the entire length of the message in part of the header called "Content-length header field".
What is tcpip header and trailer?
An Ethernet frame has a 14 byte header, a data section, and a 4 byte trailer 14 byte header consist of destination address, source address and type The trailer is for CRC (Cyclic redundancy Check) An Ethernet frame can contain an IP and TCP PDU. IP header most important parts consists of (Version,IHL, Total length,Protocol, source and destination address) In details (Version,Header length,Differentiated services field, total Length, Identification, Flags, fragment offset, Time to live, protocol, header checksum, source and destination address). TCP header most important parts consists of (Source port, Destination port and header Length) In details (Source Port, Destination Port, Sequence number, Acknowledgment number, Header length,Flags,Window and check sum). The details of the IP and TCP header have been taken from a Network protocol Analyzer Wireshark on my own pc.
What type of header does an ARP frame contain?
ARP and RARP protocols are present at network layer. ARP is short form of address resolution protocol. IP is the type of header an ARP frame contain .
Which protocol's header includes the source MAC address?
The Ethernet protocol's header includes the source MAC address.
What is 'A' in GGA protocol header in NMEA protocol?
A MEANS aichi GAND.....
What does the protocol field in the IP header identify?
The protocol field, in the IP header, identifies what kind of data is in the IP packet - the upper-layer protocol. For example, if the code is 6, that means that the data is a TCP segment.
How many fields are there in IPv4 header?
UDP is a Transport layer protocol or fourth layer protocol. UDP is a connection less protocol used in transport layer. UDP header have four fields in total .
Which protocol header carries the physical address of host?
Ethernet
In the IP Protocol What is the header overhead?
Internet Protocol, or IP, puts a header on every packet that it sounds out. This header is the overhead. All protocols, such as TCP or UDP, will put a header on the packet. The IP header contains information such as source IP address and destination IP address and is used by routers to figure out where to send the packet. ex. you send your friend a 1kb file, but it takes up 1.5kb of bandwidth due to overhead
What IPv6 header field is used to identify the upper layer protocol or optional extension headers that are appended to the end of an IPv6 packet?
next header
If the Protocol field in the IP header has a decimal value of 17 it means that the higher level protocol using the services of IP is TCP?
no, service of UDP
AH and ESP protocol works on security in network layer?
The AH (Authentication Header) protocol and the ESP (Encapsulating Security Payload) protocol both function within the network layer. They are part of the IPSec (Internet Protocol Security) standard.
How does SMTP mark the end of a message body?
The HTTP protocol simply declares the entire length of the message in part of the header called "Content-length header field".
Which two TCP header fields are used to confirm receipt of data?
The Transmission Control Protocol (TCP) is a core protocol of the Internet protocol suite. The sequence number and acknowledgement number are used to confirm receipt of data.
