What can be indentified by examining the network layer header?
IP Source and IP Destination n
What can be identified by the network layer header?
destination host address
Which OSI layer header contains the address of a destination host that is on another?
Network Layer
What can be identified by examining the network layer hearder?
host adderss
Why header and trailer is present in network layers?
HEADERS: It is a part of an information structure that precedes and identifies the information that follows,such as block of bytes in communication.TRAILERS:It is an information typically occupying several bytes ,at the tail end of a block of transmitted data which may contain a checksum or other error-checking data useful for confirming the accuracy and status of transmission.
What information is found in the network layer header?
The destination host address
What protocols at other layers of the OSI model does ping use?
Layer 3 of the OSI model. An ICMP header follows the IP header of the IP packet.
What are three functions of the upper data link sub layer in the OSI model?
insulates network layer protocols from changes in physical equipment makes the connection with the upper layers identifies the source and destination identifies the network layer protocol
What can be identified by examining network layer encapsulation?
IP source and destination address
When creating a packet how does the network layer determine the size of the packet?
The Network layer (Layer 3, typically IP) will receive a segment from the Transport layer (Layer 4, typically TCP or UDP), and will add its own header to it to create a packet. The size of the packet will thus always be the size of the segment plus the Network layer header, the same as when the next layer down (the Data Link layer, layer 2, typically Ethernet) encapsulates the packet into a frame for transmission.
Which OSI layer is responsible for adding a header that includes routing information?
The routing process occurs in the 3rd OSI layer (network layer) routing protocols use network address (IP address in TCP/IP) to chose the correct path to the destination. ps: You can also have routing protocols on other layers sometimes (application layer in p2p routing) but this is something completely different.
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.
