Difference between transport and network layer?
+network layer logical communication between hosts +transport layer: logical communication between processes ex: we have 2 house and one house have 12 room. kids in the houses send letter together. network layer: only send letter between the houses transport layer: it make sure that the letter be sent to right the room in the house.
Which OSI layer protocol does IP rely on to determine whether packets have been lost and to request retransmission?
-Transport Layer
How do you calculate packet delivery ratio in MANET?
I think PDR= Packets Received / Packets Sent Packets sent/received values should be from same layer. i.e. all from application layer or network layer...etc
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.

Lost transport layer packets?
Transport layer is the fourth layer in the OSI model. Transport layer is responsible for process to process delivery of entire message. Other than that it also control connection, flow of data and error , thus will resend the packet if it get lost in between.
At what layer of the OSI does data become a packet?
Different textbooks may give you different answers to this question. In several I've seen, the "packet" is complete in the data link layer (layer 2) and is known as a 'frame' in the physical layer (layer 1). Others may indicate a packet is the result of the physical layer (layer 1). In other descriptions the terms packet and frame are interchanged in the layer 1 and 2 of the OSI model.
Do frame encapsulate packet or do packet encapsulate frame?
Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".
What is a network layer data gram?
A packet.A packet.A packet.A packet.
Do frame encapsulate packet or packet encapsulate frame?
Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".
What osi layer does packet filtering happen at?
Layer 3,4 and 7
Functions of transport layer?
Transport Layer, this layer allows data to be broken into smaller packages for data to be distributed and addressed to other nodes (workstations). Main functions are multiplexing, De multiplexing, error control, flow control.
