What is the difference between streamed datagram and raw sockets?
The datagram socket is a connectionless service. The raw socket allows direct access to lower layer protocols, such as IP and the ICMP. This interface is often used to test new protocol implementation, because the socket interface can be extended and new socket types defined to provide additional services.
Is raw socket reliable?
Stream sockets provide the most reliable connection. Datagrams and raw sockets are unreliable because packets can be discarded or duplicated during transmission.
What is a Tcpstream?
This feature allows you to follow a particular TCP conversation between two or more hosts. It finds all the TCP packets between a particular source and destination and reassembles the data that was transferred in that particular exchange into something parsable.
What is difference between socket and DatagramSocket?
2 Answers. A ServerSocket is for accepting incoming network connections on some stream protocol; e.g. TCP/IP. A datagram is bunch of information sent in a single logical packet.
What is the difference between a datagram and a frame?
I know that datagrams are packets at the transport layer of the OSI model, whilst frames are the name for packets in the transport layer and network packets are in the network layer. I also know that each contains a header with overhead info like the source and destination IP addresses, as well as a payload of data.
What is the difference between datagram and virtual circuit?
A Datagram based network is a true packet switched network. There is no fixed path for transmitting data. A virtual circuit network uses a fixed path for a particular session, after which it breaks the connection and another path has to be set up for the next session.
Why is raw socket needed for sniffing?
Basic Sniffer using sockets Put it in a recvfrom loop and receive data on it. A raw socket when put in recvfrom loop receives all incoming packets. This is because it is not bound to a particular address or port.
Is UDP a stream?
Stream Versus Packet — TCP/IP is a stream-oriented protocol, while UDP is a packet-oriented protocol. UDP, on the other hand, is a packet-oriented protocol where the application itself divides the data into packets and sends them to the other end. The other end does not have to reassemble the data into a stream.
