Sequenced Packet Sockets − These are just like a stream socket, Along with the exception that report boundaries are preserved. This interface is offered only as being a part of the Community Units (NS) socket abstraction, and is vital in many really serious NS programs. Sequenced-packet sockets enable the user to control the Sequence Packet Protocol (SPP) or Web Datagram Protocol (IDP) headers over a packet or a group of packets, either by crafting a prototype header as well as whichever knowledge would be to be sent, or by specifying a default header for use with all outgoing details, and makes it possible for the person to receive the headers on incoming packets.

During the customer’s principal script, application-consumer.py, arguments are study from the command line and applied to produce requests and begin connections towards the server:
You can see this in motion When you have an software server that works by using its individual personal database. If it’s not a databases utilized by other servers, it’s almost certainly configured to listen for connections within the loopback interface only. If this is the scenario, other hosts within the fit external socket community can’t connect with it.
You should use this segment as being a basic reference with further details and backlinks to exterior methods.
