Q.In a distributed system, three manners in which the transportation layer switch can be implemented are Network Address protocol, TCP hands-off, and via proxy.Can you briefly describe the three manners above?

Answer:

Network Address protocol:

The idea of NAT is to allow multiple devices to access the Internet through a single public address. To achieve this, the translation of private IP address to a public IP address is required. Network Address Translation) is a process in which one or more local IP address is translated into one or more Global IP address and vice versa in order to provide Internet access to the local hosts. Also, it does the translation of port numbers i.e. masks the port number of the host with another port number, in the packet that will be routed to the destination. It then makes the corresponding entries of IP address and port number in the NAT table.An internet protocol address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.

TCP hands-off:

The TCP handoff is totally transparent from the client's point of view. Since it operates on transport-level streams, clients can never be aware of being redirected. They send their requests to the service machine and do not know that the intermediate gateway switches them between replicas.a TCP 3-way handshake is a process which is used in a TCP/IP network to make a connection between the server and client. It is a three-step process that requires both the client and server to exchange synchronization and acknowledgment packets before the real data communication process starts.

proxy:

A proxy server acts as a gateway between you and the internet. It’s an intermediary server separating end users from the websites they browse. Proxy servers provide varying levels of functionality, security, and privacy depending on your use case, needs, or company policy.If you’re using a proxy server, internet traffic flows through the proxy server on its way to the address you requested. The request then comes back through that same proxy server and then the proxy server forwards the data received from the website to you.
