Write a 1 page paper on network protocol. Network protocols are the relevant rules, processes and data structures that clients in a network use to communicate with one another. The protocol acts like the languages that computers use in communication. Network protocols determine the format that determines an application for data transfer to ensure uniformity and conformity (Bush et al, 2012). The protocol helps define the transfer of information and therefore prevent the lack of a breach of treatment of information,

OSI model

In this model, the configuration used serves to describe the applications hasted on networks and the protocols. The model is split into seven parts. In the same token, the presentation layer deals with the production of services that rely on application program such as MSWindows.

According to the OSI model, the session layer has been set aside for the tabling of the running of services (Tanenbaum, 2003). This runs the process and leads to the scheduling of tasks that are to be run using the applications.

In the transport layer, responsibility vested is for the data being broken to packets for purpose of transfer between hosts on a regular basis to ensure the quality of service, on a network(Bush et al, 2012). Normally, network layers interpret the physical name of the computer from the logical network addresses.

Protocol orientation

Connection-oriented protocols are more reliable than the non-connection oriented ones. This is because they perform a check on their own structures. These protocols resend a message in case the receiver does not receive one (Forouzan, 2003). In this case, they tend to be more networks oriented. The non-connection oriented protocols are not session-based and can thus end at any time.

Hello, I am looking for someone to write an essay on Site to Site Internet Protocol Security. It needs to be at least 1500 words.

In VPN Tunneling technology, all traffic is forced through a secured site. Furthermore, one network is able to send its data via the connection to another network. The implementation of IPSec can take place at the end host or in the routers or even in both depending on the security requirements of the users (Doraswamy & Harkins 2003). With IPSec, any piece of information sent from one site to another remains secured due to the involved extensibility of the Internet Protocol layer. In this study, therefore, we will discuss tunneling, architecture, authentication and the associated standards in attempts to describe IPSec protocol. Of all VPNs, Tunnel Mode is the most commonly used in IPSec implementations Tunneling is the transmission of data intended for use within a private network through the public network. In this case, therefore, data is conveyed by a public network, which is the internet, on behalf of the private network. This is achieved through the protection of IP packets by the IPSec in such a way that the original packets get wrapped, encrypted and a new header added before being sent to the other side of the VPN tunnel (Tiller 2000). Configurations of IPSec VPN tunneling can also be done using Generic Routing Encapsulation (GRE) Tunnels with IPSec. The GRE is an encapsulation protocol of an arbitrary network layer protocol over another different arbitrary network layer protocol (Javin Technologies 2005). In this protocol, packets known as payloads need to be encapsulated and delivered to some destination. First, the payload is encapsulated in a GRE packet then in some other protocol before being forwarded. The outer protocol is known as a delivery protocol. “Security in a network using GRE should be relatively similar to security in a normal IPv4 network, as routing using GRE follows the same routing that IPv4 uses natively.”
