In today's Internet architecture, the Internet Protocol (IP), Internet addresses, and the Domain Name Service (DNS) implement core Architectural principles that restrict the Internet’s ability to adapt to improved performance and reliability requirements. In the future Internet, the current edge of the network (e.g. user computers and mobile devices) will often be just one hop to the Internet. That is, devices will be able to connect directly into the Internet, eliminating barriers such as local networks, local network routers, and domain name servers. The trend to connect more devices will also accelerate, facilitated by the increasing installation of Internet Protocol version 6 (IPv6). In the future, the Internet will connect vast numbers of tiny devices integrated into cell phones and other mobile devices. These devices may challenge the traditional understanding of network topology as a collection of networks and, instead, view the future Internet as a single unified network.
According to Gokhale et al, in a process-based Web server architecture, the server consists of multiple single-threaded processes, each of which handles one request at a time. In a thread-based architecture, the Web server consists of a single multithreaded process; each thread handles one request at a time. However, there is another Web server model-the one I use. This model uses multiple executing servers, each processing user requests concurrently.
The proposed future Internet is comprised of the following capabilities:
· Rather than using local networks, such as Ethernet. Communication between user computers and Web servers and between mobile devices and Web servers would be direct via Internet routers.
· Devices would be assigned permanent IP addresses, issued by the Internet authority, thus eliminating the need for name-to-IP address translation, Thereby eliminating the need for Domain Name Systems. User computers and Mobile devices would access a Web server by providing a Universal Resource Locator (URL) (Web site address) to the Internet service provider (ISP). The ISP, In turn, would look up the Web server IP address in its directory and append it to the IP packet. In case the IP address has not been recorded in the ISP directory, the ISP would broadcast a request to obtain the IP address.
· In order to provide increased security of data, every user computer and mobile device would have its own [P address, requiring the replacement of Internet Protocol version 4 (IPv4) with IPv6, in order to provide for a large address space. IPv6 does not provide any better (or worse) support for quality of service than IPv4, but it does have several important features that would enhance the performance and security of the future Internet, including larger address space, integrated security capabilities, easier configuration, and a simplified packet header format.
· Reliability would be increased because there would be fewer components that could fail and fewer single points of failure (e.g., elimination of local networks and Domain Name Systems). This is important because the Domain Name System is reputedly one of the main causes of failure in the Internet.
· Cyber security would be increased because there would be fewer components that could be attacked and if attacks do occur, resolution would be simplified by pinpointing the location of an attack by virtue of using a much simpler Internet configuration than is presently the case.
