Although many nations are now involved with the Internet in one way or another, this paper focuses on the primary role the U. Very little of the current Internet is owned, operated, or even controlled by governmental bodies.
The Internet indirectly receives government support through federally funded academic facilities that provide some network-related services.
Increasingly, however, the provision of Internet communication services, regardless of use, is being handled by commercial firms on a profit-making basis. This situation raises the question of the proper long-term role for government in the continued evolution of the Internet.
Is the Internet now in a form where government involvement should cease entirely, leaving private-sector interests to determine its future?
KAHN government still have an important role to play? This paper con- cludes that government can still make a series of important contribu- tions. Indeed, there are a few areas in which government involve- ment will be vital to the long-term well-being of the Internet. Extensions of the packet-switching con- cept to satellite networks and to ground-based mobile radio networks were also under development by ARPA, and segments of industry notably not the traditional telecommunications sector were show- ing great interest in providing commercial packet network services.
It seemed likely that at least three or four distinct computer networks would exist by the mids and that the ability to communicate among these networks would be highly desirable if not essential. In a well-known joint effort that took place aroundRobert Kahn, then at ARPA, and Vinton Cerf, then at Stanford, collaborated on the design of an internetwork architecture that would allow packet networks of different kinds to interconnect and machines to commu- nicate across the set of interconnected networks.
The period from to saw four successively refined versions of the protocol implemented and tested by ARPA research contractors in academia and industry, with version number four even- tually becoming standardized.
The initial satellite Earth stations were in the United States and the United Kingdom, but subsequently additional Earth stations were activated in Norway, Germany, and Italy.
At the time, no personal computers, workstations, or local area networks were available commercially, and the machines involved were mainly large-scale scientific time-sharing systems.
Remote access to time-sharing systems was made available by terminal ac- cess servers. These were both engineering-intensive tasks that took considerable expertise to ac- complish.
Before this, these capabilities were unavailable; they had to be handcrafted by the engineers at each site.

The establishment of the ICCB was important because it brought a wider segment of the research com- munity into the Internet decision-making process, which until then had been the almost-exclusive bailiwick of ARPA. During this early period, the U.
The government also maintained responsibility for overall policy. In the mid- to late s, experimental local area networks and experimental workstations, which had been developed in the research community, were connected to the Internet according to the level of engineering expertise at each site.
In the early s, Internet-compatible commercial workstations and local area networks became available, significantly easing the task of getting connected to the Internet. KAHN of lists of hosts and their addresses on the network.
Other govern- ment-funded groups monitored and maintained the key gateways be- tween the Internet networks in addition to supporting the networks themselves. Inthe U. By the early s, it was clear that the internetwork architecture that ARPA had created was a viable technology for wider use in defense.
In fact, these gate- ways were designed to limit the interactions between the two net- works to the exchange of electronic mail, a further safety feature. By the early s, the ARPA Internet was known simply as the Internet, and the number of connections to it continued to grow.
Recognizing the importance of networking to the larger computer science community, the National Science Foundation NSF began supporting CSNET, which connected a select group of computer science researchers to the emerging Internet.
CSNET also provided the capacity to support dial-up e-mail connec- tions. In addition, access to the ARPANET was informally extended to researchers at numerous sites, thus helping to further spread the networking technology within the scientific community. Although it was the only one that dealt explicitly with internetworking of packet networks, its use was not yet mandated on the ARPANET.
At the same time, it led to a rethinking of the process that ARPA was using to manage the evolution of the network. By the mids, however, network connectivity had be- come sufficiently central to the workings of the computer science community that NSF became interested in broadening the use of networking to other scientific disciplines.They built a DDoS attack mitigation solution on the high-speed NewSQL database VoltDB to have the capability to analyze 48, IP packets per second, allowing them to see in real time which sites.

This scrappy "do things that don't scale" approach worked. Packet Subsystem - Allows applications to listen for data packets received from network devices and to emit data packets out onto the network via one or more network devices. The following figure illustrates the various subsystems that are part of ONOS today and a few that are planned in the near future.
The Union Pacific Railroad was thus commissioned by Congress to thrust westward from Omaha, Nebraska; for each mile of track constructed, the company was granted 20 square miles of land and a generous federal loan ranging from $16, to $48, A group of security engineers addressed those shortcomings with a new kind of firewall built from the ground up.
Sometimes, the problems we experience with computers are a result of a legacy design. - History of Computers When you think about the origins of the electronic digital computer, what scientists’ names come to mind.
Many historians give the credit to the American scientists J. Presper Eckert and John W. Mauchy. They built their Electronic Numerical Integrator and Computer (ENIAC) during World War II.
