Information Technologies have increasingly been increasing, and networks are the means by which the world is moving and the Internet is the means to exploit these technologies. The internet is a giant network which allows users to move data back and forth no matter where, for owners of sites is really expensive to store all this information and maintain it, here comes into play mega datacenters that handle more and more the world of computing and storage needs, make the data-center networks will be increasingly important as the need for systems that allow the scalability of these large data managers is increasing, since generally the existing systems do not allow this growth and have a maximum point of administration.
A system that is in the process, which has a great future because it is designed with the objective of this can support to enable the scalability data centers, is "Portland", a system of algorithms and protocols that eliminate the constraints of scalability and path - in-routing of layer 2, and avoids the administrative problems caused by virtualization and deployment of network layer 3 in network environments datacenters. The data-center today, often at run on Layer 3 networks, but this requires large numbers of man-hours to configure and maintain these networks. These networks of layer 3, not allow a simple implementation of migration to virtual machines, limiting the flexibility and efforts to reduce energy costs in data-centers, as Portland if it meets this demand, enabling network operators to manage the datacenter as a single factory.
Portland's success is location discovery protocol which opens the possibility of a scalable Layer 2 network. The switches automatically learn its location within the topology of data-center without any human intervention. These switches assign then addresses' Pseudo MAC (PMAC) to all other servers that connect these directions PMAC, instead of MAC addresses, are used internally in the network for sending packets.
The behavior of servers remains the same while running on networks with Portland, where a server wants to talk to the server on the other side of data-center, the first server still sends a "ARP," which is the requisition of the MAC address the computer with which you want to communicate based on IP address. But now, instead of passing the requisition to the whole network, the switch that received the ARP communicates with a directory service which will address PMAC returns, instead of the traditional MAC address, then when new machines, simply generate new PMAC addresses, allowing the networks and the movement of data is growing as the scalable data centers can grow without any problem..
We know that the internet and the flow of data are increasingly growing, but this way of interacting with the network not only used by a PC, mobile technologies are rapid growth, and as such there is a need to exchange data as we do from our computer.
Mobile developers stop thinking of how to do to send voice, because although the text messaging and phone calls are not really the goal, are complementary, and statistics says this, where what more moves are means of a special phone multimedia data, but the bandwidths of these devices allow you to move large data quickly, so we think that new technologies bring embedded phones as wireless modems that enable supply this demand.
Finally, the networks are the means by which the world is moving, these dominate the planet, and must be thinking that they can grow more and more, and therefore need to think about scalable systems, and devices that can mobilize much data at a higher speed.
