CHAPTER 01

ABSTRACT:The goal of data-center networking is to interconnect a large number of server machines with low equipment cost while providing high network capacity and high bisection width. It is well understood that the current practice where servers are connected by a tree hierarchy of network switches cannot meet these requirements. In this paper, we explore a new server-interconnection structure. We observe that the commodity server machines used in todays data centers usually come with two built-in Ethernet ports, one for network connection and the other left for backup purposes. We believe that if both ports are actively used in network connections, we can build a scalable, cost-effective interconnection structure without either the expensive higher-level large switches or any additional hardware on servers. We have proven that FiConn is highly scalable to encompass hundreds of thousands of servers with low diameter and high bisection width. We have developed a low-overhead traffic-aware routing mechanism to improve effective link utilization based on dynamic traffic state. We have also proposed how to incrementally deploy FiConn.

PROJECT SCOPE:The goal of data-center networking is to interconnect a large number of server machines with low equipment cost while providing high network capacity and high bisection width. It is well understood that the current practice where servers are connected by a tree hierarchy of network switches cannot meet these requirements.

In this project, we explore a new server-interconnection structure. We observe that the commodity server machines used in todays data centers usually come with two built-in Ethernet ports, one for network connection and the other left for backup purposes.

PRODUCT FEATURES:We have also proposed how to incrementally deploy FiConn. FiConn a novel serverinterconnection network structure that utilizes the dual-port configuration existing in most commodity data-center server machines it is a highly scalable structure because the total number of servers it can support is not limited by the number of server ports or switch ports. It is cost-effective because it requires less number of switches and links than other recently proposed structures for data centers.

INTRODUCTION:DATA-CENTER networking designs both the network structure and associated protocols to interconnect thousands of or even hundreds of thousands of servers at a data center, with low equipment cost, high and balanced network capacity, and robustness to link/sever faults. Its operation is essential to offering both numerous online applications, e.g., search, gaming, Web mail, and infrastructure services. It is well understood that treebase solution in current practice cannot meet the requirements.

In this paper, First, it costs less to build a data-center network. We do not need high-end, expensive switches, which are widely used today. Standard, off shelf servers with two ports (one for operation in network connection, the other for backup) are also readily available. Second, the wiring becomes relatively easy since only two server ports are used for interconnection. We do not need to add additional hardware or wires on a server except the two NIC ports. Third, it may spawn more academic research into data centers. New problems and solutions in data-center networking, systems, and applications can be found, implemented, and assessed through an easy-to-build test bed at a university or institution. Today, data-center infrastructure may only be afforded by a few cash rich companies such as Microsoft, Google, and Yahoo.

Neither current practice nor recent proposals can solve our problem. The tree-based solution requires expensive, high-end switches at the top level of the tree in order to alleviate the bandwidth bottleneck. The scaling of the Fat-Tree solution is limited to the number of ports at a switch, and it also needs more switches. The fundamental problem is that, we need to design a new network structure that works for servers with node degree of only 2 in order to scale. We propose FiConn, a scalable solution that works with servers with two ports only and low-cost commodity switches. FiConn defines a recursive network structure in levels. A high-level FiConn is constructed by many lowlevel FiConns. When constructing a higher-level FiConn, the lower-level FiConns use half of their available backup ports for interconnections and form a mesh. This way, the number of servers in FiConn, , grows double-exponentially with FiConn levels.

CHAPTER 02 SYSTEM ANALYSIS: PROBLEM DEFINITION:Data-Center networking designs both the network structure and associated protocols to interconnect thousands of or even hundreds of thousands of servers at a data center, with low equipment cost, high and balanced network capacity, and robustness to link/sever faults.

EXISTING SYSTEM:Existing network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Unfortunately, even when deploying the highest-end IP

switches/routers, resulting topologies may only support 50% of the aggregate bandwidth available at the edge of the network, while still incurring tremendous cost. Non-uniform bandwidth among data center nodes complicates application design and limits overall system performance.

LIMITATIONS OF EXISTING SYSTEM:Ethernet switches to support the full aggregate bandwidth of clusters consisting of tens of thousands of elements. Similar to how clusters of commodity computers have largely replaced more specialized SMPs and MPPs, we argue that appropriately architected and interconnected commodity switches may deliver more performance at less cost than available.

PROPOSED SYSTEM: In this paper, we explore a new server-interconnection structure. We observe that the commodity server machines used in todays data centers usually come with two built-in Ethernet ports, one for network connection and the other left for backup purposes. We believe that if both ports are actively used in network connections, we can build a scalable, cost-effective interconnection structure without either the expensive higher-level large switches or any additional hardware on servers. We have proven that FiConn is highly scalable to encompass hundreds of thousands of servers with low diameter and high bisection width. We have developed a low-overhead traffic-aware routing mechanism to improve effective link utilization based on dynamic traffic state. We have also proposed how to incrementally deploy FiConn. FiConn a novel server-interconnection network structure that utilizes the dual-port configuration existing in most commodity data-center server machines it is a highly scalable structure because the total number of servers it can support is not limited by the number of server ports or switch ports. It is cost-effective because it requires less number of switches and links than other recently proposed structures for data centers.

ADVANTAGES OF PROPOSED SYSTEM:We compare FiConn with other recently proposed data-center networking structures in detail, disclosing that FiConn is advantageous over all other in terms of deploying cost, but holds high scalability with constant number of server ports and switch ports. we make three main contributions in FiConn. First, FiConn offers a novel network structure that is highly scalable with off-the-shelf servers of node degree 2 and low-end commodity switches while having low diameter and high bisection width. FiConn uses traffic-aware routing that exploits the available link capacities based on traffic dynamics and balances the usage of different links to improve the overall network throughput.

FEASIBILITY STUDY:

The feasibility of the project is analyzed in this phase and business proposal is put forth with a very general plan for the project and some cost estimates. During system analysis the feasibility study of the proposed system is to be carried out. This is to ensure that the proposed system is not a burden to the company. For feasibility analysis, some

understanding of the major requirements for the system is essential.

Three key considerations involved in the feasibility analysis are

ECONOMICAL FEASIBILITY

TECHNICAL FEASIBILITY SOCIAL FEASIBILITY

ECONOMICAL FEASIBILITY

This study is carried out to check the economic impact that the system will have on the organization. The amount of fund that the company can pour into the research and development of the system is limited. The expenditures must be justified. Thus the developed system as well within the budget and this was achieved because most of the technologies used are freely available. Only the customized products had to be purchased.
