DRONA ARCHITECTURE

DRONA is the personal wide area network of DRDO and no other company nor any one else has the right to use the services provided by DRONA wide area network.

Dnet is a 100 Mbps gigabit fibre opical local area network connecting all the buildings and technology work Centres.

With more than 40 in house developed online application and fifity knowledge portals.

A seperate fully secured connectivity is also available in DRDL ON 24X7 basis , More than 100 nodes are provided all across the lab through a 2Mbps leased line connection.

DETAILS

• RACK SERVERA rack server is a type of hardware that provides the ability to install more than one server within a single rack-mount server chassis or casing.

Rackmount servers collectively host, execute and manage an enterprise application or serve as a data center. Designed to save physical floor space and other server resources, a rackmount server is typically housed with a horizontal rack chassis that can simultaneously hold multiple servers placed above each other.

•BLADE SERVER

A blade server is a stripped down server computer with a modular design optimized to minimize the use of physical space and energy. Whereas a standard rack-mount server can function with (at least) a power cord and network cable, blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. A blade enclosure, which can hold multiple blade servers, provides services such as power, cooling and networking.

•storage area network

• A storage area network (SAN) is a dedicated network that provides access to consolidated, block level data storage. SANs are primarily used to enhance storage devices, such as disk arrays, tape libraries.

• accessible to servers so that the devices appear like locally attached devices to the operating system.

• A SAN typically has its own network of storage devices that are generally not accessible through the local area network (LAN) by other devices.

• A SAN does not provide file abstraction, only block-level operations. However, file systems built on top of SANs do provide file-level access, and are known as SAN filesystems or shared disk file systems.Operating systems maintain their own file systems on their own dedicated, non-shared LUNs, as though they were local to themselves.

•switches• A network switch is a computer networking device that

connects devices together on a computer network, by using a form of packet switching to forward data to the destination device. A network switch is considered more advanced than a (repeater) hub because a switch will only forward a message to one or multiple devices that need to receive it, rather than broadcasting the same message out of each of its ports.

Key features :High expandability for investment protection Premium security and integrated management Multilayer reliability Convergence-ready support Outstanding Quality of Service (QoS)

These Gigabit Ethernet switches deliver outstanding security, reliability, and multiservice support capabilities for robust switching at the edge or aggregation layer of large enterprise and campus networks, or in the core layer of SMB networks.

•DMZ intranet• In   computer security, a   DMZ   or   Demilitarized Zone is a

physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger and untrusted network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization'slocal area network (LAN); an external attacker only has direct access to equipment in the DMZ, rather than any other part of the network.

•ISG firewall

The Juniper Networks Integrated Security Gateways (ISG) are purpose-built, security solutions that leverage a fourth generation security ASIC, the GigaScreen3, along with high-speed microprocessors to deliver unmatched firewall and VPN performance.

The Juniper Networks ISG 1000 is ideally suited for securing enterprise, carrier and data center environments.

The ISG 1000 enables secure, reliable connectivity along with network and application-level protection for critical, high-traffic network segments.

The Juniper Networks ISG1000 and ISG2000 Integrated Security Gateways are fully integrated firewall/VPN systems that offer multi-gigabit performance, modular architecture and rich virtualization capabilities.

•router

Router is a compact, high-performance router designed in a 4-slot form factor for deployment at the network edge, where robust performance and IP/Multiprotocol Label Switching (MPLS) services are necessary to meet the requirements of both enterprises and service providers. It enables Carrier Ethernet service providers to deploy an advanced network infrastructure that supports a range of IP video and triple-play (voice, video, and data) system applications in both the residential and business services markets. The Cisco 7604 also delivers WAN and metropolitan-area network (MAN) networking solutions at the enterprise edge.

•bulk encryptor unitBulk Encryptor is a powerful, networkattached encryption device designed for broadcast and on-demand applications in systems that use MPEG transport over UDP, IP, and Ethernet. The Netcrypt Bulk Encryptor has a maximum throughput of four gigabits per second (4 Gbps) in a compact, two rack-unit high chassis. It is capable of encrypting as many as 4,000 input programs into a maximum of 4,000 transport streams suitable for distribution as digital broadcast or as IP multicast sessions.

•media converterFibre Channel over Ethernet (FCoE) is a computer network technology that encapsulates Fibre Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks (or higher speeds) while preserving the Fibre Channel protocol.FCoE maps Fibre Channel directly over Ethernet while being independent of the Ethernet forwarding scheme. The FCoE protocol specification replaces the FC0 and FC1 layers of the Fibre Channel stack with Ethernet

CONCLUSION

So this was all about DRONA architecture as well as its network components .

Through this project we have learned about various computer networks protocol their interfacing with diffrent computer networking devices and how to control them .

More over we got to know about the software installation and configuration of various servers on system, data transfer done using DRONA architecture as a WAN (wide area network).
