Network Solutions (Lan & Wan Integration)

Rameshwer Infotech has an experience of successfully network more than 500 nodes in LANs using Layer 3 and Layer 2 switching technologies on Copper and Fiber media. Our expertise of undertaking large Campus / Building LANs by integrating computer hardware, software, peripherals and internet services on Gigaspeed copper and fiber media has enabled us to plan, deploy and maintain such huge Campus LANs with Zero Defect Network Infrastructure.

In addition to building secure, high performance LANs, Krishan Infotech is dedicated to adapting your LAN and WAN to change. As a leading systems integrator, we design and build multi service WANs that consolidate disparate voice and data networks into a single, cost-effective networking infrastructure, supporting voice, video and data traffic.

The inherent characteristics of a multi service infrastructure are high performance, resilience and flexibility. As well as minimizing WAN communications and operational costs, a single full-service network allows you to take advantage of IP-enabled business applications for enhanced employee productivity, personalized customer experience and flexible customer interaction.

A large campus with groups of buildings can also use WAN technology to connect the buildings. Although the wiring and protocols of a campus might be based on WAN technology, they do not share the WAN constraint of the high cost of bandwidth. After the wire is installed, bandwidth is inexpensive because the company owns the wires and there is no recurring cost to a service provider. However, upgrading the physical wiring can be expensive.

Consequently, network designers generally deploy a campus design optimized for the fastest functional architecture that runs on the existing physical wire. They might also upgrade wiring to meet the requirements of emerging applications. For example, higher-speed technologies—such as Fast Ethernet, Gigabit Ethernet, and ATM as a backbone architecture—and Layer 2 switching provide dedicated bandwidth to the desktop.


Trends in Campus Design

In the past, network designers had only a limited number of hardware "optionsrouters or hubs" when purchasing a technology for their campus networks. Consequently, it was rare to make a hardware design mistake. Hubs were for wiring closets, and routers were for the data-center or main telecommunications operations.

Recently, local-area networking has been revolutionized by the exploding use of LAN switching at Layer 2 (the data link layer) to increase performance and to provide more bandwidth to meet new data networking applications. LAN switches provide this performance benefit by increasing bandwidth and throughput for workgroups and local servers. Network designers are deploying LAN switches out toward the network's edge in wiring closets. These switches are usually installed to replace shared concentrator hubs and give higher-bandwidth connections to the end user.


Example of Trends in Campus Design

Layer 3 networking is required in the network to interconnect the switched workgroups and to provide services that include security, quality of service (QoS), and traffic management. Routing integrates these switched networks, and provides the security, stability, and control needed to build functional and scalable networks.

Traditionally, Layer 2 switching has been provided by LAN switches, and Layer 3 networking has been provided by routers. Increasingly, these two networking functions are being integrated into common platforms. Multi layer switches that provide Layer 2 and 3 functionality, for example, are now appearing in the marketplace.

With the advent of such technologies as Layer 3 switching, LAN switching, and virtual LANs (VLANs), building campus networks is becoming more complex than in the past. Table 1-1 summarizes the various LAN technologies required to build successful campus networks. Cisco Systems offers product solutions in all these technologies.

Wireless Technology, The increased use of laptop computers within businesses, along with growth in employee mobility, has fueled the demand for wireless networks. Wireless LANs improve employee productivity because they allow for more flexibility.

Wireless LANs enable users to establish and maintain network connection throughout or between buildings without the limitations of cables or wires. Up until recently wireless networking was not widely adopted, but due to the maturing of international standards and the deployment of lightweight wireless networking hardware across a broad market section, wireless networking has finally come of age.

First and foremost Wireless LANs offer users mobility which supports productivity and service opportunities not possible with wired networks - wireless users have access to shared information without looking for a place to plug in. Wireless installation is also fast, simple and cost-effective, avoiding the need to physically move wires and cables around buildings.

Krishan Infotech designs and builds wireless solutions with your specific needs in mind. Whether you require fast, reliable, low-cost, individual connection to the LAN or a fully implemented wireless network for your business, our team is on the pulse of the latest technology developments. We apply this knowledge to your network to formulate best-in-class wireless solutions that will enhance your networking environment and improve your bottom-line.
