Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). Ethernet hubs and/or switches to reduce installation costs, increase reliability, and enable point-to-point management and troubleshooting.

Today, most corporate networks are faced with a number of challenges.

•  A driving need for new applications to increase productivity, business efficiency and improve customer service.
  
  
•  Emerging applications (such as voice over IP (VoIP) and video conference) requiring changes to the current network infrastructure.
  
  
•  The increased use of wireless connectivity brings about security issues that need to be addressed.
  

To be specific, network administrators must address complex network issues and, at the same time, keep an eye to protect the network. As businesses become more global, employees are no longer bound to the desk. Work mobility with multimedia and remote tele-conferencing technologies are in demand. Thus network administrators are concerned with the following problems.

How to maintain a network with high availability?

•  Real-time network security ( access authentication, authorization and accounting)
  
  
•  Minimum network down time (redundancy and resilient capabilities)
  
  
•  Efficient network management (easy configuration, troubleshooting and monitoring)
  

How to deploy a network that supports a variety of applications (video, voice, and data)?

•  High throughput
  
  
•  Premium QoS (Quality of Service)
  

Thus, there is a need for cost-effective, high performance, resilient networks with built-in scalability. In summary, organizations require cost effective - Lower TCO, highly available, scalable solutions to satisfy need of Organizations and Company.
