existing infrastructure investments. Today's workers are placing higher demands on networks,
running multiple, concurrent applications. For example, a worker joins a team conference call
through an IP videoconference, sends a 10-MB spreadsheet to meeting participants, broadcasts
the latest marketing video for the team to evaluate, and queries the customer-relationship-
management database for the latest real-time feedback. Meanwhile, a multigigabyte system
backup starts in the background and the latest virus updates are delivered to the client. The Cisco
Catalyst 3560 provides a means to intelligently scale the network beyond 100 Mbps over existing
Category 5 copper cabling and simultaneously support PoE for maximum productivity and
investment protection.
Intelligence in the Network
Networks of today are evolving to address four new developments at the network edge:
Increase in desktop computing power
●
Introduction of bandwidth-intensive applications
●
Expansion of highly sensitive data on the network
●
Presence of multiple device types, such as IP phones, WLAN access points, and IP video
●
cameras
These new demands are contending for resources with many existing mission-critical applications.
As a result, IT professionals must view the edge of the network as critical to effectively manage the
delivery of information and applications.
As companies increasingly rely on networks as the strategic business infrastructure, it is more
important than ever to help ensure their high availability, security, scalability, and control. By
adding Cisco intelligent functions for LAN access, customers can now deploy networkwide
intelligent services that consistently address these requirements from the desktop to the core and
through the WAN.
With Cisco Catalyst Intelligent Ethernet switches, Cisco Systems
realize the full benefits of adding intelligent services into their networks. Deployment of capabilities
that make the network infrastructure highly available to accommodate time-critical needs, scalable
to accommodate growth, secure enough to protect confidential information, and capable of
differentiating and controlling traffic flows is critical to further optimizing network operations.
Cisco EnergyWise Technology
Cisco EnergyWise is an innovative architecture, added to the Cisco Catalyst 3560 switches,
promoting companywide sustainability by reducing energy consumption across an entire corporate
infrastructure and affecting more than 50 percent of global greenhouse gas emissions created by
worldwide building infrastructure, a much greater effect than the 2 percent generated by the IT
industry. Cisco EnergyWise enables companies to measure the power consumption of network
infrastructure and network-attached devices and manage power consumption with specific
policies, reducing power consumption to realize increased cost savings, potentially affecting any
powered device.
EnergyWise encompasses a highly intelligent network based approach to communicate messages
that measure and control energy between network devices and endpoints. The network discovers
Cisco EnergyWise manageable devices, monitors their power consumption, and takes action
based on business rules to reduce power consumption. EnergyWise uses a unique domain-
naming system to query and summarize information from large sets of devices, making it simpler
