Cisco is expected to make much bigger and more dramatic moves into software in 2008 as it fleshes out its strategy to make the network the key enabling platform for all IT operations.
Unified communications, collaboration, Web 2.0 and data center virtualization will continue to drive the company’s momentum in the new year as Cisco seeks to add more software and service capabilities to network infrastructure that heretofore have resided on high-end computers, servers, storage devices, PCs and special-purpose computing applications. To that end, Cisco will compete more heavily with entrenched IT systems vendors and partners such as IBM, Microsoft, HP and EMC.

VLAN??a href=”http://www.pass4sure.com/cisco-index.html”>Virtual LAN
As the network is gaining in popularity, the demand on the network in some enterprises is increasing sharply, and the scare of their internal corporate networks become larger and larger. Along with this situation the attendant security, network performance problems are the troubles for network administrators. However, VLAN technology, has solved the series of problems.
Firstly??t the first, people used HUB to linkmany clients to the network, and the HUB provided a public cable for the clients, as more and more users were accessed to the network, the broad band for each user was scale-down. For example : To link 10 HUB users with 10M Ethernet, then each user has to share bandwidth 10M/10-1M. Obviously, the way with sharing hub has been unable to meet the increasing demand for surge of network scale.People began to use switches to replace the hub. Switches access each user to provide a dedicated data channel, which is no longer similar to the HUB as a whole to share bandwidth.Although the bandwidth solved the distribution problem, but as more and more users access the network, people have found a new problem: Any arbitrary news will be broadcasting for all users in the network, the greater the size of network, the greater broadcasting on the scope, the performance of the entire network has become so intolerable to the customers because of broadcasting.At this time, network administrators use the router (which can be isolated broadcasting domain) to divide the bloated network into a number of smaller networks, the problem seems to have been resolved, but because the router only has few interface links to up the expense, so make the sub-tasks to the high cost on this network.
The switch has a number of interfaces, and transmit the data faster, but could not prevent the spread of the broadcasting;
