Cisco IOS software is the internetworking brain for Cisco switches and routers. Releases are consistantly evolving, being modified and enhanced, and this creates multiple versions that are viable. Different releases contain different features to accomodate the level of complexity of the various networks. A Engineers chooses the correct version by number and types of routers or switches in his network, the nature of business that is performed over the network, and the applications the network is supporting. They have difficulty in choosing the correct IOS version because there are so many and the naming conventions are complex. This book is the ultimate guide to determine how to optimize migration to new IOS releases. This book provides background on the evolution of IOS and explains the logical structure of its naming conventions. Detailed table indicate the features, uses migration paths, strengths, for each release so that you can choose the perfect release for your network.
