Layer 3 Switching: Re-Inventing the Router
Overview Today we find that shared LANs are not fast enough, servers have been consolidated into data centers, WAN speeds are increasing, voice and data networks are converging, and scalability has become an issue with the expanding PC population. Network availability is a critical success factor for mission-critical business systems, especially when they combine public and private networks. To respond to these many pressures, new technologies,have been introduced for high-speed LAN interconnection. This is resulting in serious confusion among potential buyers.Terms such as Layer 3 switching, multilayer switching, routing switches, switching routers, and gigabit switches regularly appear in the trade press, implying both a lack of standards and the inevitability of severe compatibility problems.This white paper describes the key functions and characteristics of a switched internetwork, clarifies what layer 3 switching is and is not, and demonstrates why routing will continue to be a part of future networks. The relationships among switching, route processing, management, and intelligent network services will also be analyzed.
