The most important function of a three-layer switch is to speed up the fast forwarding of data within a large local area network, otherwise, it will go back to second place and serve as an interconnection between users and the same server.
At present, network users have increasingly high requirements for device performance, which has become a driving force for the rapid development of layer 3 switches, meeting more of users' other needs. With the acceleration of industry informatization and small and medium-sized enterprise informatization, the hotspot of network construction is shifting from the core of the network to the edge.
The shift of network construction towards access and application has brought a "golden" opportunity for the enterprise switchmarket. As many manufacturers push network intelligence to the edge and gradually expand into the market, the switch market is receiving attention and favor from various network equipment lords and is expected to become another battleground in the IT field.
At present, the commanding point of this battle is the third-layer switch market, especially the edge switch. Market research shows that edge switches have begun to surpass the core Ruijie switchand gradually occupy the mainstream position. The survey results on user needs also prove this point: when users choose enterprise network switches, the most important purchasing factors they consider are application and security. Therefore, most of them choose three-layer or multi-layer switches with strong manageability.
With the rapid development of the Internet/Intranet and the widespread application of B/S (browser/server) computing mode, the number of cross-regional and cross-network services is rapidly increasing, and the industry and users deeply feel the bottleneck effect of traditional routers in the network. Therefore, improving traditional routing technology is urgent.
