Variety of network applications to deploy Gigabit Campus Network Planning Analys

Campus network is a platform for carrying a variety of network applications. As the digital campus, network applications such as further development of teaching, and web-based video and other high-volume rapid development of network applications, a number of servers already widely used in gigabit network card, which makes the campus network backbone upgrade to a pressing Gigabit needs.

  Here we follow the structure, performance, access, IP and application of five in terms of how to deploy Gigabit Campus Network.

Campus Network Structure Analysis Gigabit switches in the core layer can greatly improve the ability of the core data exchange, and the entire campus network access points not only to ensure adequate bandwidth, but also has managed and secure network services, so as to allow the entire campus network maximize the function of the central nervous system the entire campus.

Concern is our mission network In the core layer, the core switch through the Gigabit Link Gigabit respectively, together with two layers on the connected Gigabit switch connected to constitute a Gigabit ring design, once the problems with one Gigabit link, the other one will once automatically enabled. The link design, adequate protection of a key regional network of stable and reliable.

Bandwidth demand in the larger pool of teaching site or library level deployment of Gigabit backbone switches, with multiple expansion slots required to meet future expansion needs and to achieve Gigabit line card, wire-speed forwarding. Convergence layer of the other places will have to deploy gigabit switches. In addition, the network equipment needed to support hardware, IPv6, for the future to prepare a smooth transition.

In the access layer, network security intelligent access switch all the access switches used to provide strong security features, so common in the access layer for protection of viruses and attacks.

Campus Network Performance Analysis High-performance Gigabit network

first need to be protected in the core layer, therefore, the advanced nature of the core switch, throughput and reliability of the campus network and one of the most important aspects. Gigabit core switch at least support 3.2Tbps backplane capacity, and has a 1190Mbps over the packet forwarding capability, but also by the second generation of Crossbar architecture to overcome the first-generation Crossbar architecture to technical limitations, to achieve the quality upgrading . Concerned about the network is our mission

In addition, the core switches need to use ACL (access control) to implement virus protection, security filtering. ACL implementation on the core switches, the need to use the hardware ASIC chips, to ensure safety at the same time does not affect the purpose of network performance, while achieving the port-level machine data synchronization ACL / QOS. Through the line card chip L2/L3 wire-speed forwarding / multicast data from a port line card to fully distributed hardware design, divert, ease the load on line card ASIC chip, the pressure switches greatly enhance the overall data processing capability to meet the business needs of rapid growth and maintain the network high-performance non-blocking switching and network security, data, multi-service multi wire-line treatment.

In reliability, the core equipment needed power redundancy, redundant switching engines, also features hot-swappable module requires in order to prevent device-level single point of failure.

Campus network access authentication of

Ago when the campus network design standpoint is to make accessible to each user can access to the network to the same time, minimize the failure rate. Now, to ensure barrier-free access at the same time, pay more attention to the campus network access user authentication, unauthorized network access and access to be prohibited. Currently, to achieve certification function, the most commonly used is the 802.1X technology, and previously commonly used WebPortal or PPPoE authentication, has gradually been eliminated.
