As we all know, home routers are different from enterprise routers. Enterprise routers have higher requirements and better performance. Do you know what should be paid attention to when choosing an enterprise router? Now let's have a look!

  1. Performance and redundancy, stability

   the working efficiency of the router determines the performance, as well as the amount of data and applications loaded at runtime. The router has two routing modes: software and hardware transmission. The software mode generally adopts centralized routing, and the hardware transmission can be divided into centralized and distributed hardware transmission. The latter is the representative of the next generation network. The hardware transmission mode can effectively improve the delay in data transmission and improve the network performance. The software stability and hardware redundancy of routers must also be considered. The design of fully redundant routers can greatly improve the reliability of equipment in operation. At the same time, the stability of software system can also ensure the deployment of user applications.

   2. Interface

   bandwidth, continuity and compatibility should be considered in the construction of enterprise network. The interface type that a device can support at the same time should be considered in the core router interface. Including 100M / Gigabit Ethernet, ATM interface and high-speed POS interface of various copper core cables and optical fiber interfaces.

  3. Number of ports

  to select a suitable router, you must consider the number of ports to be routed. There are many options in the market, from a few ports to hundreds of ports. Users need to consider many aspects, including actual demand and future demand expansion. Generally speaking, for small and medium-sized enterprises, dozens of ports can usually meet the needs of enterprises. What really matters is the choice of port number for large enterprises. Statistics are usually made according to the number of network segments to predict the future development potential of the enterprise network, and then select. You can choose from dozens to hundreds of ports according to your needs.

   4. Standard protocols and features supported by routers

   when selecting a router, you must consider various open standard protocols supported by the router. Open standard protocol is a good prerequisite for device interconnection. The supported protocols provide flexibility and efficiency in design. For example, check whether the complete multicast routing protocol, MPLS and VRRP are supported. Other companies also consider whether the router supports IPX and AppleTalk routing while performing normal IP routing. In order to improve the routing efficiency, some equipment manufacturers are developing some special protocols. When users select these features, they should first clarify their own needs, and also pay attention to avoiding the use of such technologies in the core technologies. This is because nonstandard protocols mean that the products of different equipment manufacturers are incompatible, and users will be closed to a certain equipment manufacturer. In addition, non standardized protocols are often replaced by new open protocols.

   5. Difficulty in determining management methods

  router management is particularly important. At present, there are three mainstream configurations of routers. One is a fool router, which does not need to be configured. Its main user group is home or SOHO; Second, it is a router with the simplest web configuration interface. The main user groups are low-end SMEs. Because it is aimed at general non professionals, the configuration cannot be complex. The third way is to use the terminal to connect to the router port through a dedicated configuration line and configure it directly. The configuration file of the newly purchased router also has no content. After purchasing the router, the user must first use this method for basic configuration. Since the user group of the router is large enterprises and professional users, the configuration of the router is much more complex than that of the low-end router. The current high-end routers are configured in English command, which should be managed and configured by professionally trained experts.

   6. Security

   due to the prevalence of network hackers and viruses, the protection and defense capability of network devices is also one of the important factors in selecting routers. The router uses a large number of access control lists (ACLS) for shielding and isolation while using radius/tacacs and other authentication. Users should pay attention to ACL control when selecting routers. The CPU checking method will reduce the performance of the router, but the hardware implementation method will not bring additional burden to the work.
