Are you a good buyer for the routers? Optional(buy) elements of the routers

1, The features of the routers

The router is one of the most important HP MSR900 network interconnection devices, which work in the network layer, is used to interconnect different types of network,the router through the routing decision data forwarding, forwarding strategycalled: routing (routing), which is the origin of the router name (router,forward).

Connected and isolated network, different collision domains.

Selection of optimal transport path for data exchange. In the router keeps data -- the routing table associated with a transmission path (Routing Table).Routing table can be set up by the system administrator fixed (static routing table), can also be modified by the system dynamic (dynamic routing table).

The router also usually provides traffic monitoring, access control, firewall andpriority setting, data encryption, address translation, VLan management and other functions.

Although the router can be used for the interconnection between all kinds oflocal area network, however, is mainly used for the interconnection betweenrouters, LAN and WAN at the same time, often need to configure router.

2, How to buy a router

Usually at the time of purchase mainly should attente to the following questions:

(1) management mode: is that users can set the router management by what way.

Router basic management mode is using terminal (HyperTerminal or windows provided by the special configuration line) connected to the router configuration port configuration, users buy a router are generally carried outpreliminary settings for the router to use this way.

(2) multi protocol support: router support which Wan protocol.

The bureau uses different WAN technologies can provide Wan line of differentusers, and users often cannot ensure that it has been using a WAN line,therefore, we WAN protocol which supports the best buy router attention. At present, Wan line telecommunications bureau provides several X.25, frame relay, DDN line, ADSL, so choose the router best consider the actual needs ofthe future enterprise.

(3) the address translation function:

Using the router external connection or the Internet, routers can shieldcompany internal LAN network address conversion function, unified into wide area network address the telecommunication bureau provided by address, so the network external users will not be able to know the internal networkaddress, to prevent the illegal user ids. At the same time, this method also realizes the LAN users through an IP address to access HP MSR20 Internet resources.
