Factors to Consider in Choosing a Router
When selecting a router, we need to match the characteristics of the router to its purpose. Similar to the switch, cost and interface types and speeds must be considered as well. Additional factors for choosing a router include:
Expandability
Media
Operating System Features
Expandability
Networking devices, such as routers and switches, come in both fixed and modular physical configurations. Fixed configurations have a specific number and type of ports or interfaces. Modular devices have expansion slots that provide the flexibility to add new modules as requirements evolve. Most modular devices come with a basic number of fixed ports as well as expansion slots. Since routers can be used for connecting different numbers and types of networks, care must be taken to select the appropriate modules and interfaces for the specific media.
Operating System Features
Depending on the version of the operating system, the router can support certain features and services such as:
Security
Quality of Service (QoS)
Voice over IP (VoIP)
Routing multiple Layer 3 protocols
Special services such as Network Address Translation (NAT) and Dynamic Host Configuration Protocol (DHCP)
For the selection of devices, the budget is an important consideration. Routers can be expensive based on interfaces and features needed. Additional modules, such as fiber-optics, can increase the costs. The media used to connect to the router should be supported without needing to purchase additional modules. This can keep costs to a minimum.
