SOHO and Enterprise Networks
SOHO Network
A small office home office (SOHO) LAN is a business-oriented network possibly using a centralized server, in addition to client devices and printers, but often using a single networking appliance to provide LAN and Internet connectivity.
- often referred to as a “SOHO router,” “Internet router,” or “broadband router”
Enterprise Network
- Networks supporting larger businesses or academic institutions have networking appliances with the same basic functions as a SOHO router, but because they must support more clients with a greater degree of reliability
- each function is performed by a separate network device
The following graphic illustrates how an enterprise LAN might be implemented:
- Each segment of the network is designed as a modular function
- Client computers and printers are located in work areas and connected to the network by cabling running through wall conduit
- Laptops and mobile devices connect to the network via wireless access points (APs)
- Network servers are separated from client computers in a server room
- Workgroup switches connect each of these blocks to core/distribution switches, routers, and firewalls
- These network appliances allow authorized connections between the clients and servers
- Internet services are placed in protected screened subnets, which represent a border between the private LAN and the public Internet
- Traffic to and from this zone is strictly filtered and monitored
- Network border services provide Internet access for employees, email and communications, remote access and WAN branch office links via virtual private networks (VPNs), and web services for external clients and customers
