WAN With Internet Access
Larger organizations with more users trying to access the Internet often require a dedicated connection with more bandwidth to their internet service provider (ISP). ISPs typically offer some combination of dial-up and dedicated access, so they can adequately support different customerís needs. The solution featured here offers a means for providing dedicated Internet access to medium-sized business LANs. Most organizations will accomplish this through a digital leased line, as illustrated on the left. A T1 line provides a full 1.544 Mbps of bandwidth for fast downloads of graphics and images across the link. Since Cisco owns approximately 50% of the WAN router market, most ISPs will use Cisco router. Customers connecting to ISPs can also use a Cisco router, or, as shown here, can use other manufacturersí routers that support Point-to-Point Protocol (PPP) for interoperability. The wireless Internet access method illustrated on the right side of this solution is somewhat more unusual that a leased-line connection but can result in significant cost savings for customers located near their ISP's office. A wireless Ethernet bridge at the customersí site connects via spread-sprectrum radio to a wireless access point on the ISP's network, providing 3 Mbps of bandwidthómore than T1óand eliminating the need to pay monthly line costs. A software based firewall system protects the customerís internal network from unauthorized intrusion via the internet.
