Operation Manual – Product OverviewH3C S3100 Series Ethernet Switches Chapter 4 Network Design4-1Chapter 4 Network DesignThe S3100 series can be flexibly deployed in networks. They can be used in enterprisenetworks, or serve as broadband access points. The following examples are threetypical networks using the S3100 series.4.1 MAN Access SolutionIn a metropolitan area network (MAN), the S3100 series can serve as access devices.In the downlink direction, they directly connect to users through 100 Mbps interfaces;and in the uplink direction, they connect to an aggregation layer (Layer 3) switches orMA5200 intelligent service gateways, which further connect to the core of the MANthrough routers. This provides you a comprehensive gigabit-to-backbone100-Mbps-to-desktop MAN solution.Figure 4-1 Network diagram for a MAN using S3100 series4.2 Education Network SolutionIn a campus network, the S3100 series can serve as desktop switching devices at theaccess layer. They directly connect to users in education buildings through 100 Mbpsdownlink interfaces; and connect to the core switch in the campus through a 1000 Mbpsuplink interface; the core switch further connects to the education network through a
