Chapter 4 Networking Applications

You can deploy S3900 series on many types of networks, such as enterprise networks
and broadband access networks. Following are several typical networking applications.
4.1 Broadband Ethernet Access for Residential Communities
On the broadband access network of a residential community, an S3900 series switch
is located in the center. It is downlinked to S2000 or S3026 series switches to reach the
Ethernet users and uplinked to a core Layer 3 switch through a GE extension module to
connect to the MAN backbone.

4.2 Application for Connecting Branches or Small- to
Medium-Sized Enterprises
For small-to medium-sized enterprises or branches of a large enterprise, S3900 series
switches can server as the backbone switches on their networks and can be connected
to the headquarters or other branches through routers. As the enterprise size increases,
the network also can expand by subtending the S3900 series.
