Chapter 4 Networking Applications

The high-capacity, Layer 2/3 S7500 Series Ethernet Switches are mainly designed for
IP MANs, large-sized enterprise networks and campus networks. They can serve as
aggregation switches to play important role in MANs, or serve as core switches in
enterprise
S3100/S3600/S5600/S9500
management system, allows for comprehensive solutions for MAN and enterprise
networking.
The following sections describe several typical networking applications of the S7500
series.

4.1 Application in a MAN

Typically, an S7500 series switch can be used at the aggregation layer in a MAN. In
upstream direction, the switch is connected to a Layer 3 switch (for example, a H3C
S9500 series routing switch) or a GSR (Gigabit switching router) in the backbone
network through a GE link across long/ultra-long haul dark fiber cable (you can also use
multi-GE Trunk to increase upstream bandwidth). In downstream direction, the switch is
connected to the egress Layer 2/3 Ethernet switches (for example, H3C
S3100/3600/S7500 series switches) in LANs through GE ports across long/ultra-long
haul dark fiber cables (you can also use multi-GE Trunk to increase downstream
bandwidth).
