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 or campus networks. This series, together with the H3C
S3100/S3600/S5600/S9500 series and Huawei's MA5200 Ethernet access
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).
