Figure 6-47. 3-SN CSS with High Inter-SN Traffic
Fiber Engineering for 3 SNs
Switches with 3 SNs are connected b y 1 to 7 fiber links to provide suffic ient
switching fabric at the CSS. The traffic in all locales within a single SN does not
require engineering. Only traffic that links from locales in 1 SN to another SN (and
vice versa) must be engine ered. The traffic that links across these fiber s is simply
the sum of the traffic that links to locales loc ated in the other SN.
