WARPLINK REFERENCE DESIGN PLATFORM OVERVIEW
Architectural Overview
Mesh and Fabric
The WarpLink Reference Design Platform consists of a 9U 19" Compact PCI chassis with eight double-height slots. The slots accept three
types of cards: the Line Card, the Switch Card, and the Test Card. WarpLink devices on the cards are connected to one another through the
backplane interconnect, which supports both mesh and fabric switching schemes.
For the mesh-switching scheme, each slot has eight mesh ports. The mesh channels in the backplane connect seven mesh ports per slot to
a mesh port on each of the other seven slots. The one remaining unconnected port is looped back to itself. The connection is done such
that slot-
m
, port-
n
is connected to slot-
n
, port-
m
. Figure 1
and Figure 2 illustrate the mesh interconnects of the backplane for slot 1 and 2,
respectively. In this scheme, 2.5 gigabits of link data can go directly from any slot to any other slot.

Figure 2. Mesh Interconnects from Slot 2
In the fabric-switching scheme, each slot has eight line ports: four primary, four redundant. Slots 7 and 8 each have 32 fabric ports in
addition to the line ports. The fabric channels of the backplane connect the four primary line ports of every slot to four of the 32 fabric ports
on slot 8. The four redundant line ports of every slot are connected to four of the 32 fabric ports on slot 7. Figure 3
shows the fabric
interconnects of the backplane. In this scheme, 10 gigabits of link data can go from any slot to any other slot through slots 7 or 8. Data
links going through slot 8 are primary and those through slot 7 are redundant.
