Juniper MX Series

Juniper MX Chassis

Figure 1-6. Juniper MX family

Ranging from 2U to 44U, the MX comes in many shapes and configurations. From left to right: MX80, MX240, MX480, MX960, and MX2020. The MX240 and higher models have chassis that house all components such as line cards, routing engines, and switching fabrics. The MX80 and below are considered midrange and only accept interface modules.

Table 1-2. Juniper MX Series capacity (Based on current hardware)

Model	DPC Capacity	MPC Capacity
MX80	N/A	80 Gbps
MX240	240 Gbps	1.280 Tbps
MX480	480 Gbps	3.84 Tbps
MX960	960 Gbps	7.68 Tbps
MX2020	N/A	12.8 Tbps

Note

Please note that the DPC and MPC capacity is based on current hardware—4x10GE DPC and 32x10GE MPC—and is subject to change in the future as new hardware is released. This information only serves as an example.

The MX960 can accept up to 12 DPC line cards; using the 4x10GE DPC in the Table 1-2 calculations, you can come up with the following calculation:

40 Gbps * 2 (full-duplex) * 12 (maximum number of line cards on the MX960) = 960 Gbps.

Using the same calculation for the MPC capacity, the 32x10GE MPC line card can be used with the following calculation:

320 Gbps * 2 (full-duplex) * 12 (maximum number of line cards on the MX960) = 7.640 Tbps.

As the MX platform is upgraded with even faster switch fabrics and line cards, these calculations will change.
