ES2 4G LM
Not applicable
First supported: 7.0.1
176 W maximum
Acts as frame forwarding engines for the physical interfaces
Responsible for processing data traffic
Pairs with IOAs to process data from different types of network connections
FFA ASIC
Supports a line rate of 128–byte packets on IOAs
The 100–Gbps switch fabric allocates 3.4 Gbps of overall bandwidth to each regular
line module slot and 10 Gbps of overall bandwidth to each of the turbo slots (slot
2 and slot 4).
The 320–Gbps switch fabric allocates 10 Gbps of overall bandwidth to each line
module slot. The line interface on the ES2 4G LM when installed in a 320 Gbps
fabric configuration is 3.9 Gbps; you can achieve this rate with random packet sizes
in the range 64–1518 bytes or a mixture of packet sizes that represent Internet mix
traffic (IMIX).
See JunosE System Basics Configuration Guide, Chapter 6, Managing Modules for
more information.
