vJunosEvolved Architecture

The vJunosEvolved is a single VM solution where the Junos OS Evolved Routing Engine (RE), Packet Forwarding Engine (PFE) and vBT-COSIM run on the same VM. KVM is the hypervisor used to deploy Junos OS Evolved Linux VM.

When vJunosEvolved instance boots up, the vBT-COSIM simulation is also initialized along with Routing Engine and Packet Forwarding Engine (PFE).

vJunosEvolved can support up to 2000 pps of throughput (as per vBT-COSIM’s specifications) using 4 cores and 8GB memory. Any additional cores and memory configured are allocated to the Junos OS Evolved Routing Engine. For the anticipated lab use cases, 4 cores and 8GB memory is sufficient.
