Apposite – NetropyVE Network Emulation Software

מאפיינים מרכזיים

Introducing Netropy Virtual Edition (VE), the Best Virtual Network Emulation and Testing Software

The NetropyVE network emulation software works on leading hypervisors VMware vSphere and KVM.

Assign a unique WAN access profile to every instance and mimic expected bandwidth limits, latency, loss, and other network conditions to see how well applications perform.

Emulate Any Complex Network Scenario in the Cloud

  • Scalability: Route multiple VMs through a single NetropyVE instance.
  • Packet Filtering: Assign packets to different links by IP address, VLAN, or any other packet identifier.
  • Bandwidths up to 1 Gbps: Precisely emulate links up to 1 Gbps.
  • Latency up to 20 sec.: Emulate network delay and jitter of 10 seconds or more in each direction, in increments of 0.01 ms.
  • Loss and Corruption: Set random, burst, or periodic packet loss to test the effects of corruption on voice and video applications.
  • Capture and Replay: Record the delay and loss characteristics of a production network as they vary second-by-second and replay them through the NetropyVE virtual network emulator.
  • Background Utilization: Complex network emulation software allows for testing how applications perform over a congested network with the background utilization and PCAP replay features.
  • Traffic Monitoring: View and download up to 24 hours of throughput graphs and link statistics.
  • Automation: Automate testing with the comprehensive command line interface (CLI).
  • Cost-effective: Get the functionality and performance you need at a price you can afford.
  • Requirements: NetropyVE requires EXSI 5.5 and above, 2 VCPUs, and 8 Gigabytes of ram. The virtual machine itself only takes up 1G of hard drive space.
