Avalanche 3.80 Features

(Cross-posted from Spirent Networks Blog)

On Friday November 4th, the latest General Availability build of Avalanche (and Spirent Test Center) has been released. I won’t cover STC, but for Avalanche, it’s a pretty big release.

Major features

  •  Action List Generator: You can now use a built-in tool to generate action list. For each action, you pick a protocol. The mandatory parameters are directly shown, and you can add the optional ones by the click of a button. I’ll cover this in more details in a future entry.
  • Easy Test: The old “Quick Test” is gone and replaced by this. You can quickly create a single- or multi-protocol mix from there, mesh the traffic the way you like, define your load (CPS, Throughput, etc…). If you need more options you can simply convert it to an Advanced Test. So this could be seen as a way to do complex operations in a simpler GUI, or just as a nice introduction to Avalanche.
  • Adaptive Streaming (Adaptive Bit Rate): This release moves ABR from Alpha to GA. Microsoft Smooth, Apple HLS and Adobe Zeri are supported, for both Video on Demand (VoD) and Live. You can fine-tune the behaviour of the clients, too. For instance, you can choose if the clients should start from the Maximum, Minimum or Median bitrate. You can also disable the up/downshifting (“Constant”), manually configure it (“Normal”), or have the clients behave exactly like real clients (“Smart”). You can also refer to this blog entry for more details on ABR.
  • Run-time Stats refactor. That’s a big one. The Runtime Stats (the statistics you get while the test is running) have been rebuilt from scratch. You can choose which stats you want to see, zoom in, zoom out, save to PNG or clipboard, and filter by port (or even per core). You can even create your own custom charts to meet your specific needs. Last but not least, you can save “Views” which are templates of graphs. So for example you could have one view for IPSec testing (show active SA, Phase 1 and Phase 2 tunnels, etc…), one for VoIP (with MOS scores and goodput for instance), and so on and so forth. This allows one to load the view for all future tests without needing to build it from scratch every single time.

Some Other features

  • RTSP Bitband client now supports Retransmission
  • Cisco SSL-VPN (AnyConnect) support
  • Fragmentation is now supported for IPv6 traffic
  • It’s now possible to manually specify the OID for SNMP polling – no more MIB required.
  • IPv6 PCAP’s can now be imported in SAPEE (Capture & Replay Engine)
  • It’s now possible to use variables for the file names in FTP
  • Under the hood we moved the RAW attacks from the Vulnerability Assessment module to use the FPGA on the 3100B appliance and STC-based modules. This will drastically improve the DDoS capabilities of this module with no impact on the performances.

This post covers major features and is not an all-inclusive list of features in this release.
