What’s New in the Latest MEM release?

Midokura is out with a new release of Midokura Enterprise MidoNet (MEM) that supports OpenStack Kilo and Docker.

Embraced by DevOps and NetOps at organizations of all types and by service providers offering public, private and managed clouds, Midokura Enterprise MidoNet is relied upon to provide network virtualization for cloud operators to build isolated networks in software and run at scale.

As organizations continue to launch new application services requiring network changes without service interruptions, new releases of MEM demand a relentless pursuit of quality and performance by Midokura. And with this release, the Midokura development team has really delivered on that promise.

Much of the hard work on this release resulted in major improvements that could be considered “under the hood” and not readily apparent on the surface. Brought to you by the founders who built distributed systems at Amazon and Google, here are some really interesting new innovations in this release.


New Support for OpenStack and Docker

  • Support for OpenStack Kilo
    • MidoNet can be installed in conjunction with OpenStack Kilo or Juno versions.
  • Support for Docker
    • Openstack Kilo version introduces the support of MidoNet for Nova Docker.


Simplify Operations

  • MidoNet Host Agent configuration is now centralized
    Now that the configurations of all the MidoNet host agents are stored centrally in the cluster, agent configurations can be modified using a single command line, further simplifying MidoNet administration for cloud operators.
  • Another time saver are the configuration templates in MidoNet, which can be used for automated setup of compute and gateways. With this release, configurations can be viewed and edited via the MidoNet Manager.
  • Remotely disable/enable debug logs
    The debug logs can be enabled centrally via the CLI or the MidoNet Manager. Changes can be applied immediately without having to restart the MidoNet agent.


Increased Network Visibility

  • Flow tracing
    Building on the previous MEM release, further enhancements have been made to increase network visibility with the addition of flow tracing in MidoNet Manager. Flow traces can be created or listed with condition matching parameters like IP source, IP destination, etc. The details of each flow trace can be viewed with contextual information about the network object. A simple mouse over a bridge shows the name, tenant and the object type.
  • DHCP configuration per network
    DHCP can be configured per network via the MidoNet Manager allowing for operators to set a specific MTU for each network. This function provides cloud operators with added flexbility over what cannot be performed via Horizon.
  • BGP status view
    Details about BGP status are visible in the MidoNet Manager UI:

    • List of routes learned over BGP
    • BGP neighbor status (equivalent to “show ip bgp nei”)


Performance Enhancements for Massive Scalability

Several enhancements have been made to this release to help OpenStack operators run MidoNet at massive scale.

  • Connections to the central cluster (Network State Database) have been made more resilient and robust.
  • Self-monitoring has been added to the Midonet host agent, which will trigger an automatic restart in the event of failure.
  •  Support for Megaflows
    MidoNet Agent now supports megaflows, which has a similar concept in Open vSwitch. Support for megaflows boost performance because it drastically reduces the number of packets traversing the slow path into user space. Previously requiring exact-match cache, the kernel cache now supports bitwise wildcarding which means the flows no longer have to be individually processed by the MidoNet agent.
