October 15, 2012, 11:10 AM — Midokura, a Japanese startup focused on network virtualization, this week said it is entering the U.S. market with a distributed software defined network product designed for Infrastructure as a Service (IaaS).
The companys MidoNet software virtualizes the network for multi-tenant public and private cloud computing, and supports the industry-defined OpenStack platform for cloud computing virtualization, automation and orchestration. MidoNet is a de-centralized software overlay where network intelligence resides in the edge rather than in a centralized controller, which is the common architecture for SDNs.
WHAT'S THE USE? What are the killer apps for SDNs?
Management and configuration of the MidoNet SDN occurs centrally, however. The software does not support the OpenFlow protocol or API, company officials said, citing its immaturity for cloud IaaS applications.
The features of MidoNet include:
* Virtual Layer 2 distributed switching and isolation
* Virtual Layer 3 distributed routing and isolation
* Layer 4 load balancing and firewall services
* Access Control Lists
* Virtual port and device monitoring
* Restful API
* Web-based management control panel
The MidoNet software resides on x86 machines configured as edge gateway nodes, compute hosts and network state database hosts. It allows cloud providers to create virtual provider and tenant routers that provide BGP multi-homing, maintain global NAT and route settings, and deliver firewalling, load balancing, DHCP and NAT services to individual tenant networks.
These x86 MidoNet hosts effectively serve as line cards in a grid router, Midokura says.
