New Version of the Stratosphere SDN Platform Provides Extended Functionality for Network Virtualization

TOKYO, — February 7, 2013 — Stratosphere Inc. (“Stratosphere”), a joint venture established by ACCESS CO., LTD. (“ACCESS”) and Internet Initiative Japan Inc. (“IIJ”), to conduct R&D on infrastructure software based on software defined network (SDN), today announced the latest version of the network virtualization platform Stratosphere SDN Platform 1.1 (SSP 1.1) will be released on February 28. SSP 1.1 will be sold to data center operators, cloud service operators, telecom operators, service providers, and others through ACCESS and IIJ sales channels. 

Stratosphere SDN Platform (SSP), which was initially released on October 31, 2012, is a software stack that virtually builds and controls a network that connects virtual machines distributed over a wide area. SSP is unique in that it integrates a variety of conventional network technology with new technology to create an SDN environment. The function modules allow flexible network configuration to meet the individual needs of the client company, and support is provided to achieve seamless migration from the existing network environment. The latest version, SSP 1.1, expands the scope of application for SDN through Multi-Protocol Label Switching (MPLS), allowing connectivity with WANs, corporate LANs, API extension, and other features. 

    The new features include the following: 
  1. MPLS compatibility (extension to WAN)
    An MPLS network can be used to connect virtual networks between data centers. High-performance networks functions that MPLS provides can also be used on an SDN, which enables the virtualization of an entire wide-area network. 
  2. SDN Gateway (extension to LAN)
    An existing corporate LAN environment can be securely connected to a virtual network in the cloud that is managed by SSP via SDN Gateway by using IPSec VPN tunnel. 
  3. Two-tiered API
    The API is designed to meet the needs of both the end user and the service providers. Service providers can use the API to build customized services. The next version is scheduled to include a three-tiered API with additional functionality for infrastructure providers. 
  4. Original plugin for CloudStack
    CloudStack is a cloud infrastructure open-source application that manages virtualized machines and networks, and in the past a plugin designed by Nicira, Inc., was used to connect with CloudStack. SSP1.1 provides a proprietary plugin that will be used to provide a Stratosphere proprietary function. 
  5. Optimized broadcasting feature (extension to VXLAN) 
    To reduce the communications overhead of broadcast traffic by routing it over VXLAN, the IP multicast method or broadcast engine is used to optimize the traffic load. This avoids the performance degradation associated with edge overlay SDN. 
  6. Support for both packet conversion configurations (separate and built-in)
    SSP can be used for a built-in configuration, in which the packet conversion virtual switch processes are performed on a physical server, or in a separate configuration, in which a dedicated device performs this function. Until now, the user had to select one configuration or the other, but with their coexistence on SSP1.1, either type of system can be constructed.

We will continue to add compatibility with different platforms and protocols to bring both service operators and end users a user-friendly SDN environment.

About Stratosphere
Stratosphere Inc. was established in April 2012 with the goal of researching and developing software stacks that could build a platform to create the next-generation cloud environment using software defined network (SDN) technology. The company was named after the stratosphere, a part of the Earth’s atmosphere that is above the clouds, representing our goal of going beyond the cloud. The stratosphere is also very stable and covers the more turbulent troposphere, which reflects our mission to provide technology to engulf the entire cloud computing environment and stabilize and develop it.
