Fujitsu Laboratories Limited announced that it has developed technology for accelerating wide-area network (WAN) speeds, adapting to different characteristics such as packet loss and delay prevailing on communications networks, including mobile and international networks. The new technology was able to double previous transmission speeds on such WANs.

Existing technologies for accelerating WANs typically require identical accelerator hardware at both endpoints of the WAN, and make no accommodation for the differing characteristics that may prevail throughout a WAN. As a result, depending on the WAN, they were not always able to draw out maximum performance levels.

With this new technology, accelerators are distributed throughout the WAN to automatically select the communications protocols best suited to the network characteristics between accelerators, as well the corresponding sections of the network to which they apply. This has the effect of maximizing speeds between the client and the application server. We developed the technology on software, and testing conducted with the National Institute of Informatics confirmed that the new technology could achieve roughly double the transmission speeds of previous WAN acceleration technology when using mobile devices in Japan to access cloud services abroad.

In light of the ever-increasing volumes of communications traffic expected with the trend toward higher-resolution images and support for real-time communications, this technology enables the creation of communications infrastructure that allows the efficient use of available network bandwidth. When applied to network functions virtualization (NFV)(1), this technology enables the provision of fine-grained network services that are coordinated with a variety of network functions, such as firewalls and load balancers.

Details of this technology are being presented at SoftCOM2014, the 22nd International Conference on Software, Telecommunications and Computer Networks, opening September 17 in Croatia.
