F5 to bring application-layer intelligence to SDN services for software defined data centers

Seattle – F5 Networks, Inc. (NASDAQ: FFIV) today announced that it has agreed to acquire LineRate Systems, a developer of software defined networking (SDN) services. Through this acquisition, F5 gains access to LineRate’s layer 7+ networking services technology, intellectual property, and engineering talent, further building on F5’s commitment to bring superior service agility, application intelligence, and programmability to software defined data centers.

“F5’s vision is to enable application-layer SDN services for software defined data centers, providing our customers with unprecedented automation, orchestration, and control,” said Karl Triebes, EVP of Product Development and CTO at F5. “Extreme scale of applications, infrastructure, and services will be vital to SDN, core to F5, and the key to customers realizing the benefits of software defined data centers. LineRate’s programmable network capabilities and innovations in layer 7 will bolster our efforts to extend F5’s market leadership in these areas, and we are very pleased to welcome the LineRate team to F5.”

Critical to the success of SDN architectures are security, acceleration, optimization, and intelligent traffic management services at the application layer. Application-layer services will be vital to meet customers’ expectations of flexibility, scale, and performance, and to provide significant competitive advantages. The LineRate acquisition aligns with F5’s vision for application control plane architecture and goal of delivering application-layer SDN services to bring superior agility, application intelligence, and programmability to software defined data centers.

LineRate Systems, based near Boulder, Colorado, provides software that offers layer 7+ network services. LineRate’s software defined solution is an early-stage product, which will become an important part of F5’s broad range of development initiatives focused on software defined data centers.

“In order to reap the benefits of software defined data centers, programmable, scalable network services must be present throughout the entire network stack—up to the application layer,” said Manish Vachharajani, Co-Founder and Chief Software Architect at LineRate Systems. “We recognize that the SDN fabric may be good at layer 2-4, but ultimately customers care most about the applications. The LineRate team is excited to join F5 and looks forward to helping F5 accelerate development initiatives in this important market.”

The terms of the acquisition were not disclosed. The acquisition is not expected to have a material impact on the company’s operating results.
