Continuous Computing Optimizes for LTE EPC and Femtocell Gateway Efficiency

Continuous Computing announced that its Trillium Stream Control Transmission Protocol (SCTP) FastPath software has achieved a 10X performance improvement over generic user-space SCTP implementations. Trillium SCTP FastPath leverages the 6WINDGate packet processing software suite from 6WIND and its optimized performance is delivered via the FlexPacket ATCA-PP50 Deep Packet Inspection (DPI) blade from Continuous Computing featuring dual NetLogic Microsystems XLR732 multi-core processors.

Trillium said the choice of SCTP as the IP transport layer for mobile data networks has placed a huge strain on SCTP processing that was not envisioned when the SCTP protocol was defined. Massive growth in smart phone usage is consuming signaling resources and impacting throughput in the signaling plane, while rapid gains in the number of connected devices and base stations limits scalability because each reliable connection requires significant signaling capacity. This strain will be felt in the femtocell market where hundreds of thousands of connected femtocells will be managed by a single Femtocell Gateway (FGW), as well as in the LTE market where the Mobility Management Entity (MME) in the Evolved Packet Core (EPC) will face similar challenges from the multitude of small cell deployments.

Trillium SCTP FastPath software moves SCTP into the native execution environment on the PP50 to yield unprecedented scalability; achieves a 10X improvement over generic user-space implementations of SCTP. This supports over 1 million packets per second and over 60,000 associations of SCTP traffic on just three of the 16 available processing cores of the PP50 blade.
