Trillium Data Plane Protocols

The new FlexTCA platform from Continuous Computing provides an integrated solution to meet new service and capacity requirements for applications such as IPTV, 4G Wireless, FMC (fixed mobile convergence), IP Multimedia Subsystem (IMS) border gateways, and more. It is unique in providing full integration between protocol stacks, Service Availability Forum (SAF) high availability middleware, platform management, and a range of AdvancedTCA blades and chassis options. Specifically the FlexTCA system and associated FlexPacket ATCA-PP50 blade is supported by a comprehensive range of networking and routing protocols to meet the needs of these next generation network elements.

The Trillium Data Plane protocol suite provides a range of networking control protocols for routing, connectivity, security, and mobility, with optimized fast path functions to maximize system performance and efficiency. The solution is modular, enabling developers to separate the Linux-based control protocols from the fast path functions which are created using a lightweight C-based executive called RMI OS. This approach delivers maximum flexibility for operating with pre-existing control plane software.

Fast path functions are ported to the PP50's XLR packet processors and use RMI OS- and hardware-specific accelerators to deliver maximum performance for functions such IP forwarding, IP in IP, IPSEC, VR (Virtual Router), etc. The software is optimized to deliver maximum performance for all packets sizes, with specific optimization for small packet sizes. Specifically, the IPSEC fast path is optimized to make use of the XLRs' autonomous security engines and the packet distribution unit. Unlike with alternative packet processors, this approach enables >10Gbps of IPSEC to be supported using only a small number of the MIPS cores, thereby leaving the other MIPS cores to perform other useful tasks.
