Continuous Computing has developed an Internet Offload reference platform that leverages its recently upgraded FlexTCA 40G platforms. The Continuous Computing AdvancedTCA platform includes a new high-performance Intel Xeon processor 5600 series-based single board computer (SBC), Trillium protocol software and core reference application functions to create radio access network (RAN) and core-based Internet Offload equipment.
The target application is mobile data traffic offload. This can be accomplished by offloading high-bandwidth, non-revenue-generating traffic at the edge of the 3G or Evolved High Speed Packet Access (HSPA+) mobile core prior to reaching the Serving GPRS Support Node (SGSN) network element. Continuous Computing said its solution is especially effective when used in combination with Deep Packet Inspection (DPI) on the Iu interface to help identify traffic for offload and prioritization — and Continuous Computing also provides FlexTCA platform solutions for that function as well.
Key features include:
- Carrier-class FlexTCA 40G and FlexTCA 10G integrated platforms, including chassis, switch, forwarding and CPU blades; scalable from 10G to 100G capacity; a new Intel Xeon processor E5645-based SBC boasting two higher-performing 6-core 2.4GHz processors, 64GB memory and over 1TB of storage
- Robust classification and traffic identification reference application software
- Passive IuPS and related control plane / forwarding software that “sniffs” signaling messages prior to making hand-off decisions; ensures that network operation is not adversely affected
- Field-proven Trillium Diameter software interfaces to policy servers
- New switching configurations and capabilities that allow sessions to be re-established rapidly toward the Internet or SGSN as required
- Optimized Trillium Stream Control Transmission Protocol (SCTP) and Trillium Generic Tunneling Protocol (GTP) that enable the system to deliver maximum performance.
