Stoke announces XGLC20 for LTE gateway apps

4G WORLD, CHICAGO, USA: Mobile broadband gateway developer Stoke Inc. announced the XGLC20, extending the range of its Stoke Session Exchange (SSX) platform with a new packet processing card targeting LTE deployments.

The increased capacity enables mobile operators to reduce the cost per bit for 4G data service delivery while in-depth, line rate packet operations raises the network’s “content IQ” to enable service differentiation and promote network preference among the Internet’s content suppliers.

The SSX family of session management platforms was designed and developed to deliver a wide range of mobile broadband gateway functions to meet the challenges of data services for 3G and 4G network deployments. The XGLC20 extends Stoke’s signature line rate session management, encryption/decryption, and visibility and control, with enhanced capabilities, including five times the throughput and up to four times the session management capacity.

Expanding capacity is critical to managing LTE traffic rates and expected data volumes. For LTE service business models to succeed, operators must also drive service delivery costs down substantially. Power consumption, rack space, and cooling requirements, as well as capital expenses, all factor into the cost of service delivery.

The XGLC20 operates at greater than 10 Gbps per rack unit while consuming less than 25 watts per Gbps. It also delivers the highest managed session throughput per CAPEX dollar today, and manages to set new performance and capacity benchmarks.

Mike Homeier, vice president product management at Stoke, said: “To take on the next phase of mobile bandwidth and data volume growth, operators must consider the deployment of LTE a clean slate. Simply taking on significant expenses by upgrading yesterday’s network elements will not deliver the expected results in the long run. The XGLC20 helps mobile operators realize the promise of LTE—high-speed mobile data services at a fraction of the cost of 3G.”

“Packet core network elements must evolve to keep ahead of the connectivity demand, data rates and traffic volume associated with 4G,” said Jennifer Pigg, vice president, Yankee Group. “Network operators are investing in flexible solutions that can meet these expanding network needs while lowering costs, both CAPEX and OPEX, and enabling operators to monetize the network.”

Enhanced capacity and capabilities for evolved packet core gateway applications including:

* All packet operations function at line rate inclusively (i.e. L4-L7 traffic classification; encryption and decryption; policy enforcement, QoS, and accounting).
* 20Gbps (full duplex) line rate processing per line card.
* Up to 240k active concurrent sessions and 3.8M active service classes per card.
* 4 x 10 Gigabit Ethernet ports (active and standby) per line card.
