Products : XGLC²⁰ Packet Processing Line Card

XGLC²⁰ Overview

As wirelessly connected mobile devices move more into mainstream life, and the industry quickly moves towards 4th generation cellular technology, the volume of Internet content consumption and the speed of data communications are truly unprecendented. Keeping up with the public's growing apetite for content at ever faster data rates requires a new generation of network elements. Network elements free from yesterday's design limitations and network elements that are power, space, and operationally efficient.

Enter the newest member of the Stoke Session Exchange product family, the XGLC²⁰. XGLC²⁰ is a new packet processing and forwarding line card for the SSX chassis. Built using the same breakthrough One-Hop architecture that eliminates gateway bottlenecks and performance trade-offs, the XGLC²⁰ raises performance and capacity limits to allow operators to build an Evolved Packet Core (EPC) to manage the next phase of the Broadband Mobile Internet.

Feature Highlights

Compatibility
Recognizing that highly economical capacity expansion for gateway applications on today's 3G networks is as important as high capacity for LTE, Stoke ensures feature parity with StokeOS between GLC and XGLC²⁰ configured SSX systems. the XGLC²⁰ is also completely compatible with existing SSX-3000 chassis, IMC management cards, and current SSX power modules and fans. This means that operators with SSX-3000 deployments today using the highly capable GLC line card, can step up throughput capacity by 5 times without changing network element footprint, operating system or other hardware components. This simplifies upgrade procedures and planning, and allows operators to install a lower cost system today knowing they can upgrade "in situ" when capacity demand requires it.

Performance and Scalability
The XGLC²⁰ sets new benchmarks for mobile network session management and packet operations performance and scalability. And Stoke's One-Hop architecture enables the XGLC²⁰ to hit these heights with amazing envionrmental efficiency. As traffic volume and content richness continues to increase both of these factors will become critical.

Here are some of the key performance and scalability factors of the XGLC²⁰.

• 4 x 10 Gigabit Ethernet ports per card (2 x active, 2 x stand-by);
• 20 Gbps (full duplex) full-function, line rate packet processing, consuming < 25 watts per Gigabit
• Session enforcement for up to 240,000 concurrent active sessions
• Identify and enforce QoS policy on greater than 1 million flows per interface
• Line rate encrypted throughput down to 96 byte packets
• Completely redundant configurations using just one chassis;
• Sub-Second failover for 240,000 active, secure sessions without an additional note

The diagram to the right illustrates the scaling of active subscribers and traffic management service classes for the XGLC²⁰ and provides a comparison of the XGLC²⁰capabilities realative to the GLC. The colored boxes labeled "Control" and "Visibility" highlight the granularity of the SSX's traffic management capabilities. .

Applications
Compatibility with StokeOS ensures an SSX configured with XGLC²⁰ can be dployed for currently available SSX applications including::

• Mobile Data Offload enabling the selection and efficient redirection of up to 20 Gbps of Internet bound mobile data
• Packet Data Gateway for 3GPP standard WLAN data services interworking
• Security Gateway for secure aggregation and termination of user-to-network and network-to-network sessions

and EPC applications (currently available and planned) including:

• eNodeB Aggregation for securing control plane, data plane, and management plane traffic in one efficient location
• Network-Based Seamless (Wi-Fi) Access Handover to simplify the multi-access deployment planning and operations
• Hybrid EPC Gateway Applications supporting functions of multiple EPC elements, enabling more efficient or optimized LTE services platform

In addition, the XGLC²⁰ and the SSX system are programmable and highly flexible, and applications to solve specific problems for 3G and LTE deployments can be obtained. Please contact Stoke for more information.
