Evolutionary DPI platform, integrating network intelligence, policy control and revenue-generating services in a carrier-class solution

• Control costs through efficient management of 10GE and 1GE links
• Increase profitability by deploying services in the platform
• Obtain actionable network intelligence per application, subscriber, content
• Reduce service deployment complexity and time-to-market
• Ensure QoE for all services, including over-the-top
• Protect investment in infrastructure and pay as you grow
  

Allot Service Gateway Sigma (SG-Sigma) is a carrier-grade, highly scalable DPI-based platform for broadband optimization and service deployment in fixed and mobile networks. As the next step in the evolution of the Allot Service Gateway approach, SG-Sigma is designed especially for mobile and next-generation networks, providing built in readiness for 3G, 4G/LTE and converged environments.

With 40 Gbps of throughput, SG-Sigma enables operators to manage high-speed broadband performance; to control infrastructure and operating costs; and to generate new revenue streams through the deployment of network and subscriber services.

SG-Sigma Feature Highlights

Core DPI services: Real-time and long-term monitoring and reporting, usage profiling and demographics, fair use management, policy enforcement, traffic prioritization and shaping, and QoS control.

Network and Subscriber Services: The network intelligence provided by SG-Sigma facilitates fast and cost-effective deployment of value-added network and subscriber services such as URL filtering (parental control), media caching and acceleration, DoS/DDoS protection, outgoing spam protection, as well as tiered and quota-based services.

Extreme performance: Supports throughput of up to 40 Gbps and up to 40 million concurrent flows in a single platform.

Topology awareness: Infrastructure and cell-aware monitoring and enforcement capabilities designed to help operators manage broadband traffic and reduce backhaul congestion.

Subscriber awareness: Per subscriber monitoring, service provisioning and policy enforcement provided by full integration with Allot Subscriber Management Platform.

Online policy and charging enforcement: Designed for smooth integration and interoperability with GGSN and policy decision points (PDP) in existing 3G and evolving 4G mobile broadband networks. Provides online service metering and policy enforcement using DIAMETER Gx, and online charging using DIAMETER Gy and offline charging using DIAMETERGz.

Actionable Network Intelligence: Equipped with Allot’s most advanced DPI engine, providing Layer-7 application awareness with extreme accuracy at very high speeds and peak loads.

Flexible scalability: Pay-as-you-grow deployment reduces initial capital outlay and allows operators to add services or upgrade capacity at any time.

• Performance: Modular blades deliver incremental throughput from 10 to 40 Gbps
• Port Density: Up to 8 x 10GE or 16 x 1GE interfaces for network and service connectivity
• Subscribers: Supports up to 1.6 million subscribers per platform
• Services: Supports multiple network and subscriber services deployed on hot-swappable blades hosted in the platform or deployed externally

Open architecture: Standard interfaces, protocols and APIs facilitate rapid and trouble-free integration of third-party network and subscriber services.

High availability: Active redundancy at the system level and resiliency mechanisms such as blade level redundancy enabe service continuity with no downtime due to component failure..

Carrier-grade design: Engineered to AdvancedTCA^® standards for deployment in service provider networks
