StokeOS Overview

As mobile operators move toward providing high speed, media rich services to mass markets, new platforms and new operating systems are needed with the right underlying architecture and feature set to ensure ongoing service differentiation, rapid time to revenue, operational efficiency, and high availability. StokeOS is a powerful operating system and a rich set of tools for IP service enablement. Optimized for 3G and LTE gateway functions, Stoke OS supports the latest features to enable advanced multimedia services, improve operator visibility and control with application awareness, ensure secure subscriber communications, and deliver intelligent mobility for across a range of network wide. In addition, StokeOS is optimized for availability, with individual, dynamically restartable, processes running in protected memory on top of a hardened microkernel. Stoke developed middleware features advanced self-monitoring and self correcting capabilities as well as state checkpointing and replication to ensure session persistence even through failures of essential system components. StokeOS also features self protecting capabilities to mitigate the impact of DoS attacks on the SSX. To view StokeOS specifications click here.

StokeOS includes a broad range of functions and supports a variety of access gateway roles (note color coding of the "Deployment Mode" level; orange indicates roles available today, yellow indicates planned).

StokeOS Feature Highlights

Session Management
The mobile broadband opportunity is forcing new requirements on carrier edge networks. In addition to managing much higher data rates and volumes, along with longer active session durations, Stoke delivers a wide range of IP session management capabilities including:

• Multiple access technology support
• Scalable session security
• Optimal multimedia session delivery
• Application awareness and control
• QOS and policy enforcement
• Flexible service definition and charging
• Mobility: Session continuity over multiple networks

Each function above is required to deliver an exceptional mobile broadband Internet experience. These functions ensure secure multimedia sessions over multiple access networks including support, control, and properly monetized in-house and over-the-top applications while providing seamless mobility for subscribers moving between access points and access networks.

Policy Enforcement
With key session management features in place, the StokeOS, together with the SSX-3000 enables operators to enforce subscriber and network wide policies to keep control of network use, ensure proper billing for services, and meet service level agreements. StokeOS supports DIAMETER and RADIUS, common protocols for retrieving policy information from PCRF functions and/or AAA servers. StokeOS applies access, charging, QoS, and use policies to individual sessions.

Policy enforcement functions are tightly coupled with Stoke application awareness capabilities to enable fine grained policy definition and application. For example, combining these capabilities combined enables operators to implement creative application accounting and charging solutions for home grown or partner content services.

Virtualization
StokeOS provides the foundation for provisioning, delivery, and charging for the next generation of multimedia services. Virtualization of the chassis provides a simple and efficient means of aligning the network with a broad range of market-driven retail and wholesale service models.

A context is a virtual router configured within the SSX, and the SSX can support up to 250 virtual routers or contexts – a single SSX chassis can be configured to appear as many separate logical routers. Every context runs routing protocols and has its own addressing domain, routing table, interface table, ARP table, and host table so address spaces can overlap. Because contexts behave as autonomous routers they can also be privately addressed, supporting multiple MVNOs and/or Enterprise customers.
