High-Performance Architecture for Sophisticated Services

This state-of-the-art software architecture enables a linear performance increase with the addition of CPU cores, delivering ASIC-like performance and processing latencies.

A hardware accelerator identifies traffic flows and distributes associated packets to multiple CPU cores. Packets are processed in parallel in the new OneOS V6.0 distributed packet engine. Because packet processing is fully managed as software, the ONE2540 brings the inherent advantages of software (versus hardware) solutions, namely: rich, extensible services. Compute-intensive services such as application visibility and control can be run concurrently at Gbps speed thus greatly improving user experience.

Scalability in Number of Users and Services

The ONE2540 is intended for use in headquarters and data centres. As a result, it needs to support a large number of users and the termination of flows from many branches. For this reason, the ONE2540 is equipped with a large memory (8 GB of RAM). Many users imply many user flows and associated firewall / NAT / … sessions. Up to 500k sessions are supported to serve potentially tens of thousands of users. This large RAM enables to accommodate a large number of remote branches where many VPN, logical links or BGP prefixes must be handled.

Reliable Services

The ONE2540 hardware architecture and software eliminates points of failures and thus increases service availability to the standards expected in critical locations such as data centres. Redundant power supplies warranty continuous operations during outage of a power supply. Fans and power supplies are hot-swappable for service continuity during hardware maintenance. The Error Code Correction (ECC) RAM verifies and corrects data integrity. Such RAM is typically found in carrier-grade servers and now available in the ONE2540 platform. Service availability is enhanced because software is protected against data corruption.

The ONE2540 integrates in various network topologies to provide redundant network access. While multiple paths are available, the ONE2540 can share the load between WAN links so as to maximise the available network capacity. A combination of layer-2 and layer-3 Operation, Administration and Maintenance (OAM) protocols enables the ONE2540 to quickly detect network failures and trigger fail-over to available links.

Unified Management from Branch to Headquarters

The ONE2540 is an instrumental piece to build a complete corporate network with the OneAccess portfolio. The range of OneAccess Multi-Services Access Routers (MSAR) provides smart enterprise solutions from small branch offices to headquarters. All MSARs are managed through common, standardised protocols for a unified, one-stop-shop management solution.
