PROGRAMMABLE FORWARDING PLANES
FOR THE INTELLIGENT TOP-OF-RACK
NoviFlow switches implement the next generation networking technology – a programmable forwarding plane with match+action rules in a fully programmable pipeline, ideal for implementing network intelligence at the Top-of-Rack. NoviSwitch ToR switches enable in-rack network policy enforcement, keep east-west traffic off of leaf-spine switches, accelerate the deployment of virtualization, NFV and vEPC, reduce the need for proprietary appliances for cyber security and load balancing, and decrease operating costs by reducing operator errors.
IN A CLOUD COMPUTING WORLD,
THE ToR IS THE NETWORK'S EDGE
With the arrival of virtualization and cloud computing, applications and services migrate back and forth across the network in response to the availability of and to ensure optimal use of compute, storage and bandwidth. In this world, the concept of the network edge has shifted, as east-west traffic becomes ever-more dominant, multiple tenants compete for resources, and cloud providers may not even know what software is being run on their servers. In this world, the servers within a datacenter cannot be considered truly secure, and the Top-of-Rack becomes the point from which policy, security, automation, and service access is controlled.
To complicate matters, the vast multiplication of connected devices and BYOD are placing extreme requirements for flexibility in access to network based services. Consequently, service providers want to build infrastructures that would as much as possible allow enterprise customers as well as end users to provision themselves in an easy to use yet centrally controlled fashion. SDN provides the tools to implement this infrastructure as an overlay on existing systems, but unfortunately most ToR switches lack either the table capacity, programmability or throughput needed to implement such solutions.
THE NOVISWITCH DIFFERENCE
Unlike legacy network equipment, NoviFlow’s NoviSwitches have designed from the ground-up to deliver a networking fabric optimized for implementing programmable forwarding planes: very large table sizes, multiple tables, packet payload matching and traffic handling at line rate for even hyper-scale networks.
NoviSwitches uses Network Processors (NPUs), which provide both high throughput and full programmability. When combined with NoviFlow’s NoviWare NOS, NoviSwitch provides a silicon based forwarding plane that is 2 to 3 orders of magnitude faster than x86 processors, yet can deliver the fully programmable packet pipeline needed to provide both the agility and scalability required by today’s networks.
NoviFlow’s NoviSwitches offer a fully programmable high-performance forwarding place in a 1U format, ideal for use at the ToR. NoviSwitch SDN switches have many advanced features that significantly reduce expenses by implementing remotely managed customer capabilities, and that enable transparent access to network services across domains using advanced tunneling, and flow management capabilities. They also offer huge access control lists, advanced metering capabilities, load balancing, security mitigation, service chaining, filtering and flow handling and that allow users to provision themselves via a central site. Used with the NoviFlow vSwitch Offload solution they can even liberate significant in-rack compute resources by eliminating the need to reserve server CPU cores for running local v-switches.
Also, each NoviSwitch runs the NoviWare Network Operating Software (NOS) which is field upgradable, so that new features and capabilities can be added via software upgrades, protecting the value and prolonging the useful lifetime of installed switches.
