C-CORE OEM MESH driver

One of the few in the World to offer Multi-radio and Multicast OEM Mesh software

CRL with its unique C-CORE 2.0 is possibly one of the few on the global market to provide mesh drivers which supports both fully autonomous Multi-Radio technology and Multicast support as OEM software for product manufacturers. CRL Sweden even offers Mesh drivers and integration services of IP communication software for Non-IP packet radios.

With C-CORE 2.0 you are one step ahead of any competitor in multi radio support

Most of those few product vendors offering third generation Mesh technology today actually needs three radios to support dual Mesh backhaul. Two radios makes the Mesh backhaul, and athird radio one is used for automatic channel allocation. The C-CORE 2.0 mesh driver does the same by using only two mesh bakhaul radios, with no impact on the network bandwidth. If adding a third radio for Mesh backhaul, well then you will just get another almost 50% bandwidth increase!

CRL provides high performance next generation OEM Mesh Software Technology for Product Vendors and System Integrators. Our customized products can be distributed as OEM Software component in networking equipments as well as integrated in customer’s proprietary system solutions enclosed with Firmware, Configuration and Management Software.

With the novel Multi Radio (MCMR ) technology of C-CORE 2.0 all radio nodes are communicating on separate channels. Channel and radio assignment for each node is full autonomous and instant adaptable and needs Zero configuration. With CRL MCMR technology the bandwidth does Not decrease over many hops.

Multi-Channel Multi-Radio (MCMR)

Equipping nodes with multiple wireless interfaces is a cost-effective way to significantly increase the overall throughput in a wireless network. This advanced and powerful feature is easy to configure with few parameters. Once deployed, the nodes dynamically and autonomously choose frequencies aiming to diversify frequency usage, consequently maximizing the networks performance. The feature is suitable for both static networks and mobile ad-hoc networks where nodes can leave and enter arbitrarily.

• Support for multiple wireless network cards per node
• No modifications required to existing protocols and
   applications
• Increased throughput in single-hop and multi-hop
   networks
• Negligible overhead for channel management
• Channel switching does not introduce high latency
   due to optimized channel switching time (1 ms)
• Full support for Multicast
• Automatic channel selection algorithm
• Support for Roaming Nodes using a Single Network
   Card
• Optimized Support for omni-directional and directional
   antennas
• Suitable for both static and dynamic ad-hoc networks

 

 

True Mulicast

C-CORE 2.0 supports Single-Source Multicast within the Mesh Network as specified by RFC 1112, using the designated multicast address space specified by RFC3171. By its modular design, the Multicast Support is also available with Multi-Channel Multi-Radio Operation with channel switching and the use of multiple frequencies where adjacent multicast subscribers may be using different frequencies.

• Efficiently deliver data from one source to multiple
   destinations with a fraction of network bandwidth impact compared to unicast
• Suitable for real time applications with minimal
   latency and highest QoS
• Fully compatible with Multi-Channel Multi-Radio
   (MCMR)
• Provides higher quality video and audio streaming
   due to single stream from source
• Good scalability - Each receiver does not require a separate data stream from the
   source

Mesh networking over Non-IP radios

For non-IP compliant radios such as various UHF modems, CRL has developed a Virtual Ethernet Adapter which provides virtual IP over an arbitrary radio.

Currently, the Virtual Adapter is available for both Linux and Windows and is configurable and/or extendable to support different types of radios with or without proprietary link layer protocols.

Product ready implementations

Along with Mesh Products and Software, CRL has solid expertise in product ready Mesh driver software and implementations. These protocols are either delivered as Mesh driver software for customer integration, or combined with complete firware as Linux-based OS, configuration tools, security tunneling, encryption and Network management application.

The Technology foundation behind the CRL Mesh drivers
The Generic Software Framework C-CORE: CRL-Custom Optimized Routing Engine)

CRL has profound experience of 7 years in Mesh Technology Research behind its Mesh Drivers based on a Software Framework. The Mesh Framework has a unique modular design which makes it very convenient to adjust the Mesh implementation to multiple Platforms, Operating Systems, Ad Hoc Routing Algorithms and Services. We at CRL are the trend setters; as our CRL’s Mesh Driver Technology has brought about a new revolution in this division and opened new horizons. The algorithms that handle the Ad Hoc Routing Communication in the Mesh are all capsulated in modules with sophisticated and dynamic interfaces which can be exchanged as plug-ins to the framework. All other functionalities such as Memory Allocations, Routing Tables, QoS, Security, Encryption, Operating System and Hardware dependent parts are all encapsulated in separate modules. For instance, all operating system reliant units are completely separated from the Networking Logic and Ad Hoc Algorithms. This ensures both faster development and more robust system where each module in the framework is thoroughly stress tested and validated thoroughly over a considerable time frame. Within a short development time it can be customized to conform to another optional standard protocol or proprietary algorithm.

The generic framework made up of highly optimized and stress tested c-code partitioned into a large number of framework modules and plug-ins. After compilation the result is a much optimized binary with small memory footprint for the customers’ specific application usage characteristics adjusted for customer chosen hardware and OS platform.

Mesh enabled Access Points for urban broadband networks

Broadband networks with mesh enabled access points forming backhaul network for wired, as well as wireless client nodes.

Mesh for long range and tactical SDR or legacy radio systems

Packet radio communication with dynamic, scalable and redundant topology via multi-hop enabled mesh data forwarding.

Mobile Mesh for tactical response networks and telemetry

Mobile Mesh networks between cars, buses or trucks for telemetry applications, tactical response networks or mobile hotspots. The mesh software can be specifically designed for mobile network scenarios and applications, or mobile nodes to seamlessly mesh with a fixed back-haul mesh network.

C-CORE Optimizations

Purpose built implementations and optimizations are possible in the mesh framework within a short period of time with very competitive prizing.

Examples of potential Custom-made features

• Customer specific requirements for QoS in the Mesh Routing
• IPv6 Support
• Integration interfaces for Customer Proprietary Algorithms: for e.g. QoS,
   Radio Interfaces, Link Quality Calculations
• Reactive routing adjustments for Silent Networks, with most possibly minimal network
   traffic necessary, for example, required mobility, latency or network status control
• Energy Efficient Routing or other special rule based metrics for choice of routing
• Client rule based gateway selection for Multiple Gateways
• Multiple QoS user profiles: differentiated Network user profiles based on bandwidth,
   latency etc.
• No Virtual Network partitions
• Possible to exclude unwanted channels/frequencies
• Support for Roaming Nodes using a Single Network Card (mode dependent)
• OS platform porting: Linux, QNX
