Atoll Router is intended for organization of interaction between geographically distributed networks over non-secure and secure communication channels. Router operation mechanisms are optimized for packets transmission over lower-bit-rate channels with high error rates.

Atoll Router is a legacy device which is out of production. Due to large amount of installed units we are still supporting this device. For customers interested in Atoll Router purchasing we recommend considering Atoll-M Router as a replacement.

PRODUCT HIGHLIGHTS:

• Capable of working over low quality links with error rate up to 10^-2 per bit. Atoll Router is optimised for use with radio links, including high (HF) and very high frequency (VHF) band ones. Performance characteristics of such links change from one minute to another due to atmosphere conditions, changes in the object locations, etc. The router constantly monitors links' performance and chooses the most approriate data transmission options and routing rules. This often increases the transfer rates several times compared to "dumb" routing and can make the difference of having a working connection.
• Dynamical routing information distribution allows for automatic discovery of new subnetworks and links. Information about these nets, links and their characterisics is supplied by other routers via some version of the routing information protocol. This is especially important for mobile settings when the network configuration changes often (e.g., a new ship comes within the UHF communication range).
• Mandatory access control provides routing and filtering based on packet security labels conformant to IPSO (RFC 1108) specification. Used in combination with OS and application software that also support mandatory access control, it ensures that no confidential data will be sent to an untrusted destination or over a non-encrypted link.
• Multimedia awareness means improved support for real-time traffic, e.g., VoIP. To the end user it means less distortion and lower latency making possible two-way communication with telephone quality. Technically, packets coming from/to certain ports or addresses, or having a certain combination of ToS bits set, can be routed differently than "normal" packets with the same destination (e.g., over a low-latency link). Real-time traffic has higher priority and gets transfered first. Several packets with different destinations are sent over the same link simutaneousely in the interleaved fasion to minimze jitter.
• Suitable for shipboard and mobile usage due to robust rack-mounted design, high resistance to acceleration, vibration, changes of temperature and humidity.
