Router OS protocol has been designed from the beginning to give the innovative, flexible, and powerful solutions needed by providers of public access and outdoor point-to-multipoint networks. WI-CORP radios along with RouterOS serve the Metropolitan Area Network and corporate wireless outdoor markets, based on tools like VLAN support, routing, polling, bandwidth management and secure data management.

In mission-critical point-to-multipoint environments, where the wireless network must support numerous interconnected LANs, it is crucial that the wireless bandwidth be used in the most efficient manner. Unfortunately, standard 802.11 protocols are not designed to provide the efficiency and reliability required when used in a building-to-building environment. Problems with hidden node transmitters, scalability, bandwidth allocation, and excessive packet transmission overhead prevent standard 802.11 products from providing the kind of high-performance broadband wireless connectivity that RouterOS- Nstreme delivers.

Utilizing a dynamic base station polling algorithm, RouterOS- Nstreme prevents simultaneous transmission from remote locations, avoids wireless packet collisions, and solves the problem of hidden transmitters. Nstreme polling allows a base station to automatically scale and optimize bandwidth for up to 100 remote buildings. When bandwidth limits are needed, bandwidth allocation can be programmed for the entire network or specific remote locations. Finally, SuperPacket Aggregation combines multiple small packets into more efficient SuperPackets before transmission. This reduces the total overhead associated with packet transmission and dramatically increases performance.

RouterOS operates using IEEE 802.11 set of standards. It uses radio waves as a physical signal carrier and is capable of wireless data transmission with speeds up to 108 Mbps for working as wireless clients (station mode), wireless bridges (bridge mode), wireless access points (ap-bridge mode), and for antenna positioning (alignment-only mode). There are several features implemented for the wireless data communication: WEP (Wired Equivalent Privacy), AES encryption, WDS (Wireless Distribution System), DFS (Dynamic Frequency Selection), Alignment mode (for positioning antennas and monitoring wireless signal), VAP (Virtual Access Point), Fast Frames, disable packet forwarding among clients, and others.

VLAN support and routing are the perfect tools to avoid packet collisions and broadcast storms. RouteOS has, not only routing and VLAN support, but also has Super packet aggregation to overcome distance problems, therefore C-CLASS leads Service providers to build Carrier Class Networks with high return on investment.

Carrier Class Telecom networks now may benefit from the MPLS MultiProtocol Label Switching. IP routing - packet forwarding decision (outgoing interface and next hop router) is no longer based on fields in IP header (usually destination address) and routing table, but on labels that are attached to packet. This approach speeds up forwarding process because next hop lookup becomes very simple compared to routing lookup (finding longest matching prefix).

Efficiency of forwarding process is the main benefit of MPLS, but it must be taken into account that MPLS forwarding disables processing of network layer (e.g. IP) headers, therefore no network layer based actions like NAT and filtering can be applied to MPLS forwarded packets. Any network layer based actions should be taken on ingress or egress of MPLS cloud, with preferred way being ingress - this way, e.g. traffic that is going to be dropped anyway does not travel through MPLS backbone.
