Various systems and methods for fault-tolerant and otherwise optimized communication, in which a system includes communication nodes connected by wireless data links together forming a ring structure, as well as additional wireless data links operative to partition the ring structure into multiple sub-ring structures. The system is operative to select, per each of the sub-ring structures, one of the wireless data links to remain dormant, thereby effectively creating a certain communication tree structure. The system is further operative, upon detecting a communication problem or inefficiency in any or all of the sub-ring structures, to shut-down, per sub-ring structure detected, the problematic or otherwise inefficient wireless data link, and to reactivate instead the dormant wireless data link, thereby effectively switching to a new communication tree structure, and thus resolving the problem or otherwise improving efficiency.

Extended ring-like communication architecture

A system for protection switching in radio networks includes a plurality of nodes, a plurality of links of Ethernet interconnecting the nodes and forming a network, at least one wireless link interconnecting two of the nodes, and two Virtual Local Area Networks (VLAN) within the network, only the first VLAN comprising the wireless link. The network transports packets of Ethernet associated with a first Classes of Service (CoS) and a second CoS via the first VLAN. Upon detection of a reduction in performance of the wireless link, the network maps the second CoS to the second VLAN, and by that offloading traffic associated with the second CoS from the wireless link.

Protection switching in radio networks

A system includes a networking enabled system and a packet radio system. The packet radio system includes a wireless interface and a packet interface. The packet interface includes at least two queues, each queue configured to store a certain class of packets of Ethernet. A cable is operative to transport the packets from the networking enabled system to the packet interface using Ethernet signaling. The packet interface is configured to ascertain from time to time the rate at which the packets are sent from the queues over the wireless interface, and according to the rate, indicate dynamically to the network enabled system the classes of packets for which packets are to be sent over the cable for storage in the appropriate queues. The network enabled system is configured to send, over the cable, packets of classes indicated by the packet interface, while holding back other packets.

Integrated quality of service interface for ethernet radio

A system for fault-tolerant communication includes N nodes, out of which one is a gateway node, and N data links, each data link connecting two of the nodes, forming a ring structure. At least two of the data links are wireless data links. The system substantially do not use one of the wireless data links to send data, effectively partitioning the ring structure into a first chain and a second chain. The system sends data downstream direction and upstream direction, through the first and second chains. The system detaches at least one node from the first chain, by substantially stop using a wireless data link having a reduction in performance and belonging to the first chain, and connects the at least one node to the second chain by starting to use the wireless data link that was substantially not in use.

Ring-like communication architecture

A system for communicating between Radio Access nodes includes a Radio Access Network (RAN) comprising a plurality of Radio Access nodes and a backhaul system interconnecting the Radio Access nodes. The backhaul system identifies at least some paths belonging to the backhaul system, each path interconnecting a pair of Radio Access nodes belonging to the RAN. The backhaul system ascertains, per path, at least one type of Traffic Engineering (TE) metric associated with transporting data between a pair of Radio Access nodes, and convey, per path, the TE metric, to the pair of Radio Access nodes. Optionally, the pair of Radio Access nodes perform a real-time data exchange, provided that the TE metric, conveyed to one of the Radio Access node of the pair, indicates that such an exchange is viable using the path. Optionally, at least some of the paths comprise wireless data links.
