    摘要： A method for enabling provision of service-levels in an Ethernet-over-synchronous communication network, by: receiving Ethernet frames at an input rate; mapping the Ethernet frames into a synchronous protocol; generating a pause signal after a received amount of Ethernet frames reaches or exceeds a threshold capacity level, the pause signal being generated in accordance with a service-level agreement (SLA) determining an output rate based upon an aggregate rate enabled by K memory containers out of N available memory containers, where K and N are integers; and outputting the mapped data frames from the K memory containers thereby providing synchronous transmissions at the output rate.

    摘要： A method for high speed dissemination of information about faults in spans that interconnect nodes in a telecommunication mesh-type network, the method comprises creating a Failure Updating channel (FU channel) in the network and circulating Failure updating messages (FU messages) via the FU channel between the network nodes, wherein each of the FU messages issued by a particular node is disseminated to its adjacent node(s) and carries information about all spans in the network currently available to the particular node, by presenting status indications of the spans in respective information slots of the FU message.

    摘要： A method for utilizing a Spanning Tree Protocol (STP) in an Ethernet network wherein a number of VLANs are defined and a plurality of Ethernet switching nodes (A, B, C D E, F,G H) are interconnected via their ports (A1, . . . ,H4) so that each of the ports is initially assigned to one or more VLANs, and each of the VLANs is intended to enable traffic between two or more edge ports (D3, B3). The method comprises a so-called pruning procedure initiated upon establishing a new STP topology (30) related to one or more VLANs. This procedure concerns a broadcast domain of at least one of the VLANs and is aimed at obtaining a sub-tree for each pruned VLAN in the new STP topology. The sub-tree is usually shrunk, bound by the edge ports assigned to the corresponding pruned VLAN, and thus eliminates broadcast traffic of the pruned VLAN to any Ethernet switch extending beyond the obtained sub-tree.
