摘要： A dual homing technique for ensuring loop free transmission of traffic between telecommunication networks such as VPLS by utilizing a loop protocol in the dual homed connection. The technique also provides selective handling of VPLS data streams protected and non-protected by the dual homing loop protocol.
摘要翻译： 一种双重归属技术，用于通过在双归属连接中使用循环协议来确保电信网络（如VPLS）之间的流量自动传输。 该技术还提供了通过双归属环路协议保护和不受保护的VPLS数据流的选择性处理。

摘要： Technique for handling traffic between a specific common source node and a network element NE being part of a dual homing configuration, via a main path and an auxiliary path in the configuration, the technique comprises redirection of the traffic from one of said paths to another while the path from which the traffic has been redirected remains active, while relearn of MAC addresses which is required due to the redirection is performed without executing a MAC addresses flush operation.

摘要： Technique for protecting different telecommunication services in an Ethernet network using two different loop avoiding traffic protection protocols, by concurrently utilizing the protocols in one and the same network on different loop free logical topologies of the network. The telecommunication services are preliminarily distributed in such a manner, that the services which can be better protected by one of the two protocols and the services better protectable by the other protocol, are carried via the different topologies.

摘要： Technology for reducing bandwidth consumption in an Ethernet network, by dynamic selection of one copy of traffic services (per protection group) for transmitting to a remote Ethernet node from a multi-homing node. The dynamic selection is performed during a normal (full) working condition of the multi-homing node. In case the multi-homing node condition changes to a partially working condition, selection of the services per protection group depends on the remaining working facilities of the multi-homing node.
