Abstract: A method for dynamically adding a new channel to a group of virtually concatenated channels carrying traffic to a network element (NE) of a synchronous network. By this method if a delay associated with the new channel is longer than a delay associated with the group of virtually concatenated channels then traffic received along the group of virtually concatenated channels is delayed until the group of virtually concatenated channels and the new channel are time-aligned, and then the new channel is added to the group. If the delay associated with the new channel is shorter than the delay associated with the group of virtually concatenated channels then traffic in the new channel is delayed until the new channel and the group of virtually concatenated channels are time-aligned, and then the new channel will be added to the group.

Abstract: A method for enabling communication between synchronous network elements, which is adapted to support dynamic application of various types of changes, such as adding a new channel, to an aligned group of virtually concatenated channels carrying communication traffic between these elements.

Abstract: 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.
