    摘要: A method, apparatus and system for medium access control is provided. Time slots configured to include mini slots at the beginnings thereof. Devices are assigned time slot, mini slot combinations as transmission opportunities. A device can attempt to use a transmission opportunity when it has a packet to send, by beginning data transmission in its assigned slot and mini slot and potentially continuing the transmission up until the end of the assigned slot. If another device is already transmitting in the assigned slot, the device refrains from using its transmission opportunity. Higher priority devices can be assigned transmission opportunities corresponding to earlier mini slots within a slot. In some embodiments, multiple devices can be assigned the same transmission opportunity and a collision detection mechanism can be employed. In some embodiments, all devices detect if a slot is idle and advance the beginning of the next slot upon such detection.

    摘要: The disclosed apparatuses and methods are directed to embedding of virtual links in an optical network. The method comprises: receiving an adaptation request for a virtual link within a virtual network embedded on an optical substrate network; generating a plurality of candidate embeddings based on a topology of the substrate network and a current embedding of the virtual link, each candidate embedding satisfying the adaptation request; determining a total cost of each candidate embedding based on a disruption cost of the candidate embedding; and selecting, as a new embedding, a candidate embedding from the plurality of candidate embeddings in accordance with the determined total cost of the selected candidate embedding.

    摘要: A hybrid electronic optical chip has a first photonic element with which a first diode is associated, a second photonic element with which a second diode is associated and a common electrical driver connected to the first and second diodes by a common electrical connection with opposite polarity. The electrical driver generates a common electrical drive signal divided in time into first and second drive signal components for independently driving the first and second photonic elements through the common electrical connection.
