摘要： A method and a multi-switch architecture include learning a media access control (MAC) address at a first switch in a multi-switch architecture; storing the MAC address in a forwarding database of the first switch; transmitting a data frame to one or more switches in the multi-switch architecture via inter-switch connectivity between the first switch and the one or more switches, wherein the data frame is created to enable the one or more switches to learn the MAC address therefrom; learning the MAC address from the data frame at the one or more switches; and storing the MAC address in a forwarding database for each of the one or more switches. This further includes transmitting the data frame via ports and queues in the inter-switch connectivity that are separate from ports and queues in a data path between the first switch and the one or more switches to avoid data path interference.

摘要： Line cards in a multi-slot network element utilize load balancing systems and methods for synchronizing learned Media Access Control (MAC) addresses therebetween. It is an objective of the load balancing systems and methods to enable high data rate scalability between line cards in a distributed system while preventing adverse effects on packet traffic. The load balancing systems and methods include inter alia MAC address updates between data path devices (e.g., network processors, application specific integrated circuits, etc.) using data frames and a hash-based time slot strategy ensuring MAC address updates are distributed over time as opposed to large scale, singular events.
