SYSTEMS AND METHODS FOR MULTI-LEVEL SWITCHING OF DATA FRAMES

摘要

Systems, methods and apparatus for multi-level switching in a network comprising a plurality of link-state routing areas. In some embodiments, a network device connecting at least two link-state routing areas is configured to receive a data frame from an area. The network device may be configured to determine whether the data frame is to be transmitted to a different area and to determine whether to modify at least one field of the data frame prior to transmitting the data frame based on whether the data frame is to be transmitted to a different area. The network device may be further configured to determine whether to block the data frame based on whether the data frame is to be transmitted to a different area and based on a field of the data frame.
