  • Partitioning a network into multiple switching domains
    Patent number: 9237072
    Abstract: To partition a distributed fabric system, at least one system port is allocated to each switching domain of multiple non-overlapping switching domains in a distributed fabric system. Multiple different look-up tables are produced, wherein each look-up table corresponds to a different switching domain of the multiple non-overlapping switching domains in the distributed fabric system. Each system port is associated with the look-up table of the multiple look-up tables that corresponds to the switching domain to which that system port is allocated. The look-up table associated with each system port has at least one table entry for each other system port allocated to the same switching domain as that system port.

  • Partitioning a network switch into multiple switching domains
    Patent number: 9042229
    Abstract: A distributed fabric system includes multiple switches coupled to a cell-based switching fabric. A logical system port that is globally unique within the distributed fabric system is mapped to each physical network port in the distributed fabric system. To partition the system into multiple non-overlapping switching domains, each system port is associated with a look-up table having at least one table entry for each other system port to be allocated to the same switching domain as that system port. Each switch that receives a packet over a given system port is limited to switching the packet to only those other system ports for which the look-up table associated with the given system port has a table entry.
