  • Patent number: 8139510
    Abstract: A method for supporting dynamic configuration changes comprises receiving a message from a current root bridge, comparing a bridge media access control (MAC) address of a receiving port to a bridge MAC address of the received message, if the bridge MAC addresses are the same, then comparing a current priority value with a previous priority value of the current root bridge, determining if the receiving port is a qualified root port, and if the port is a qualified root port, then returning a superior designated message to execute an RSTP calculation.

  • Publication number: 20110216672
    Abstract: An embodiment includes a method of minimizing the delay in convergence time for a complex STP topology following a topology change in the network system in the spanning tree protocol (STP) standard, including: receiving, by a root port of a first bridge, a data message that includes identification of a current root bridge and a priority value of the current root bridge; receiving, by a second port of the first bridge, a second data message from a second bridge; and if a message age timer of the first bridge has less than a limiting message age time value remaining before expiry, then blocking a reply, by the second port of the first bridge, to the second data message from the second bridge.

  • Patent number: 7720011
    Abstract: In an embodiment, a method for supporting dynamic configuration changes, includes: receiving a message from a current root bridge; comparing the bridge media access control (MAC) address of a receiving port to the bridge MAC address of the received message; if the bridge MAC addresses are not the same, then comparing a current priority value to a previous priority value of the current root bridge; if the current priority value is inferior, then determining if the port receiving the message is a qualified root port; and if the port is a qualified root port, then returning a superior designated message to permit each bridge to execute a rapid spanning tree calculation for use in a dynamic configuration change.
