  • Patent number: 9832040
    Abstract: According to an example, in a method for redirecting virtual machine traffic a virtual switch may be implemented in a physical server. In addition, a packet sent from a first virtual machine to a second virtual machine may be detected, in which the first virtual machine and the second virtual machine are in the same virtual local area network (VLAN), and in which the packet has a first VLAN label that identifies the VLAN. Moreover, the first VLAN label may be replaced with a second VLAN label in the packet, in which the second VLAN label differs from the first VLAN label, and the packet may be sent to an uplink switch, in which the uplink switch may send the packet to a network security module.

  • Patent number: 9698793
    Abstract: A method for upgrading a programmable logic device (PLD) in a network element is provided. The method includes writing PLD configuration data to a nonvolatile memory and directing a signal control device external to the PLD to hold system control signals in the network element at a predefined state irrespective of direction by the PLD. The method includes loading the PLD configuration data from the nonvolatile memory into a PLD configuration memory in the PLD, while the signal control device holds the system control signals at the predefined values. The method includes directing the signal control device to release the holding the system control signals, so that the PLD directs the system control signals, responsive to completion of the loading the PLD configuration data into the PLD configuration memory. A network element is also provided.
