Abstract: In one embodiment, a system includes a switch that has a processor and logic integrated with and/or executable by the processor, the logic being configured to create a message indicating addition, modification, or deletion of a static flow in a software defined network (SDN), wherein the static flow includes the switch and at least one other device in the SDN, and send the message to a SDN controller in a SDN-formatted structure. In another embodiment, a method includes creating a message, using a switch, indicating addition, modification, or deletion of a static flow in a SDN, wherein the static flow includes the switch and at least one other device in the SDN, and sending the message to a SDN controller in a SDN-formatted structure. Other systems and methods for reporting static flows to a SDN controller in a SDN are described according to more embodiments.

Abstract: A system for PIM vLAG fast link failover recovery includes a first vLAG switch connected to a second vLAG switch by an ISL. The first vLAG switch is connected to an upstream network device by a failed link and the second vLAG switch is connected to the upstream network device by a functional link. To recover from the failed link, the first vLAG switch transmits a ROUTEUPDATE message to the second vLAG switch upon the ISL that instructs the second vLAG switch to receive data traffic from the upstream network device and forward the data traffic to the first vLAG switch upon the ISL.

Abstract: In one embodiment, a system includes a software-defined network (SDN) controller including a processor and logic integrated with and/or executable by the processor, the logic being configured to: receive a port addition indication that a logical port is configured on a switching device, the switching device being connected to the SDN controller and a second device, wherein the logical port represents a link aggregation group (LAG) that includes at least two links between the switching device and the second device, and derive and maintain a logical index for all logical ports in software-defined switching devices connected to the SDN controller based on logical port identifiers thereof.

Abstract: An OpenFlow switching device of an OpenFlow network sends a message including a flow rule received from a first OpenFlow controller device currently active within the OpenFlow network to a second OpenFlow controller device also currently active within the OpenFlow network. As such, the second OpenFlow controller device stays in synchronization with the first OpenFlow controller device. Upon a third OpenFlow controller device becoming newly active within the OpenFlow network, the OpenFlow switching device sends a message including flow rules of the switching device's flow table to the third OpenFlow controller device. As such, the third OpenFlow controller device becomes immediately up-to-date with respect to this flow table.

Abstract: Disclosed is a method for producing partially purified extracellular metabolite preparation from the probiotic bacterial strain Bacillus coagulans SBC-37 (Deposited in the Microbial Type Culture Collection and Gene Bank as strain number MTCC 5856) exhibiting 99% genetic homology with the known bacterial strains Bacillus coagulans ATCC 31284, Bacillus coagulans NBRC 3887 and Bacillus coagulans ATCC 7050. Also disclosed is the anti-microbial profile of said extracellular metabolite preparation against a panel of microbial pathogens, including synergistic anti-microbial effects of preparation when combined with a synergistic preservative blend comprising from about 61% w/w of thymol, about 38% of monolaurin and about 1% w/w of magnolol obtained from supercritical fluid extracts of Magnolia officinalis. The extracellular metabolite preparation alone or the combination of said extracellular metabolite preparation and preservative blend also inhibits microbial biofilm formation in a synergistic manner.

Abstract: Embodiments of the invention relate to synchronizing multicast route entries in a system. One embodiment includes a system with a first module that synchronizes a group membership and sets a router processing flag based on an interface where a packet is received. A second module receives the router processing flag and information based on the synchronized group membership from the first module and creates multicast route entries based on processing the information and the router processing flag even on a non-designated router (DR) interface.

Abstract: Embodiments of the invention relate to forwarding traffic for link aggregation groups in a system. One embodiment includes a system with a first module that receives a packet and synchronizes a group membership based on the packet. A second module receives the synchronized group membership from the first module and creates link aggregation group (LAG) entries for a primary switch and a secondary. A router receives join requests from the second module for adding a first interface link and a second interface link to the router. A source transmits traffic for the LAG. The second interface link is placed in a pruned state based on a protocol independent multicast (PIM) assert message received from the second module by the primary switch and the secondary switch. The secondary link forwards traffic in the pruned state to an access switch upon the primary link failing.
