  • Publication number: 20180083863
    Abstract: A method and apparatus of a network element that updates an interface list of a multi-link group of a network element is described. In an exemplary embodiment, a network element receives an indication that the interface list for the multi-link group on a network element is to change. In addition, the interface list includes a first set of interfaces. The network element further includes an address table having a plurality of address entries, where each of the plurality of address entries includes an address, a multi-link nexthop, and a tag group reference. The tag group reference references an entry in a tag group table, where a tag group entry includes a tag group identifier and a tag group set of interfaces. The network element further receives a second set of interfaces. The network element additionally updates the interface list for the tag group entry to include a second set of interfaces. Furthermore, the network element transmits data with the multi-link group using the second set of interfaces.

  • Publication number: 20160122213
    Abstract: Methods of controlling a nitrification reaction in a biological nitrogen removal reactor to favor partial nitrification of ammonia to nitrite instead of complete oxidation of ammonia to nitrate are disclosed. In some embodiments, the methods include the following: maintaining a pH in the reactor within a range that promotes growth of ammonia oxidizing bacteria; maintaining a concentration of dissolved oxygen in the reactor within a range that limits the ammonia oxidizing bacteria from completing nitrification; selecting an operational solids retention time within a range suitable for maintaining increasing concentrations of the ammonia oxidizing bacteria in the reactor while reducing concentrations of nitrite oxidizing bacteria in the reactor; and increasing a concentration of free ammonia in the reactor thereby inhibiting growth of the nitrite oxidizing bacteria in the reactor.
