  • Patent number: 10728139
    Abstract: Methods and apparatuses for building a programmable dataplane are described. Specifically, the programmable dataplane can work on a list of identifiers, such as those part of OpenFlow 1.5. Specifically, the programmable dataplane can be built by creating a virtual network graph at a controller node using binary identifiers such that a node is broken into an n-ary tree and the tree has 1×2 or 1×1 nodes.

  • Patent number: 8399677
    Abstract: The invention provides a method for the preparation of fentanyl comprising: (a) reacting 4-piperidone hydrochloride monohydrate with aniline in presence of reducing environment to produce 4-anilinopiperidine (4-AP), (b) reacting the 4-AP as obtained from step (a) with phenethyl halide under reflux conditions in highly alkaline medium to give 4-anilino-N-phenethylpiperidine, and (c) converting the 4-anilino-N-phenethylpiperidine to fentanyl by reacting with propionyl chloride in presence of halogenated hydrocarbons, then isolating fentanyl by solvent extraction and purifying by crystallization from petroleum ether at a temperature ranging from 60-80° C.
