Abstract: Described herein are systems, devices, techniques and products for configuration of access points in access point clustering environments. For example, access points are provided that self-discover existing access point clusters present on a single layer 2 broadcast domain or virtual local area network (VLAN). The access points may join one of the existing access point clusters or establish a new access point cluster, depending on compatibility or capacity, for example. Access point clusters that are present on a single VLAN may be distinguished based on a cluster identifier in order for multiple access point clusters to operate on the VLAN without creating a conflict. One or more criteria, such as a cluster identifier, a cluster size, a cluster version, a network latency, etc., may be used by an access point in determination of which of multiple access point clusters to join. When multiple clusters are operating on the VLAN, a supercluster may be formed.

Abstract: This invention involves a method and a device for enhanced oil-water separation and desalination in a low-pressure separator. The water-containing oil is mixed with desalted water in a countercurrent way at the entrance, wherein the desalted water accounts for 0-1% of the water-containing oil by volume. The resultant oil-water mixture then enters a T-shaped liquid-gas separator (3) for degassing treatment to quickly separate gas from the mixture. In a low-pressure separator, the oil-water mixture flows, from left to right, to a flow conditioner (4) to uniformly distribute the mixture in the transverse section, and then flows to a hydrophilic droplet agglomeration module (5) and a CPI fast separation module (6) to separate water from oil, wherein part of the separated water is discharged and the oil with a trace of water (0-0.01%) passes over a partition (18) to a deep separation segment.
