Some embodiments provide a method for a network controller that manages multiple managed forwarding elements (MFEs) that implement multiple logical networks. The method stores (i) a first data structure including an entry for each logical entity in a desired state of the multiple logical networks and (ii) a second data structure including an entry for each logical entity referred to by an update for at least one MFE. Upon receiving updates specifying modifications to the logical entities, the method adds separate updates to separate queues for the MFEs that require the update. The separate updates reference the logical entity entries in the second data structure. When the second data structure reaches a threshold size in comparison to the first data structure, the method compacts the updates in at least one of the queues so that each queue has no more than one update referencing a particular logical entity entry. |

Systems and methods for proxying encrypted traffic to protect origin servers from internet threats
This document describes, among other things, systems and methods for more efficiently resuming a client-to-origin TLS session through a proxy layer that fronts the origin in order to provide network security services. At the time of an initial TLS handshake with an unknown client, for example, the proxy can perform a set of security checks. If the client passes the checks, the proxy can transmit a ‘proxy token’ upstream to the origin. The origin can incorporate this token into session state data which is passed back to and stored on the client, e.g., using a TLS session ticket extension field, pre-shared key extension field, or other field. On TLS session resumption, when the client sends the session state data, the proxy can recover its proxy token from the session state data, and upon successful validation, bypass security checks that it would otherwise perform against the client, thereby more efficiently handling known clients. |

Block-diagonalization based beamforming
Embodiments provide an innovative solution for finding the beamforming vectors which are based on classical BD.
