Abstract: Disclosed are a system, method and devices for simultaneous MACsec key agreement (MKA) negotiation between the devices. The present application controls a basic TLV message exchange between supplicant and authenticator in case of race condition to establish the secure association key (SAK) channel. The present application by controlling a basic TLV message exchange enables to establish a secure channel in race condition and achieves a high reliability of the product as this makes product launch MACsec services quickly and available for the service. Accordingly, when both sides (two supplicants) exchange hello with basic TLV at the same time, triggering the race condition, drops first message from the authenticator at supplicant and update the peer MN and the supplicant will not send reply. The authenticator when send next message (basic+potential peer TLV) with peer MN incremented by 1, the supplicant will respond with incremental message with live peer TLV.

Abstract: Embodiments of this application disclose a method for parsing a service platform address by a server. The server receives a DNS parsing request sent by a terminal, the DNS parsing request including a to-be-parsed domain name. The server then obtains target IP information of the terminal based on the DNS parsing request. When the target IP information has a corresponding target user-defined line, the server obtains a preset first parsing record based on the target user-defined line. The server then sends to the terminal a first IP address corresponding to the to-be-parsed domain name based on the preset first parsing record. As such, a corresponding IP address range can be defined using a user-defined line, so that a terminal within the IP address range can obtain a specific IP address corresponding to an access domain name, and provide a service to a user within a more accurate range.

Abstract: A prosthetic mitral annuloplasty ring includes a wire, an adjustment member for changing a length of the wire and a jacketing annulus for adjusting a radial dimension of the mitral valve annuloplasty ring. The jacketing annulus is sleeved over the wire and forms, together with the adjustment member, a shape matching that of a native mitral valve annulus. After the prosthetic mitral annuloplasty ring is implanted by suturing in a conventional surgical procedure and the patient's heart starts to beat again, the adjustment member can be connected to the delivery device and the wire length therein can be adjusted by a rotating operation of the delivery device so that the mitral valve annuloplasty ring will be expanded or contracted until the prosthetic mitral annuloplasty ring perfectly fits the native mitral valve annulus in shape, effectively avoiding the problem of incomplete mitral leaflet coaptation.
