摘要： A control information exchange system includes a sender device coupled to a receiver device and including a sender device application that periodically generates and transmits control packets that are directed to the receiver device. A control packet engine in the sender device receives a first control packet from the sender device application, performs a hashing operation on the first control packet to generate a first hash value, stores the first hash value in a sender device database, and transmits the first control packet to the receiver device. When the control packet engine subsequently receives a second control packet from the sender device application, it performs the hashing operation on the second control packet and, in response that hashing operation generating the first hash value, it transmits the first hash value to the receiver device to indicate the second control packet was duplicative of the first control packet.

摘要： Embodiments of the present invention include systems and methods for preventing or reducing traffic losses of data. If an information handling system, such as a switch or router, in a network attempts to install route information in the data store of the information handling system and has a failure or a potential failure, the information handling system may take one of several options or combinations thereof. In embodiments, the information handling system may not advertise the route information. In embodiments, the information handling system may send a route withdrawal message to one or more peer information handling systems to remove that system from routing determinations involving the route information. Alternatively, the information handling system may advertise the route prefix with a high metric to indicate that the system is a non-preferred forwarder for data intended for a destination associated with the route information.

摘要： A Power over Ethernet (PoE) adaptive powering system includes a powered device that identifies a first operating mode in which the powered device is currently operating, determines a first power amount that is required to enable the first operating mode in which the powered device is currently operating, and transmits a first power amount request message that requests the first power amount via a power/data connection. The adaptive PoE powering system also includes a powering device that is connected to the powered device via the power/data connection, and that receives the first power amount request message via the power/data connection, and transmits the first power amount via the power/data connection to the powered device.

摘要： An STP link selection system includes a first and second designated switch devices providing different paths to a root switch device. A non-designated switch device receives a first communication from the first designated switch device identifying a first root path cost for a first link to the first designated switch device and a first designated switch device identifier, and designates the first link as an active link for communications to the root switch device. The non-designated switch device subsequently receives a second communication from the second designated switch device identifying a second root path cost for a second link to the second designated switch device that is equal to the first root path cost, and a second designated switch device identifier that is lower than the first designated switch device identifier. In response, the non-designated switch device designates the second link as a non-active link upon which communications are blocked.

摘要： An STP link selection system includes a designated switch device that receives a first communication that indicates that a first link provided to a non-designated switch device from a first port is available and, in response, automatically assigns the first port with a primary port priority. The designated switch device then subsequently receives a second communication that indicates that a second link provided to the non-designated switch device via a second port is available and, in response, the second port is automatically assigned with a secondary port priority. The designated switch device identifies a first port identifier that is based on the primary port priority to the non-designated switch device and, based on the first port identifier relative to a second port identifier that is based on the secondary port priority, the non-root switch device transmits communications via the first link and blocks communications via the second link.
