Disclosed are a RSCN method and system, a related device and a computer storage medium. The RSCN method applied to an Ethernet Node (ENode) device includes that: an RSCN message is received; and when it is determined that destination Media Access Control (MAC) contained in the RSCN message is ENode MAC, the RSCN message is distributed to a corresponding Virtual Node Port (VN_Port). The RSCN method applied to a Fiber Channel Over Ethernet (FCoE) Forwarder (FCF) includes that: network detection is performed; and when it is detected that a state to which attention is paid in a network changes, a first RSCN message is sent to an ENode device which pays attention to such a state change and succeeds in centralized notification capability negotiation with the FCF, destination MAC contained in the first RSCN message being ENode MAC. Disclosed are an ENode device, an FCF and an RSCN system.

The present disclosure is directed to a multi-level resource reservation system that obviates one or more of the problems due to limitations and disadvantages of the related art. The multi-level resource reservation system creates, or modifies existing, peer-to-peer protocol(s) to complete a continuous chain of configured ports to support QoS feature(s), e.g., bound latency and guaranteed jitter, for a data flow that traverses an arbitrary sequence of bridges, routers, and virtual links.

A system and method is provided for stabilizing a BACnet MSTP network when failures occur. The system may include at least one processor in an MSTP device configured via executable instructions included in at least one memory to communicate data expecting reply (DER) messages for field devices (e.g., HVAC, lighting, shading) onto an MSTP network for receipt by at least one IP device on an Ethernet network connected to the MSTP network via a BACnet IP/MSTP router. The processor may be configured to determine when the at least one IP device sent a DER message has become a non-communicative device. Also the processor may be configured to send a Poll for Master (PFM) message to the determined non-communicative device. In addition, the processor may be configured to drop further DER messages to the determined non-communicative device responsive to an absence of receipt of a response to the PFM message.

A system and method for network topology management includes a network controller having a control unit one or more ports coupled to the control unit and configured to couple the network controller to a plurality of switches in a network, and a memory coupled to the control unit and configured to store a topology of the switches. The topology includes a plurality of switch groups. The network controller is configured to assign a topology management module to each of the switch groups, receive a message from a switch indicating a topology change, determine when the topology change is a network link failure between switches within a first switch group that the network link failure is internal to the first switch group, and handle the network link failure when the network link failure is internal to the first switch group using the topology management module assigned to the first switch group.

Embodiments of the present invention provide utilizing a distributed network of systems for allocating and transferring resources between entities (e.g., users, institutions, or the like) by providing holds (e.g., soft or hard) on the resources, allocating the resources, and transferring the resources by utilizing allocation identifiers and/or holding pools, if needed. The use of allocation identifiers and/or holds on the resources improves upon the processing speeds and power of systems used for the resource transfers between entities.

A distributed delivery network for capacity enhancement of a communication link shared by multiple communication devices for network access service. The distributed delivery network may include one or more distributed storage devices, some of which may include at least one rotating disk storage device, a network interface, and one or more environmental sensors. Each distributed storage device may monitor data from the environmental sensor(s) and transition between an active state where messages are stored in or retrieved from the storage device, and a standby state where access is suppressed. The distributed storage devices may self-organize control operations for the distributed delivery network including message storage and retrieval and redundancy of messages, which may be determined by frequency of requests for the messages.

A system receives a request for a plurality of resources of a cloud computing system to deploy a service. The system selects a portion of the resources and determines whether the selected portion is at least partially available in one or more clusters in parallel. If available, the system reserves the available resources for a predetermined period of time. If unavailable in one of the clusters, the system releases the reserved resources after the predetermined period of time. While or after determining the availability, the system locates at least a portion of the remainder of the resources in the one or more clusters. The system allocates the reserved resources on one of the clusters and the located remainder of the resources to deploy the service and instantiates the service on the one of the clusters using the allocated resources.

A system and method is provided for identifying network links for augmentation based on potential link failures. In one aspect, the links are selected by identifying multiple shortest paths between a node pair and generating augmentation recommendations for a single link by accumulating recommendations based on multiple node pairs.

In a mobile communication system comprising a first user terminal and a second user terminal, D2D communication is radio communication directly performed between the first user terminal and the second user terminal in a frequency and a time assigned from a base station. In a time in which data is to be received from the first user terminal, when the second user terminal does not receive the data from the first user terminal, the second user terminal transmits failure notification indicating reception failure in the D2D communication to the base station.

A protocol element referred to as a secure handle is described which provides an efficient and reliable method for application-to-application signaling in multi-process and multi-computer environments. The secure handle includes an absolute memory reference which allows the kernel to more quickly and efficiently associate a network data packet with an application's communication context in the kernel.
