A method for assigning identifiers to switches in a stack includes detecting, by a switch, a terminal identifier stored in an optical module that is connected to a stack port of the switch, where the optical module is at one end of an optical cable; and if a condition is met, assigning, by the switch, identifiers to N stackable switches along a direction starting from the switch to another switch connected to the stack port, where the condition includes: a value of the terminal identifier is a specified value, and N is greater than or equal to 2. According to this application, an efficiency of assigning the identifiers to the switches in a stack can be improved.

A method is provided that uses a consistent hashing technique to dispatch incoming packets in a stable system prior to adding of a node. The method uses a hash table and assigns hash buckets in the table to each network node. A set of fields in each incoming packet is hashed and is used to identify the corresponding hash bucket. The packets are then dispatched to the network nodes based on the nodes' hash buckets. During an observation period, the method identifies the ongoing sessions by creating a bit vector table that is used to identify the old and new sessions during a re-dispatching period. The method uses the consistent hashing method and the probabilistic method dispatch the incoming packets such that each packet that belongs to an old session is dispatched to the same old node that has been processing the other packets of the session.

A method and apparatus for remotely updating firmware in batches, and a computer-readable storage medium. Wherein the method is applied to a DHCP server connected with a Baseboard Management Controllers (BMC) of each server node. The DHCP server assigns IP addresses to each server node in advance, and records a BMC MAC address of each server node at the same time. When detecting that a firmware version to be matched stored in itself is updated, authorized server nodes and corresponding BMC IP addresses are determined on the basis of each BMC MAC address and authorization state. The firmware version of the corresponding authorized server nodes is read according to the BMC IP address of each authorized server, and a plurality of servers to be upgraded is determined by comparing the firmware version of each authorized server node with the firmware version to be matched.

Methods and apparatus for resource optimization in Internet-of-Things (IoT) networks are presented. For instance, the disclosure presents an example method executed by a network node (106) in an IoT system (100). In some embodiments, the example method includes predicting (202) a likelihood that a future event will be detected by one or more IoT devices (102) in the IoT system (100) under different potential resource allocation and IoT device settings. The predicting (202) is conducted subject to resource availability constraints in some examples. In addition, the example method includes, based on the predicting (202), adapting (204) at least one of resource allocation and IoT device settings in the IoT system (100) for the future time. This adapting (204) is conducted such that the likelihood that the future event will be detected is maximized under the resource availability constraints according to a target optimization function.

A processor initiates an execution of a network driver in a first node comprising a master node of a plurality of nodes in a switchless network. The network driver configures the plurality of nodes and service level in the switchless network by transmitting management datagrams from the master node, wherein the management datagrams include an attribute that allows the management datagrams to be propagated among the plurality of nodes of the switchless network without being terminated at host channel adapters of the plurality of nodes.

A server system comprising storage devices, processing devices and a storage fabric all operating according to a storage fabric protocol. The storage fabric comprises a plurality of individual switches having a modular design from which an overall switch is built, and the individual switches have individual respective configuration settings which determine which processing devices are allocated to use which of the storage devices. The system comprises an API enabling a software control function to configure the overall switch. The API is operable to receive from the control function an overall mapping of the storage devices to the processing devices instead of requiring the individual configuration settings of each of the individual switches to be specified by the control function, the API being configured to convert the overall mapping into the individual configuration settings of the individual switches to produce the overall mapping.
