Abstract: Methods and systems for improved update of firmware for components in a storage system/network. A storage network comprising one or more initiator components coupled through one or more switching components to one or more target components may be updated by generating and distributing a package buffer comprising portions where each portion comprises firmware for a corresponding type of component. Switching and/or initiator components in the system locate a portion of the package buffer for each target component directly coupled to it and transmits the located, corresponding portion (comprising firmware) to each target component. Each initiator/switching component then also forwards the entire package buffer to each other switching component coupled with it and the process repeats until all components have received updated firmware.

Abstract: An electrode assembly for a vacuum interrupter is configured such that supporting members can support most of a contact electrode plate and a supporting electrode plate in an axial direction with coil conductors interposed therebetween. Accordingly, an impact generated between electrode assemblies upon a closing operation of the vacuum interrupter may be evenly distributed onto the supporting members, which may result in preventing each of the electrode plates and the coil conductors from being deformed. Also, the supporting members are inserted into the electrode plates and the coil conductors, thereby effectively preventing a current from flowing via the supporting members. In addition, the supporting member may be wide and large so as to simplify an assembly operation and reduce an assembly time.

Abstract: In one embodiment, a network processor services a plurality of queues having data using weighted round robin scheduling. Each queue is assigned an initial weight based on the queue's priority. During each cycle, an updated weight is generated for each queue by adding the corresponding initial weight to a corresponding previously generated decremented weight. Further, each queue outputs as many packets as it can without exceeding its updated weight. As each packet gets transmitted, the updated weight is decremented based on the number of blocks in that packet. If, after those packets are transmitted, the decremented weight is still positive and the queue still has data, then one more packet is transmitted, no matter how many blocks are in the packet. When a decremented weight becomes negative, the weights of the remaining queues are increased to restore the priorities of the queues as set by the initial weights.
