Abstract: A system for load management in a shared address networking architecture includes a primary point-of-presence (POP) group of servers configured to serve content of a domain and that are each reachable at an address of a first IP address block and a secondary PoP group of servers configured to serve the content of the domain and that are each reachable at an address of a second IP address block. The system further includes a traffic management agent configured to reduce a total volume of incoming requests received by the primary PoP group for a period of time following a return of a first server in the primary PoP group of servers to an online state by selectively directing a first percentage of the incoming requests to the second IP address block instead of the first IP address block.

Abstract: A flow rate control method for solicited data communications includes receiving, at a first node of a communications network, a request-to-send (RTS) signal from a second node of the communications network, the RTS signal indicating a size of a solicited data transmission of the second node, determining, by the first node, whether a rate-limiting counter is above zero, wherein the rate-limiting counter is programmed to increase at a programmed rate and in response to the rate-limiting counter being above zero, scheduling, by the first node, a clear-to-send (CTS) signal to be sent from the first node to the second node over the communications network, and subtracting, by the first node, a value corresponding to the size of the solicited data transmission of the second node from the rate-limiting counter.

Abstract: A packet cache system includes a cache memory allocator for receiving a memory address corresponding to a non-cache memory and allocated to a packet, and associating the memory address with a cache memory address; a hash table for storing the memory address and the cache memory address, with the memory address as a key and the cache memory address as a value; a cache memory for storing the packet at a location indicated by the cache memory address; and an eviction engine for determining one or more cached packets to remove from the cache memory and place in the non-cache memory when occupancy of the cache memory is high.

Abstract: A method and device for reducing measurement error/s is provided. The method receives a file by an engineering tool from a system configurator tool and parses the file to identify a value associated with a transformer setting for a process bus device. The method fetches information from installation data to identify the value when the value is not identified in the file and stores the value in the engineering tool when the value is identified in the file or in the information. The method marks the value as a missing value to visually notify a technician when the value is not identified in the information or the file. The method publishes the value at a remote database for process bus subscriber device/s.

Abstract: Aspects of the disclosure are directed to supporting time synchronization across a datacenter network with greater accuracy. The time synchronization includes both software based and hardware based time synchronization mechanisms to provide more precise time synchronization across various nodes in the datacenter network. The software based mechanism can provide the initial coarse time synchronization while the hardware based mechanism can provide the subsequent finer time synchronization.

Abstract: Aspects of the disclosure are directed to a packet cache eviction engine for reliable transport protocols of a network. The packet cache eviction engine can manage on-chip cache occupancy by evicting lower priority packets to off-chip memory and ensuring that higher priority packets are kept on-chip to achieve higher performance and lower latency in processing packets in the network.

Abstract: An application specific integrated circuit (ASIC) is provided for reliable transport of packets. The network interface card may include a reliable transport accelerator (RTA). The RTA may include a cache lookup database. The RTA may be configured to determine, from a received data packet, a connection identifier and query the cache lookup database for a cache entry corresponding to a connection context having the connection identifier. In response to the query, the RTA may receive a cache hit or a cache miss.

Abstract: Versions of an application are managed by receiving a request for a version of an application, retrieving, responsive to the received request, a version of a master application component based at least in part on version data that associates a version of the master application component with the version of the application, retrieving a relationship operable to relate the version of the master application component with a corresponding version of a first component on which the master application component depends for a function of the application, retrieving the corresponding version of the first component, responsive to the retrieving of the relationship, assembling the version of the application based at least in part on the retrieved version of the master component, the retrieved relationship, and the retrieved first component, and providing for an execution of the assembled version of the application.

Abstract: Aspects of the disclosure are directed to high performance connection cache eviction for reliable transport protocols in data center networking. Connection priorities for connection entries are determined to store the connection entries in a cache based on their connection priority. During cache eviction, the connection entries with a lowest connection priority are evicted from the cache. Cache eviction can be achieved with low latency at a high rate.

Abstract: Techniques of remote computing resource access using sharable links are disclosed herein. One example technique includes receiving, at a security portal of a private network, an access request from a client device of a user for accessing a virtual machine (“VM”) on the private network via a public network. The technique can then include retrieving a copy of a configuration file corresponding to the virtual machine according to the VM identifier in the access request and accessing the virtual machine according to operating parameters in the retrieved copy of the configuration file to generate an execution result. The technique can further include transmitting, from the security portal, the execution result to the client device of the user via the public network, thereby shielding, with the security portal, the virtual machine on the private network from actions initiated via the public network.
