Abstract: A multi-node cluster is configured for credential management. A method commences by retrieving a super-user credential from a credential record stored in a location accessible to the cluster, then propagating the super-user credential to a set of nodes in the multi-node cluster. A credential creating processes is invoked on at least some of the set of nodes. Application-level credential access can be implemented in a multi-cluster environment by carrying-out an exchange that passes credentials between a first cluster and a second cluster over a secure channel. A protocol is observed whereby one or more applications running on the first cluster receive new credentials for accessing the second cluster from the credential serving process after the credential creating process creates the new credential.

Abstract: Techniques for universal cache management are described. In an example embodiment, a plurality of caches are allocated, in volatile memory of a computing device, to a plurality of data-processing instances, where each one of the plurality of caches is exclusively allocated to a separate one of the plurality of data-processing instances. A common cache is allocated in the volatile memory of the computing device, where the common cache is shared by the plurality of data-processing instances. Each instance of the plurality of data-processing instances is configured to: indentify a data block in the particular cache allocated to that instance, where the data block has not been changed since the data block was last persistently written to one or more storage devices; cause the data block to be stored in the common cache; and remove the data block from the particular cache. Data blocks in the common cache are maintained without being persistently written to the one or more storage devices.

Abstract: Techniques are described for selecting paths in accordance with service level agreements. For example, spoke and hub routers may advertise routes associated with virtual routing and forwarding (VRF) instances mapped to service level agreements (SLAs). A virtual route reflector of an intermediate router may receive route advertisements and may add respective path communities associated with particular links selected based on link state measurements in accordance with the SLAs. The hub or spoke routers may receive the route advertisements including a respective path community and install the selected path as a next-hop for a given SLA. In this way, spoke and hub routers may forward traffic on links that satisfy particular SLAs such that Quality of Experience (QoE) for an application may be restored or improved.

Abstract: A request is received for executing the load test on the application. The request includes a script and a property file. In response to the request, containers are created on a hardware host. Each of the containers isolate mutually exclusive subsets of hardware resources of the hardware host based on namespaces. A client and a plurality of servers are created in the containers. Only one of the client or the servers reside in each of the containers. The client and the servers are designated to communicate with the application. The load test is performed on the application while each of the client and the servers use the subset of the hardware resources isolated by a respective namespace. The property file is input to the script and the script instructs the client on how to control execution of the load test by the servers. The containers, the client and the servers are removed from the hardware host after the load test has completed.

Abstract: A method includes receiving a change in a primary configuration of a primary storage node while the primary storage node is operational, wherein primary data stored in the primary storage node is to be backed up as backup data in a backup storage node. The method includes locating at least one identifier in the change that identifies the primary storage node. The method includes replacing the at least one identifier in the change that identifies the primary storage node with an identification of the backup storage node to create an updated configuration change. The method includes updating a backup configuration of the backup storage node based on the updated configuration change.

Abstract: Techniques are described for establishing a segment routed label switched path (LSP) regardless of whether a router along the shortest path is not enabled for segment routing. For example, a resource reservation LSP (e.g., a resource reservation protocol (RSVP) LSP) is established across the router that is not enabled for segment routing, such that the segment routed LSP may be established to tunnel through the resource reservation LSP. For example, when a centralized controller receives a request to establish a path using segment routing, one or more routers along the shortest path may not be enabled for segment routing. Instead of rejecting the request to establish the segment routed LSP in response to determining that one or more routers in a selected path are not enabled for segment routing, the controller may establish a resource reservation LSP to tunnel around the router that is not enabled for segment routing.

Abstract: A network monitoring system compares gathered network information with path information. The comparison between gathered network information and path information provides traceability of automatic and dynamic rerouting function of network and makes it possible to understand the relation between root cause and observed problems. The combined monitoring of data plane with control plane enables identification of the original failure point where behavior is changing though routing failure is propagated around. This will allow the identification of network issues that may lead to service outages and impairments as well as alerting of issues affecting customer satisfaction, and is effective to reduce MTTD (Mean Time To Detect)/MTTR (Mean Time To Repair) and increase service availability in all markets.

Abstract: A method, system, and computer program for high-availability database systems. The method commences by replicating (e.g., from a first server to a second server) a data structure having entries describing resource locks and client states. The replication can be performed to any number of servers. Upon detecting a failure of a connection between the first server and a client to which the first server is connected, the system establishes a new connection between the second server and the client by updating the replicated data structure to describe new connection between the second server and the client and updating the entries of the replicated data structure to reflect the new connection and the then current aspects of the resource locks and client states. The client can be a database instance, and the act of replicating can be accomplished using a broadcast channel. The servers can be organized in a computing cluster.
