Leaf nodes of a tree structure, also having a root node and intermediate nodes, communicate with endpoints via access networks and store mappings from permanent virtual IP (VIP) addresses for the endpoints to physical IP (PIP) addresses for the endpoints on the access networks. The root node and intermediate nodes store pointers for the endpoints' leaf nodes and associated access networks. When a connection setup request (CSR) for a destination endpoint is received from a corresponding node, the receiving leaf node passes the CSR up through the tree structure to a lowest common ancestor (LCA) node for the receiving leaf node and one or more destination leaf nodes associated with the destination endpoint. The LCA node uses its pointers to pass the CSR down towards the one or more destination leaf nodes, which use the corresponding VIP-to-PIP mappings to forward the CSR to the destination endpoint.

Locator lookup-based, low-latency, multi-access IP mobility

Network-based, unsupervised classifiers are provided. The classifiers identify both known and unknown attacks aimed at industrial networks without the need to have a priori knowledge of known malicious attack patterns.

This disclosure generally discloses an anchor mobility mechanism. The anchor mobility mechanism is configured to support migration of flows between mobility anchors within a wireless communication system. The anchor mobility mechanism may be configured to support migration of flows between mobility anchors within a wireless communication system in a highly seamless manner. The anchor mobility mechanism may be configured to support migration of a flow of a wireless device between mobility anchors within a wireless communication system using functions performed by a control element (CE) and one or more forwarding elements (FEs) within the data plane of the flow of the wireless device. The functions may include identifying a time at which to initiate migration of the flow, initiating migration of the flow based on identification of the time at which to initiate migration of the flow, or the like, as well as various combinations thereof.

In a data processing system, a received data stream comprises a plurality of tuples having respective key values. The received data stream is separated into portions that are delivered to respective ones of a first set of servers in a manner that permits different tuples having the same key value to be processed by different servers of the first set. For each distinct key value, each of at least a subset of the servers of the first set maintains a corresponding partial key result based on one or more of the tuples having that key value that are received by that server. The partial key results are periodically delivered from the servers of the first set to servers of a second set of servers in a manner that ensures that different partial key results having the same key value are processed by the same server of the second set.

Data stream load balancing utilizing multiple sets of servers

Various embodiments provide a method and apparatus for allocating resources to applications (e.g., application processes) using pre-provisioned resource configurations (e.g., VMs or containers) that are based on clustered historical resource usage data. In particular, the set of pre-provisioned resources required to support elasticity in a set of applications is reduced by determining a subset of pre-provisioned resource configurations that are able to be reused across multiple applications. A pre-provisioned resource configuration being based on a determined dominant center for the resource cluster associated with the pre-provisioned resource configuration.

A method and apparatus for substantially minimizing overhead over-provisioning costs in machine configurations is disclosed. The method involves the steps of: clustering a plurality of given machine configurations into a quantity of clusters less than or equal to a pre-specified amount; determining a respective dominant provisioning machine configuration for each cluster of the quantity of clusters; and determining an overall over-provisioning resource cost associated with the respective quantity of clusters and associated respective dominant provisioning machine configurations; and assigning to a mapping function the respective associated dominant provisioning machine configuration of each respective cluster of the quantity of clusters as the target for the given machine configurations of each respective cluster of the quantity of clusters. The method for substantially minimizing overhead over-provisioning costs in machine configurations provides advantages over systems known in the art by allowing minimization of average overhead due to over-provisioning costs as well as minimizing the maximum overhead due to over-provisioning costs.
