Facilitation of idle mode cell reselection for 5G or other next generation network
In multicarrier networks mobile devices can be distributed amongst carriers based on different criteria. However, prioritization may cause certain devices to end up on a carrier that is not optimal for the network. When there is a deployment of different types of cells (e.g., macro cells, small cells, etc.), the cells can use the same frequency. Consequently, a priority value contained within a system information broadcast message can override the mobile default cell transition procedures and thus select a neighboring cell based on additional criteria. Thus, small cells can be deployed to offload traffic from macro cells in spite of the small cells and macro cells operating in the same frequency band. |

Updating no sync technique for ensuring continuous storage service in event of degraded cluster state
An Updating No Sync (UNS) technique ensures continuous data protection for content driven distribution of data served by storage nodes of a fault tolerant cluster in the event of a degraded cluster state. A storage service implemented in each node includes one or more slice services (SSs) configured to process and store metadata describing the data served by the storage nodes and one or more block services (BSs) configured to process and store the data on storage devices of the node. A bin assignment service may coopt one or more healthy BSs to temporarily store updates of data and metadata received at the SS while the cluster is in the degraded state as an overflow data path (hence the term “Updating No Sync,” which denotes updating without synchronizing, i.e., not distributing the data within the cluster, but only accumulating an overflow of SS information). Once the cluster is no longer degraded, the accumulated overflow SS information at the BSs may be synchronized back to restored BSs, i.e., according to write path determination in the absence of node failure/unavailability. |

Security system with adaptive parsing
A security system protecting a monitored system (e.g., a database server) is configured to self-update (extend) a statement/command parser grammar, dynamically. To accomplish this, the security system uses the monitored system itself as a syntax validator (on the parser's behalf), and without requiring any changes or modifications to the monitored server. In one embodiment, the security system comprises a protocol analyzer and the parser. The protocol analyzer extracts a statement/command from a received request and passes it to the parser. If no parser syntax error is found, the statement/command is validated against a security policy. If a parser syntax error occurs, however, the system examines a response from the monitored system to determine whether the parser syntax error is a “false positive.” If so, the parser then self-extends its own grammar automatically to correct for the parser syntax error. Once its grammar is updated, the parser is then able to process the original request. |
