Abstract: Example implementations relate to determining whether network invariants are violated by flow rules to be implemented by the data plane of a network. In an example, a verification module implemented on a device receives a flow rule transmitted from an SDN controller to a switch, the flow rule relating to an event. The module determines whether the flow rule matches any of a plurality of network invariants cached in the device. If determined that the flow rule matches one of the plurality of network invariants, the verification module determines whether the flow rule violates the matched network invariant. If determined that the flow rule does not match any of the plurality of network invariants, the verification module (1) reports the event associated with the flow rule to a policy management module, (2) receives a new network invariant related to the event from the policy management module, and (3) determines whether the flow rule violates the new network invariant.

Abstract: An improved database-management system determines that a near-capacity leaf page of its database index must be split into multiple pages in order to store newly added index entries. The system determines whether the page should be “multi-split” into more than two pages, the total number of new pages to be added, and the range of indexed values assigned to each new page. These determinations are made as functions of the frequency with which the index page, and other index pages for the same index, have been split in the past, of the data distribution of values indexed by the leaf page, and of the degree of sequentiality of entries added to the leaf page. Leaf pages approaching capacity may also be scheduled for “pre-split” splitting during a period of lower utilization. These multi-split and pre-split operations reduce the numbers of index splits and of corresponding synchronous database-log writes.
