摘要： In one embodiment, an apparatus comprises a range selection module, a first stage of bloom filters, a second stage of bloom filters and a hashing module. The range selection module is configured to define a set of hash key vectors based on a set of range values associated with at least a portion of an address value from a data packet received at a multi-stage switch. The first stage of bloom filters and the second stage of bloom filters are collectively configured to determine that at least a portion of a hash key vector from the set of hash key vectors has a probability of being included in a hash table. The hashing module is configured to produce a hash value based on the hash key vector such that a first policy vector is selected based on the hash value and the first policy vector is decompressed to produce a second policy vector associated with the data packet.

摘要： One embodiment of the present invention provides a system that facilitates diagnostic logging for software components. During operation, the system receives program code for a software component that was generated from an object model, where a key attribute has been specified for the object model. During execution of the program code, the system detects when an instance of the key attribute for the object model is accessed, and attaches state associated with the instance to a thread context in the runtime environment. The system then appends this state to a log during a logging operation to facilitate discovering and analyzing program faults.

摘要： An example network device includes a control plane and a filter lookup module that includes a Bloom filter that supports parallel lookup of a maximum number of different prefix lengths. The filter lookup module accesses the Bloom filter to determine a longest length prefix that matches an entry in a set of prefixes. The control plane receives prefix lengths that include more than the maximum number of different prefix lengths supported by the Bloom filter, wherein the set of prefix lengths is associated with one application, generates, based on the received set of prefix lengths, two or more groups of different prefix lengths, wherein each of the two or more groups of different prefix lengths includes no more than the maximum number of different prefix lengths, and programs the filter lookup module with the two or more groups of different prefix lengths associated with the one application.
