Abstract: Techniques are provided for handling failures of DNS (domain name system) servers to respond to DNS queries. A DNS resolver is configured to resolve domain names, and includes a time-to-live (TTL)-based cache, a negative cache, and a long term store cache. The TTL-based cache is configured to temporarily store domain names with resolved IP addresses. The negative cache is configured to store negative entries that include information indicating domain names that were failed to be resolved. The long term store cache is configured to store domain names with resolved IP address for an indefinite time period. The caches are accessed in a manner that enables fewer DNS query retries to be performed when a DNS server is non-responsive, to reduce delays and network traffic. Furthermore, the DNS resolver may reduce a number of DNS queries performed the longer the DNS server stays non-responsive.

Abstract: Various exemplary embodiments relate to a method and related network node and machine-readable storage medium including a policy and charging rules node (PCRN) receiving a plurality of related service requests from different devices. The PCRN may proceed to generate a policy and charging control (PCC) rule based on at least one service request and other information stored in the PCRN if a mate service request does not arrive during the duration of a waiting timer. If the mate service request arrives subsequent to the expiry of the waiting timer, the PCRN may then generate a subsequent PCC rule to replace the previously generated rule, with the new PCC rule incorporating information from both of the mate service requests.

Abstract: The invention disclosed herein enables a collection of computers and associated communications infrastructure to offer a new communications process which allows information providers to broadcast information to a population of information consumers. The information may be targeted to those consumers who have a precisely formulated need for the information. Information can be brought to the attention of the consumer precisely when it has become applicable, which may occur immediately upon receipt of the message, but may also occur long after the message arrives. The communications process may operate without intruding on consumers who do not exhibit the precisely-specified need for the information, and it may operate without compromising the security or privacy of the consumers who participate. The communications process may be used to facilitate particular client and server queries and responses, such as for example, in a travel agency environment.
