    Abstract: Systems and methods are described to enable management of redundant route announcements in an access point including multiple packet processors. Route controllers are described that can generate routing information distributing incoming packets to the access point among the packet processors. The route controllers can operate redundantly, such that a failure of a single controller does not cause a complete failure of the access point. To avoid different announcements by different route controllers (particularly under partial failure scenarios), the route controllers utilize a strongly consistent data store to store routing information. So long as a record within the data store contains valid information, it is considered authoritative and routing information from the record is announced by all route controllers. If the information is invalid, the route controllers attempt to overwrite the information with new, higher priority routing information. A single write succeeds, resulting in new authoritative routing information.

    Abstract: Systems and methods are described to enable a DNS service to encode information into a network address to be advertised by the DNS service. Information encoded by a DNS service may include, for example, an identifier of a content set to which the network address corresponds (e.g., a domain name) and validity information, such as a digital signature, that verifies the validity of the network address. On receiving a request to communicate with the network address, a destination device associated with the network address may decode the encoded information within the network address to assist in processing the request. In some instances, the encoded information may be used to identify malicious network transmissions, such as transmissions forming part of a network attack, potentially without reliance on other data, such as separate mappings or contents of the data transmission.

    Abstract: Systems and methods for sloppy routing are provided. A client transmits a DNS query corresponding to a requested resource to a content delivery network (CDN) service provider. In some embodiments, the CDN service provider processes the DNS query to determine whether a threshold content delivery bandwidth has been exceeded by data links at cache servers. In other embodiments, additionally or alternatively, the CDN service provider determines whether a content provider has exceeded a threshold network usage that indicates a price at which the CDN service provider to provide content on behalf of the content provider. Using both or either of these thresholds, the CDN service provider can further process the DNS query by providing an alternative resource identifier or a cache IP address, both associated with an alternative POP. In some embodiments, the CDN service provider determines a routing mode for the response to the DNS query.
