A two-tier Anycast addressing hierarchy enables deterministic traffic management in an Anycast system. Different locations of the Anycast system advertise a common Anycast cover route comprising a first-tier Anycast address with a first address prefix, and different specific routes comprising a set of second-tier Anycast addresses with a second address prefix, wherein each address of the set of second-tier Anycast addresses falls within the already advertised Anycast cover route, and wherein the second prefix is larger than the first prefix. Domain Name System (DNS) operation can resolve queries to the cover route when normal Anycast operation is desired or can be modified to resolve a subset of queries to a particular second-tier address in order to shift a deterministic amount of traffic based on the resolved subset of queries to a deterministically selected Anycast system location based on the location from which the particular second-tier address is advertised.

Some embodiments set forth systems and methods enabling a first network to use the resources of various second networks in order to localize delivery of the first network content from the various second networks in a secure manner. Some embodiments provide a token-based authentication scheme to ensure that any configured content access restrictions are effectuated at the first network and any of the second networks providing localized content delivery for the first network. The scheme involves a two phase user authentication, wherein the user is separately authenticated at the first network and the redirected to second network using either the same or different set of access restrictions. The first network exchanges a first encryption key with content providers for encrypting/decrypting the first access restriction and a second encryption key with a second network for encrypting/decrypting the second access restriction.
