摘要:
In system of networks that are not fully meshed with each other and that are capable of processing distributed hash table (DHT) Put and Get messages, message flooding of GET messages is limited by maintaining a list of DHTs the GET has visited. Also, PUT messages include not only the storage location key in the home network but also a list of networks that the PUT has visited, in essence establishing a dynamically changing path within the PUT back to the home network.
摘要:
In a tiered system of networks capable of processing distributed hash table (DHT) Put and Get messages, if a sending network of a Put or Get is at a tier below a subject tier at which a subject network receiving the message is located, the message is forwarded to networks at tiers below the subject tier. On the other hand, if the sending network is at a tier equal to or above the subject tier, the message is forwarded to all networks in the system other than the sending network.

A node in an overlay network requests a ranked list of other nodes in multiple areas of the overlay network that can provide a desired piece of content or service to the requesting node. A separate node such as a router generates the ranked list using a routing algorithm, returning the list to the requesting node so that the requesting node may acquire the desired content or service from the nearest node in the overlay network.

Systems may use explicit ratings from users to construct user to user correlations. This technique may reduce the user-content correlation to a single dimension, i.e., the content that a plurality of users may rate similarly. Embodiments of the present invention may use DHT as an underlying distributed signaling mechanism, but may also make the rating implicit. Furthermore, embodiments of the present invention may construct the user to content correlation based on multi-dimensional metadata related to the content.
摘要:
In system of DHT rings that are not filly meshed with each other, flooding of PUT and GET messages is limited by PUTting a content key indicating an actual storage location of content from a content provider only to root DHTs associated with the content provider, and PUTting a secondary key indicating a subset of DHT rings at which content from the content provider might be stored only to DHT rings for which the content provider desires the content to be available. When a DHT receives a GET it first determines from the content key whether it can provide the content and if not, the DHT obtains the subset of DHT rings from the secondary key and forwards the GET of the content key to the corresponding root DHTs.
