System And Method For Controlling Access To Content Carried In A Caching Architecture
US Patent:
7577754, Aug 18, 2009
Filed:
Apr 26, 2001
Appl. No.:
09/845088
Inventors:
Bradley R. Smith - Santa Cruz CA, US
Assignee:
Adara Networks, Inc. - San Jose CA
International Classification:
G06F 15/173
US Classification:
709238, 709227, 709245, 709246, 709239, 709242, 709228, 370390
Abstract:
A set of access control labels is assigned to each of a number of users of a caching infrastructure in a network. The labels are used in specifying access control lists for content of the users. Requests for the content are referred to selected information object repositories of the caching infrastructure without regard as to whether the content is actually stored at the information object repositories; and access to the content is controlled according to access lists developed according to the access control labels. Access to the content may be controlled by comparing information included in uniform resource locators (URLs) to the access control lists. Such information may be one or more digital signatures, for example, which identify one or more of: the source of the requests, and an owner of an information object being requested. The access control lists are preferably maintained corresponding to the access control labels, which may be hierarchical in nature. Each of the information object repositories of the caching infrastructure may store a copy of each of the access control lists.
System And Method For Using A Mapping Between Client Addresses And Addresses Of Caches To Support Content Delivery
US Patent:
7565450, Jul 21, 2009
Filed:
Apr 26, 2001
Appl. No.:
09/843789
Inventors:
Bradley R. Smith - Santa Cruz CA, US
Assignee:
Adara Networks Inc. - San Jose CA
International Classification:
G06F 15/16, G06F 15/173
US Classification:
709245, 709238, 709217, 709219
Abstract:
Various information object repository selection procedures for determining which of a number of information object repositories should service a request for the information object include a direct cache selection process, a redirect cache selection process, a remote DNS cache selection process, or a local DNS cache selection process. Different combinations of these procedures may also be used. For example different combination may be used depending on the type of content being requested. The direct cache selection process may be used for information objects that will be immediately loaded without user action, while any of the redirect cache selection process, the remote DNS cache selection process and/or the local DNS cache selection process may be used for information objects that will be loaded only after some user action.
System And Method For Using Network Layer Uniform Resource Locator Routing To Locate The Closest Server Carrying Specific Content
US Patent:
7908337, Mar 15, 2011
Filed:
Apr 26, 2001
Appl. No.:
09/844856
Inventors:
Bradley R. Smith - Santa Cruz CA, US
Assignee:
Adara Networks, Inc. - San Jose CA
International Classification:
G06F 15/16
US Classification:
709217, 709238, 709219, 709227, 709245, 709242
Abstract:
A request for an information object at an address identified by a uniform resource locator (URL) is received; and the URL is mapped to a corresponding anycast address for the information object. Thereafter, the anycast address for the information object may be resolved to a unicast address for the information object, and the information object sent to the client. The request may be received at an information object repository that is topologically closer to the client than any other information object repository. This closest information object repository may be selected according to specified performance metrics, such as: average delay from the selected information object repository to a source of the request, average processing delay at the selected information object repository, reliability of a path from the selected information object repository, available bandwidth in said path, and loads on the selected information object repository.
System And Method For Resolving Network Layer Anycast Addresses To Network Layer Unicast Addresses
US Patent:
7725596, May 25, 2010
Filed:
Apr 26, 2001
Appl. No.:
09/844759
Inventors:
Bradley R. Smith - Santa Cruz CA, US
Assignee:
Adara Networks, Inc. - San Jose CA
International Classification:
G06F 15/173
US Classification:
709238, 709203, 709227, 709228, 709229, 709245, 709240, 709242
Abstract:
An information object repository is configured to resolve a network layer anycast address to a network layer unicast address in response to a request for an information object at the network layer anycast address. The information object repository may be further configured to resolve the network layer anycast address by transmitting a request for the network layer unicast address and awaiting a response thereto, and, in some cases, to return a failure message to a source of the request for the information object if the response to the request for the network layer unicast address is not received within a timeout period. Preferably, the request for the network layer unicast address is a single IP packet that includes the network layer anycast address. Similarly, the request for the network layer unicast address is preferably a single IP packet that includes the network layer unicast address. The response to the request for the network layer unicast address may be returned by a host having the network layer unicast address, or another network node configured to do so.
System And Method For Using Uniform Resource Locators To Map Application Layer Content Names To Network Layer Anycast Addresses
US Patent:
7343422, Mar 11, 2008
Filed:
Apr 26, 2001
Appl. No.:
09/844857
Inventors:
Bradley R. Smith - Santa Cruz CA, US
Assignee:
Adara Networks, Inc. - San Jose CA

709238, 709227, 709245, 709246, 709239, 709242, 370390
Abstract:
A request for an information object at an address identified by a uniform resource locator (URL) is received; and the URL is mapped to a corresponding unicast address for the information object. Thereafter, the unicast address for the information object may be used as an anycast address.
System And Method For Information Object Routing In Computer Networks
US Patent:

Assignee:
Adara Networks, Inc. - San Jose CA
International Classification:
G06F 15/173
US Classification:
709238, 709242
Abstract:
An address of a server that should supply an information object or service to a requester is returned in response to a request therefor. The address of the server that is returned is an optimal server selected according to specified performance metrics. The specified performance metrics may include one or more of an average delay from the server to another, average processing delays at the server, reliability of a path from the server to another, available bandwidth in said path, and loads on the server.
