Abstract: Scalable session management is achieved by generating a cookie that includes an encrypted session key and encrypted cookie data. The cookie data is encrypted using the session key. The session key is then signed and encrypted using one or more public/private key pairs. The encrypted session key can be decrypted and verified using the same private/public key pair(s). Once verified, the decrypted session key can then be used to decrypt and verify the encrypted cookie data. A first server having the private/public key pair(s) may generate the cookie using a randomly generated session key. A second server having the same private/public key pair(s) may decrypt and verify the cookie even if the session key is not initially installed on the second server. A session key cache may be used to provide session key lookup to save public/private key operations on the servers.

Abstract: A system and method for accelerating web page delivery is disclosed in one embodiment. Web requests are made to an edge server of a first point of presence (POP) of a content delivery network (CDN). The web content can be cached at the edge server in the first POP. Where the cache is missing the web content, it is queried from a second POP determined to be closer to the origin server for the web content. The second POP can have its own cache or request the web content from the origin server. Only missing components from the web content are passed to the first POP. Additionally, the missing components can be compressed.

Abstract: The technique introduced here involves using a block address and a corresponding generation number as a “fingerprint” to uniquely identify a sequence of data within a given storage domain. Each block address has an associated generation number which indicates the number of times that data at that block address has been modified. This technique can be employed, for example, to determine whether a given storage server already has the data, and to avoid sending the data to that storage server over a network if it already has the data. It can also be employed to maintain cache coherency among multiple storage nodes.

Abstract: One or more content delivery networks (CDNs) that deliver content objects for others is disclosed. Content is propagated to edge servers through hosting and/or caching. End user computers are directed to an edge server for delivery of a requested content object by a universal resource indicator (URI). When a particular edge server does not have a copy of the content object from the URI, information is passed to another server, the ancestor or parent server to find the content object. There can be different parents servers designated for different URIs. The parent server looks for the content object and if not found, will go to another server, the grandparent server, and so on up a hierarchy within the group. Eventually, the topmost server in the hierarchy goes to the origin server to find the content object. The origin server may be hosted in the CDN or at a content provider across the Internet.

Abstract: A data processing system enables global shared memory (GSM) operations across multiple nodes with a distributed EA-to-RA mapping of physical memory. Each node has a host fabric interface (HFI), which includes HFI windows that are assigned to at most one locally-executing task of a parallel job. The tasks perform parallel job execution, but map only a portion of the effective addresses (EAs) of the global address space to the local, real memory of the task's respective node. The HFI window tags all outgoing GSM operations (of the local task) with the job ID, and embeds the target node and HFI window IDs of the node at which the EA is memory mapped. The HFI window also enables processing of received GSM operations with valid EAs that are homed to the local real memory of the receiving node, while preventing processing of other received operations without a valid EA-to-RA local mapping.
