Abstract:
A system and method are provided for deduplication (dedup) of data file information in a network of distributed data filers. A host, including a metadata service (MDS) and a data node (DN), receives a block count and hash group calculations for a file from a network-connected client device. The MDS creates a file map with target addresses, and compares the calculated hash group to hash groups associated with stored blocks of data in a global dedup hash table. If a match is found, the MDS directs the client device not to send the block of data associated with matching hash group, and reallocates the address of the block of data from the target address.
Abstract:
A device and method are provided for guaranteeing a quality of service (QoS) for a network-connected device in a distributed service platform (DSP) or cloud computing system. The method establishes a first set of attributes or performance criteria for a selected platform component. The selected platform component may be a system component for processing data or a network component for connecting system components. For example, the first set of attributes may be supplied by a client in an SLA. A second set of attributes is derived for the unselected platform component necessary to support the first set of attributes. For example, if a first set of attributes is established for a system component, then a second set of attributes would be derived or calculated for a network component. As a result, a DSP QoS is supplied to a network-connected (e.g., client) device, guaranteeing the first set of attributes.
Abstract:
A method and system are provided for accelerated data uploading to a remote service device destination. An on-line (third party) storage device receives an upload request message from a network-connected client device. A unique first descriptor in a descriptor field of the upload request message is accessed and compared to a list of descriptors maintained by the on-line storage device. If the accessed first descriptor is on the list, a first file is read that is stored in the on-line storage device and associated with the accessed first descriptor. The first file is then sent to a network-connected remote service device.
Abstract:
A system and method are provided for downloading data to a client device by deferral to an on-line storage device. A client sends a login request to a network-connected remote service device, and receives a remote service identification (ID) from the remote service device. The client sends a token request message, with the remote service ID, to a network-connected on-line storage device, and receives a first token identification (ID) associated with a first session and an on-line storage ID from the on-line storage device. The client sends an upload request message to the remote service device. The upload request message includes the first token ID and on-line storage ID, and identifies a first file to be uploaded to the on-line storage device. Subsequent to the on-line storage device receiving the first file from the remote service device, the client downloads the first file from the on-line storage device.
Abstract:
A system and method are provided for calculating passive host proximity in an environment of network-connected hosts. At least three controller hosts send inquiries to target hosts in the environment, including at least two passive (non-controller) hosts. A time interval is recorded between each inquiry and an associated response, and the recorded time intervals are converted into logical distance measurements between the controller host and each target host. The logical distance measurements are then used to calculate a logical distance between the two passive hosts. A logical triangle is constructed between a first controller host (H1) and the two passive hosts (S1, S2) using a first logical distance side (H1S1) having a known value, a second logical distance side (H1S2) having a known value, and a third logical distance side (S1S2) having an unknown value. Trigonometric relationships solve for the unknown value of the third logical distance side.
