  • Patent number: 9183076
    Abstract: Systems and methods for using carry-less multiplication (CLMUL) to implement erasure code are provided. An embodiment method of using CLMUL to implement erasure code includes initiating, with a processor, a first CLMUL call to calculate a first product of a data bit word and a constant, partitioning, with the processor, the first product into a high portion and a low portion, and initiating, with the processor, a second CLMUL call to calculate a second product of the high portion and a hexadecimal number portion, a bit size of the second product less than a bit size of the first product. The second product, or a third product generated by a third CLMUL call, is used to calculate a parity bit. Because the second product or the third product has a number of bits equivalent to the number of bits used by the processor, the erasure codes are more efficiently implemented.

  • Patent number: 9184884
    Abstract: Embodiments are provided for a cloud-based reliable media ingestion and transcoding. The embodiments comprise an improved backup mechanism where each worker node, such as a virtual machine, physical machine, workstation, or server, in a cloud or Internet environment handles one streamed media/video channel transcoding and another streamed media/video channel ingestion backup. To reduce ingestion storage demands, the ingestion backup storage is based on a pre-determined relatively short-term sliding window. When an ingestion and transcoding worker node fails, a new worker node is brought up to take over from the failed worker node the live transcoding task of a first channel and the ingestion backup task of a second channel. Additionally, the new worker node retrieves backup data for the first channel from a third worker node and a central media storage to ensure seamlessly uninterrupted live ingestion and transcoding of the first channel, and continues the ingestion backup task of the second channel.

  • Publication number: 20150319268
    Abstract: Hierarchical compression includes the contemporaneous implementation of link-layer and higher-layer compression on data flowing over a link. Hierarchical compression can be achieved by configuring network nodes positioned at the link-layer to recognize higher-layer compression symbols embedded in incoming data streams, and to adapt link-layer compression to compensate for those higher-layer compression symbols. One technique for adapting link-layer compression is to perform data chunking in-between higher-layer compression symbols. This may reduce the likelihood that higher-layer compression symbols will interfere with the network nodes ability to identify redundant data chunks at the link-layer. Another technique for adapting link-layer compression is to define the HASH algorithm in such a way that the hash of a data string renders the same hash value as the hash of the higher layer compression symbol corresponding to the data string.
