    摘要: Network traffic is monitored and an optimal framing heuristic is automatically determined and applied. Framing heuristics specify different rules for framing network traffic. While a framing heuristic is applied to the network traffic, alternative framing heuristics are speculatively evaluated for the network traffic. The results of these evaluations are used to rank the framing heuristics. The framing heuristic with the best rank is selected for framing subsequent network traffic. Each client/server traffic flow may have a separate framing heuristic. The framing heuristics may be deterministic based on byte count and/or time or based on traffic characteristics that indicate a plausible point for framing to occur. The choice of available framing heuristics may be determined partly by manual configuration, which specifies which framing heuristics are available, and partly by automatic processes, which determine the best framing heuristic to apply to the current network traffic from the set of available framing heuristics.

    摘要: Ethernet Alarm Indication Signal (ETH-AIS) information for multiple Virtual Local Area Networks (VLANs) is consolidated and distributed to the multiple VLANs in a single Ethernet frame. Note, as used herein, “Alarm Indication Signal (ETH-AIS)” refers to an IEEE 802.x or ITU-T Y.1731 Ethernet Alarm Indication Signal. A device receiving the Ethernet frame with the consolidated ETH-AIS information typically forwards the frame out each port that communicates traffic for one of the VLANs included in the consolidated ETH-AIS information.

    摘要: Virtual storage arrays consolidate data storage from branch locations at data centers. The virtual storage array appears to storage clients as a local data storage; however, the virtual storage array data is actually stored at a data center. To overcome the bandwidth and latency limitations of wide area networks between branch locations and the data center, systems and methods predict, prefetch, and cache at the branch location storage blocks that are likely to be requested in the future by storage clients. When this prediction is successful, storage block requests are fulfilled from branch locations' storage block caches. Predictions may leverage an understanding of the semantics and structure of the high-level data structures associated with the storage blocks. Prefetching agents on storage clients monitor storage requests to determine the associations between requested storage blocks and the corresponding high-level data structures as well as other attributes useful for prediction.

    摘要: In a method for recovery of a clock from a received digital data stream and an apparatus for recovering a clock from a received digital data stream, phase-shifted clock signals are generated from a receiver's clock. After selecting one of the phase-shifted clock signals, two other phase-shifted clock signals are determined. Depending on sample values taken at rising/falling edges of the three selected phase-shifted clock signals, counter values are increased and compared. The selection of phase-shifted clock signals and the steps of sampling the input digital data stream, comparing the values and increasing counter values, if required, are repeatedly performed until the comparison result of the counter values indicates that one of the latter determined phase-shifted clock signals strobes the received digital data stream in the center of a bit period.
