  • Patent number: 8611215
    Abstract: The present invention provides systems and methods for adaptive digital data transmission rate control. A digital data transmission system for adaptively transferring packets over a transmission link includes a client device having a bandwidth control module and a host device coupled to the client device over the transmission link. The host device includes one or more bandwidth control registers and a packet builder. The bandwidth control module determines a packet speed and/or size for packets transmitted from the host device to the client device over the transmission link. The bandwidth control registers store the requested packet size and/or rate. The packet builder accesses these registers when transmitting packets to determine the requested packet size and/or rate.

  • Patent number: 8599881
    Abstract: A system and method for redundant synchronizing to a reference clock for data communications. A determination is made whether a first data stream and a second data stream are available. The first data stream and the second data stream are received through opposing directions of a communications ring. A first data packet and second data packet are received at a remote node in response to the first data stream and second data stream being available. A timing characteristic of the first data packet and the second data packet correspond to a tick of a reference clock. The tick of the reference clock is extracted utilizing a timing characteristic of the first data packet or second data packet in response to the first data stream or the second data stream being available. A secondary clock is disciplined with the reference clock by adjusting the secondary clock based on a difference between times measured by the reference clock and the secondary clock to generate a clock signal.

  • Patent number: 8565231
    Abstract: The present invention provides methods and devices for implementing a Low Latency Ethernet (“LLE”) solution, also referred to herein as a Data Center Ethernet (“DCE”) solution, which simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet and storage traffic. Some aspects of the invention involve transforming FC frames into a format suitable for transport on an Ethernet. Some preferred implementations of the invention implement multiple virtual lanes (“VLs”) in a single physical connection of a data center or similar network. Some VLs are “drop” VLs, with Ethernet-like behavior, and others are “no-drop” lanes with FC-like behavior. Some preferred implementations of the invention provide guaranteed bandwidth based on credits and VL. Active buffer management allows for both high reliability and low latency while using small frame buffers. Preferably, the rules for active buffer management are different for drop and no drop VLs.
