A distributed switchless system characterized by full mesh connectivity is disclosed. The full mesh distributed switchless system allows direct and indirect communication between a source node and a destination node. In direct communication, data propagates via links connecting the source and destination nodes. In indirect communication, data is first sent to an intermediate node via links connecting the source and intermediate nodes. The intermediate node sends the data to the destination node via links connecting the intermediate node and the destination node. The traffic can be divided into all available links across the nodes, rather than only the links connecting the source and destination nodes. Because indirect communication uses more links compared to direct communication, the traffic in each link is smaller. Consequently, the switchless distributed interconnect system can operate with fewer links between any two nodes and links with smaller bandwidth.

In one embodiment, for each port of the link aggregation group, the number of table entries of the port selection table is substantially proportional to the port speed of that port of the link aggregation group.
Methods for embedding an out-of-band signal into a communication protocol capture stream
One or more out-of-band input signals (GPIO) are handled and efficiently embedded into a USB capture stream. In order to conserve resources, the state of the input signals can be sent only when a change occurs.

Furthermore, because digital inputs may happen during a USB packet, the digital inputs are queued in a FIFO buffer until there is an opportunity to send the digital inputs. Even though the state of the inputs may be sent at a later time, the state of the inputs may be time-stamped when the state of the inputs is perceived by the analyzer.

Q-in-Q Ethernet rings
A resilient virtual Ethernet ring has nodes interconnected by working and protection paths. Each node has a set of VLAN IDs (VIDs) for tagging traffic entering the ring by identifying the ingress node and whether the traffic is on the working or protection path. MAC addresses are learned in one direction around the ring. A port aliasing module records in a forwarding table a port direction opposite to a learned port direction. Each node can also cross-connect working and protection paths. If a span fails, the two nodes immediately on either side of the failure are cross-connected to fold the ring. Working-path traffic is cross-connected onto the protection path at the first of the two nodes and is then cross-connected back onto the working path at the second of the two nodes so that traffic always ingresses and egresses the ring from the working path.

An assured message delivery system with resiliency receives messages from publishing client(s) and delivers them to subscribing clients. A primary system delivers the messages during normal operation. A secondary system mirroring the configuration of the primary system takes over responsibility for delivering the messages in the event of failure of the primary system. The secondary system is connected to the primary system over a communications link. The primary system sends copies of the messages to the secondary system over the communications link. The secondary system stores replicate messages and sends acknowledgement messages back to the primary system.
Read ahead caching of data from cloud storage and method thereof
A high tier storage area stores a stub file and a lower tier cloud storage area stores the file corresponding to the stub file. When a client apparatus requests segments of the file from the high tier storage area, reference is made to the stub file to determine a predicted non-sequential pattern of requests to the segments by the client apparatus. The high tier storage area follows the predicted non-sequential pattern of requests to retrieve the segments of the file from the cloud prior to the client apparatus actually requesting the segments. As such, the file may be efficiently provided to the client apparatus while also efficiently storing the file on the lower tier cloud storage area.
