Abstract: A switch may operate in a cut-through mode and a store-and-forward mode. While in a default cut-through mode, the switch continuously monitors ports for certain health metrics. If those health metrics fall below a threshold, the switch changes to operate in a store-and-forward mode, either for a predetermined period of time or until the health metrics rise above a threshold, at which point the switch can resume cut-through mode operations. If health metrics fall below an even lower threshold, or remain below threshold for a predefined period of time, the switch can automatically alert a remote system or software process.

Both the unlatching, movement, and latching are remotely controlled. Positional indicators, for example Global Positioning Systems or similar systems, are provided to monitor and assist in controlling PSB segment movement and unlatching, and movement of the PSB segments in a desired direction to a desired location.

Based on a stream partitioning policy, the control node determines an initial number of worker nodes to be used.

Abstract: Techniques for embedding fabric addressing information within Ethernet media access control (MAC) addresses is disclosed herein and allows a multi-node fabric having potentially millions of nodes to feature Ethernet encapsulation without the necessity of a lookup or map to translate MAC addresses to fabric-routable local identifiers (LIDs). In particular, a locally-administered MAC address may be encoded with fabric addressing information including a LID. Thus a node may exchange Ethernet packets using a multi-node fabric by encapsulating each Ethernet packet with a destination MAC address corresponding to an intended destination. As the destination MAC address may implicitly map to a LID of the multi-node fabric, the node may use an extracted LID value therefrom to address a fabric-routable packet. To this end, a node may introduce a fabric-routable packet encapsulating an Ethernet packet onto a multi-node fabric without necessarily performing a lookup to map a MAC address to a corresponding LID.

Abstract: The invention relates to a method for requesting uplink resources by a user equipment in a communication system, wherein a DRX, Discontinued Reception, function is running at the user equipment. The transmission of a scheduling request for requesting uplink resources to a radio base station is triggered upon triggering of a buffer status report in the user equipment. However, the triggering of the scheduling request is delayed such that the scheduling request is triggered in one of the subframes—preferably the first subframe—of an On-Duration period of a DRX cycle according to the DRX function. Correspondingly, the triggered scheduling request is transmitted to the radio base station in the next possible scheduling request transmission occasion after the triggering of the scheduling request is delayed.
