    摘要: Frame contained destination information may be used by a switch to identify an appropriate output port for a given frame without performing a table access operation. This reduces the processing requirements of the switch to enable the switch to handle frames more efficiently. The frame contained destination information may be contained in the frame's local destination MAC addresses (DA) such that a portion of the DA directly indicates, for each switch that handles the frame, an output port for that switch. Different portions of the DA may be used by different switches, depending on where they are in the network hierarchy. Large switches may also use sub-fields within their allocated portion in the DA to identify internal switching components. A location resolution server may be provided to store and distribute IP and MAC addresses and respond to local ARP requests on the local domain.

    摘要: Device-wide performance guarantees may be implemented in a network element using a pull forwarding scheme by using separate proceses on the network element communicating via handshake signals to enable coordination between the aspects of the network element. One class of processes execute at the ingress queues, a second class of process execut at junction points, and a final class of processes execute at the egress ports. The combination of these separate processes leads to the correct scheduling of frames in a device-wide manner as if there were a centralized scheduler with complete information about all queued frames. As a result, the performance guarantees of the intended scheduling algorithm are preserved and are provided in a device-wide manner. The scheduling algorithms that are supported include round-robin, deficit round robin, negative deficit round robin, weighted round robin, and strict priority.

    摘要: A computer implemented method, system, and computer usable program code for simplifying compiler-generated software code by creating a stub routine for checking storage contiguity. A stub routine is generated for a subroutine. The stub routine is used to determine whether data is contiguous for the subroutine. A subroutine call in the code is replaced with a stub routine call for the stub routine. The subroutine call has at least one argument. The stub routine call includes each argument for the subroutine call. The code is executed. The stub routine is called by the stub routine call to determine whether data is contiguous for the subroutine.
