Apparatus And Methods For Scheduling And Performing Tasks

View page
US Patent:
6757897, Jun 29, 2004
Filed:
Feb 29, 2000
Appl. No.:
09/515198
Inventors:
Zhanhe Shi - San Jose CA
Qingming Ma - Santa Clara CA
Saravanan Agasaveeran - Sunnyvale CA
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
G06F 900
US Classification:
718102, 718100, 718104, 718103, 718107, 710240, 710243
Abstract:
The invention provides unique mechanisms and techniques for a computing device to perform various tasks in a multi-tasking or time sliced environment. A general task scheduling algorithm can select various time slices or priorities for task performance. However, in a dedicated device such as a data communications device, a primary task such as a data transfer task may be so heavily favored by the general task scheduling algorithm, such as in heavy network traffic conditions, that other tasks may be starved of processor time. As such, the system of the invention allows the primary task, to track a first time period Y, and upon expiration of this time period Y, to generate a yield signal to a yielding scheduler. The yielding scheduler can then disable performance of the primary task(s) and track a second time period X during which other tasks may be performed. At the expiration of the second time period X, the primary task(s) which were disabled upon the occurrence of the yield signal are then re-enabled for performance and the yielding scheduler selects a task for performance.

Packet Prioritization Processing Technique For Routing Traffic In A Packet-Switched Computer Network

US Patent:
6798743, Sep 28, 2004
Filed:
Mar 22, 1999
Appl. No.:
09/274091
Inventors:
Qingming Ma - Santa Clara CA
Saravanan Agasaveeran - Sunnyvale CA
Zhanhe Shi - San Jose CA
Steven Berl - Piedmont CA
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04J 116
US Classification:
370235, 370413
Abstract:
A two-phase packet processing technique is provided for routing traffic in a packet-switched, integrated services network which supports a plurality of different service classes. During Phase I, packets are retrieved from the router input interface and classified in order to identify the associated priority level of each packet and/or to determine whether a particular packet is delay-sensitive. If it is determined that a particular packet is delay-sensitive, the packet is immediately and fully processed. If, however, it is determined that the packet is not delay-sensitive, full processing of the packet is deferred and the packet is stored in an intermediate data structure. During Phase II, packets stored within the intermediate data structure are retrieved and fully processes. The technique of the present invention significantly reduces packet processing latency, particularly with respect to high priority or delay-sensitive packets. It is easily implemented in conventional routing systems, imposes little computational overhead, and consumes only a limited amount of memory resources within such systems.

Methods And Apparatus For Moving Data Elements Within A Data Communications Device

US Patent:
6832265, Dec 14, 2004
Filed:
Jan 7, 2000
Appl. No.:
09/479511
Inventors:
Qingming Ma - Santa Clara CA
Saravanan Agasaveeran - Sunnyvale CA
Satish Gannu - Bangalore, IN
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
G06F 1516
US Classification:
709250, 37039542
Abstract:
The invention is directed to techniques for moving data elements within a data communications device which prioritizes handling transmit interrupts over handling receive interrupts. Preferably, while attending to transmit interrupts, the device gives priority to the âhungriestâ interfaces. In one arrangement, the device includes multiple network interfaces which are capable of transmitting and receiving data elements with a network, and a controller, coupled to the interfaces. The controller is configured to perform a method comprising the steps of: assigning weights to the interfaces based on interface transmission capacities and/or the number of data elements ready for transmission through the interfaces; determining which of the interfaces indicates readiness to transmit a data element to the network and which of the interfaces indicates receipt of a data element from the network; exclusively running, for each interface indicating readiness to transmit a data element to the network, a transmit interrupt handler to load that interface with a data element for transmission if such a data element is available for transmission within the data communications device (the handling order of the interfaces being determined by the weights so that the âhungriestâ interfaces are handled first); and after the step of exclusively running transmit interrupt handlers, running, for at least one interface which indicates receipt of a data element from the network, a receive interrupt handler to process that data element and restricting the amount of time consumed running the receive interrupt handlers before handling transmit interrupts again. Since the device prioritizes handling transmit interrupts over receive interrupts in a weighted preferential manner, the device handles transmit interrupts as early as possible to move data elements quickly to the interfaces. Accordingly, it is less likely that interfaces will âstarveâ for data elements.
