Patent number: 7433303Abstract: In a network apparatus, control logic is provided to preemptively issue pause controls to a sender of network traffic of a link to preemptively regulate a rate the sender may send network traffic of the link. In one embodiment, the pause controls are sent periodically, with each including a pause duration. In one embodiment, at least a selected one of the pause duration and the periodicity of preemptive issuance is determined based at least in part on at least a selected one of a working capacity of storage medium allocated to service the link, a network traffic drain rate of the link, and a fill rate of the input line over which the network traffic of the link is received. In one embodiment, the networking apparatus is an optical networking module with the control logic disposed in a multi-protocol networking processor of the module.Type: GrantFiled: August 2, 2002Date of Patent: October 7, 2008Assignee: Null Networks LLCInventors: Alfred C.

Patent number: 7184408Abstract: Methods and apparatus provide single or multi-port, flexible, cost-effective, built-in self-test capabilities for network communications equipment, such as for example switches, and programmably generate, and subsequently analyze, one or more sequences of test packets, wherein the test packets simulate at least two flows of traffic. Such test packets can have programmable headers, payloads, and duty cycle. A line card embodying the present invention may generate its own traffic pattern, which may be similar or identical, to traffic patterns observed on Internet backbones. These traffic patterns may contain a bimodal distribution of control packets interspersed with data packets wherein the control packets and data packets are relatively short and long respectively. A plurality of test packet generators/receivers can be deployed in a network communications device having a plurality of ports. In such a configuration, test generator/receiver is associated with each of the plurality of ports.Type: GrantFiled: July 31, 2001Date of Patent: February 27, 2007Inventors: I.
