Method and system for adaptive queue and buffer control based on monitoring in a packet network switch

United States 8,665,892
Issued March 4, 2014

Certain aspects of a method and system for adaptive queue and buffer control based on monitoring in a packet network switch are disclosed. Aspects of one method may include pre-allocating packet buffers from a pool of packet buffers in a network switching device based on anticipation of a type of application data being handled by a particular port of the network switching device according to packet classification and tracking. The buffers may be dynamically allocated and deallocated from the pool of packet buffers for a particular port of the network switching device based on changes to the application data.

Method and system to provide blade server load balancing using spare link bandwidth(Link)

United States 7,835,363
Issued November 16, 2010

A blade server with an improved method and apparatus for controlling the capacity utilization of the servers is disclosed. Capacity utilization information is obtained from blade servers mounted on a common backplane. The servers provide information concerning capacity utilization using spare link bandwidth without polling or the use of special messages. The blade manager then allocates network traffic based on a utilization algorithm in order to balance the capacity of the server in an efficient manner.

Method and system to provide blade server load balancing using spare link bandwidth(Link)

United States 8,102,874
Issued January 24, 2012

A method for processing network information in a multi-server platform is disclosed and includes receiving by a blade server manager, capacity utilization information embedded in spare link bandwidth from a plurality of blade servers operably coupled to the blade server manager. Digital information received on a digital communication link may be forwarded to one of the plurality of blade servers. The blade servers may be selected based on the received capacity utilization information. The capacity utilization information may include blade server work load capacity, blade server power saving capacity, blade server CPU percent utilization, and/or data representing blade server interrupt utilization. The blade server manager may be operably coupled to an Ethernet network and/or an external network.

Method and system for exploiting spare link bandwidth in a multilane communication channel(Link)

United States 7,804,855
Issued September 28, 2010

A system for encoding data in a multilane communication channel may include at least one processor operable to generate, from existing control characters in a character set, expanded control characters utilized for controlling the data in each lane of the multilane communication channel. Each lane of the multilane communication channel may transport the data in a similar direction. The at least one processor is also operable to control at least one of the lanes of the multilane communication channel using at least one of the generated control characters. If a first control character of the existing control characters is a start-of-packet control character, the at least one processor is then operable to select a second control character from any other of the generated expanded control characters, and to indicate a start of a packet using the selected second control character for at least one of the lanes.

Method and system for exploiting spare link bandwidth in a multilane communication channel(Link)

United States 7,463,651
Issued December 9, 2008

Aspects of the invention may include a method for encoding data in a multilane communication channel. The method may include generating from existing control characters in a character set, an expanded control character which may be utilized for controlling data in each lane of the multilane communication channel. The expanded control character may utilize spare link bandwidth. At least one of the lanes may be controlled using at least one of the generated existing control characters. If a first control character is an alignment character, a second control character may be selected from any other existing control characters. The first control character may be combined with the second control character to generate a third control character. Each of the combinations of the first and second control characters may represent an expanded control character. The existing control characters may be a configuration character, an idle character or an encapsulation character.

Method to overlay a secondary communication channel onto an encoded primary communication channel(Link)

United States 6,930,621
Issued August 16, 2005

Disclosed herein is a method and system for providing a secondary communication channel overlaid on a primary communication channel using an enhanced encoding method to effectively expand the utilized information capacity of the primary communication channel. Aspects of the invention may include encoding a portion of at least a first word of one or more data packets in a datastream. A running disparity of the encoded word may be reversed. Hence, if an encoded running disparity of an encoded word is RD positive, i.e., RD(+), then the running disparity is reversed to RD negative, i.e., RD(-). Similarly, if an encoded running disparity is RD negative, i.e., RD(-), then the running disparity is reversed to RD positive, i.e., RD(+). The word may be a data word, control word, or an idle word corresponding to a data packet, a control packet, and an idle packet, respectively.
