A method for redirecting Internet Protocol (IP) packets from a packet redirect source to a packet redirect destination through a switch fabric of Ethernet switches is disclosed. At the packet redirect source, the topological location and the identifier of the packet redirect destination are put in a first set of bits and a second set of bits of the destination Media Access Control (MAC) address field of the packet to be redirected. The switch fabric forwards the packet to the switch directly connected to the packet redirect destination according to the first set of bits. Then the switch forwards the packet to the packet redirect destination according to the second set of bits.

Redirection IP packet through switch fabric

A system and methods of using commodity switches to produce a switch fabric are disclosed. The system comprises switches organized in tiers. Each switch is connected to switches in higher tiers via its uplink switch ports and to switches in lower tiers via its downlink switch ports. A packet received from any downlink switch port is forwarded to one of the at least one link aggregation of uplink switch ports. A packet received from any uplink switch port is forwarded according to the first label in the packet. Each switch in the highest tier is configured to insert one or more labels in a packet to be sent out via the switches. A value in a label indicates the switch port to be selected to send out the packet received at a switch.

A system and methods of using commodity switches and commodity servers to produce a load-balanced, highly-available network for a computing cloud are disclosed. The system comprises switches and servers. The switches are organized in tiers. The switches in the highest tier are connected to the servers via uplink switch ports. The switches in the lowest tier are connected to devices external to the system via downlink switch ports. A packet received from any downlink switch port is forwarded to one of the at least one link aggregation of uplink switch ports. A packet received from any uplink switch port is forwarded according to the first label in the packet. A server is configured to insert one or more labels in a packet to be sent out via the switches. A value in a label indicates the switch port to be selected to send out the packet received at a switch.

An integrated virtual desktop and security management system provides the virtual desktop server functionality and, more importantly, security management for computing devices and servers in the corporate data network. The computing devices include computers running virtual desktop client software and computers running a complete operating system and applications. The system in this invention can intercept data packets exchanged among the computing devices and servers and also can scrutinize virtual machine computing and networking activities, and therefore, possess the capability of analyzing, logging, reporting, and permitting or denying computing and networking activities of devices in the corporate data network.

A method for creating low-cost interactive entertainment robots is disclosed. The cost of the robots is reduced by using a commodity computing device: smart phone, and by having robotic bodies use a decoder of a set of movement commands that facilitates the interoperability between a variety of smart phones and a variety of robotic bodies. Smart phones are equipped with powerful CPU, touch screen, USB, camera, microphone, Bluetooth, WI-FI, etc. They are fit for being the robot control units with the relevant robot applications installed. The cost of robotic bodies can be reduced by minimizing the amount of processing and sensing there and having them focus on mechanical movements. Furthermore, by defining and using a set of movement commands that promotes interoperability between a variety of robot control units and a variety of robotic bodies, the cost of robotic bodies can be reduced through mass production.

A method for building scalable Ethernet switch network and huge Ethernet switch is provided. The switch network is composed of a plurality of tiers of Ethernet switches forming a fat-tree topology. The bottommost tier connects to the end-stations. All switches except those in the top tier are typical IEEE802.1Q switches configured purposefully such that all packets from the end-stations are forwarded upstream to the top tier and are tagged with ingress port information. The top-tier switches possess a novel learning and forwarding capability such that a received packet is forwarded downstream to the destination end-station through one of a plurality of possible paths selected by a load balancing algorithm. The method can also be applied to build an Ethernet switch of a large number of ports.

A method for dynamic load balancing of packet flows on link aggregation provides dynamic assignment of individual packet flow to egress port that is least congested. The degree of congestion is measured by the utilization of the transmit queues. The dynamic assignments are maintained in a flow table. They are timed out by tracking packet tags in the transmit queues of corresponding scheduling priorities. The load balancing method is aware of quality of service requirements of the traffic and also capable of preserving packet order.
