A method includes, with a first execution unit of a processor, executing instructions for a processing task on behalf of a first virtual container. The first virtual container is configured to utilize computing resources of the first execution unit without demanding more computing resources than the first execution unit provides. The first execution unit may have exclusive access to a first arithmetic logic unit (ALU). The method further includes, with a second execution unit of the processor, processing instructions for the processing task on behalf of a second virtual container. The second virtual container is configured to utilize computing resources of the first execution unit without demanding more computing resources than the first execution unit provides. The second execution unit may have exclusive access to a second Arithmetic Logic Unit (ALU). The first execution unit and the second execution unit operate in parallel.

A commuter groups service (CGS) allows commuters to join commuter groups so that they are able to socialize while commuting. Through the commuter groups, the users may share commuting routes, traffic updates, road conditions, and other information. Group members may arrange car pools, short term riding arrangements, and may anonymously or directly contact each other. The CGS may collect group member position information, e.g. GPS information, to enable the CGS to calculate traffic conditions and to select location specific information for group members. The system may include an on-line service accessible through a computer or wireless networking device. The user may log into the CGS, create or modify a user profile, and join groups of their choosing. Groups may be associated with specific events or with getting to/from work. Commuter groups may be formed for commuters that use private vehicles and/or public transportation.

Method and apparatus for enabling commuter groups

A control system enables transport of payload data across a dual counter rotating ring (DCRR) network having two or more nodes, each node providing access to the DCRR network by a respective local area network (LAN) subtending the node. The control system comprises a topology learning entity operative within each node for monitoring individual, links of the DCRR, discovering the active topology of the DCRR, communicating topology changes to other nodes in the DCRR, and informing frame forwarding and learning processes of the topology to enable failover to redundant resource upon detection of a network component failure. A frame forwarding process selects a shortest path route between a source and a destination node in the DCRR, and forwards frames to the destination node via the selected shortest path route. An address learning process inspects a source medium access control (MAC) address in each received frame to learn a shortest path route for each MAC address.

A method and apparatus for providing a Virtual Private Network (VPN) over a connectionless network connecting a plurality of Local Area Networks (LANs), such as an Ethernet network, is disclosed. The method and apparatus comprises associated each VPN with a unique identifier and each LAN of the VPN with a interface device connecting the LAN to the connectionless network, which may be for example, a Synchronous Optical Network (SONET). The interface device may service a plurality of LANs. Accordingly, each LAN is associated with a User-Network Interface that forms part of the interface device. Each data packet destined for a second LAN, such Ethernet frames, received by the interface device for a first LAN is encapsulated with, if known, a Media Access Control (MAC) address of the interface device connected to the second LAN, the VPN's unique identifier, and the port on the interface device connected to the second LAN. Additionally, the corresponding MAC and port address of the first interface device is also used to encapsulate the Ethernet frames. If the MAC and port address is not known (i.e., it is not stored in a database on the first interface device), the first interface device multicasts an encapsulated Ethernet packet to the entire VPN. The first interface device maintains (i.e., updates and appends) its database of MAC and port addresses in response to encapsulated data frames received by the first interface device.
