    Abstract: Methods, apparatus, and products for routing frames in a network using bridge identifiers, wherein the network includes a plurality of bridge nodes. At least one of the bridge nodes operates as an ingress bridge node through which frames are received into the network. At least one of the bridge nodes operates as an egress bridge node through which frames are transmitted out of the network. One of the bridge nodes receives, from the ingress bridge node, a frame for transmission to a destination node. The destination node connects to the network through the egress bridge node. The frame includes an ingress bridge identifier and an egress bridge identifier. The bridge that received the frame then routes the frame to the egress bridge node through which the destination node connects to the network in dependence upon the ingress bridge identifier and the egress bridge identifier included in the frame.

    Abstract: Described are embodiments directed at providing resilient services using architectures that have a number of failover features including the ability to handle failover of an entire data center. Embodiments include a first server pool at a first data center that provides client communication services. The first server pool is backed up by a second server pool that is located in a different data center. Additionally, the first server pool serves as a backup for the second server pool. The two server pools thus engage in replication of user information that allows each of them to serve as a backup for the other. In the event that one of the data centers fails, requests are rerouted to the backup server pool.

    Abstract: Methods, apparatus, and products for routing frames in a shortest path computer network for a multi-homed legacy bridge, wherein the network includes a plurality of bridges. At least two of the plurality of bridges operate as edge bridges through which the frames ingress and egress the network. A first edge bridge identifies a legacy bridge nickname for a legacy bridge connected to the network through the first edge bridge and a second edge bridge using active-active link aggregation. The first bridge receives a frame from the legacy bridge and determines, in dependence upon the frame's destination node address, an egress bridge nickname for a third bridge through which a destination node connects to the network. The first bridge then adds the legacy bridge nickname and the egress bridge nickname to the frame and routes the frame to the third bridge in dependence upon the egress bridge nickname.

    Abstract: Disclosed herein is a non-clog shredder that is used to shred solid matter entrained in a non-homogenous liquid-solid feed. In one embodiment of the invention, the shredder is located at the bottom of a toilet bowl and is used to shred solid disposable products such as napkins and diapers that are discarded in the toilet bowl. The shredder comprises a generally cylindrical cup that is open at one end, with a circular end-cap at the other end. The end-cap has an axial opening that allows the feed to pass through the cup. In one embodiment of the invention, the opening has recesses and/or teeth on the periphery of the opening. An impeller disposed against the circular end plate creates suction for transfer of the waste through the shredder. A cutting blade on the impeller assembly projects axially through the opening in the end-cap.

    Abstract: Distributing packets from an input link to multiple output links involves categorizing each incoming packet, selecting a mapping algorithm based on the packet category, and using the selected mapping algorithm for each packet to determine an output link for the respective packet. If packets are from a category that requires the order of the packets to be maintained, then the selected mapping algorithm causes packets from the same set of packets to be distributed to the same output link. If packets are from a category that does not require the order of the packets to be maintained, then the selected mapping algorithm can cause packets to be distributed more evenly among the multiple output links. Hashing can be used to distribute in-order packets from the same set to the same output link. Load balancing and round-robin distribution can be used to distribute out-of-order packets more evenly across the output links.

    Abstract: Air quality control system scrubs flue gas of SO.sub.2 and particulates with a slurry of lime/limestone and water. The contact between the slurry is in a centrifugal section which is the upper part of a tank in which the chemical action is completed and from which the slurry is recirculated to the contact section. The gas to be scrubbed is inserted into a circular path within the scrubbing section into which the slurry is sprayed. The treated gas is withdrawn from the circular path in heat exchange relationship with the incoming gas.
