Integrated mobility management mechanisms monitor a mobile host's degree of mobility and the applications it executes. Mobile hosts move between wireless-access, micro-mobility domains interconnected through a backbone network. While the mobile host is stationary, MIP-LR and SIP systems operate to ensure TCP and RTP / UDP packets, respectively, traveling to / from the mobile host are properly routed through the backbone to the host's current domain. An MMP system routes packets through this domain. As the host moves within a domain, the MMP system updates the domain routing to the mobile host's new location. As the mobile host moves between domains, the host obtains a new IP address and the MMP system establishes routing within the new domain to the mobile host's new location. In addition, the MIP-LR and SIP systems activate to ensure the TCP and RTP / UDP packets, respectively, are automatically re-routed through the backbone to the new domain.

A rack for mounting electronic equipment includes a pair of vertical support members having a regular pattern of mounting apertures that repeats linearly at a regular interval and a vertically-oriented cable guide, disposed generally adjacent one of the support members, having a plurality of outwardly-extending projections forming cable rings. The cable rings are disposed along the length of the cable guide at a second regular interval that is a whole number multiple of the first regular interval.

A multitenant deployment includes a computing cluster that executes multiple containerized instances of a software application. Each containerized instance is associated with one or more datastores that can be assigned to different tenants. A registry store maintains a mapping between tenants and datastores, thereby allowing a registry manager to properly route tenant requests to the correct datastores. A capacity manager tracks tenant usage of datastores in the registry store and then scales computing resources for each tenant in proportion to usage. The capacity manager also migrates tenant resources in response to catastrophic failures or upgrades. In this fashion, the multitenant deployment can adapt a single-tenant software application for multi-tenancy in a manner that is both transparent and secure for the tenant.

The invention is directed to methods and apparatus for call routing. The invention particularly relates to routing of calls, such as emergency calls, which are routed based on the location of a mobile subscriber in a cellular wireless network. The method comprises the steps of: at a first network node, receiving location information relating to a subscriber originating a call; at said first network node, determining initial routing information based on said location information; sending said location information from said first network node to a second network node; at said second network node, determining updated routing information based on said location information; sending said updated routing information from said second network node to said first network node; and at said first network node, routing said call based on said updated routing information. An advantage of the invention is that calls are routed based on more precise information, which is particularly important in the case of emergency calls.

A mechanism for routing content, e.g., an electronic document, an invention disclosure, etc., to a person or group of persons, e.g., a reviewer / review team, for review and evaluation of the electronic document. This mechanism involves receiving the content and analyzing the content to generate identifiers of subject matter of the content. Subject matter categories are then determined to be associated with the content based on the analysis. The mechanism then retrieves profiles for people that are authorized to review and evaluate content. These profiles include identifiers of categories of knowledge that indicate areas of knowledge held by an associated person. A person is then selected based on the subject matter categories and categories of knowledge. The content may then be routed to a client computing device associated with the selected person or group or persons.

A memory module includes a memory hub that couples signals to memory devices mounted on opposite first and second surfaces of a memory module substrate. The memory devices are mounted in mirrored configuration with mirrored terminals of memory devices on opposite surfaces being interconnected. A memory hub mounted on each module alters the configuration of address and / or command signals coupled to the memory devices depending upon whether the memory devices on the first surface of the substrate or the memory devices on the second surface of the substrate are being accessed. Alternatively, the configuration of the address and / or command signals coupled to mirrored memory devices may be altered by a register mounted on the substrate that is coupled to the memory devices or by a memory controller coupled directly to memory devices on one or more memory modules.

Disclosed is an improved proactive location based routing protocol for ad-hoc wireless networks. When a source node has a data packet to send to a destination node, the source node calculates an estimated future location of the destination node prior to forwarding a data packet to the destination node. The estimated future location may be based on the last known location, velocity and bearing of the destination node, as well as upon the estimated propagation delay (i.e., the estimated time it will take the data packet to reach the destination node after being transmitted by the source node). The source node routes the data packet by identifying which one of a plurality of its neighbor nodes is closest to the estimated future location of the destination node, and routes the data packet the identified neighbor node as an intermediate node along the route from the source node to the destination node. Further, the frequency of flooding broadcasts is based on the velocity of the network nodes. As the velocity of a network node increases, the rate at which the node broadcasts its location and mobility data also increases. The broadcast frequency of a network node may be dynamically adjusted as its velocity changes.

Maintaining session connectivity without termination when a mobile node is assigned a new layer-3 address upon moving from a old location to a new location. Routers between the mobile node and correspondent node are configured to perform network address translation (NAT) such that both the nodes can potentially use the old IP address in communicating with each other, and yet the packets are routed accurately using the new layer-3 address. As a result, the session may not be terminated at either of the nodes when the mobile node moves.

A mobile or cellular telecommunications network includes a plurality of terminals which are registered. The terminal may be fixed in position, such as a terminal in a vending machine. Alternatively, the terminal may be fixed to a vehicle used for sending an SOS message when the vehicle is involved in an accident. The terminal may be immobile, and therefore does not need to continually advise the network of its location. The terminal may not receive incoming calls or other communications. The terminals therefore may not require paging by the network. In the embodiments described, such terminals are assigned a special terminal type identifier which indicates to the network that these terminals do not require paging. The way in which the network interacts with the terminals is adjusted so that signaling to perform location updates is eliminated or at least reduced.

A method and system for managing the routing of traffic within a network develops a topological address space map of the network to enable a “best route” selection process. The network is comprised of a backbone connected to a plurality of peering partners. Points on the network monitor traffic flows. A central facility analyzes the traffic flows and routes within the network and performs intelligent routing management.Intelligent routing management ensures that traffic is properly routed through preferred routes on the network, and avoids inefficient routing. Intelligent routing management also selects new routes to be injected into the network in order to further improve the accuracy of the address space map of the network.

Methods and systems to provide a home system with information about a wireless unit roaming in a visited system based on information the wireless unit provides to the visited system. A mobile switching center (MSC-V) of the visited system receives the information from the wireless unit and routes a message to an international gateway. In response, the international gateway creates a new message or alters the original message, and transmits the new or altered message to a mobile switching center (MSC-H) of the home system. In response to receipt of the new or altered message, the MSC-H validates the wireless unit (if valid), creates a response to the new or altered message, and routes the response to the international gateway. The response may include an authorization period for the wireless unit and / or OCOS / TCOS information. In response, the international gateway creates a new response or alters the response, and transmits the new or altered response to the MSC-V. In response to receipt of the new or altered response, the MSC-V registers the wireless unit, provides the wireless unit with communication services in the visited system, or otherwise follows instructions in the new or altered response. If the wireless unit moves to an area served by a second MSC-V, the second MSC-V checks with the international gateway about the wireless unit. If an authorization period is in effect, the international gateway may provide a validation of the wireless unit to the second MSC-V without another message to the home system of the wireless unit.

When a delivery of packets is made between LMA and MN, an options header that enables identification of MN is added between the router (MAG), located between LMA and MN, and LMA so as to achieve appropriate routing. When MN moved, buffer transfer from previous access MAGa to new access MAGb is performed also by adding an options header to make delivery to MN. In this way, in network-based IP mobility protocol, when the mobile terminal (MN) or the control apparatus (LMA) serves as a compressor or decompressor to compress packets, fast handover can be realized when the MN moved, whereby it is possible to save the band for the last one hop, which is the narrowest band.
