Decision Routing uses the discipline of Decisis to incorporate math, statistics, logic and economics to seek understanding of all relevant factors before deciding. Armed with the whole truth analysis and decision-making the “final judgment” can be surprisingly simple (or as Einstein put it – as simple as possible, but not simpler!)
Server load balancing using IP option field approach to identify route to selected server
InactiveUS20060233155A1Improve efficiencyData switching by path configurationRouting decisionField methods
A router for routing data from a client through load-balancing nodes to a selected load-balanced server among a plurality of servers in a network involves: receiving, at a last load balancing node associated with a selected server among the plurality of servers, a first packet of a server reply to a request from the client; storing identifiers of ingress interfaces on which the packet arrives, in a send path list for server load balancing, as the first packet of the server reply is routed from the last load balancing node to the client using hop-by-hop decisions; receiving subsequent packets of the client request; and forwarding the subsequent packets to the selected server only on a route that is defined by the send path list and without hop-by-hop routing decisions. Packet flows are routed from the same client to the same server without hop-by-hop routing decisions or repeated load-balancing decisions.

ActiveUS7007089B2Easy mappingImprove subsequent routingDigital computer detailsData switching networksGeneration processRouting decision
A routing method operative in a content delivery network (CDN) where the CDN includes a request routing mechanism for routing clients to subsets of edge servers within the CDN. According to the routing method, TCP connection data statistics are collected are edge servers located within a CDN region. The TCP connection data statistics are collected as connections are established between requesting clients and the CDN region and requests are serviced by those edge servers. Periodically, e.g., daily, the connection data statistics are provdied from the edge servers in a region back to the request routing mechanism. The TCP connection data statistics are then used by the request routing mechanism in subsequent routing decisions and, in particular, in the map generation processes. Thus, for example, the TCP connection data may be used to determine whether a given quality of service is being obtained by routing requesting clients to the CDN region. If not, the request routing mechanism generates a map that directs requesting clients away from the CDN region for a given time period or until the quality of service improves.

Method and apparatus for routing data to a load balanced server using MPLS packet labels
InactiveUS6856991B1Improve efficiencyDigital data processing detailsDigital computer detailsRouting decisionNetwork packet
A method of routing data to a load-balanced server through a network having one or more load-balancing nodes is disclosed. The first packet of a client request is received at one of the load-balancing nodes, which stores information identifying a flow associated with the packet and an incoming interface identifier. The node then makes a server load-balancing decision and stores an outgoing interface identifier. When the packet reaches the last load-balancing node before the selected server, that last node also requests an MPLS label to uniquely identify the flow, connection and route. The label is stored in a mapping at the last node that associates the label with the flow and interface identifying information. The packet is routed to the selected server. The first server response packet is switched hop-by-hop and the MPLS label is stored at each node traversed by the response packets, in association with a flow identifier and incoming and outgoing interface identifiers. For all other packets in the request and response, nodes fast-switch the packets based on the label mappings. As a result, packet flows are rapidly routed from the same client to the same server without time-consuming hop-by-hop routing decisions or repeated load-balancing decisions.

Caching with selective multicasting in a publish-subscribe network
ActiveUS7672275B2Efficient routingOvercome disadvantagesData switching by path configurationWireless commuication servicesRouting decisionEncapsulated data
Packet routing via payload inspection at routers in a core of a distributed network. Packets include subjects and attributes in addition to routing information. The subjects correspond with particular types of content for subscriptions, and the attributes encapsulate the data or content. The routers store filters corresponding with subscriptions to content. Upon receiving a packet, a router inspects the payload section of the packet containing the attributes in order to retrieve the attributes and apply them to the filters for the subscriptions. If an attribute satisfies a filter, the packet is routed to the next link. If the attributes do not satisfy the filters, the router discards the packet. These routing decisions are distributed among routers in the network core. The router locally caches the data in the network core.

Integrating distributed computing environment remote procedure calls with an advisory work load manager
InactiveUS6067580AResource allocationMultiple digital computer combinationsAmbulatory systemDistributed Computing Environment
Distributed computing environment (DCE) remote procedure calls (RPCs) are integrated with an advisory work load manager (WLM) to provide a way to intelligently dispatch RPC requests among the available application server processes. The routing decisions are made dynamically (for each RPC) based on interactions between the location broker and an advisory work load manager. Furthermore, when the system contains multiple coupled processors (tightly coupled within a single frame, or loosely coupled within a computing complex, a local area network (LAN) configuration, a distributed computing environment (DCE) cell, etc.), the invention extends to balance the processing of RPC requests and the associated client sessions across the coupled systems. Once a session is assigned to a given process, the invention also supports performance monitoring and reporting, dynamic system resource allocation for the RPC requests, and potentially any other benefits that may be available through the specific work load manager (WLM).

A method and system for communicating information includes evaluation regarding routing of calls performed at a call control point in an ITSP and / or wireless network. A PIC identity associated with another party's preferences is acquired and sent to the call control point. The PIC identity identifies the type of the carrier network (e.g., circuit switched or VoIP) and is used to make further routing decisions. If a circuit-switched carrier is identified, the IP homing leg is terminated at the voice gateway in the recipient's HPLMN and information is sent over to the GMSC where normal, circuit-switched routing procedures. If a VoIP carrier is identified then the called user's roaming number is retrieved from the HLR, and the call is further routed directly over the IP domain towards a voice gateway at the visited network minimizing the number of transcodings. Additional transcoding steps can be avoided if a single encoding is agreed upon according to “tandem free operation” (TFO). Combining inband signaling through the telephony exchanges and out-of-band signaling in the IP network it is possible to achieve, for a mobile subscriber, one encoding and one decoding of a voice.
