Request tracking for analysis of website navigation
Provided are methods, apparatus and computer programs for enabling tracking of a user's sequence of Web Browser requests when navigating within a single Web site. Requests for access to resources within the Web site are compared with redirection criteria and, if matching, are redirected to a request tracker which determines a session identifier (generating a new session ID if required), then logs the request and then redirects the request back to the Web server for processing. This method uses a request tracker outside the scope of the Web server program, addressing the inability of many current Web servers to support cookies and avoiding major rewriting of the Web site. The resources within the Web site for which tracking is implemented are renamed on the Web server and the redirected requests are also renamed to be consistent with the renamed resources but to avoid repeated matching with the redirection criteria. This ensures that an incoming request is redirected to the tracker once only, and after forwarding back to the Web server is processed in a conventional way without repeated redirection to the request tracker. |

Search index format optimizations
A search index structure which extends a typical composite index by incorporating an index which is optimized for fast retrieval from storage and which eliminates data which is specific to phrase searching. Other data is represented in a manner which allows it to be calculated rather than stored. Associating variable length entries with logical categories allows their length to be inferred from the category rather than stored. Using delta values between document IDs rather than the ID itself generates a compact, dense symbol set which is efficiently compressed by Huffman encoding or a similar compression method. Using an upper threshold to remove large, and thus rare, delta values from the symbol set prior to encoding further improves the encoding performance. |

This method of temporally decorrelating the video sequence by finding the best matching blocks from past reference frames—motion estimation—makes up about 80% or more of the computation in a video encoder. In this patent disclosure, we define a method of searching only a very sparse subset of possible displacement positions (or motion vectors) among all possible ones, to see if we can get a good enough match, and terminate early. This sparse subset of motion vectors is preselected using prior knowledge and extensive testing on video sequences. |

Method and system for network communications via a configurable multi-use Ethernet PHY
Aspects of a method and system for network communications via a configurable multi-use Ethernet PHY are provided. In this regard, an Ethernet PHY may be configured based on characteristics of a network link over which the Ethernet PHY communicates, and a rate at which data is conveyed from a MAC to the Ethernet PHY may be controlled via a carrier sense signal of the MII. The carrier sense signal may be controlled based on a rate at which the Ethernet PHY transmits data over the network link. The Ethernet PHY may be configured based on a length of the network link and/or on a grade of the network link, where exemplary grades may comprise Cat-1 through Cat-7a cable. The Ethernet PHY may be configured into one of a plurality of modes comprising an Ethernet over digital subscriber line (DSL) mode, an extended reach mode, and a standard Ethernet mode. |

Elastic traffic marking for multi-priority packet streams in a communications network
Routers in a communications network mark packets of a multi-priority stream to establish a drop precedence of the packets during network congestion. For each packet received, a router employs one of two types of packet-marking mechanisms to associate low drop precedence with a high-priority, out-of-profile packet. One type, called “token bucket with loan bucket,” uses a token bucket to determine whether a packet is in conformance, i.e., in-profile, with a traffic profile and at least one loan bucket to determine whether a high priority, out-of-profile packet may borrow bandwidth. Another mechanism type, called “token bucket with color-exchange queue,” uses a color-exchange queue to delay packet forwarding for a fixed period. During this delay, a high-drop-precedence marking of an out-of-profile, high-priority packet may be exchanged with a low-drop-precedence marking of an in-profile, low-priority packet. The packet-marking mechanisms are useful in improving the quality of video viewing. |

Dynamic allocation of backhaul bearer services based on loading conditions
A method and system for dynamically allocating backhaul bearer service based on network loading conditions to help use backhaul-network resources more efficiently. A RAN detects an event relating to bearer service establishment for a given application. Then the RAN identifies a standard bearer service for the given application, where the standard bearer service has a first quality of service. After detecting the event, the RAN determines that a load of the backhaul communication network does not exceed a load threshold. Then, based on the determination that the load of the backhaul communication network does not exceed the load threshold, the RAN selects a bearer service for the given application, where the selected bearer service has a second quality of service that is higher than the first quality of service. Next, the RAN causes the selected bearer service to be established. |

Load balancing distribution of data to multiple recipients on a peer-to-peer network
Each peer node in a plurality has a different corresponding key value. Each of the nodes can broadcast one or more items to a plurality of recipient nodes. The recipient nodes are arranged into a list according to a key value order. The list is divided into two or more parts of approximately equal size, and each part of the list and the one or more items is forwarded to a recipient peer node corresponding to a first key value in that part of the list. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. This abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. |
