Abstract: Association information is used to build association trees to associate base pages and embedded objects at a proxy. An association tree has a root node containing a URL for a base page, and zero or more leaf nodes each containing a URL for an embedded object. In most cases, an association tree will maintain the invariant that all leaves contain distinct URLs. However, it is also possible to have an association tree in which the same URL appears in multiple nodes. An association tree may optionally contain one or more internal nodes, each of which contains a URL that is an embedded object for some other base page, but which may also be fetched as a base page itself. Given a number of association trees and a base-page URL, a prefetch system finds the root or interior node corresponding to that URL (if any) and traverses the tree from that node, prefetching URLs until the URL of the last leaf node is prefetched. The prefetching starts the process of bringing over the various embedded objects before the user or program would ordinarily fetch them.

Abstract: Techniques are provided for incrementally maintaining an XML index built to access XML data that is encoded in binary XML form. Rather than delete and reinsert index entries of all the nodes of a modified XML document, only the index entries of the affected nodes are modified. Consequently, the order key values stored in the index may become inconsistent with the current hierarchical locations of the nodes to which the order key values correspond. Techniques are described for resolving the inconsistencies, and for addressing additional problems that result when the XML index is path-subsetted.

Abstract: Methods, systems, and apparatus provide efficient and flexible networking quality of service as well as transport protocol design. A hybrid transport/network quality of service (HNTQ) scheme improves the performance of TCP over specific links or network paths that are subject to high latency, a high bandwidth-delay product, high packet loss, and/or bit errors. A callback mechanism can be used between a packet scheduler and a transport module to control the transmission rate of packets across one or more connections or links.

Abstract: An XML document can be represented in a compact binary form that maintains all of the features of XML data in a useable form. In response to a request for a modification (e.g., insert, delete or update a node) to an XML document that is stored in the compact binary form, a certain representation of the requested modification is computed for application directly to the binary form of the document. Thus, the requested modification is applied directly to the persistently stored binary form without constructing an object tree or materializing the XML document into a corresponding textual form. Taking into account the nature of the binary form in which the document is encoded, the bytes that actually require change are identified, including identifying where in the binary representation the corresponding actual changes need to be made.

Abstract: Systems and techniques for distributed broadband network gateway for maximizing IPv4 address utilization. A dynamic host configuration protocol (DHCP) offer message is received by a distributed broadband network gateways (BNG) connected to a network. The DHCP offer message may have been forwarded from a DHCP server. The DHCP offer message is modified to replace an option 1 subnet mask with a 32-bit subnet mask and replace an option 3 router address with an internet protocol address of the distributed BNG to create a modified offer message. The modified offer message is transmitted to a user computing device. A route with a 32-bit subnet mask for the user computing device is advertised to other routers internal to the network of the broadband service provider.

Abstract: A method and apparatus are provided for split-terminating a secure client-server communication connection when the client and server perform mutual authentication by exchanging certificates, such as within a Lotus Notes environment. When the client submits a certificate to the server, an intermediary device intercepts the certificate and submits to the server a substitute client certificate generated by that intermediary. A certificate authority's private key is previously installed on the intermediary to enable it to generate public keys, private keys and digital certificates. With the private key corresponding to the substitute certificate, the intermediary extracts a temporary key from a subsequent server message. The intermediary uses the temporary key to read a session key issued later by the server. Thereafter, the intermediary shares the session key with another intermediary, and together they use the session keys to access and optimize (e.g., accelerate) messages sent by the client and the server.

Abstract: A simulator simulates routing system protocols to build routing tables corresponding to a modeled network, and a comparator compares the routing tables in the actual network to these simulator-created routing tables. Because the modeled system represents a fault-free version of the actual system, and assuming that the modeled routing system protocols are representative of the algorithms used in the actual routers, these simulator-produced routing tables can represent steady-state routing tables that should be present in the routers of the actual network at steady state. By querying each router in the actual network for its routing table and comparing each routing table to the corresponding simulator-produced routing table, any differences from the steady state can be identified.
