An assured message delivery system with resiliency receives messages from publishing client(s) and delivers them to subscribing clients. A primary system delivers the messages during normal operation. A secondary system mirroring the configuration of the primary system takes over responsibility for delivering the messages in the event of failure of the primary system. The secondary system is connected to the primary system over a communications link. The primary system sends copies of the messages to the secondary system over the communications link. The secondary system stores replicate messages and sends acknowledgement messages back to the primary system.

Replication in assured messaging system

A method of propagating multicast subscription and routing information between routers in a network, and constructing forwarding tables in the routers, allowing providers of the data (the publishers), and the multicast recipients of the data (the subscribers) to be decoupled from and have no knowledge of one another. This is done without the need to maintain (Source Network, Published-Multicast-Group) State in the routers, for a highly scalable solution in those applications where there is a possibility for a large, or infinite number of Published-Multicast-Groups, and in those applications where messages are being routed by content, so it is impossible to identify published-multicast-groups.

Subscription Management and Routing Protocol (SMRP) and Method

A method and apparatus for converting documents from one format to another in a speed efficient way involves a hardware module which implements several operating pipeline stages which work in parallel. The transformations are supplied and decomposed into sequences of control units. The transformation of documents consists of applying control unit sequences to input documents. The control units are themselves executed by a set of dedicated hardware resources. Furthermore the pipeline is capable of operating on more than one document at a time. Fast document transformation is a key capability of document processing systems. The use of parallel processing techniques and hardware that implements highly specialized transformation resources make this invention particularly scalable for its use in large, high speed content networks.

A method of managing a content routed network, involves distributing published documents through said network for delivery to subscribers; maintaining data logs pertaining to said published documents at different points in the network; and correlating the data logs to obtain information about the operation of the network.

Clay stabilizing agents used in fracturing fluids produce noxious odours, raise environmental concerns or are less than effective in subterranean formations of low permeability. Disclosed herein is an alternate stabilizing agent comprising at least one organic amine selected from the group consisting of primary diamines with a chain length of 8 or less and primary alkyl amines with a chain length of 4 or less. The organic amine is admixed with the fracturing fluid in an amount not less than 0.03% by volume of the fluid and typically in the range of from about 0.06% to 0.3% by volume of the fluid.
