The present invention provides an email multicasting device which changes a distribution interval of emails dynamically in accordance with the number of emails to be multicast. The email multicasting device pre-stores on a client basis, mobile numbers of users which are destinations of an email. The email multicasting device, when receiving mail contents from a client, creates plural emails each of which contains the mail contents and one of mobile numbers associated with the client, and queues ...

A communication node of the present invention automatically transmits original and duplicate packets over different paths in a communications network to improve delivery reliability of the packet and to decrease packet delivery time. A packet is typically marked for reliable transmission by the application layer of a source node, while a routing agent module within the node IP layer processes the marked packets. The marked packets are transmitted over redundant (e.g., primary and secondary) netw...

A processor node of a network is provided which includes one or more processors and a virtualized channel adapter. The virtualized channel adapter is operable to reference a table to determine whether a destination of the communication is supported by the virtualized channel adapter. When the destination is supported for routing via hardware, the virtualized channel adapter is operable to route the communication via hardware to at least one of a physical port and a logical port of the virtualize...

A method and system for establishing a connection with a server after a connection has been broken is provided. A connection system in a service layer of a client detects that a connection between the client and the server has been broken. Upon detecting the broken connection, the connection system of the service layer automatically attempts to re-establish an application-level connection to the server. If the connection system can re-establish an application-level connection to the server, then...

A method for delivering electronic services in a personal area network (PAN) can include providing a kiosk in a publicly traversable area. The kiosk can be configured to deliver electronic services over short-range radio communications links to wireless devices in a personal area network (PAN). The kiosk also can be configured to communicate over an existing physical communications link medium. A PAN can be established in the publicly traversable area. Electronic services can be selectably retri...

Techniques are presented for assigning reputations to email senders. In one implementation, real-time statistics and heuristics are constructed, stored, analyzed, and used to formulate a sender reputation level for use in evaluating and controlling a given sender's connection to an message transfer agent or email recipient. A sender with an unfavorable reputation may be denied a connection before resources are spent receiving and processing email messages from the sender. A sender with a favorab...

A method and apparatus that interactively determine which data is exchanged between two networks or devices operating on the networks and the order in which the data is transferred. One of the networks can be a vehicle area network. The determination is capable of being based on one or more data criteria, including file size, user access, device interaction, user preferences, history of use, and so on. The available time in which to communicate is forecasted so that the appropriate data can be t...

A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, a mechanism for improving connection establishment in a system utilizing an offload network adapter is provided. The connection establishment mechanism provides the ability to offload connection establishment and maintenance of connection state information to the offload network adapter. As a result of this offloading of connection establishment and state information ...

Message header spam filtering is described. In an embodiment, a message is received that includes header entries arranged in an ordered sequence which indicates a path by which the message was communicated. The header entries are parsed to categorize each header entry as a header type where the header types are listed in the ordered sequence. A quantity of each different header type is determined, and a determination is made as to whether the message is likely a spam message based at least in pa...

One embodiment disclosed relates to an apparatus for routing packets towards destination addresses. The apparatus includes at least a routing table and a route fragment cache. Each route in the routing table includes a network address, a mask, and a corresponding forwarding information. Each route fragment in the route fragment cache includes a section of a route from the routing table. The route fragments are such that no route fragment in the route fragment cache intersects any route in the ro...
