Abstract: Systems and methods are disclosed that facilitate minimizing data transfer from a post office protocol (POP) server to a client device by employing a date filter with a predefined date range and applying a message body size threshold above which only a message header will be downloaded to conserve bandwidth and/or memory space on the client device. A user can request download of a message for which only a message header was originally downloaded if the header comprises information of interest to the user.

Abstract: Techniques to store entries so that minimal sequential memory accesses are used to determine all relevant entries. Entries may be grouped into blocks. The order of entries within blocks may be set in a manner so that entry locations can be determined using an input value, such as a destination address. Blocks may be ordered into levels. Blocks of each level may be stored in consecutive storage locations. Accordingly, entry locations may be determined and retrieved with minimal sequential memory accesses by storing entries in a predetermined manner.

Abstract: Sessions states within virtual machine (VM) environments are maintained. Each VM environment hosts a guest operating system (OS) and one or more application programs running. The guest OS and the application computer programs of each VM environment constitute a session. A connection broker maintains a state machine as to states of the sessions and permits transitions among the states in response to messages, commands, and internal decisions. Different types of agents may send the messages, and the commands. The states of the sessions may include a pending state and a number of other states. The pending state is an interim state that indicates a session is being transitioned from one of the other states to another of the other states. These other states may include an offline state, an online-down state, an online-up state, a suspended state, an active state, an idle state, a disconnected state, and a failed state.

Abstract: A method for controlling a service providing device includes the steps of determining whether the service providing device has already acquired a global address of a client station accessing the service providing device, requesting the client station to notify the global address of the client station when the determining step determines that the service providing device has not yet acquired the global address, and providing the client station with different services based on whether or not the client station notifies the service providing device of the global address in response to the request at the requesting step.

Abstract: Method, apparatus and article of manufacture for acquiring a buffer after data from a remote sender (e.g., client) has been received by a local machine (e.g., server). Because the client data has already been received when the buffer is acquired, the buffer may be sized exactly to the size of the client data. In general, the buffer may be caller supplied or system supplied.

Abstract: Chat messages in a chat session may be displayed in a timeline view. Messages are displayed in a first display region. Timestamps of the chat messages are displayed in a second region. The messages are aligned with their respective timestamps, akin to a timeline. Timestamps for all messages need not be displayed; a timestamp may be omitted if the corresponding message occurs in the “same” time as another message. Breaks of no messaging activity that are longer than a predefined amount of time are shown with graphical objects such as a line. The objects also indicate the length of the break.

Abstract: A wireless communications system incorporates a plurality of synchronized wireless units. Each unit minimizes energy requirements by entering a low current, inactive, state between synchronizing signals.

The manner in which the plurality of grouped cluster members is grouped reduces a coefficient of variation on each cluster member in the server cluster. The process executes a method in a selected cluster member associated with the method in response to receiving a call for the method.

Abstract: Methods and apparatuses are provided for detecting traffic patterns in a data network. A sequential hashing scheme can be utilized that has D hash arrays. Each hash array i, wherein 1?i?D, includes Mi independent hash tables each having K buckets, with each of the buckets having an associated traffic total. Each of the keys corresponds with a single bucket of each of the Mi independent hash tables of each hash array i. The keys of the data network are partitioned into D words. As traffic is received for a key, a traffic total of each bucket that corresponds with a key is updated. The hash arrays can then be utilized to identify high traffic buckets of the independent hash tables having a traffic total greater than a threshold value. The high traffic buckets can be used to detect significant traffic patterns of the data network.

Abstract: Methods and apparatus for performing automatic service selection in a client are disclosed, where the client supports a protocol for calling a subroutine on a remote server.
