Abstract: A hybrid network device can implement functionality for automatic path selection and modification in a hybrid communication network. The hybrid network device can select an initial network interface from a plurality of network interfaces for transmitting a packet stream. In response to determining that the medium utilization of the initial network interface exceeds the medium utilization threshold, the hybrid network device can identify one or more packet streams originating from the initial network interface to shift to corresponding one or more alternate network interfaces. The hybrid network device can attempt to reduce the medium utilization of the initial network interface below the medium utilization threshold while maintaining the medium utilization of the one or more alternate network interfaces below the corresponding medium utilization thresholds.

The information processing apparatus refers to the list of the print job and the status and the list of the print job and the information and stops the transmission of a print job if the number of jobs that have already been transmitted to the printing apparatus by the information processing apparatus is equal to or exceeds a predetermined threshold value or if the number of print jobs retained by the printing apparatus is equal to or exceeds a predetermined threshold value.

Abstract: Solutions are provided that allow a network device to apply flow control on the MAC layer while taking into account the priority of the frame of traffic. This may be accomplished by generating a frame indicating that traffic flow should be paused, while utilizing a new opcode value, or alternatively by utilizing a new type/length value (possibly combined with a new opcode value). A receiving device may then examine the fields of the frame to determine whether it should use priority-based pausing, and then examine other fields to determine which priority-levels to pause and for how long. This allows for improved efficiency in flow control on the MAC layer.

Abstract: Functionality available on an enterprise server is applied to HTML content from a remote server. HTML content is collected from remote servers including remote markup tags upon request from an end user. The HTML content for the remote markup tags is parsed and converted to content formatted for enterprise server functionality. The converted content is executed at the enterprise server. Remote server and enterprise server data are then transmitted to the end user. Tags and/or libraries may be extensible, such that they may be created or modified, and the tags may or may not be included within a supplied library of tags and/or a created library of tags, or any combination thereof.

Abstract: Host machines and other devices performing synchronized operations can be dispersed across multiple racks in a data center to provide additional buffer capacity and to reduce the likelihood of congestion. The level of dispersion can depend on factors such as the level of oversubscription, as it can be undesirable in a highly connected network to push excessive host traffic into the aggregation fabric. As oversubscription levels increase, the amount of dispersion can be reduced and two or more host machines can be clustered on a given rack, or otherwise connected through the same edge switch. By clustering a portion of the machines, some of the host traffic can be redirected by the respective edge switch without entering the aggregation fabric. When provisioning hosts for a customer, application, or synchronized operation, for example, the levels of clustering and dispersion can be balanced to minimize the likelihood for congestion throughout the network.

Abstract: Systems and methods for providing the progressive download of media content using techniques that preferentially identify and use periods of surplus network capacity to maintain the content delivery. A buffer of a receiving system is maintained and pre-filled with enough content to bridge playback intervals where a network is unable to deliver content as fast as it is played out. Content delivery does not impact other users' applications and use of the network and its resources since content is preferentially sent when surplus network capacity exists in the network. When no surplus network capacity is available, a user requesting content may be given the option to continue the delivery in the background so that the content may be played at a later time. The user may then resume their playback experience once the content has been completely delivered using surplus network capacity as it becomes available.

Abstract: Properties of data transmission are measured in a telecommunications network (2) comprising an access network segment (6) and a core network segment (4). A packet switched network endpoint device (10) in communication with the access network segment passively monitors data throughput between the telecommunication network and the endpoint device and conducts active tests of data transmission latency and data transmission loss by exchanging active test data packets with an active test server (8). Test result data is transmitted to the active test server in active test data packets (106, 118), avoiding additional network traffic. Active tests are conducted from the application layer. The resulting metrics accurately represent the experience of users of the endpoint devices.

Abstract: A computer supports generating a model of transactions in which services are processed in multiple layers. The computer refers to start times and end times of processings, which are invoked and generated from another processing in the services, of the same server to calculate time intervals between the processings. The computer generates possible thresholds indicating thresholds that are possible criteria for grouping the processings according to the time intervals between the processings. The computer puts together, for each of the generated possible thresholds, consecutive processings, in which the time intervals between the processings are equal to or smaller than the possible threshold, into the same group to generate a group that the processings belong to. The computer divides a group, among the generated groups, without a processing serving as an invoker into processing-by-processing groups. The computer determines the possible threshold with the least number of groups as the threshold.

When finally the new reference bitrate has been reached, the base station (RBS) requests a linear increase of the bitrate associated with the air interface.

Abstract: A streaming server sends a multimedia stream for delivery by a hybrid unicast-broadcast delivery network to a mobile terminal. To assist that mobile terminal change access delivery from unicast to broadcast, the streaming server sends multimedia content timing information that indicates one or more interstices in the content of the multimedia stream. The mobile terminal receives such multimedia content timing information upon receiving the multimedia stream by unicast. Although the mobile terminal determines the same multimedia stream is also available by broadcast, the mobile terminal initiates a change from unicast to broadcast during an interstice. Because the mobile terminal delays the access change until an interstice, any data loss resulting from the access change has a minimal effect on a subscriber's experience of the multimedia content. Moreover, regular occurrence of interstices ensures that such change will not be significantly delayed, and thus, neither will use of broadcast.

The method is characterized in that the application is communicating with a local network controller, wherein the network controller is receiving a UE-related and/or session-related parameter (LID—Local Identifier) from the application for locating a UE and/or a specific session within the local network based on the received parameter. Further, an according network is claimed, preferably for carrying out the above mentioned method.

Abstract: Methods and protocols coordinate enforcement of application traffic shaping limits within clusters of middleware appliance information handling systems (MA IHSs). The protocols dynamically set the local traffic shaping requirements at each entry point of an MA IHS. Each MA IHS receives from other MA IHSs runtime statistics containing local shaping requirements and rates of requests. The method uses runtime statistics to measure performance against specified traffic shaping goals, and based on this comparison uses unique protocols to dynamically adjust the local shaping requirements in each MA IHS. The method may eliminate the need to statistically bind service domains to particular MA IHSs. Additional MA IHSs activate and/or deactivate service domains to accommodate service domain (server farm) CPU resource demands.
