Abstract: Users are assigned to virtual groups. Virtual groups are associated with server assets. Achieving load-balancing during the delivery of linear multimedia content, for example, may be achieved through reassigning users to different virtual groups. Server assets can include server clusters that are assigned to the virtual groups. New hardware can be added to server assets without having to directly associate users to the new hardware.

Abstract: A mechanism for achieving resiliency and load balancing for SIP application services and, in particular, in geographic distributed sites. A method performs a distribution of SIP requests among SIP servers, where at least two sites with a load balancer in each site is configured. The method includes receiving a SIP request by a first load balancer in a first site; determining whether the SIP request should be redirected to a second site; and redirecting the SIP request to an address of a second load balancer in the second site. The invention also includes a SIP proxy including a receiving unit receiving SIP requests; a load balancing unit distributing SIP requests between SIP entities; and a health monitoring unit verifying availability of the SIP entities. The SIP proxy may further be configured with a proximity measuring unit determining a proximity to a SIP entity.

Abstract: The invention relates to a method for network domain name resolution, the domain name comprises a first portion domain name and a second portion domain name, and the resolution method comprising following steps: In a first network system, resolving the first portion domain name into a first network address; In the first network system, searching for a first network node corresponding to the first network address according to the resolved first network address; In a second network system, resolving the second portion domain name into a second network node address, and the domain name resolution system of the second network system being independent of the domain name resolution system of the first network system. As the resolution structure of the domain name in the Intranet is independent of the resolution structure of the domain name in the Internet, the IP address of the Intranet will not occupy the IP address resource of the Internet.

Abstract: A framework for content delivery includes a content distribution manager operable to select content for distribution in response to a request for content. The selection of content may be made based in part on scheduling information associated with sources of available content and selected by content providers. The selection may further be based in part on a content selection policy selected by publishers who initiate requests for content.

Abstract: When a client requests content from a Content Delivery Network based system (or other system), that content is typically provided from a source capable of providing high performance to that client. However, if the system determines that the client is using a slow connection, then the content is transmitted to the client from a source that provides a lower performance to that client, with a minimal or no performance penalty observable by the user of the client.

Abstract: When a client requests content from a Content Delivery Network (or other system), a first portion of the content is requested from a source capable of providing high performance to that client. When the client has a sufficient amount of the content to perform its function, then additional portions of the content can be requested from a source that provides a lower performance to that client with a minimal or no performance penalty to the user of the client.

Abstract: Embodiments of the present invention provide a method, a switch, and a system for processing a message, which relate to the field of communications technologies, and are used to improve real-time performance in ARP request processing when APR request flooding occurs. An access switch generates a mapping table in a communication process between an intra-group server and a DHCP server, where the mapping table includes mapping between the intra-group server and address information of the intra-group server; receives an ARP request sent by a source server, where the ARP request is used to indicate a destination server that the source server needs to access; searches the mapping table according to the ARP request, and when the address information of the destination server is obtained according to the mapping table, sends the address information of the destination server to the source server.

Abstract: A system and method for efficient and private peer-to-peer file sharing consists of ascribing a uniquely identified and anonymous link (an “edgelink”) to any file or set of files on a peer computer. The link is registered with a publishing server along with continuously updated connectivity information about the peer without registering any identifying information about the file. A peer recipient is able to access the link, receive connectivity information about the publishing peer from the server, and then receive the file from the publishing peer without file content passing through the server, mediating any intermediary NAT devices without requiring any manual or automatic device reconfiguration.

Abstract: A data transfer system of this invention includes a plurality of transfer apparatuses (11-14) and a control apparatus (10). On condition that data transfer to a transfer apparatus of a transmission destination is completed before a requested transfer completion time, the control apparatus (10) builds a data transfer tree serving as a data transfer path from a transfer apparatus of a transmission source to the transfer apparatus of the transmission destination. Each of the transfer apparatuses (11-14) transfers data in accordance with the tree. This allows to guarantee to complete transfer to transfer apparatuses of a plurality of transmission destinations up to a requested transfer completion time even when a transfer apparatus of one transmission source transfers a file to the transfer apparatuses of the plurality of transmission destinations by multicast.

Abstract: Automatically determining a link speed between link partners using a multispeed fiber module. An embodiment solves the problem of how to determine the highest common link speed between short range (SR)/long range (LR) fiber link partners when at least one of the link partners is using a multispeed fiber module. In an embodiment, a multispeed fiber module comprises a module that is capable of both 10 gigabit (GB) per second Ethernet and 1 GB per second Ethernet or lesser data transfer speeds over a fiber optical link. In an embodiment, the method comprises trying each link speed in a known succession, from highest supported speed to lowest supported speed. In an embodiment, an initiator link partner “blinks” a transmit laser, which alerts the link partners that a link speed determination session is being initiated. By automatically determining link speed, the user is relieved of the necessity to manually configure the link speed.

Abstract: Various embodiments of a system and method for assignment and switching of content sources for a streaming content session are described. Embodiments may include the generation and use of content source rankings for improving playback quality of content streams. In embodiments, a merchant system may collect and aggregate multiple quality metrics for different content streams that various content sources provide to various clients. The merchant system may utilize the quality metrics to generate rankings of content sources for clients. The merchant system may provide such rankings to clients to improve the content stream playback experience on the client. For instance, at content acquisition time, a client may request a content stream from a content resource ranked highest on a content source ranking provided by the merchant. If the content stream degrades, the client may source subsequent portions of the content stream from another highly ranked content source of the ranking.

Abstract: A session transfer procedure not for all ongoing multimedia components but for some media components in a wireless communication system and an apparatus for the same are provided. In a partial session transfer procedure, a user equipment establishing a first session to transmit a plurality of media components transmits a partial attach request message to a mobility control entity of a network core. The partial attach request message may be an attach request message whose attach type is set to ‘partial handover’. Upon receiving an attach accept message containing information regarding a gateway of the network core from the mobility control entity, a second session is established with the gateway by using the gateway information. After the establishing of the second session, the user equipment does not release the previously established first session.
