摘要： An embodiment of a method includes receiving a request for the content from a requester, retrieving the content from a media access server, and while retrieving the content from the media access server, simultaneously streaming the content to the requester. An embodiment of a system includes an edge server having a media streaming server configured to receive the request and stream the specified content to a requester from a local memory, and a stream caching server configured to retrieve the requested content from a media access server while the media streaming server is streaming at least a specified portion of the content, and wherein the stream caching server is further configured to store the retrieved content in a local cache and notify the media streaming server that content is stored in local cache.

摘要： A transmission relay circuit, a broadcast signal relay method, and a sign al detection device are disclosed. Preferably, the transmission relay circui t includes a microcontroller, a broadcast signal sensing and discerning circ uit configured for determining the broadcast signal selected from a group co nsisting of (NTSC, ASI, DS-3, SDI, and HD-SDI signals). The method preferabl y includes the steps of determining a signal type, directing the signal to a n analog broadcast signal processing circuit when the signal is determined t o be to be an analog video signal, directing the signal to a digital broadca st signal processing circuit when the signal is either a digital video signa l, or a digital video transport signal, and relaying the processed signal to a local loop provider. The detection device preferably includes at least a multi-layer printed circuit board with an isolation/buffer amplifier and ter minator, and a signal detection circuit for detecting and determining the br oadcast signal type.

摘要： There is provided herein a system and method for automatic configuration of data routings for use with electronic data such as phone calls, faxes, et c. In the preferred embodiment, when more than one carrier might potentially terminate the transmission, the carriers are ordered based on some screenin g criterion (e.g., transmission price). Data transmissions are then assigned to the carriers based on the sorting order, with the second place and lower carriers (e.g., the higher priced carriers) not being selected unless the f irst carrier cannot complete the transaction. The switch instructions necess ary to implement this scheme are generated automatically.

摘要： Examples of the present disclosure relate to hostname pre-localization. In examples, a service uses a content distribution network (CDN) to provide at least a part of the computing functionality associated with the service. A pre-localized hostname may be used to direct the client computing device to a specific edge server of the CDN that is associated with the computing functionality. In examples, a service receives an initiation request from a client computing device for the computing functionality provided by the CDN. The service generates a pre-localization request comprising pre-localization information and provides the pre-localization request to the CDN. Accordingly, the CDN generates a pre-localized hostname associated with an edge server based on the pre-localization information. The pre-localized hostname is provided to the service, which is then provided to the client computing device, thereby directing the client computing device to the specific edge server of the CDN.

摘要： In an embodiment, a method exchanges routing data within a network including control and forwarding on separate devices. In the method, a first reachability information session is established between a forwarding device and a first control device and a second reachability information session is established between the forwarding device and a second control device. Also, a third reachability information session is established between the forwarding device and an external routing device. Finally, advertisements are exchanged between the first and second reachability information sessions and the third reachability information session such that the first and second control device appear to the external routing device to be a single device. System and computer program product embodiments are also disclosed.

摘要： Examples described herein relate to apparatuses and methods for managing communications within a supercluster or across superclusters, including a first supercluster having a plurality of first machines and a publish-subscribe (Pub-Sub) channel to which each of the plurality of first machines is subscribed. A second supercluster has a plurality of second machines and a bridge between the first supercluster and the second supercluster. A first machine is configured to receive, via the bridge, an availability status and resource allocation information of each second machine and publish, on the Pub-Sub channel of the first supercluster, the availability status and the resource allocation information.

摘要： A content provider has a plurality of content provider domain names, and a content delivery network (CDN) allocates a plurality of CDN domain names to the particular content provider. The content provider domain names are mapped to the CDN domain names. CDN domain names are bound to corresponding CDN clusters. The binding of the of CDN domain names to corresponding CDN clusters is modified.
