摘要： A method and apparatus for providing quality of service parameters for transmissions of multicast streams on a cable network is provided. A cable network headend connects an external network to a hybrid fiber coax or cable network. The cable network headend maintains a table of cable modems with entries associating each cable modem with one or more quality of service parameters. Virtual cable modem entries are created for multicast streams when indications of quality of service for multicast streams are received by the cable network headend. Multicast packets arriving at the cable network headend are processed using the stored quality of service parameters for the corresponding multicast stream. The multicast packets may then be transmitted, queued, or dropped depending on the specified parameters and traffic shaping or policing algorithms.

摘要： In one embodiment, a list of source identifiers is maintained at a virtual switch. These source identifiers are allowed to send packets through the virtual switch to ports in a private virtual local area network (PVLAN). When a packet is received at the virtual switch from a particular source destined for a particular port in the PVLAN, the virtual switch determines whether a particular identifier associated with the particular source matches one of the source identifiers in the list. If that particular source identifier is not on the list, the packet is prevented from being forwarded to the particular port in the PVLAN.

摘要： Location-based filtering and advertising enhancements for merged browsing of network content are described herein. In various embodiments, a client device may obtain its geographic location and provide that location to a server for filtering by the server of network content fragment suggestions based at least in part on the location. The client device may then receive some or all of the filtered suggestions for utilization in merged browsing. In some embodiments, a server may further receive an indicator of content being browsed. In response, the server may determine network content fragment suggestions, and may also determine an additional suggestion or prioritize a suggestion based an advertiser's interest. The server may then provide the suggestions and/or prioritization to the client device. In various embodiments, the server may also provide the advertisement(s) for display in a user interface of the client device along with the (prioritized) suggestions.

摘要： Redundant application network appliances using a low latency lossless interconnect link are described herein. According to one embodiment, in response to receiving at a first network element a packet of a network transaction from a client over a first network for accessing a server of a datacenter, a layer 2 network process is performed on the packet and a data stream is generated. The data stream is then replicated to a second network element via a layer 2 interconnect link to enable the second network element to perform higher layer processes on the data stream to obtain connection states of the network transaction. In response to a failure of the first network element, the second network element is configured to take over processes of the network transaction from the first network element using the obtained connection states without user interaction of the client. Other methods and apparatuses are also described.
