An electronic device, while providing a first playlist for playback by a media device, maintains a play queue for a first user that is initially populated with a list of media content items to be played by the media device, the initially populated list of media content items including media content items distinct from the first playlist and selected by the first user and media content items from the first playlist. The electronic device receives a request to change playback from the first playlist to a second playlist different from the first playlist. In response to the request to change the playback from the first playlist to the second playlist, the electronic device maintains, in the play queue, the media content items selected by the first user while changing playback from the first playlist to the second playlist.

System and method for use of cyclic play queues in a media content environment

In accordance with an embodiment, described herein is a system and method for use of cyclic play queues in a media content environment. A cyclic list data structure that can be initially populated with a list of media content items to be played at a media device, exposes a cyclic list of sequences of media content items, and supports operations to modify portions of the cyclic list to provide a cyclic play queue of media content items. When changes are made to an underlying play queue or context, the system performs a three-way merge of sequences of media content items within the cyclic list, to provide a modified play queue, for example with the left sequence being an updated playlist, and the right sequence being a patch window that reflects a user's changes to the play queue.

A method and a first device () of a switched network (), for managing data frames received, at a first port, from a second device () are disclosed. The first device () handles the first port and a second port for transfer of data frames between the first and second devices (). The first device () is addressable by a Media Access Control address, 'MAC address', associated with the first port. The first device () receives (), from the second device (), at least one data frame at the second port. The first device () sends (), on the first port, a message including the MAC address associated with the first port.

A routing device and a further routing device of a switched network form a virtual router and are addressable by a virtual Media Access Control (MAC) address. The further routing device receives at least one data frame and sends, to the routing device, a request instructing the routing device to send an alert message for conveying information about the virtual MAC address throughout the switched network.

Managing data frames in switched networks

A method and a routing device () for managing data frames as well as a method and a further routing device () for managing data frames are disclosed. The routing device () is addressable by a virtual Media Access Control address, 'virtual MAC address', for assignment to routers. The routing device () sends () a data frame comprising a source MAC address field, which includes a unicast MAC address of the routing device (). The routing device () sends () a message including information about the virtual MAC address. The routing device () is configured to send, in a periodic manner, a periodic message for conveying information about the virtual MAC address throughout the switched network (). In another embodiment, the further routing device () receives () at least one data frame. The further routing device () sends () a request which instructs the routing device () to send an alert message for conveying information about the virtual MAC address. Corresponding computer programs and carriers therefor are also disclosed.

Embodiments of the present invention relate to methods and arrangements for configuring the L2GPs in a first STP domain connected towards a second STP domain such that L2GPs in the first STP domain are assigned with the same Pseudo Root identity. Thus the Pseudo Root identity does not have to be changed if one of the L2GPs goes down, which implies that count-to-infinity loops may be avoided. It should be noted that only one L2GP is allowed to be open towards the second STP domain. The root path costs are assigned to the L2GPs towards the pseudo root and the value of the root path cost controls which of the L2GPs that should be open. The most preferred L2GP will be given a root path cost=0, the second best L2GP will have a path cost which is high enough so the two ports never will be open at the same time if there is connectivity between the Ethernet switches having the L2GPs.

A software architecture for use in program controlled telecommunications switching exchanges in which application modules are employed to provide services to users of a particular communications application. Resource modules provide specific functional elements of communications services to the application modules by having access to and control over the exchange hardware. Network protocols provide communication between the application modules within the exchange and interfaces provide communications between the resource modules and between application modules and resource modules within the exchange.
