    摘要: A method and apparatus for hierarchical redundancy for a distributed control plane. In one embodiment of the invention, control plane processes are distributed among a plurality of processing entities including an active primary control processing entity and multiple secondary processing entities. Each of the secondary processing entities performs a dual role; an active role and a standby role. An application redundancy manager (ARM) instantiated on the active primary control processing entity manages the redundancy services for the secondary processing entities. For each secondary processing entity, the ARM selects one of the secondary processing entities to act as a backup for another one of the secondary processing entities. Upon a failure of one of the secondary processing entities, the ARM causes the secondary processing entity backing up the failed secondary processing entity to transition its standby role to an active role regarding the services provided by the failed secondary processing entity.

    摘要: A method and apparatus for a distributed control plane. In one embodiment of the invention, a primary control card distributes control plane process instances among one or more secondary cards, including a secondary control card and/or one or more Advanced Service Engine (ASE) cards. The primary control card associates particular control messages with particular control plane process instances. Upon a line card receiving a control message that is associated with a particular control plane instance, the line card forwards the control message directly to that particular control plane instance.

    摘要: A rate adaptive video conference bridge and related techniques are provided. At a video conference bridge, a source video stream is received from a source endpoint device in a network. The source video stream is encoded using a first encoder unit and second encoder unit to generate respective first and second encoded video streams. A determination is made whether to decrease or increase a bit rate of the source video stream based on network condition information. If the bit rate is to be decreased, the first encoder unit is instructed to send the first encoded video stream to a destination endpoint device. If the bit rate is to be increased, the second encoder unit is instructed to send the second encoded video stream to the destination endpoint device.

    摘要: Channel quality of an airlink is assessed at an edge router of a radio-access communication network. Based on the assessment, the cause of lost data is determined to be due to traffic congestion or due to poor channel quality. In the latter case, congestion recovery/avoidance processes of a transport protocol of over a spliced transport connection can be overridden to avoid unnecessary limitations to data flow.

    摘要: According to one embodiment, an anchor access gateway receives packets from a home agent. The packets are destined for an access terminal, and the anchor access gateway serves the access terminal. The packets are forwarded to the access terminal. The anchor access gateway receives a handoff request from a target access gateway. The handoff request requests a handover from the anchor access gateway to the target access gateway. The packets are forwarded to the target access gateway in accordance with the handoff request.
