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： In one implementation, a method for managing access to mobile endpoints leverages the always-on nature of a first internet layer protocol to expand the reach of a second internet layer protocol. A network device receives a request originating from a remote host. The request includes a domain name of a mobile endpoint. The network device queries a database using the domain name for a first address of the mobile endpoint as designated according to the first internet layer protocol. The network device transmits a wake up message to the mobile endpoint using the first address. A data bearer for communication with the second internet layer protocol is established based on the wake up message, and a second address is assigned to the mobile endpoint. The second address is forwarded to the remote host, allowing communication between the remote host and the mobile endpoint.

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 system may provide connectivity service in a multi-tenant network. A first node in the multi-tenant network can receive data packets, each of the data packets identifying one of a plurality of tenant devices. The first node can determine an Internet Protocol (IP) address associated with each of the data packets. The first node can determine a Virtual Local Area Network Identifier (VLAN ID) based on the IP address, the VLAN ID being a unique identifier of a respective one of the tenants. The first node can add the VLAN ID of a corresponding one of the tenants into a header of each of the data packets. The first node can transport the data packets to a second node in the multi-tenant network via a multi-tenant network tunnel protocol.

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, providing network redundancy includes configuring a session registrant database to have one or more virtual standby states. Each virtual standby state corresponds to an active router. The session registrant database receives session information from the active router(s) and determines that an active router has failed. A virtual standby state corresponding to the failed router is set to a virtual active state. A second router is configured to have a standby state associated with the set virtual active state. The session information received from the failed router is transferred to the second router, and the second router is configured to have an active state.

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.
