A system and method for bandwidth management by controlling the bit rate of a signal stream in real time according to available link bandwidth. Applications include multiple-channel video data streams over a limited-bandwidth link such as a Digital Subscriber Line. A video signal is transrated at the head end to multiple streams having different bit rates, by a multirating device which sends the multiple streams over a network, along with metadata containing information about the data structure and parameters of the streams. At the network access edge, a demultirating device uses the metadata to select the stream with the highest video quality whose bit rate does not exceed the available bandwidth of the end-user's access link. This scheme provides multiple unicast signals to different end-users in place of a single multicast signal, supports multiple high-definition channels over a limited bandwidth link, and is compatible with standard encryption methods.

An Ethernet Metropolitan Area Network provides connectivity to one or more customer premises to packet-bases services, such as ATM, Frame Relay, or IP while advantageously providing a mechanism for assuring security and regulation of customer traffic. Upon receipt of each customer-generated information frame, an ingress Multi-Service Platform (MSP) tags the frame with a customer descriptor that specifically identifies the recipient customer. In practice, the MSP tags each frame by overwriting the Virtual Local Area Network (VLAN) identifier with the routing descriptor. Using the customer descriptor in each frame, a recipient Provider Edge Router (PER) or ATM switch can map the information as appropriate to direct the information to the specific customer. In addition, the customer descriptor may also include Quality of Service (QoS) allowing the recipient Provider Edge Router (PER) or ATM switch to vary the QoS level accordingly.

Example implementations relate to a networking device. For example, an implementation may receive a data processing packet identified as belonging to a processing virtual local area network. The networking device may execute an instruction associated with the data processing packet on data associated with the data processing packet and store resultant data in the payload of the data processing packet. The networking device may route the data processing packet with resultant data stored in the payload to a next device.

Disclosed are a method and apparatus for allocating SVLANs and a method and system for establishing an Ethernet service. The SVLANs allocation method of the present disclosure is applied for establishment of the Ethernet service and includes: pre-storing nodes in a transmission network bearing Ethernet service and SVLANs which have been used on the nodes; after receiving a SVLAN allocation request, automatically acquiring SVLANs which have been used on the nodes required for establishing the Ethernet service by the transmission network according to the stored nodes and SVLANs; and allocating a SVLAN which is not used by all of the nodes required for establishing the Ethernet service to the Ethernet service according to the acquisition result. The SVLANs allocation method of present disclosure can solve the problems of low efficiency of the current method for allocating the SVLANs manually and the requirement for automatic service establishment cannot be met

Techniques are described that enable MAC (L2) address authentication within an L2 switching network, such as a metro transport network. Moreover, when used in an EVPN, the techniques provide fine grain policy control over the L2 switching network so as to enable carrier networks to specify and control topologies for transporting packet-based communications. Access routers of the EVPN communicate utilizes enhanced EVPN MAC route advertisements that include an additional attribute indicating a request that L2 network address(es) being advertised be validated by a network address authentication device. A route controller relays the EVPN MAC advertisement upon validation of the L2 networks address. Moreover, the route controller may utilize the EVPN MAC route advertisements to distribute MAC-level policies to control topologies and MAC learning within the EVPN and provide services such as per-MAC traffic quota limits.

The present disclosure describes traffic forwarding in a network where a virtual local area network (VLAN) exists in multiple network sites that are geographically dispersed and connected via virtual links. A first edge device (ED) at a first site receives, from a second ED at a second site, information identifying a VLAN of the second ED through a virtual link. The VLAN identified in the information is an active VLAN of the second ED. An association between (i) the VLAN of the second ED and (ii) the virtual link through which the information is received from the second ED is recorded. When forwarding traffic to the VLAN of the second ED, it is determined the virtual link associated with the VLAN of the second ED is determined based on the recorded association and the traffic is forwarded via the determined virtual link.

Systems and methods use a fiber-based network to provide both network access services such as Internet, television, phone, and wide area networking services as well as distributed data processing services. Distributed computing nodes are provided in broadband gateways at homes and other premises in a fiber-based network to realize a distributed data center architecture. In a specific example, a provider deploys a number of broadband gateways in the homes of homeowners who agree to pay for network access (e.g., Internet, phone, television, etc.) that is received over a fiber-based (preferably point-to-point) network at the broadband gateways in the homes. Those broadband gateways also separately provide distributed workload processing. Providing both network access and distributed workload processing makes the deployment and use of the fiber-based network more economically and technically feasible.

Described is a method for joint confirmation of many messages in Low Power Wide Area Networks (LPWANs) including adding information on order of messages in transmitted data, parsing order data in messages on a receiving side, sending system message back to original transmitter where information on reception success is encoded bitwise in data field, so that each bit represents one successfully received message.

Novel tools and techniques are provided for implementing Internet of Things (IoT) functionality. In some embodiments, a computing system or IoT management node might receive sensor data from one or more IoT-capable sensors, analyze the sensor data to determine one or more actions to be taken, and identify one or more devices (e.g., household devices associated with a customer premises; vehicular components associated with a vehicle; devices disposed in, on, or along a roadway; devices disposed throughout a population area; etc.) for performing the determined one or more first actions. The computing system or IoT management node then autonomously controls each of the identified one or more devices to perform tasks based on the determined one or more first actions to be taken, thereby implementing smart environment functionality (e.g., smart home, building, or customer premises functionality, smart vehicle functionality, smart roadway functionality, smart city functionality, and so on).

Systems and methods for forming network connections are described. Embodiments of the systems and methods can include identifying a plurality of network nodes in a network system; partitioning the plurality of network nodes into a disjoint network element; identifying, based on the disjoint network element, a first virtual connection between an entry node and an exit node; assigning a first bandwidth to the first virtual connection; and forming a connection domain among the partitioned plurality of network nodes, the connection domain including the first virtual connection.
