Services can be isolated across a single physical network interface. A gateway that is installed at the user's premises can include a single inbound port over which multiple services can be provided to the premises. The gateway can evaluate all outbound frames that are received at the port to identify to which service they pertain and then tag the frames with an identifier assigned to the service. This tagging will enable the frames to be delivered to the intended service provider. When the gateway receives an inbound frame, it can strip the identifier from the frame and forward it over the single inbound port regardless of the service to which it pertains. In this way, multiple services that are provided to the user's premises can remain isolated on the wide area network even though they are provided over the same physical medium on the user's local area network.

The present general inventive concept relates to systems and method for routing electronic messages depending on message content.

Embodiments provide a method and a device for processing network uplink and downlink data, where the method includes a central node device and a remote node device. The central node device is an edge device of a backbone network, and the remote node device is an edge device of a user network. The method includes: performing, by the central node device, downlink digital signal processing on a first data frame received from a network side to obtain a downlink to-be-sent data frame, and sending, the downlink to-be-sent data frame to the remote node device.

A communication device for forming a communication network, which generates a search frame, which is a frame for searching for a communication path in setting a communication path to/from another communication device, transmits the search frame to other communication devices, and selects a communication path with a shortest delay time to each of the other communication devices on the basis of information in the search frame having passed through other communication devices and returned to the communication device.

A method for processing data packets in a communication network includes establishing a path for a flow of the data packets through the communication network. At a node along the path having a plurality of aggregated ports, a port is selected from among the plurality to serve as part of the path. A label is chosen responsively to the selected port. The label is attached to the data packets in the flow at a point on the path upstream from the node. Upon receiving the data packets at the node, the data packets are switched through the selected port responsively to the label.

A method of providing information regarding an Ethernet frame, within the Ethernet preamble of the Ethernet frame, comprises inserting into the Ethernet preamble an inter-line-card header that includes a start control character, a version number, a parity bit, a source port, a destination port, and a forwarding domain entry; and preserving said inter-line-card header, inside of said Ethernet preamble, in a Media Access Control (MAC) sub-layer in said Ethernet frame. The method may include a step of selecting the decoding format for the inter-line-card header corresponding to the version number and/or forwarding other Ethernet frames according to additional forwarding information provided by the forwarding domain entry. The inter-line-card header may be preserved in the MAC sub-layer by keeping the Ethernet preamble at the beginning of an Ethernet frame received over an Ethernet backplane, and passing the combined preamble and associated Ethernet frame to an inter-line-card header processing module.

A device for connecting base station(s) to a cellular label switched network in a cellular network. The cellular network includes: base station(s), the connecting device(s); cellular label switched network(s); and service area(s). The base station(s) communicates with mobile terminals using wireless technology. The wireless technology uses a protocol layer architecture that includes at least one of the following: a wireless physical layer; a wireless medium access control protocol layer; a radio link control layer; and a network layer. The connecting device(s) include: a first interface to connect to the base station(s); a second interface to connect to cellular label switched network(s); and a label forwarding layer that: forwards packets between base station(s) and cellular label switched network(s); attaches label(s) to packets and removes label(s) from packets. A service area divided into a multitude of cells through which mobile terminals can move through and communicate with base station(s).

Technologies for managing network traffic through heterogeneous fog network segments of a fog network include a fog node deployed in a fog network segment. The fog node is configured to receive a fog frame that includes control instructions. The fog node is further configured to perform a route selection action to identify a preferred target fog node based on the control instructions, perform action(s) based on the control instructions and network characteristic(s) of the fog network segment relative to corresponding network characteristic(s) of the different fog network segment, and generate updated control instructions based on at least one network characteristic of the different fog network segment. Additionally, the fog node is configured to replace the original control instructions of the received fog frame with the updated control instructions and transmit the received fog frame with the updated control instructions to the preferred target fog node. Other embodiments are described and claimed.
