When a signal-to-noise ratio affecting radio communication becomes sufficiently low, then the data transmission rate is responsively decreased in compensation. The signal-to-noise ratio of the communication link is thereby increased. Data for multiple different services is transmitted in data packets between two radios. By allocating one part, or time slot, of the data packet's payload to one service, and allocating another part, or time slot, of the data packet's payload to another service, communications sessions for multiple services can be maintained concurrently. Services are prioritized relative to each other. In case the signal-to-noise ratio becomes too low, data packet portions that are related to lower-priority services can be omitted from some data packets before those data packets are transmitted. Data remaining in the packet can be sent at a reduced data transmission rate without causing the quality of service for the remaining packets to fall below the minimum required level.

A method for dynamic load balancing using different data transmission paths in a telecommunications network includes: in a first step, communication data are exchanged between a fixed network part and a first router device using a first, wireline interface as the data transmission path; and in a second step, further communication data are exchanged using an alternative data transmission path, either in addition to using the data transmission path or instead of using the data transmission path, between the fixed network part and the first router device—via the second router device.

Some embodiments of the invention provide a method for implementing a logical switching element that includes multiple logical ports through which the logical switching element receives and sends data packets. The method configures multiple managed forwarding elements to implement the logical switching element. The method also determines that port isolation has been enabled for the logical switching element. The method further provides a set of data directing the managed forwarding elements to drop a particular data packet received through a first logical port when the particular data packet is addressed to a second logical port different than the first logical port to implement the port isolation.

Access point management is described. In an implementation, a method includes selecting one of a plurality of clients, in which each of the clients has a client profile which describes the client's experience with one or more of a plurality of access points. The selecting is performed based on one or more of the client profiles. A determination is made as to whether at least one of the access points utilized by the selected client should be replaced by another one of the access points. The determination includes establishing whether a difference between a connectivity score for the at least one access point and a connectivity score for the other access point exceeds an inertia value.

According to an example, in a method for redirecting virtual machine traffic a virtual switch may be implemented in a physical server. In addition, a packet sent from a first virtual machine to a second virtual machine may be detected, in which the first virtual machine and the second virtual machine are in the same virtual local area network (VLAN), and in which the packet has a first VLAN label that identifies the VLAN. Moreover, the first VLAN label may be replaced with a second VLAN label in the packet, in which the second VLAN label differs from the first VLAN label, and the packet may be sent to an uplink switch, in which the uplink switch may send the packet to a network security module.

A network device provides, to a user device, a user interface to configure preferences for a bandwidth boosting service. The bandwidth boosting service is configured to supplement a subscriber's primary content delivery connection with additional bandwidth from a broadband cellular connection. The network device receives, via the user interface, user configuration preferences for the bandwidth boosting service and provides, to a boosting router at a local subscriber network, configuration settings that are based on the configuration preferences. The network device receives, from the boosting router, a boost request for content delivery to a user device at the local subscriber network and generates, in response to the boost request, a split-path instruction for the content delivery to the local subscriber network via a primary data path and a supplemental data path.

A data packet forwarding method including receiving, by a network node, a data packet that comprises a bit string, a BFIR identifier (ID), and a multicast replication path (MRP) ID, wherein the BFIR ID identifies an ingress network node for a multicast group, and wherein the MRP ID identifies the multicast group, identifying an entry in a BIER Replication Path Cache Table (BRCT) using the BFIR ID and the MRP ID, wherein the entry identifies a replication neighbor (NBR) list associated with the BFIR ID and the MRP ID, and forwarding the data packet in accordance with the replication NBR list.
