A method for performing rate policing and re-marking in a packet switched communications network that can be used to enforce and/or monitor Class of Services (CoS) contracts including terms for single or multiple classes of service. A switching system configured as an ingress node on the network includes a network switch and rate policing and re-marking logic. The switch receives a data packet transmitted on the network, extracts information from at least one header field of the packet including a CoS parameter, a primary flow ID established for the packet, and a packet byte count, and provides the extracted information to the rate policing/re-marking logic. Next, the rate policing/re-marking logic performs flow record and token bucket processing on the primary packet flow to determine whether the packets of the primary flow conform to the bandwidth requirements specified in the CoS contract. In the event the primary flow is a sub-flow of an aggregated packet flow, the logic also performs flow record and token bucket processing on the aggregated flow to determine whether the packets of the aggregated flow comply with the terms of the CoS contract. The logic then provides the token bucket processing results to the switch.

Interconnections are managed in a mobile communications network having at least one mobile switching center (MSC) and at least one base station subsystem (BS), wherein the MSC and BS each communicate signaling messages according to a mobile signaling protocol. A first connection is provided between a first device and a second device in the network and a second connection is provided between the first device and a third device in the network. The first device includes a proxy switch for use in the network. The proxy switch includes signaling message handling logic for receiving messages from the MSC and BS in accordance with the mobile signaling protocol; message interception logic, cooperating with the signaling message handling logic, for sending an acknowledgment message to an MSC or BS that transmits a signaling message received by the signaling message handling logic and for preventing the signaling messages from being forwarded to the other of the BS and MSC respectively; message conversion logic, cooperating with the signaling message handling logic, for converting a signaling message received by the signaling message handling logic from one of the MSC and BS into a converted signaling message for transmission to the other of the BS and MSC, respectively; and message transmission logic, cooperating with signaling message handling logic, for transmitting signaling messages from one of the MSC and the BS to the other of the BS and MSC, respectively. A condition is determined to exist in the network that affects the operation of the first device. A third connection is established between the second device and the third device in the network. The network is caused to operate in a manner that is consistent with the absence of the device from the network. A first mechanism is provided that is responsive to a condition existing in the network that affects the operation of a device in the network. A second mechanism is provided that is responsive to the first mechanism and operative to electrically isolate the device from the network.

A network comprises a plurality of network devices, including a first network device coupled to a second network device and a third network in a daisy chain topology configuration. The first network device has a first device port connected to a first network port and a second device port connected to a second network port. A bypass switch is coupled to the first network device and creates a bypass path when the first network device is inoperable. The bypass switch is coupled to a processor in the first network device. The processor has a control function for closing the bypass path when the first network device is inoperable and for opening the bypass path when the first network device is operable. The bypass switch connects the first network port to the second network port when the device is inoperable.

Aspects of the invention support direct communication between a low-level device and a programmable controller over an automation bus in an industrial automation system for controlling and monitoring an industrial process. A leaf node device may include a low-level device. The leaf node device communicates directly with the programmable controller at the network layer, e.g., Internet Protocol (IP) based on an IP address contained in a signal so that the programmable controller may control the low-level device or receive status information about the low-level device. The industrial automation system may support a plurality of leaf node devices, which may be associated with different automation buses having different communication media. Signals between the programmable controller and the leaf node device may be directed with or without a switching element.
