Systems, methods and a computer program product are provided to permit the identification of all of the devices of a specified domain in a multi-domain environment. All communication among the domain devices is in-band having the advantage that no additional cabling is required. A control center between host devices and the domains receives an in-band command from an initiating device in a specified domain, the command being transmitted in response to the activation of a triggering device on the initiating device. Upon receipt of the command, the control center broadcasts an in-band command to each of the other devices in the domain directing the other devices to activate an indicator on each of the other devices. With the indicators on the devices in the specified domain activated, an administrator is able to identify those devices and thus focus his search for the faulty device only on those devices within the domain.

A frequency translating repeater (200) for use in a WLAN environment includes an in-band management link. A signal received on an antenna (300) is split to provide signal detection in a detection and control unit (385) wherein detection is performed by detectors (370, 371) filters (375, 376), converters (380, 381) and a processor (385). Delay is added using delay lines (360, 361). The in-band signal envelope may be modulated with variable gain amplifier (330) and demodulated with detectors (370, 371) to establish the management link with higher protocol layer capability. Alternatively, a modern function at least partially compliant to 802.11 modulation may be used in parallel with the frequency translating repeater.

A method for guaranteeing control traffic throughput in an in-band network configured for delivering control and data traffic, and considering both local and global views of the communication network. The method includes determining an initial configuration for forwarding first control traffic from the packet forwarding device, wherein the initial configuration comprises a first in-band queue for receiving the first control traffic that is delivered over the control path to the controller via a port in the packet forwarding device, and a first bandwidth reserved for the first queue. The method includes performing handshaking with the controller by sending a request to the controller confirming the initial configuration using a network control protocol, and receiving a response from the controller in association with the request. The method includes confirming or modifying the initial configuration based on the response.

A band control device, a band control method and a band control program for regulating specific application level traffic autonomously so that network resources can be fairly utilized. In the band control device, an application processor checks the contents of application level data to detect regulation subject data. When regulation subject data has been detected, processes such as shutdown, band limitation and delay addition is performed for L3 traffic, an L4 connection and an application level transaction with respect to the regulation subject data. Thus, specific application level traffic is autonomously regulated so that network resources can be fairly utilized.

A control facility that allows a non-programmer to use and manipulate replicated data without disrupting replication of the data itself. The control facility can be used and customized for a variety of software applications and storage platforms. These customized control facilities can enable a system administrator without application- or storage system-specific knowledge to perform off-host processing of the replicated data, such as taking snapshots of the data and running Decision Support System reports.

In response to a single user command during replication of data from a primary node to a secondary node, the following steps are performed: obtaining a control message from the primary node, wherein the control message is associated with a control command for execution on the secondary node; and automatically executing the control command on the secondary node.

The invention provides an in-band control connection establishment method and device in an SDN. The method comprises the steps that according to forwarding devices of enabled in-band controllers in the SDN, the forwarding devices periodically send two-layer SDN protocol Hello messages outwards from SDN protocol ports of the forwarding devices respectively, and a destination MAC address of each massage points to the corresponding controller; after the forwarding devices receive destination MAC addresses sent by the controllers, and the MAC addresses are the unicast two-layer SDN protocol messages of the MAC addresses of the forwarding devices, two-layer in-band ports of the controllers are recorded; after the forwarding devices receive the Hello messages with the destination MAC addresses, pointing to the controllers, from the other forwarding devices, the messages are forwarded to the controllers through the two-layer in-band ports. According to the in-band control connection establishment method and device in the SDN, the in-band control connection between the forwarding devices and the controllers is automatically established.

In a network system in which a switch forwarding packets and a control server determining route information are separated, it is desired to achieve a redundancy of the control channel by an out-of-band control channel and an in-band control channel, when the switch receives a control message regarding the flow entry registration and the like based on the route information from the control server. Specifically, the separated switch and control server are connected by a control channel for sending and receiving the control message. The switch is not only connected to a control server via an out-of-band control channel by a route dedicated to the control message, but also connected to another control server via an in-band control channel by a route which is common with a normal data communication for determining the route information, to achieve a redundancy of the control channel.

The invention relates to a method of signal transmission between a host BTS and Remote Radio Unit(s), and the BTS communication system thereof. The transmission channel between the host BTS and the Remote Radio Unit(s) uses wideband transmission links or a network, the method includes the following steps of: performing the transmission over the transmission channel using a Synchronous Digital Hierarchy (SDH)/Optical Transmission Network (OTN), forming a digital wireless signal data stream and an in-band control signaling stream transmitted over the transmission channel into a Generic Framing Procedure (GFP) frame which is further mapped to a STM-N/OTM-n frame, thereby multiplexing the digital wireless signal data stream and the in-band control signaling stream to realize SDH/OTN-based transmission. As a result, the wireless signal can be effectively transmitted between the RRH and the host BTS without specific transmission network, and the management and maintenance operation required by the signal transmission and the networking cost can be reduced.
