This application claims priority to Chinese Application No.: 201320350655.2 filed Jun. 17, 2013, the entire contents of which is incorporated herein by reference in its entirety.
The present invention is related to the field of communications, and more specifically to a device for storing and retrieving log files and testing circuits.
In recent years, the demand for data services is increasing rapidly, whereas the annual growth of narrowband and/or conventional voice services has been little to none. New services such as 3rd Generation (3G) mobile services, Level 2/Level 3 Virtual Private Networks (L2/L3 VPN), and Internet Protocol TeleVision (IPTV) use packet-based data traffic and utilize the bulk of most carrier and service provider bandwidth. As the demand for data services rapidly grows, providers are facing the challenge of how to lower the cost of providing these services. Carriers and service providers are searching for new transport technology that will enable them to deliver services more profitably and efficiently in a highly competitive telecommunications market.
Today, many carriers must operate and maintain multiple networks or different layers of the network. With data traffic consuming the majority of carrier bandwidth in the current Synchronous Digital Hierarchy/Synchronous Optical NETwork (SDH/SONET) infrastructure, it is critical for today's carriers and service providers to use a convergence transport technology. One of the main objectives of the next generation transport network is the ability to multiplex and aggregate multiple services over the same physical facility or infrastructure. This ability enables a provider to provision new services on the existing facility without upgrading the physical installation for every new service. One of the technologies used in modern Packet Transport Network (PTN) technology takes advantage of the cost-effectiveness and ease-of-use of Pseudo Wire (PW) over Transport MultiProtocol Label Switching/MultiProtocol Label Switching Transport Profile (T-MPLS/MPLS-TP) architecture RFC 3985, and adds carrier-class features such as traffic engineering, Quality of Service (QoS) and connection oriented provisioning. The introduction of T-MPLS/MPLS-TP Pseudo Wire (PW) based PTN to metro transport networks permits network operators to migrate all of their transport services to be carried over converged IP/T-MPLS/MPLS-TP core networks. This approach allows carriers and service providers to generate more revenue by rapidly introducing new, as well as existing services, while reducing operational and capital network costs.
At present, the operation logs of existing equipment are stored in two ways. A first method is to store the logs on the Dynamic Random Access Memory (DRAM) within the equipment. Generally though, the equipment has limited memory space and will lose the stored logs after power interruption. Another method is to print and store the logs by using an external Personal Computer (PC) terminal, which needs additional installation space and power supply.
To manage network and data services better, both manufactures and telecommunications (“telecom”) operators are looking to use special external devices to store and maintain more logs for longer periods of time, while requiring the special external devices to have a low power consumption, a large memory and be easy to maintain.
The present disclosure relates to resolve the technical problem related to the current testing requirements that are complicated and require a separate connection to the test equipment. The present disclosure relates to an external device for storing log files, retrieving the log files and testing the circuits. The present disclosure provides network connection diagnosis and daily management and maintenance for the equipment.
The device for storing and retrieving log files and testing circuits is installed in a transceiver Small Form-factor Pluggable (SFP) interface of the data transport network product. One end of the device can connect to the SFP interface to be supplied power and connect to the network in order to remotely communicate with the management equipment. Another end of the device uses a Registered Jack (RJ)-45 connector to provide two Recommended Standard (RS) 232 serial interfaces, which connect with serial ports of the equipment. The output logs of the equipment can be stored in the device and remote management equipment can access the device via a TELephone NETwork (telnet), Internet, or other network interconnection scheme.
The device for storing and retrieving log files and testing circuits is designed to remotely store and retrieve logs of the equipment and test the circuits. The device for storing and retrieving log files and testing circuits includes a Control and Management Module used to control the operation of the embedded operating system in the device, so that the module can store the logs from the output serial port of the equipment and establish the file system. The Control and Management Module supports a File Transfer Protocol (FTP) server function, ping function (as a client) and telnet sever function; other functions are contemplated.
The device for storing and retrieving log files and testing circuits further includes a Network Interface Module having one end connected to the Control and Management Module, and another end connected to the transceiver SFP interface of the data transport network to supply power and achieve a network connection.
The device for storing and retrieving log files and testing circuits further includes a Serial Interface Module to connect the Control and Management Module with a serial port of the equipment, and is used for receiving the logs from the output serial port of the equipment.
The Control and Management Module also includes a storage unit, which is used for the real-time storing of the logs from the serial port of the equipment.
The Control and Management Module, Network Interface Module and Serial Interface Module are encapsulated in a transceiver SFP electrical module.
The Control and Management Module includes a micro Central Processing Unit (CPU) or processor to provide overall control for the device. The storage unit of the Control and Management Module includes a built-in memory card. The Control and Management Module includes a Media Access Control (MAC) unit.
The Network Interface Module includes a first PHYsical layer interface device (PHY1) and a second PHYsical layer interface device (PHY2). One end of PHY1 connects the MAC unit through a Reduced Media Independent Interface (RMII) and the other end connects to one end of the PHY2 through a 100 BASE-TX interface. The other end of the PHY2 is a Serial Gigabit Media Independent Interface (SGMII), used to connect with the transceiver SFP interfaces of the data transport network.
The device includes a Power Module, which provides the power supply for the device through the SFP interface of the data transport network.
In addition, the Serial Interface Module connects to a serial port of the equipment by using a cable. The device has a RJ-45 connector for cable connection, which provides two RS232 serial interfaces.
The device for storing and retrieving log files and testing circuits is of similar size with a standard SFP electrical module, which is convenient to carry and install. When installed in the SFP interface of the data transport network product, the device can power up and work automatically, which avoids the need for taking additional power from the equipment room and saves on installation space.
The present disclosure will become more readily apparent from the specific description accompanied by the following drawings, in which:

The application embodiment of the device 100 is shown in
The devices M1-M5 record the logs from the serial port of the equipment 210a/210b to store in respective eMMC cards automatically. The remote management equipment PC can retrieve the operation logs of the four NEs (NE1, NE2, NE3 and NE4) through the center NE NE5.
The procedures using the device 100 to read the operation logs of the equipment 210a/210b will now be described. If a user needs to download the log files of NE1 and the Internet protocol (IP) address of the device 100 installed in NE1 (i.e. M1) is for example set to 192.168.10.225, the following steps are performed.
In step 1 a local directory is created on the remote PC for NE1 to store corresponding log files: e.g. d:\NE1_log. In step 2 a command window is opened to enter an ftp command: e.g. ftp 192.168.10.225. In step 3, a username and password can be required to be entered to access the device 100: e.g. User <192.168.10.225>/Password: admin. In step 4 a command can be entered to show the folders of the device 100: e.g. ftp>Is. In turn, the folders are displayed (4 in this example): Directory_A_1; Directory_A_2; Directory_B_1; Directory_B_2. In step 5 the required directory is specified as the current directory to retrieve the log files from \Directory_A_1: e.g. ftp>cd Directory_A_1. In step 6, the log file names in \Directory_A_1 can be displayed: e.g. ftp>Is. In turn, all the log files in Directory_A_1 are displayed: e.g. LOG_1.TXT; LOG_2.TXT; LOG_3.TXT; LOG_4.TXT. In step 7 a specific directory can be specified as the local directory: e.g. ftp>Icd d:\NE1_log. In step 8 log files from Directory_A_1 can be downloaded to the directory: d:\NE1_log: e.g. ftp>mget *.TXT.
The procedures using the device 100 to test the circuits of a data transport network 200 will now be described. In this example, it is presumed that the user has configured the circuit from NE5\Slot5\Port3 to NE1\Slot5\Port2. In order to check whether the circuit configuration is successful, the traditional method is to test the configuration by connecting data communication test equipment (e.g. Smart BITS) to each port. In the present disclosure, device 100 is inserted into NE1\Slot5\Port2 to test the configuration. If the IP address of the device 100 is 192.168.10.225, the following steps are performed.
In step 11, on the PC, select [Start>run]. In step 12, enter <cmd> and click <OK>. In step 13, the command window is displayed. In step 14 “ping 192.168.10.225” in entered. In step 15 the Enter key is pressed to check whether the connection is successful. In step 16, the following may be returned:
If the test passes, the service configuration is successful.
