摘要： A network element (“NE”) is capable of starting an automatic configuration in response to an initiator such as a dongle. In one embodiment, after resetting a counter used for identifying a signal, a process for the automatic configuration forces a first test signal at a test mode output (“TMO”) pin of a console interface to a logic state zero. Upon detecting a break condition at a receiver pin, a second test signal at the TMO pin is forced to a logic state one. When logic state one is detected at the receiver pin of the NE, an automatic configuration mode at the NE is activated.

摘要： A method and/or network system is able to perform an in-service software upgrade (“ISSU”) using virtualization technology while ongoing network service is maintained. After receipt of an upgrade signal such as a command of software upgrade, a new or second virtual machine (“VM”) is created in response to the upgrade signal. After downloading the new version of program to the second VM while maintaining the first version of program running on the first VM, the process for providing network management begins to migrate from the first version of program to the new version of program. The process simultaneously facilitates ISSU for a data-path module such as a line card to convert from the previous version of software to the new version of the software.

摘要： A communication network configured to substitute serving gateway (“SGW”), packet data network gateway (“PGW”), and mobility management entity (“MME”) with an OpenFlow network controller (“OFNC”) for packets routing between mobile devices and the Internet is disclosed. The network includes a cellular base station, a packet data network (“PDN”), and OFNC. The cellular base station provides wireless communication for user equipments (“UEs”). The PDN is able to route packet flows to their destination(s). The routing controller or OFNC manages a cluster of routers including at least one edge router via OpenFlow protocol. The OFNC, in one embodiment, establishes a routing path between the cellular base station and the PDN for an authenticated UE via a group of routers based on information obtained from an authenticating server and a charging system.

摘要： A mobile network configuration is able to offload packet flows based on identification (“ID”) rules to a wireless network using a deep packet inspection (“DPI”) function. After activating DPI function located in a packet data network gateway (“PDN-GW”), every packet flow passing through the PDN-GW is monitored, detected, and analyzed based on a set of predefined ID rules. Upon identifying a packet flow for a predefined network application, the packet flow is offloaded from a long term evolution (“LTE”) network to a wireless local area network (“WLAN”) or Wi-Fi network. To reduce traffic loading on the LTE network, the PDN-GW sends binding updates containing offloading information associated with the packet flow to user equipment (“UE”) for offloading implementation.

摘要： A method or corresponding apparatus is employed for distributing media on a ring network. Multiple nodes and communications links are configured to distribute media in the ring network. Distribution of the media is disabled on a communications link between a selected pair of adjacent nodes in the ring network in a manner maintaining communications between the selected pair of adjacent nodes other than for distribution of the media. This configuration results in a “horseshoe” topology of the ring network with respect to the media, where distribution of the media on the ring network occurs in one or two downstream directions from head-end ingress node(s) on the ring network. Virtual Private LAN Service (VPLS) may be employed to transport the media. In an event of a link or node failure, the disabled link is enabled, allowing for continued distribution of the media with network recovery in a timeframe typically unobservable by an end user.

摘要： An apparatus and method for transferring information in bulk between network devices employing File Transfer Protocol (“FTP”) are disclosed. During a network discovery process, an Element Management System (“EMS”) initiates a file generation command formatted with Simple Network Management Protocol (“SNMP”) to one or more network element (“NE”). After obtaining configuration information from one or more network devices, an NE, in one embodiment, establishes a file containing the configuration information and subsequently stores the file in a storage location. The file formatted in SNMP format is forwarded to EMS suing FTP/SFTP (secure file transfer protocol)/TFTP (trivial file transport protocol).

摘要： A reconfigurable optical add drop multiplexer (ROADM) includes local interfaces at which optical signals of different wavelengths are locally input into the ROADM, and a network interface configured to connect the ROADM to a network from which multiplexed optical signals of different wavelengths are transmitted to the network. In a first configuration, the ROADM is configured to transmit from the network interface to the network multiplexed signals of different wavelengths having a first minimum frequency difference. In a second configuration, the ROADM is configured to transmit from the network interface to the network multiplexed signals of different wavelengths having a second minimum frequency difference. The second minimum frequency difference is greater than the first minimum frequency difference. This arrangement reduces the power of four wave mixing cross products produced when optical signals of three wavelengths are multiplexed and transmitted from the ROADM to NZDSF or DSF fiber types.
