摘要： A network element (101-104) of a software-defined network is adapted to construct a configuration system on the basis of configuration data received from a controller (105, 106) of the software-defined network. The network element is arranged to transmit, in response to an event indicating a need to verify the configuration system, status information to the controller. The event may include for example a loss and a subsequent re-establishment of a connection between the network element and the controller. The status information indicates a first portion of the configuration data which has been implemented in the configuration system prior to the event. After receiving the status information, the controller is able transmit an appropriate second portion of the configuration data to the network element so as to enable verification of an appropriate portion of the configuration system. Thus, there is no need to verify the whole configuration system after the event.

摘要： The invention relates to controlling memory-usage of a functional component, e.g. a network interface of a router or a switch. A portion of a virtual memory organized to comprise virtual memory pages is reserved (201) for the use of the functional component. Mapping between the virtual memory pages and physical memory areas implemented with a physical memory is formed (202), and data items providing accesses to the physical memory areas are written (203) to one or more of the physical memory areas. The functional component is enabled to directly access to a physical memory area mapped to a virtual memory page so that the data item that provides access to this physical memory area is read (204) from the physical memory with the aid of the mapping and a virtual memory address related to the virtual memory page, and the read data item is delivered (205) to the functional component.

摘要： In a data transfer network, a network device (102) receives at its first data interface an identifier message transferred via a first data transfer path from another network device (106). The network device compares the identifier message to earlier received identifier messages. If the identifier message matches an earlier received identifier message received at another data interface and transferred via a second data transfer path from the other network device, the network device updates its forwarding database to express that the other network device is accessible also via the first data interface, and transmits address information related to the other network device via the first data interface so as to determine the first data transfer path to be an alternative for the second data transfer path. The first and second data transfer paths can be used for protecting each other and/or for load sharing.
摘要翻译：在数据传输网络中，网络设备（102）在其第一数据接口处接收经由第一数据传输路径从另一网络设备（106）传送的标识符消息。网络设备将标识符消息与先前接收到的标识符消息进行比较。如果标识符消息与在另一数据接口处接收到的并且经由第二数据传输路径从另一个网络设备传送的较早接收到的标识符消息相匹配，则网络设备更新其转发数据库以表示另一网络设备也可以经由第一数据并且经由第一数据接口发送与其他网络设备相关的地址信息，以便确定作为第二数据传输路径的备选的第一数据传输路径。第一和第二数据传输路径可以用于彼此保护和/或用于负载共享。

摘要： A network element of a software-defined network includes functional entities (321-325) capable of transferring data between each other and providing connections to other network elements. One or more of the functional entities are configurable with configuration data received from a controller of the software-defined network. The network element is adapted to transmit, to the controller, entity-specific capability descriptors related to the functional entities configurable with the configuration data. Each entity-specific capability descriptor expresses operations capable of being carried out by the respective functional entity. As the controller is made aware of the capabilities of the functional entities, the goal of the software-defined networking to provide controlled management of the data-forwarding functionality of a network element as a whole can be extended to the functional entities, e.g. line interface modules, so that each functional entity can be configured individually in accordance with the capabilities and resources of the functional entity.

摘要： A method for controlling advertising of routing data to neighbor routers is presented. A list of prefixes is maintained (301) and each prefix is associated (302) with an own indicator vector that contains a data item for each of the neighbor routers so that the data item indicates (304) whether the prefix concerned is to be advertised to the neighbor router concerned. For each neighbor router there is (303) a handling pointer pointing to the prefix that is relevant to the status of an advertising process related to this neighbor router, and the handling pointer is moved forward on the list of prefixes according as the prefixes are advertised to this neighbor router. As there is no need to maintain an own list of prefixes for each neighbor router separately, but only neighbor router-specific entries in the indicator vectors, savings can be achieved in the required memory space.
摘要翻译：提出了一种控制路由数据到邻居路由器的广告的方法。保持前缀的列表（301），并且每个前缀与包含每个相邻路由器的数据项的自己的指示符向量相关联（302），使得数据项指示（304）是否要通告所涉及的前缀到相关路由器。对于每个邻居路由器，存在（303）指向与该邻居路由器相关的广告过程的状态相关的前缀的处理指针，并且根据前缀被通告，处理指针在前缀列表上向前移动到这个邻居路由器。由于不需要分别为每个邻居路由器维护自己的前缀列表，而是仅在指示符向量中的邻居路由器特定条目，可以在所需的存储空间中实现节省。
