    • In a multi-domain network each domain, or Autonomous System (AS), has a route calculation entity (PCE A) which is responsible for computing paths between domains on behalf of clients. The route calculation entity (PCE A) sends advertisement messages to a route calculation entity (PCE B) in another domain. The advertisement message carries at least one of: inter-domain resource information and aggregated intra-domain information, such as simplified topology information or cumulative traffic engineering (TE) metrics. The inter-domain resource information can be inter-domain route or reachability information which is normally discarded by a routing protocol such as the Border Gateway Protocol (BGP) and can include inter-domain Traffic Engineering (TE) information such as reservable bandwidth.
    • 在多域网络中,每个域或自治系统(AS)具有路由计算实体(PCE A),其负责代表客户端的域之间的计算路径。 路由计算实体(PCE A)向另一个域中的路由计算实体(PCE B)发送广播消息。 广告消息中携带以下至少一种:域间资源信息和聚合域内信息,如简化拓扑信息或累积流量工程(TE)度量。 域间资源信息可以是通常由边界网关协议(BGP)等路由协议丢弃的域间路由或可达性信息,并且可以包括诸如可预留带宽之类的域间流量工程(TE)信息。

    • The present invention relates to a method in a border node of an Autonomous System (AS) and a border node comprising a border route control unit. The border node is configured to route data packets from a source node in an originating Autonomous System to a destination node in a terminating Autonomous System, possibly via intermediate autonomous systems. The method includes determining one inter autonomous system path or multiple inter AS paths constituting a route or multiple routes, respectively, between the originating autonomous system and terminating autonomous system based on at least an energy consumption metrics of transit paths through an own autonomous system and other autonomous systems and a total energy consumption metric for each possible inter autonomous system path. The border node is adapted to store the route or the multiple routes in a border gateway routing table.
    • 本发明涉及自治系统(AS)的边界节点中的方法和包括边界路径控制单元的边界节点。 边界节点被配置为可能经由中间自治系统将数据分组从始发自治系统中的源节点路由到终止自治系统中的目的地节点。 该方法包括基于至少一个通过自己的自治系统和其他的传输路径的能量消耗度量来确定构成始发自治系统和终止自治系统之间的路由或多个路由的一个自治系统路径或多个AS间路径 自治系统和每个可能的自治系统路径的总能耗指标。 边界节点适用于将路由或多条路由存储在边界网关路由表中。

    • The present invention relates to a transmitting node for transmitting data to a receiving node over at least one Ethernet link comprising a data communication unit arranged to transmit data over the at least one Ethernet link, and a control unit arranged to control the data communication unit so as to maintain the at least one Ethernet link in a link active state, characterized in that the control unit is arranged to operate in a first IDLE state in which IDLE data packets are transmitted periodically through the data communication unit over the at least one Ethernet link according to at least one predetermined IDLE data packet timing interval, and in said first IDLE state, power down at least one component comprised in the data communication unit in between the periodic transmissions of IDLE data packets. The present invention further relates to a method for use in a transmitting node, a receiving node, a network node and a system.

    • Apparatus for performing load balancing among network servers connected to an internal IPv6 network. The apparatus comprises a first interface coupled to an external IPv4 or IPv6 network for receiving packets sent across the external network and an IP packet creator coupled to said first interface. This IP packet creator is configured, for each received packet at that interface, to select a network server to be allocated to the packet or identify an already allocated network server. The IP packet creator is further configured to create a corresponding IPv6 packet for transmission over said internal network to the selected or identified network server. The apparatus further comprises a second interface coupled to said internal IPv6 network for transmitting created IPv6 packets across the internal network towards respective selected or identified network servers.
