摘要： The present invention relates to a method in a border node of an Autonomous System AS#n and a border node comprising a border route control unit. The border node is configured to route data packets from a source node ON in an originating Autonomous System AS#0 to a destination node TN in a terminating Autonomous System AS#T, possibly via intermediate autonomous systems. The method determines 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 ECM
BNP of transit paths through the own autonomous system and other autonomous systems and a total energy consumption metric ECM
ASROUTE 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.

摘要： 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.

摘要： The present invention relates to a method and node arrangement (110) for evaluating available conditions of a data path between a sending node and a destination node in a data communications network by means of an active measurement process comprising one or more measurement sessions. The data path and sending node comprises a sending node interface. The method involves performing a measurement session of said data path for determining a measurement result, and estimating one or more available conditions of a data path using the measurement result and one or more initial parameter values as input in a calculation algorithm. The method further comprises setting one initial parameter value for the calculation to a maximum bandwidth capacity based on the lowest bandwidth capacity value of the interfaces of both nodes sending said probe packet sequences during said measurement session.

摘要： A system, method, and node for a Routing Controller, RC, (202) to obtain from a Path Computation Element, PCE, (204) network resource path metrics (308) across a plurality of domains (320, 322) in a communication network in which each domain includes a plurality of Border Nodes, BNs (324- 338). The RC (202) sends to the PCE (204) a first message requesting a first path computation between each pair of BNs. The first message contains a maximum metric-value indicating a maximum that a path computation must not exceed for a Path Computation Client, PCC, (202) to consider the path computation acceptable Next, the RC sends a second message requesting the PCE to compute a subsequent path computation for each BN pairs for which the first path computation did not exceed the maximum metric-value. The second message contains a minimum metric-value that a path metric must exceed for the PCC to consider the path metric acceptable Next, the RC receives the computed subsequent path computation between BN pairs that exceed the minimum metric-value.

摘要： Methods and arrangements for determining a time synchronisation inaccuracy value between a first access network node 220, 222 and a second access network node 220, 222, the first access network node 220, 222 being communicatively connected to the second access network node 220, 222. A PTP (Precision Time Protocol) packet is received 400 including Node IDs representing respective transport network nodes 200, 202 along a first path,and from the second access network node 220, 222 Node IDs are obtained402 representing respective transport network nodes 200, 202 along a second path. Furthermore, a first common transport network node 202 of the first path and the second path is determined 404, by comparing received Node IDs of transport network nodes 200, 202 along the first path with obtained Node IDs of transport network nodes 200, 202 the second path. The time synchronisation inaccuracy value between the first access network node 220, 222 and the second access network node 220, 222is calculated 410, based on: the number of transport network nodes 200, 202 of non-common transport network nodes 200. The calculating 410is further based on respective time inaccuracy values of the transport network nodes200. By including Node IDs in received PTP packets before forwarding them to an access network node, the access network node is enabled to determine a first common transport network node with other access network node. Thereby, the access network node may calculate relative time inaccuracy values with respect to the other access network nodes, which may be used to decrease inaccuracy time synchronisation for co- ordination functions.
