摘要： A method of, and an arrangement for handling OAM messages received from at least one originating end-node of a communication network and having the purpose of providing information on the connectivity between a respective originating end-node and a corresponding terminating end-node is provided. The amount of OAM messages forwarded from the first intermediate node to a second intermediate node via a physical link may be limited by forwarding a received OAM message via the physical link in case a link state indicator associated with the physical link is not updated, and by responding to a received OAM message on the basis of the link state indicator without forwarding it via the physical link in case the indicator is updated. The link state indicator may be updated on the basis of the response to an intermediate OAM message, originating at the first intermediate node.

摘要： A method for performing a link aggregation on a link aggregation group, comprising a plurality of transport links, for sessions received at a first network node which is connected to a second network node via the link aggregation group. The method, which is to be executed in the first network node, enables link aggregation optimization for the sessions destined for the second network node by selectively choosing transport link for the sessions on the basis of the load of the transport links. The suggested link aggregation results in a packet load balancing and improved bandwidth utilization. An arrangement suitable for executing the suggested method is also provided.

摘要： Method and arrangement for obtaining unambiguous addressing for data packets communicated between devices (E1B, E3A) in two different local networks (A,B) using potentially overlapping private IP address spaces. A VPN tunnel is initially established between gateways (102,104) in the two local networks and an internal IP address space is defined in each network for devices in the opposite network, not overlapping with an internal IP address space used for its own devices. When the gateway (102) of one network receives a data packet from a device (E1B) in the opposite network, the packet's header is modified by changing the destination and source addresses, which belong to address spaces valid in the opposite network, into addresses belonging to address spaces valid in the present network.

摘要： Method and arrangement for communication of data packets between a first device (D1) in a first local network (A) and a second device (D2) in a second local network (B). where private IP addresses are used for devices present in the first and second local networks. A first gateway (100) of the first network updates (1:1) a local name server record (100a) with a domain name and an IP address of a second gateway (102) of the second network, each gateway having a local DNS function. When an outgoing DNS request is received (1:2) from the first device referring to a hostname of the second device, the IP address of the second gateway is determined (1:3) from the local name server record based on a domain name in the hostname. A DNS request is then sent (1:4) to the second gateway using the determined IP address, to obtain a current private IP address of the second device in a DNS response (1:5) from the second gateway. A DNS response is then forwarded (1:8) to the first device, referring to the current private IP address of the second device.

摘要： The present invention relates to methods and routing and/or switching devices for determining a path maximum transmission unit MTUP(n) size for transmission paths between edge nodes in a data communications network and for updating routing tables associated with the routing and/or switching devices in said edge nodes, which are linked together with link interfaces L(i) constituting transmission paths P(n) for data packet transmission, each link interface L(i) having a link interface maximum transmission unit MTUL(i) size. The methods involve the acquisition of a link interface maximum transmission unit MTUL(i) size for a link interface L(i), and the updating the routing table by calculating the path maximum transmission unit MTUP(n) size for each destination that involves the link interface L(i) for the acquired link interface maximum transmission unit MTUL(i) size. New link-state protocols for distributing the link interface maximum transmission unit MTUL(i) size is also provided.
