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： 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 utilisation. An arrangement suitable for executing the suggested method is also provided.
