A first node () for determining an indication of a maximum datagram size supported without fragmentation in communication between the first node () and a second node () in an Internet Protocol, IP, network (-). The first node (): sends (), to the second node (), request messages in varying sized IP packets using an application layer protocol over UDP and which datagrams are configured not to be fragmented; receives () response messages from the second node, each indicating a received request message that the response message is in response to, was received by the second node (); identifies () a request message for which there is a change in receipt of response message compared to another request message of said varying sized IP packets; determines (), based on said identification, an indication of the maximum datagram size supported without fragmentation.

Methods and arrangements for determining indication of maximum datagram size supported without fragmentation in an IP network

A method and a network node for handling SCTP packets are disclosed. The network node provides a control instance of a control procedure for handling administrative chunks of the SCTP packets and at least one data instance of a data procedure for handling association specific chunks of the SCTP packets. With the control instance, the network node discards association specific chunks of a received SCTP packet, and processes administrative chunks of the received SCTP packet. With each of the at least one data instance, the network node discards administrative chunks and a first set of association specific chunks of the received SCTP packet, and processes a second set of association specific chunks of the received SCTP packet, wherein the second set of association specific chunks relates the respective set of said at least one association.

A transmitting entity and a method performed thereby for transmitting one or more data packets to a receiving entity is provided. The transmitting entity and the receiving entity are operable in a communication network. The method performed by the transmitting entity comprises receiving, from an application, a user layer packet, ULP, to be transmitted by means of a transport layer packet, TLP, to the receiving entity. The method further comprises bundling the received ULP together with one or more additional received ULPs in a TLP when a rate of incoming data, bytes or ULPs from the application meets a threshold; and transmitting the TLP to the receiving entity.
