摘要:
A method and system for enabling a mobile station (MS) to transfer from one Network Address Translation (NAT) domain to another NAT domain. Dynamic rules created in the first NAT domain are transferred to the second NAT domain via a first Media Policy Routing function. A tunnel is created between the second NAT domain and the first MPR for transferring a MS session. A new session from the MS is created outside the tunnel and once the MS session times out, the MS session, the states existing in the first MPR and the second NAT domain utilizing a new set of dynamic NAT rules created in the second NAT domain are all removed. The tunnel is then removed and communication via a second MPR and the second NAT domain is available.

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.

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.

The present invention relates to method and arrangements to measure connectivity between Two Way Active Measurement Protocol TWAMP entities comprising a session-server (15) and session-reflectors (16-23) in a communication network. The method comprises steps like: Dividing in the session—server (15), the session-reflectors (16-23) into at least one defined group (11-14)of session-reflectors (16-17,18-9,20-21,22-23); Transmitting a test session (1;1-4) from the session-server (15) to the session-reflectors(16-7;16-23) by using Source Specific Multicasting, said test session comprising at least one test packet (1a-1c;1a-4c) 1 being destined to at least one session-reflector (16-17;16-23) in at least one defined group (11;11-14); Replying to the at least one test packet (1a-1c;1a-4c) by the at least one session-reflector (16-17;16-23).

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.

The present invention relates to a mail server for a network. The mail server has a sender part arranged to receive outgoing e-mails from users of the network and to send the received e-mails to their recipients. The sending part is arranged to copy at least some of the contents in the received e-mail to a storage. The sending part provides an amended e-mail based on the received e-mail, said amended e-mail comprising at least one pointer substituting the contents copied to the storage, said pointer pointing at said contents in said storage.
摘要:
Method and apparatus for enabling optimisation of the utilisation of the throughput capacity of a first and a second interface of an eNB, where the first and the second interface alternate in having the lowest throughput capacity, and thereby take turns in limiting the combined data throughput over the two interfaces. In the method, data is received over the first interface and then cached in one of the higher layers of the Internet Protocol stack. The output from the cache of data to be sent over the second interface is controlled, based on the available throughput capacity of the second interface. Thereby, the alternating limiting effect of the interfaces is levelled out.
