Abstract: There is provided a method performed by an entity for handling execution of functions in a function-as-a-service (FaaS) system. The FaaS system includes one or more nodes on which functions are executable. The method includes grouping functions into a group of functions to be executed on a single one of the one or more nodes. The grouping is based on information from the one or more nodes. The information is indicative of which functions access which data during execution of the functions and each function of the group accesses the same data as at least one other function of the group.

Abstract: A node (120) receives data packets. For each of the received data packets, the node (120) extracts a first value from the data packet. The first value indicates a delay requirement of the data packet. For each of the received data packets, the node (120) also extracts a second value from the data packet. The second value indicates a level of importance assigned to the data packet. Depending on the first values and the second values, the node (120) controls forwarding of the received data packets.

Abstract: A method and a transmitting node for redirecting of a flow of data packets to a path of alternative paths, and a method and a receiving node for enabling redirection of a flow of data packets to a path of alternative paths, where data packets are marked with a value indicating the importance of the data packets. The method for directing directs one or more flows of data packets for the alternative paths, wherein data packets marked with a higher value are prioritized over data packets marked with a lower value. Based on feedback information, the transmitting node redirects a flow of data packets to a second path of the alternative paths, if the metric of congestion indicates a higher congestion on the first path than on the second path.

Abstract: Embodiments herein relate to a method in a first communication node (10?) for transmitting a packet in a first packet network operated by a first network operator towards a destination node (10?,12). The first communication node (10?) is comprised in the first packet network. The first communication node (10?) receives a packet with a first value related to resource sharing in a second packet network operated by a second network operator, wherein the first value indicates a level of importance of the packet relative importance of another packet along a scale of the second packet network. The first communication node (10?) remarks the packet with a second value related to resource sharing in the first packet network, wherein the second value indicates a level of importance of the packet relative importance of another packet along a scale of the first packet network. The first communication node (10?) transmits, over the first packet network, the remarked packet towards the destination node (10?,12).

Abstract: A method is provided by a network element to execute a forwarding information base (FIB) manager to program a packet forwarding function of the network element. The FIB manager supports a hybrid control plane with software defined networking (SDN) and local control plane processes. The method includes receiving a request to configure a node reachability configuration element, where the node reachability element describes packet processing instruction for the packet forwarding function to forward packets toward a referred node, selecting a flow control agent to be updated for reachability to the referred node, and updating a logical forwarding information representation to encode a next hop identifier for the referred node.

Abstract: A method, femto Base Station, and network service node for connecting a User Equipment UE, to local devices in a local network. The femtoBS includes a femtoBS part and a Packet Data Network Gateway, PDN-GW, part comprising a subset of PDN-GW functions. The UE sends a PDN connection request that includes a special Access Point Name, APN, which indicates the request ts for local IP access. The network service node, such as a Mobility Management Entity, MME1 includes a gateway selection mechanism that, based on the special APN1 selects the PDN GW part of the femtoBS device to serve the connection. A route optimization function in the femtoBS shortcuts the traffic between the femtoBS part and the PDN GW part, providing direct access to the local network. The UE may access the Internet through a residential gateway in the local network and a fixed access connection.

Abstract: One aspect provides a method of enabling a user entity, UE (10), to access a local Packet Data Network, PDN, when the UE (10) accesses an Evolved Packet Core, EPC, network via a Broadband Forum, BBF-defined access network over the S2a interface. The method includes receiving a request from the UE in the EPC (203, 204), the request including one or more Access Point Names, APNs. A decision (205) is made to offload at least one of the APNs by designating it as a local APN. Communications are established between the UE and a PDN identified by use of the designated local APN in a session set-up request from the UE. The communications are established directly (505), via the BBF-defined access network, and so as to avoid passing data packets via the EPC. Other aspects include an EPC network entity, a Broadband Network Gateway, BNG (22), in a BBF-defined access network (20), and User equipment (10) configured in accordance with the method.

Abstract: There is described a method and apparatus for sending data through one or more packet data networks. A stripped-down packet is sent from a packet sending node towards a cache node, the stripped down packet including in its payload a pointer to a payload data segment stored in a file at the cache node. When the stripped-down packet is received at the cache node, the pointer is used to identify the payload data segment from data stored at the cache node. The payload data segment is inserted into the stripped-down packet in place of the pointer so as to generate a full size packet, which is sent from the cache node towards a client.

Abstract: A method in a communication node for handling a packet to a destination node in a communications network, and associated nodes. The communication node associates the packet with a remaining value, with the remaining value being a packet value reduced by a threshold value of an outgoing link from the communication node towards the destination node. The threshold value corresponds to a congestion level of the outgoing link. The communication node further handles the packet based on the remaining value, the handling including determining whether to drop or to transmit the packet along the outgoing link based on the remaining value.
