A software-defined networking ('SDN') capable forwarding switch includes ports for receiving and/or outputting data packets and a packet pipeline including a forwarding table. The forwarding table is configured to contain a number of flow table entries ('FTEs'), that determine the forwarding switch's configuration and control behavior. The switch further includes a control engine configured to manipulate the forwarding switch's forwarding tables by adding, updating, and/or removing FTEs in the forwarding tables. An FTE of a forwarding table is configured to contain a specific action part that includes an action instruction to create a control packet and to send it to the control engine. The control packet includes embedded control instructions that cause the control engine to change the forwarding switch's configuration and/or control behavior.

Software defined network forwarding

A method for operating a home gateway that implements hybrid access with a number of interfaces to different access networks includes resolving, by a domain name service (DNS) proxy function of the home gateway, DNS resolution requests received from a client of the home gateway; and returning, by the DNS proxy function, corresponding DNS resolution responses to the client. The DNS proxy function, based on a single DNS resolution request from the client, requests a number of DNS resolutions via different interfaces of the home gateway transparently to the client.

Hybrid access DNS optimization for multi-source download

A method of managing a multipath TCP (MPTCP) connection includes establishing the MPTCP connection as a logical connection between end-points that utilizes multiple network paths with one TCP subflow per network path. At least two subflows of the MPTCP connection are terminated at different end-points.
