Abstract: 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.

Abstract: A method of managing Radio Access Network (RAN) processing within a data center of a centralized radio access network (CRAN), wherein the data center comprises a plurality of compute resources that perform at least part of the RAN processing of a plurality of connected remote radio access points, includes assigning, to packets from the plurality of remote radio access points, an identification information that originates from the RAN; deciding, by schedulers based on a scheduling algorithm, on which of the compute resources processing of the packets is to take place; and using the identification information to route the packets within the data center. The compute resources are implicitly addressed through the identification information.

Abstract: A method for performing load balancing among a plurality of multipath-capable servers being provided behind a load balancer and being configured to process requests from multipath-capable clients includes contacting, by a first multipath-capable client, the load balancer for establishing an initial subflow. The method further includes selecting, by the load balancer from the plurality of multipath-capable servers, a selected server by applying a load balancing algorithm, and forwarding, by the load balancer, packets of the initial subflow to the selected server and not accepting any further subflows from the client. The method further includes announcing, by the selected server, at least one public interface to the client via the initial subflow for establishing any subsequent subflows directly between the client and the selected server.

Abstract: A method for performing centralized radio access network (CRAN) process migration, wherein the CRAN comprises a number of remote radio access points and a centralized processing center including a number of physical compute hosts that perform at least part of a radio access network functionality, includes executing a CRAN process on a first of the physical compute hosts and starting a new instance of the CRAN process on a second of the physical compute hosts; duplicating traffic destined to the CRAN process to both instances of the CRAN process; during a first time interval, processing the traffic on the first and the second physical compute host in parallel and suppressing the output of the second physical compute host; and when the second physical compute host reaches a same state with respect to the CRAN process as the first physical compute host, forwarding duplicate outputs from both instances to higher layers.

Abstract: A query message is received at a first server of a plurality of servers of a first server type, at least part of data contained in the query message is transformed to a transforming result, based on the transforming result and a first lookup table at said first server, a storage location of a respective second lookup table at one of said plurality of servers of said first type is determined, the respective second lookup table is accessed at the determined storage location of the respective second lookup table at one of said plurality of servers of said first type, and an indicator indicating a storage location of data requested by the query message is retrieved from the respective second lookup table.

Abstract: A state change in a network comprising a master server among a plurality of servers is determined, at the master server, a first lookup table is calculated, said first lookup table indicating respective partitions of a second lookup table distributed among active servers of said plurality of servers, the calculated first lookup table is distributed to each active server, and based on the first lookup table, at the master server, a modified partition of the second lookup table is generated.
