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 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.

Scheduler-managed routing of information in cloud-ran data centers

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.
