Example aspects include techniques for implementing a transparent TCP proxy for containerized applications. These techniques may include receiving an outgoing packet from the containerized application via a container bridge and determining, based on a connection associated with the outgoing packet, whether the outgoing packet corresponds to an incoming packet identified by a first marking as being redirected through the TCP proxy. In addition, the techniques may include in response to determining that the outgoing packet corresponds to the incoming packet, adding a second marking to the outgoing packet to indicate that the outgoing packet is to be routed through the TCP proxy, sending the outgoing packet to the TCP proxy based on the second marking, and transmitting an outgoing processed packet to an external device having the destination address, the outgoing processed packet resulting from a performance of a proxy operation by the TCP proxy on the outgoing packet.

An electronic eyewear device communicates with a backend service system via a device hub that provides an edge proxy server for a service request from the electronic eyewear device to the backend service system. The device hub provides a standardized request/response optimized schema for providing a standardized communication between the electronic eyewear device and the backend service system in response to the service request in a standardized format adapted to minimize network requests. A standardized communication is provided to at least one backend service of the backend service system, and a standardized response to the standardized service request is received from the backend service(s) and provided to the electronic eyewear device. In one configuration, the device hub may issue asynchronous requests to backend services in response to a service request from the electronic eyewear device and merge responses into a standardized response for the electronic eyewear device.

A content delivery network (CDN) is enhanced to enable mobile network operators (MNOs) to provide their mobile device users with a content prediction and pre-fetching service. Preferably, the CDN enables the service by providing infrastructure support comprising a client application, and a distributed predictive pre-fetching function. The client application executes in the user's mobile device and enables the device user to subscribe to content (e.g., video) from different websites, and to input viewing preferences for such content (e.g.: “Sports: MLB: Boston Red Sox”). This user subscription and preference information is sent to the predictive pre-fetching support function that is preferably implemented within or across CDN server clusters. A preferred implementation uses a centralized back-end infrastructure, together with front-end servers positioned in association with the edge server regions located nearby the mobile core network. The predictive pre-fetch service operates on the user's behalf in accordance with the user preference information.

In one embodiment, a method is performed. A device may include an interface in communication with a network. The device may determine whether an all-active multi-homed ethernet segment (ES) associated with the interface is enabled. On a condition that an all-active multi-homed ES is enabled, the device may determine an ethernet virtual private network (EVPN) designated forwarder (DF) state of the all-active multi-homed ES. If the all-active multi-homed ES is enabled and has an ethernet virtual private network (EVPN) designated forwarder (DF) state, the device may enter a protocol independent multicast (PIM) designated router (DR) state. If an all-active multi-homed ES is enabled and does not have an EVPN DF state, the device may enter a PIM non-DR state.

Methods and systems for establishing a media streaming connection between a client and a placeshifting device that are each communicating via a network using a standard and nonstandard port, including: in response to an initial denial of a request to receive streamed content by a client via a nonstandard port in communication with the placeshifting device, attempting another request by the client using a standard port in communication with a relay reverse proxy service of a relay backend server to the placeshifting device; establishing a first connection by the client between the relay reverse proxy service of the relay backend server and the client using the standard port to receive streamed content from the placeshifting device; and establishing a second connection between the relay reverse proxy service of the relay backend server and the placeshifting device using the nonstandard port to communicate streamed content streamed directly from the placeshifting device.

Resource utilization in edge-computing clusters and other computing clusters can be improved according to some aspects described herein. For example, an event handler can detect an event involving a state change to a data object. In response to detecting the event, the event handler can access an event registry storing relationships between a group of controllers and a group of events that are to be handled by the group of controllers. The event handler can determine, using the event registry, a controller that is configured to handle the event. The event handler can then transmit a command over a network to a computing cluster that includes a reconciler associated with the controller, where the command is for causing the reconciler to perform a reconciliation operation with respect to the data object. Separating the event-handling logic from the reconciliation logic in this way may improve resource utilization.
