Techniques are provided for passive management of network connections. In an example, a cluster node determines to migrate its client connections to other nodes of its cluster. The cluster node can determine whether a client implements an always resolving policy (regarding resolving a domain name of the cluster), a cache resolving policy, or a resolve once policy. Where the node disconnects a client and it does not reconnect (because a domain name service (DNS) server no longer resolves a domain name to the node), the client implements an always resolving policy. Where the node eventually stops reconnecting, the client implements a cache resolving policy. After nodes of those types are migrated, nodes that implement a resolve once policy. The node can migrate these clients by disconnecting them in coordinating with stopping accepting connections. This can lead to non-disruptive migration of all clients.

In some embodiments, a method detects a state of a first session between a first workload and a second workload. The first workload and the second workload send packets in the first session via a first path to maintain a state of the first session. When the state of the first session indicates the first workload is down, the method receives information for network metrics of network traffic being sent in the first path. The method determines when the second workload should transition from a standby mode to an active mode to take over as an active workload in an active/standby configuration between the first workload and the second workload based on the information for the network metrics.

This disclosure describes, in part, techniques for increasing persistent connection scalability. For instance, a server may establish persistent connections with sources. The server may then determine, based on the types of persistent connections, an amount of at least one resource in use. For example, the server may determine that a first type of connection, such as an idle connection, uses a first amount of the resource(s) and a second type of connection, such as an active connection, uses a second amount of the resource(s). The server may then determine if the amount of the at least one resource in use satisfies one or more thresholds. If the amount of the at least one resource in use satisfies the one or more thresholds, the server may perform one or more actions. For example, the server may cease establishing new persistent connections, migrate the first type of connections, and/or migrate the second type of connections.

Embodiments of the present application provide a method, device and system for controlling an air interface resource and relates to the field of communications, which improves air interface resource utilization. The method includes: when a core network device or user equipment detects that service data is not transmitted over a communication channel between the two devices by using an air interface resource, switching a first frequency of sending a hello packet to a peer device to a second frequency, and sending a frequency switching message to instruct the peer device also to switch the first frequency of sending a hello packet to the second frequency, so that when the hello packet is not detected within a packet detection period, an access network device releases an air interface resource occupied by a first communication channel.

A method is provided to detect a lost packet in an event-based communication system which uses a communication protocol without error correction or recovery. The method includes maintaining a plurality of counters for tracking an overall count of data packets transmitted, and a count of data packets transmitted for each event-type; and transmitting a sequence of data packets to at least one remote device. Each data packet includes information of an event-type from the plurality of different event-types and count information associated with the counters. The method further involves receiving a message from the at least one remote device that at least one data packet from the sequence of transmitted data packets is lost based on the count information from at least one transmitted data packet; and taking at least one action in response to the message.
