    Abstract: A method and a system for automated switchover timer's tuning on network systems or Next Generation Emergency Systems configured so that the sending, by a master node, of a heartbeat and/or ARP ping to one or more backup nodes and/or a surveillance unit according to preconfigured switchover timer values can occur to check if the master node is still active. One or more backup nodes and/or a surveillance unit, can use an additional first Session Initiation Protocol (SIP) OPTION message to the master node after receiving the heartbeat and/or the ARP ping or if the heartbeat and/or ARP ping fails to be received according to the switchover timer values. An administrator or an administrative unit of the network can perform a switchover or failover to a backup node in case the first SIP OPTION message is not answered with a suitable response by the master node.

    Abstract: A server system for an always-on connection includes: a plurality of always-on connection processing parts; and a controller. Each of the always-on connection processing parts includes a plurality of always-on connection execution parts, and the controller is configured to execute: a receiving process to receive a first request for the always-on connection from a terminal device; a determining process to determine a target always-on connection processing part, among the always-on connection processing parts according to the first request, the target always-on connection processing part being one always-on connection processing part to establish the always-on connection with the terminal device; and a sending process to send to the terminal device a destination data indicating a destination of the second request for the always-on connection after determining the target always-on connection processing part, the destination data also indicating the target always-on connection processing part.

    Abstract: Techniques for extending network elements to inspect, extract, and complement tracing information added to L7 flows by application distributed tracing systems. The techniques may include receiving a Layer-7 (L7) message of an L7 flow associated with a distributed application and determining that the L7 message includes tracing information. In some examples, the tracing information may be mapped to a marking that is to be included in a Layer 3 (L3) or Layer-4 (L4) packet carrying the L7 message, and the L3 or L4 packet including the marking may be sent to an L3 or L4 network element. In some examples, the L3 or L4 network element may be configured to utilize the marking to determine a network decision for the L3 or L4 packet.

    Abstract: The disclosure provides an example method for live packet tracing. Some embodiments of the method include configuring a first network interface of a first pod to mark each of a plurality of packets, with a corresponding flow tag and a corresponding packet identifier, receiving, from one or more observation points, at least one of copies or metadata of the plurality of packets each marked with the corresponding flow tag and the corresponding packet identifier. In some embodiments, the method further includes displaying data indicative of the at least one of the copies or the metadata of the plurality of packets.
