An example method includes receiving, from a customer system by a cloud exchange comprising processing circuitry, a request to communicatively couple a virtual gateway on network infrastructure of the cloud exchange to a network gateway communicatively coupled to a public network, the request including data indicating a public Internet Protocol (IP) address of the customer system, wherein the customer system is configured with a first connection communicatively coupling the customer system and the public network via a network service provider (NSP) that is separate from the cloud exchange; configuring, by the cloud exchange, a network route for a network gateway to the virtual gateway, the network gateway communicatively coupled to the public network; and providing, by the cloud exchange to the network gateway, routing information including the public IP address of the customer system to create a second connection communicatively coupling the customer system and the public network.

A method, device and system for carrying out telecommunication capability group sending is provided, each node of a system for carrying out telecommunication capability group sending corresponds to a database service node, a plurality of database service nodes perform load balancing or switching on failure within themselves and each node of the system for carrying out telecommunication capability group sending may quickly read the subscription relationships and send down messages to users. The above technical solution increases the database access speed and avoids the problem of database's resources shortage and improves service performance of the telecommunication capability group sending.

Embodiments are directed towards managing persistence of network traffic using deep packet inspections of network response packets from an application server. In one embodiment, the network packets are associated with SIP messages. A traffic management device (TMD) interposed between client devices and a plurality of application servers receives messages from the client device and/or the application servers. The TMD performs a deep packet inspection to determine if a defined key value pair that includes a session identifier is detected. If so, and the message is from the application server, the session identifier is then mapped to an application server identifier to persistently refer each subsequent inbound packet from a client device having the same session identifier to the application server mapped to the session identifier.

Introduced here are network visibility appliances capable of implementing a distributed deduplication scheme by routing traffic amongst multiple instances of a deduplication program. Data traffic can be forwarded to a pool of multiple network visibility appliances that collectively ensure no duplicate copies of data packets exist in the data traffic. The network visibility appliances can route the traffic to different instances of the deduplication program so that duplicate copies of a data packet are guaranteed to arrive at the same instance of the deduplication program, regardless of which network visibility appliance(s) initially received the duplicate copies of the data packet.

A leader control plane node of a set of control plane nodes of a node cluster, may receive a request to store data in a distributed storage system including a set of access manager nodes. The leader control plane node may generate cache data identifying an instruction from the leader control plane node to one or more access manager nodes managed by the leader control plane node of the plurality of access manager nodes, the instruction instructing the one or more access manager nodes to store the data indicated in the request. The leader control plane node may then transmit a replication instruction to one or more follower control plane nodes of the plurality of control plane nodes to replicate the cache data in a respective cache of the one or more follower control plane nodes.

A non-transitory computer readable medium comprising instructions which causes performance of operations comprising: receiving, by a second network coordination device, current state information of a client device, including a transmit counter and a receive counter, from a first network coordination device, wherein the first network coordination device is a primary network coordination device for the client device and the second network coordination device is a standby coordination device for the client device; and responsive to detecting a particular event, the second network coordination device (i) transitioning to be the primary network coordination device for the client device, (ii) incrementing the transmit counter by an offset, and (iii) transmitting a message to the client device including the incremented transmit counter is shown.

The present disclosure generally relates to managing redundancy capacity in a region having a plurality of active availability zones. For individual regions, a load balancing component can implement a redundancy validation routine that includes a non-uniform distribution of load for a set of active availability zones such that one availability zone receives an increase in traffic corresponding to the likely increase that would be experienced in response to an availability zone failure. The network service can perform automatic remediation.
