The present disclosure discloses a method and system for partitioning WLAN in order to separate network traffic from different WLANs. Specifically, a network device receives a packet from a client connected to a first network device on an access network. The network device then determines that the received packet is associated with a VLAN that is pre-configured on the first network device based on the access network to which the client is connected. Furthermore, the network device transmits the packet to a MAC layer switching device, which is not configured with the VLAN that is pre-configured on the network device. The packet includes one of a DHCP discovery message, an ARP request message, a unicast message, a multicast message, and a broadcast message. The unicast message will be transmitted to the second network device on the pre-configured VLAN prior to being transmitted to another network device outside the pre-configured VLAN.

Embodiments are directed to secure communication over a network. If a source node sends a communication to a target node, a source gateway may forward the communication to the target node. The source gateway may provide a gateway identifier (GID) that may be associated with one or more target gateways associated with the target node. Further, the source gateway may embed marker information that includes at least a portion of the GID in the communication. If the GID is associated with more than one target gateway, a TMD selects one target gateway from the more than one target gateways. Also, the TMD provides a gateway key associated with the selected target gateway that is associated with the communication. And, the TMD may provide the communication to the selected target gateway that provides the communication to the target node.

A system establishes virtual DNS servers that are supported by a DNS server. Target IP addresses are assigned for the virtual DNS servers. Network capable devices are uniquely assigned to the virtual DNS servers for domain name resolution. Each network capable device accesses the communication network through a corresponding network device associated with a corresponding source IP address. A client's service plan is assigned to a first network capable device used by the client. The service plan is implemented through a DNS request under a session established between the first network capable device and its assigned first virtual DNS server. The session is uniquely identified by a first source IP address of a first network device used by the first network capable device to access the communication network and a first target IP address of the first virtual DNS server.

A load balancing system, a load balancing method, and a non-transitory recording medium. The load balancing system includes a first client apparatus and a second client apparatus each of which communicates with a particular server among a plurality of servers through a load balancer that distributes load of the plurality of servers. The first client apparatus transmits to the load balancer, a request to the server to acquire identification information for identifying the particular server selected by the load balancer from among the plurality of servers, notifies the second client apparatus of the identification information of the particular server, the second client apparatus requesting the load balancer to connect to the particular server, and requests the load balancer to connect to the particular server using the identification information.

A system and method can support in-memory session replication in a server cluster using a lazy deserialization approach. The server cluster can include a primary application server and a secondary application server. The primary application server operates to receive a request associated with a session from a client and maintains session information associated with the session. Based on the session information, the primary application server can responds to the client. The secondary application server operates to receive and maintain serialized session information from the primary application server. The secondary application server operates to update the serialized session information based on one or more session updates received from the primary application server. When the primary application server fails, the secondary application server can generate deserialized session information based on the updated serialized session information and responds to the client.

Embodiments of the present disclosure provide a service processing apparatus and method, and relate to the field of network service processing, and the method includes receiving, by a forwarding plane device, a packet of a first service flow, determining, by the forwarding plane device, a value-added service instance corresponding to the first service flow, and sending, by the forwarding plane device, the packet of the first service flow to the value-added service instance. In this way, a problem is resolved that a load balancer is heavily loaded because all service flow packets need to be processed using the load balancer, and generally, the load balancer may only need to allocate a value-added service instance to the first service flow packet in a service flow, thereby relieving processing pressure of the load balancer.

The present disclosure relates to a method and system for optimizing usage of network resources in the communication network. In an embodiment, a session is initiated by a user with a plurality of media servers. The usage of the network resources is optimized by a routing server which monitors session characteristics of an on-going session, user characteristics, media server characteristics and network conditions, wherein the on-going session is hosted by a plurality of session handling media servers from the plurality of media servers in the communication network. The routing server further compares the monitored data with corresponding threshold values and identifies at least one media server which violates the pre-defined threshold. The routing server further identifies one or more alternate media servers based on the media server characteristics and transfer the connectivity of one or more users to the one or more alternate media servers without disconnecting the on-going session.

The embodiments provide systems and methods for efficiently and accurately differentiating requests directed to uncacheable content from requests directed to cacheable content based on identifiers from the requests. The differentiation occurs without analysis or retrieval of the content being requested. Some embodiments hash identifiers of prior requests that resulted in uncacheable content being served in order to set indices within a bloom filter. The bloom filter then tracks prior uncacheable requests without storing each of the identifiers so that subsequent requests for uncacheable requests can be easily identified based on a hash of the request identifier and set indices of the bloom filter. Some embodiments produce a predictive model identifying uncacheable content requests by tracking various characteristics found in identifiers of prior requests that resulted in uncacheable content being served. Subsequent requests with identifiers having similar characteristics to those of the predictive model can then be differentiated.

Transferring a workload among computing devices is described. For instance, a system can comprise a first device with a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. In an example implementation, a transfer instruction receiving component can receive a transfer instruction from a second device, with the transfer instruction being generated based on a first utilization characteristic assigned to the first device and a second utilization characteristic assigned to a third device. In one or more embodiments, the first utilization characteristic can be based on a workload to provide a service to a client device served by the first device, and the second utilization characteristic can be based on measure of available workload processing capacity for the third device.
