The internal network interface is provided in each of the plurality of units, and is connected to an internal network which is established by a second address system independent from a first address system of the external network connected to the external network interface. Then, the internal network interface of each of the plurality of units conducts communication between the plurality of units using the second address system. Therefore, the internal network having no influence on the external network can be established. | 2015-04-02 |
20150092601 | Communication Apparatus - A communication apparatus may obtain a first wireless connection request from a first external apparatus, determine whether a connection number has reached an upper limit, supply first wait information to the first external apparatus in a case where it is determined that the connection number has reached the upper limit, and newly form a second wireless network which is different from a first wireless network to which both of the communication apparatus and a specific external apparatus had belonged, so as to establish a wireless connection with the first external apparatus, in a case where a wireless connection between the communication apparatus and the specific external apparatus is disconnected after the first wait information is supplied to the first external apparatus. In the first and second wireless networks, the communication apparatus may be configured to operate as a parent station. | 2015-04-02 |
20150092602 | Method and Device for Clearing Media Access Control Forwarding Entry - The present application provides a method and a device for clearing a MAC forwarding entry. The method includes: detecting, by a first RB, that a topology of a network accessed by a local terminal changes; and sending, by the first RB, a first packet to a second RB, so that the second RB clears a corresponding forwarding entry after receiving the first packet, where the second RB refers to an RB configured with at least one VLAN the same as that of the first RB. According to embodiments of the present application, after the topology of the network accessed by the local terminal changes, MAC forwarding entries of relevant devices in a whole network can be cleared in time, thereby avoiding a forwarding error. | 2015-04-02 |
20150092603 | SYSTEM AND METHOD FOR MANAGING SITE-TO-SITE VPNS OF A CLOUD MANAGED NETWORK - A management server includes a configuration and management module processing server configuration information, including a VPN peer list and VLAN/subnet settings. The management server automatically calculates the VPN configuration information, including the VPN peer subnet route information identifying which of the subnets participating in the VPN are behind which of the routers and keys to establish VPN tunnels between those routers participating in the VPN. Each of the routers participating in the VPN includes a VPN tunnel with the other routers participating in the VPN, a set of data structures storing data identifying contact information for each of the subnets participating in the VPN, a combination of an IP address and port to reach one of routers that that subnet is behind, and a forwarding module to forward traffic between the subnets. | 2015-04-02 |

20150092605 | METHODS AND APPARATUS FOR CONFIGURING A VIRTUAL NETWORK SWITCH - In one embodiment, a method includes sending a configuration signal to a virtual network switch module within a control plane of a communications network. The configuration signal is configured to define a first network rule at the virtual network switch module. The method also includes configuring a packet forwarding module such that the packet forwarding module implements a second network rule, and receiving status information from the virtual network switch module and status information from the packet forwarding module. The status information is received via the control plane. | 2015-04-02 |
