Embodiment Construction
[0050]First of all, when configuring the network of the intelligent community, each port of the core switch is connected to all intercom terminals within a certain communication domain through at least one intermediate switch. The communication domain is, for example, a certain building (or divided into A certain unit of a certain building, of course, can also be a property center), so that all intercom terminals of this building (including resident intercom terminals and building VTO intercom terminals) are connected to the same port of the core switch . Moreover, each port of the core switch will be configured with two VLAN IDs: one is a port-based VLAN (which can be called a small VLAN), and the value of the VLAN ID of each port of the core switch only needs to be different from each other, for example , the small VLAN ID values of each port are 11, 12, 13, 14, 15, etc.; the other is a VLAN based on an IP subnet (which can be called a large VLAN), and all ports of the cor...

The invention relates to a communication method and system for an intelligent community, a talkback terminal for an intelligent community, and a core switch for an intelligent community. The communication method for the intelligent community comprises steps that a source talkback terminal determines whether a target and the source talkback terminal are located in the same communication domain range, determines to use a first type of IP address if yes or else to use a second type of IP address, and sends data packets, wherein each talkback terminal is provided with two types of IP addresses in advance; the core switch analyzes data packets received by an intermediate switch, rejects the data packets when the first type of IP address is used or forwards the data packets to a corresponding port when the second type of IP address is used, wherein each port of the core switch is connected with all talkback terminals in the same communication domain range. The communication method and system may increase network efficiency, reduce network storms, are low in cost and easy to configure and manage.
Description
technical field [0001] The invention relates to the field of intelligent communities, in particular to a communication method and system of an intelligent community, an intercom terminal and a core switch. Background technique [0002] In the intelligent community, the terminal equipment mainly includes home video intercom equipment, unit door phone, fence machine, etc. The network protocol in the community follows the TCP / IP protocol, and the IP addresses are set on the terminal equipment respectively to realize the communication of each network in the local area network of the community. Mutual communication and security functions of residents. [0003] In order to improve network efficiency and reduce broadcast storms, the current smart community network generally uses a three-layer switch, and uses subnet masks and VLANs for network isolation. However, the problems brought about by this are: rising costs, complex configuration and management. For example, before deploym...
