Camera monitoring is an essential element in every business; whether they are for inventory scanning, worker safety, loss prevention or general security. In the past cameras used analog signals transmitted on a coax infrastructure. With advancements in image quality, scalability, management features and costs, an increasing number of camera manufactures are switching to IP based cameras.
Now, not only is the main network also taking on applications such as voice over IP, Skype, video conferencing, online radio and personal smart phones; but IP based cameras, which can be bandwidth intensive, are also put onto a company's main network. Antaira Technologies' industrial networking equipment is able to provide a more efficient architecture for applications that run on the enterprise network, such as security monitoring. Features such as multicasting with IGMP are able to improve the performance of a congested network. Other features, such as redundant rings can ensure that the edge-level of the network stays in operation even if a segment of the network is taken offline or damaged.
IGMP resides within the IPv4 internet protocol domain and is very efficient in handling multicasting traffic, such as security camera monitoring, within a network. The requirement is that the routers and switches on the network are multicast capable and the video cameras and software support multicasting. IGMP with snooping is able to build a Group Destination Address (GDA) table of destination addresses and pathways to all of the devices on a network. This is done by the IGMP Querier occasionally sending a message to all layer 2 devices, requesting what multicast units or groups of units they are connected to. This way, when layer 2 switches or routers on the network receive information with a GDA, they can either send it to the intended device or drop the information if it is not intended for any devices connected to the switch. This reduces the amount of traffic going through the switches as well as preventing other devices on the network from processing information that is not intended for them.
Whatever the application might be, big or small, improving the performance of the current networking infrastructure can be achieved by using IGMP with Snooping. Larger applications are able to achieve enhanced reliability when implementing different ring topologies within the network. Depending on the size and how the network is to be segmented, it can be beneficial to combine multiple types of rings. When multiple switches or rings are involved the effectiveness of the IGMP increases as compared to smaller networks. More switches provide more opportunities for broadcast and unicast traffic to slow the network down with unneeded flooding and retransmissions that can be prevented.
