Communication and network software establishes and manages the digital communication networks. These may include LAN, WAN, wireless communication systems, email, and Audio and video networks. Communication and network software is designed to work with hardware that is compliant with specific standards for digital communication. It also allows the networks to transmit audio/ video or other information in the packet forms over modems and telephone lines. Voice communication, network security, network utility, and network monitoring software are the part or the services of communication and network software.

Network Security and utility Software

Network security software deploys key encryption and firewall monitors to the networks. Its other features include security patch management, user and group authentication, control over portable storage, and the permitting or none permitting to share information. Network utility software is for administrator assistance. It can be used to bridge gap among heterogeneous networks. It offers file processing and handling, and scripting capabilities. Network utility software supports web based input / output metrics measurements or architecture-neutral applications such as java.

Voice Communication Software

Voice Communication software makes sure the real time transmission of voice over IP (internet Protocol). The hardware used in VOIP is complaint with IEEE (Institute of Electrical and Electronics Engineers) 802.11e standards. It monitors and also if required enhances the voice clarity.

Network Management Software

Network management software manages the assets of a network. These assets may include Switches, routers, gateways, hubs, servers, repeaters, and PDC / SDC controllers. The software uses the available information database and utilizes it into a diagram network tom monitor bandwidth.

Network Monitoring Software

Network monitoring software monitors (stores and controls) the network's statistical information. The information concerns to the network protocols, packet transmission through firewalls and gateways, and traffic performance over ports, routers, and bridges. Network monitoring software offers java based GUI (graphical user interface) and command line functions in open source operating systems. Since network communication is standardized by IEEE standards so mostly network monitoring softwares comply with IEEE standards.

Network Traffic Monitoring

To monitor the network traffic, it acquires performance statistics of the protocols implemented on OSI layers. After analyzing the statistics itself the software provides recommendations to improve the performance.

Availability

Network monitoring software is also available for wireless networks. In fact it is becoming more popular because of WAP's (wireless access point‘s) easy installation and relatively low cost. Moreover software suppliers are authorized and provide the software that is compliant with ANSI (American National Standards Institute) specifications and IEEE (Institute of Electrical and Electronics Engineers) standards.
