Using the Protocol Analyzer
Traffic flow analysis
The SoftPerfect Network Protocol Analyzer is a free professional tool for analysing, debugging, maintaining and monitoring local networks and Internet connections. It captures the data passing through your dial-up connection or Ethernet network card, analyses this data and then represents it in an easily readable form. The SoftPerfect Network Protocol Analyzer is a useful tool for network administrators, security specialists, network application developers and anyone who needs a comprehensive picture of the traffic passing through their network connection or segment of a local area network.
The SoftPerfect Network Protocol Analyzer presents the results of its network analysis in a convenient and easily understandable format. It also allows you to defragment and reassemble network packets into streams. The program can fully decode and analyse network traffic based on a number of different low level Internet protocols: AH, ARP, BOOTP, DHCP, DNS, ESP, GRE, ICMP, ICMPv6, IGMP, IP, IPv6, IPX, LLC, MSG, REVARP, RIP, SAP, SER, SNAP, SPX, TCP, UDP and VLAN. It also performs full reconstruction of top-level protocols such as HTTP, SMTP, POP, IMAP, FTP, TELNET and others.
The flexible system of fully configurable filters can be used to discard all network traffic except the specific traffic patterns you are interested in. The SoftPerfect Network Protocol Analyzer also has a special packet builder. This tool allows you to build your own custom network packets and send them into the network. You could use this packet builder feature to check your network for robustness against attacks and intruders.
