What are the impacts on the network of introducing new services?
- Exactly what makes up my network traffic
- Who are the users?
- What applications are they using?
- Who and what are consuming the bandwidth? - Are there worms and viruses in my network, where are they, where did they come from, and where are they going?
- Is the quality of service policy working?
NetFlow Tracker harnesses flow information from many NetFlow vendors including CISCO and HP, to give users detailed network traffic insight without the use of probes or appliances. Finally, many critical management questions about the network become easy to answer.....
Regardless of network design (Frame Relay, Multi-protocol Label Switching, and so on.) NetFlow Tracker captures information on all network conversations passing through the interfaces of the supported routers and switches
NetFlow Tracker generates unique databases that collect, store, and present valuable usage-based network data reports. In Version 2 of NetFlow Tracker, that reporting and storage capability has been greatly enhanced with the addition of the Advanced Services Module, which now allows data to be stored for up to 999 years.
Key Features of NetFlow Tracker
• Real-time database – every network flow recorded, per minute, up to the last minute
• Long-term databases - layered long-term historical reports in multiple time frames and time slices
• Extended reporting periods – The real-time data can be stored over extended periods of time (up to 14 days). The long-term database can be configured to store information for several years
• Secure integration with any third party management product, using URLs
• Ability to filter all reports based on any field stored in NetFlow record
• Reports can be tailored to suit specific audiences, e.g. real-time operations vs. capacity planning
• Utilises existing Cisco/other infrastructure; NetFlow Tracker is a software-only solution that requires no additional hardware probes
Key information stored by NetFlow Tracker
• Source and destination IP address
• Source and destination TCP/User Datagram Protocol (UDP) ports
• Which ISP my traffic is going over
• Quality of service fields (ToS and Diff Serv)
• Packet and byte counts
• Input and output interface numbers
• Encapsulated protocol (TCP/UDP)
• Routing information (next-hop address, source Autonomous System (AS) number, destination ISP Carrier, source prefix mask, destination prefix mask)
Security
Monitoring network activity can play a major part in establishing and maintaining network security. Our monitoring software is based on these fundamentals:
Coverage - Most routers in the huge Cisco installed base can be used for network monitoring and with NetFlow Tracker no additional (costly) hardware probes are required.
Complete Visibility - NetFlow Tracker is practically alone in being able to report on every data conversation. The conversations that matter today start and remain small - virus, voice, peer-to-peer, hacking and worms. Only complete visibility makes tracking these conversations possible.
Conversation Awareness and IP Session Tracking - The ability to examine packets and their numerous fields in detail, so that unauthorised and hostile activity can be traced and analysed.
Conversations and Interfaces - More than just a record, knowing the source IP addresses of conversations and their inbound and outbound interfaces is critical to tracking and understanding unusual behaviour.
