Source/Destination tab helps find the traffic from an individual host passing through a specific interface. The Source table will group all the source IP address in the conversation and the total traffic contributed by that host will be displayed. You can further drill down to an IP address/host to view the destination host with the application used and the amount of traffic transferred. This would be the same for Destination tab also.

 




Many customers have doubts regarding the IP that is shown as the top contributor under the conversations tab is not the top contributor in the Source/Destination tab. This is because, the conversations  tab lists every conversation happened whereas the Source/Destination tab will group those conversations based on Source/Destination IP address. When grouping is done, the top IP in the conversation might have less traffic compared with the other IP address. So, combining the conversations results in traffic difference in this tab.




This tab accounts for the IN and OUT traffic of an interface separately. For example let’s assume there is traffic coming IN from the Internet to your LAN and you are monitoring your WAN Interface, the Source IN will be the public network IP Address and the Destination IN will be your LAN IP.

 

If traffic is from your LAN to the internet through WAN interface the Source OUT will be your LAN IP and the Destination OUT will be the internet IP.

 

Source/Destination Tab in IP Groups:

 

The function of these tabs will be the same but there will be no IN or OUT. This is because the accounting of traffic is different from the Interfaces. In a conversation if the destination IP address matches with the credentials for that IP Group, this conversation will be accounted as IN traffic for that IP groups. Similarly, if the Source IP matches it will be accounted as OUT traffic.


 



Therefore in the Source tab will be accounting the Source IP address from which the destination is contacted and the Destination tab will show the IP addresses to which the groups was trying to communicate.




Hope this helps.

Some frequently answered questions of the Application, Source and Destination tabs in NetFlow Analyzer have been handled in this blog.

Our primary focus would be on the ‘Applications’ tab which displays information on the applications used in the link along with the amount of data handled by that particular application and the bandwidth consumption involved.

NetFlow Analyzer maps the application on the basis of the port and protocol used in a conversation. Application mapping is done by prioritizing the lower port number used in a conversation. We cannot map the application name based on source/destination port number. For example,

      Src IP                   Dst IP             SrcPort       DstPort       Protocol

192.168.90.12    172.16.100.19       88              443             TCP

In the mentioned conversation, NetFlow Analyzer checks if any application has already been mapped for port 88 failing which it checks for the port 443 and maps under HTTPS.

Applications contributing more than 1KB of data is stored in the historic tables.


Why Application showing '_App'?


NetFlow Analyzer have 10000 Application names stored in its database. Any application that falls out of this category will be categorized as '_App', based on the protocol used.

This is why '*' is displayed for the port number in the ‘Conversation’ tab when the time period selected is more than 6 hours.

In such cases, clicking on show ports, based on which the corresponding application can be found and added through Application / QoS Mapping --> Add. The ‘Show Ports’ will be available within 24 hours of collection of data.



Why is the drilled amount of traffic less?


In some applications, the amount of traffic shown in the Application tab on drilling down will be less. This is because the drill down for an Application is queried from the conversations table which stores the top 100 records of unique conversations. If the conversation corresponding to a given application does not fall in the top 100, then it will not be displayed in the conversation table. This is exactly why the discrepancy occurs.



Hope this helps.

Are you an ISP or MSP trying to monitor client's bandwidth utilization and bill them based on the usage? The solution for your monitoring need would be ManageEngine NetFlow Analyzer.

Why ManageEngine NetFlow Analyzer?

ManageEngine NetFlow Analyzer is the only tool which does NetFlow, sFlow , IP FIX, jFlow, AppFlow analysis for bandwidth monitoring and has billing module integrated with it to make ease of billing process.

Earlier ISP's used SNMP based tools to calculate monthly data from customer’s edge router (called as CPE's) and then manually calculate the bill based on 95th percentile or volume of data used. This manual process was very time consuming and tedious for the Network Administrator who is responsible for monitoring activities.

Birth of NetFlow based traffic analysis  made this process easy and provided in-depth visibility to network traffic across that router.

NetFlow Billing:-

NetFlow data has highly granular information about the source and destination involved with the traffic, the application used, the traffic volume and so on.

NetFlow Analyzer with its Billing  module gives real-time information on bandwidth consumption using NetFlow data which gives the enterprises and ISPs the ability to plan and manage their network infrastructure better.

Even if your customer or client asks for details  about a bill you presented for charge back, the requested information is not just at your fingertips, but highly professional, neatly formatted, detailed PDF reports which are presentable to back-up your bills.

We have discussed much on ISP and Enterprise Billing in our earlier blogs

Scenario :-

As an ISP or MSP monitoring the typical network as given in below mentioned diagram, we as Manage Engine NetFlow Analyzer TAC team help you with this blog to make sure how you can effectively use NetFlow Analyzer to monitor the devices and bill them based on usage.



First Approach:-

You can enable NetFlow on the each customer CPE equipment and monitor only  the WAN interface in NetFlow Analyzer and create bill plan for each customer and associate the corresponding WAN interface.

Second Approach :-

If you do not have control over CPE's on Customer edge, Monitor the Intermediate router WAN interfaces and create IP group with customer’s IP network or range and associate the corresponding interface of Intermediate router to which they are connected. Then create Bill Plan for each customer and associate the corresponding IP group.

With highly advanced technology development, the overhead on Network Administrators in ensuring prompt delivery of business critical applications over the WAN is very high. Video conferencing is predominantly taking place in major organizations for a variety of reasons like less cost, more productivity and a whole lot of advantages it can offer.

Video conferencing will take place between different branch locations within the same country or over the WAN between different countries. A Network Administrator needs to ensure smooth conferencing of video and avoid undesirable factors such as delay, packet loss and jitter, which are most likely to hamper the quality of the video.

In general, the Network Administrator would adjust bandwidth allocation in order to handle quality related issues for media rich traffic. With Cisco Medianet, this task has become really simple as the networks get intelligent enough on their own. To ensure effectiveness of the changes that have been made on the network.

Video traffic Quality  Monitoring:- 

Network Administrators can now easily configure their devices for video traffic monitoring through Medianet and Mediatrace reports of NetFlow Analyzer.

The illustration shows a video conferencing between 2 sites over WAN for about 4 hours, NetFlow Analyzer is used to monitor live video traffic between these 2  sites to know the performance over WAN. 

Medianet and Mediatrace Report from NetFlow Analyzer:

 

We have not stopped with this, In our next release, you won't need to create monitors for Medianet and Mediatrace reporting. We have brought in a feature called On Demand report in which you specify the session details and continue monitoring the media rich traffic in real time basis.

The mood seems to be very light and happy. Its holiday season and let us try to do away with the conventional things that we normally talk about. It is that time of the year when we put an end to things and gear up for a fresh start. 

 

It is that time of the year when a lot of us introspect what we wanted at the beginning of this year and how much of it has been achieved. This kind of an analysis certainly helps in making our lives better. The bottomline of all of this is that, we normally have the tendency to rely on the past and plan for the future, the same way we generate ‘Capacity Planning’ reports in NetFlow Analyzer.

 

Our networks are the way we made them and it is very natural to draw some comparisons to real life. We have made them as a result of our thinking and imagination. We are living at a time where geography is not a barrier for business. It does not really matter where we are located, thanks to the advent of telepresence and video calls. To ensure seamless connectivity, the IPSLA module helps a great deal.

 

The Enterprises slowly but surely did away with the concept of time. Had Einstein lived today, the true color of relativity would have been right in front of him. When it is morning in the India centre, it is afternoon in Hongkong office and midnight in the sales office in the US. Time does not even matter for running business. It is an era of 24x7 working environment. No matter what, the quality of service has to be maintained at least to the minimum of standards for a ‘good’ from your management and the maximum for a ‘very good’ and the optimum for a ‘fantastic’ (which never really happens). Our CBQoS reports try to make it happen for you so that your paycheck as a Network Administrator goes up.

 

Just like we have a first aid kit at every place we are, be it our car or office or home, to be prepared to face any anomalies of network health is important. The security analytics reports help a great deal in this direction.

 

These are simple real-life analogies to some key features of NetFlow Analyzer. Clearly, they measure up to some important things in real life that one cannot ignore. To overlook any of these aspects in either your network or your life, could and would spell nothing but trouble.

 

So, it is now time to put to the best use, the resources you have in life for a fruitful 2012 and exploit every feature in NetFlow Analyzer for a smooth, healthy and an effective 2012 for your network.

 

Wishing all very happy holidays!

A quick Skype call to your niece, last minute business meetings in WebEx, Jingle Bells streaming on You Tube, it is that time of the year again. It’s Christmas time. Everyone is in the holiday mood.  What else, other than this holiday season could be the best example to demonstrate the importance of video traffic? Wishing your loved ones have never been this easy, thanks to the applications that support video conferencing.

The growth in video traffic has been tremendous, especially in the last two years. More enterprises are turning to rich media based communications to cut costs involved in traveling and also to improve business relationships.

According to Cisco’s Visual Networking Index, Internet video traffic has occupied 40% of the consumer Internet traffic and is expected to reach a whopping 50% by 2012. The sum of all forms of video (TV, video on demand [VoD], Internet, and P2P) will continue to be approximately 90 percent of global consumer traffic by 2015.

Also, 19.7 percent of top Managed Service Providers (MSP) offer video conferencing and telepresence services to customers; and 12.7 percent of top MSPs offer managed video surveillance services to customers.  To meet with the growing expectation in rich media traffic and provide users with the best possible video experience, MSPs need tools that make video monitoring possible.

Cisco Medianet
is an intelligent network optimized for rich media traffic to enhance user experience while reducing complexity and operating costs involved. It helps you to detect and troubleshoot issues related to different media and application types like telepresence, video surveillance, desktop collaboration, and streaming media to deliver the best experience. Medianet can automatically detect and configure media endpoints along with detecting and responding to changes in device, connection, and service availability.

Cisco Medianet reporting on NetFlow Analyzer enables you to monitor the quality of video traffic to give you a rich user experience. Medianet reports from NetFlow Analyzer provide in-depth visibility into your network bandwidth consumption patterns with regards to rich media traffic like video traffic. The Medianet Reports makes troubleshooting simple thereby helping you save time and money. So go ahead and make your 2012 wish list for a hassle-free media experience. Let the Jingle Bells ring!
