Frame Relay network are now being converted to MPLS type of network more rapidly. MPLS type of network helps the Network Administrators to easily manage the Network and MPLS network architecture is simple than traditional Frame Relay or packet switching networks.
Monitoring Network traffic through NetFlow export becomes very handy in MPLS type of networks. Consider a network which has below given architecture:
Task of an Administrator:-
Given task for Administrator is to monitor internet traffic of Site A, Site B and traffic between Site A and Site B. The Administrator of this network is using NetFlow Analyzer and monitoring all the Site Routers and Internet Router .
IP Grouping :-
Since, he is alre…
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 …
During these rough economic times that we are currently going through, every single penny spent on enhancements, upgrades in the network to accommodate future demand is questioned. To make do with the existing resources with cost-cutting in mind is the most ideal solution until the economy recovers.
This mindset has a direct implication on every organization and, eventually, every department within it. Capacity planning plays a major role to cut the cost spending on enhancing the network or bandwidth to accommodate growth.
The Capacity Planning reports in NetFlow Analyzer’s Professional plus edition will help you to identify bandwidth usage growth and application growth over a period of time and it …
Both Cisco 6500 & 7600 serve as Core devices on a network to distribute large amount of traffic. The high volume of packets and packet rates of traffic on some device links which leads to more utilization of CPU and memory for performing traffic analysis in this scenario. One solution to avoid this problem is sampling. Sampling defines that instead of every packet, 1 out of N packets (where N is the sampling rate) is captured and sent to the NetFlow Analyzer for traffic analytics. Based on the information in 1 packet, the traffic pattern for the rest of the packets is constructed.
The sampling rate is indicated in a header field of NetFlow version 5 (same sampling rate fo…
The previous blog dealt with Billing and as a continuation here is a brief account of IP group billing which is one of the unique features of NetFlow Analyzer.
IP Group Billing:-
Consider a scenario where billing has to happen across different users from different departments sharing the same link. This scenario is very typical in large enterprises where a given project is handled by different departments & they have their unique ways of using the bandwidth to handle the project. In this scenario, creating IP Groups for each project and associating it with the IP Groups with a bill plan simplifies many complexities involved in billing. This type of bill plan could also help ISPs that cater to a diverse set of …
This blog post is about Billing with NetFlow using NetFlow Analyzer which is quite a rarity in any other product of its kind in the market.
Advantages of Billing Module:-
NetFlow or sFlow technology involves checking the packets traversing a router interface to identify the actual traffic. The high volume of packets and packet rates of traffic on some router links causes the router to use higher CPU and memory during such an analysis. Sampling is solution to be used when flow analytics has to be done on a device. Sampling defines that instead of every packet, 1 out of N packets (where N is the sampling rate) is captured and sent to the NetFlow Analyzer for traffic analytics. Based on the information in 1 packet, the traffic pattern for the rest of the packets is constructed.
Various devices are capable of exporting sample based flows like sFlow (from INMON and available in a wide ran…
Managing, Controlling and Measuring the bandwidth is a huge task to anyone administrating corporate networks. Measuring the bandwidth used is a priority before managing it. NetFlow Analyzer helps you measure bandwidth usage for your enterprise with which you can crosscheck your bandwidth usage as given by your service provider. The IP grouping, interface grouping helps in creation of virtual departments for ease of bandwidth monitoring and accounting.
This blog we have come with very different scenario of IP group, which is about IP accounting and Billing or Charge back.
Consider a Corporate services network which has lot of projects hosted and group of people are working in each project. Th…
Our last blog discussed about Firewalls with NetFlow or sFlow support and outlined the sFlow configuration to be done on FortiGate Firewall devices. Adding to this, below is the configuration for CheckPoint Firewall and SonicWall Device.
CheckPoint Firewall NetFlow Configuration:
CheckPoint IPSO 6.1 introduces support for NetFlow services, which you can use to collect information about network traffic patterns and volume. To provide this information, IPSO tracks network “flows.” A flow is a unidirectional stream of packets that share a given set of characteristics. Click Configuration >Traffic Management > NetFlow to access the NetFlow Configuration page on the UI of Check Point. IPS…
