Introduction

In this last blog post on NCS5500 Netflow, we presented the NF implementation details: from the software processes to the internal networks used to transport sampled traffic and the CPU protection mechanisms. Also, we provided some important information on the various packet sizes and how should be approached the sampling-interval question.

Today we will present the results of a Netflow test campaign executed in lab last month. We will see how NCS5500 behaves when we push all cursors.

The tests

We will try to check various parameters today, and make sure it doesn’t have any side effects. For instance, we need to make sure we are not impacting the control plane: the routing protocols handled on the same Line Card CPU should not flap or lose update. When possible, we will show the impact on LC CPU.

These tests are executed on 36x100G-A-SE line cards running IOS XR 6.3.15. The card is fully wired to an Ixia chassis, able to push line rate traffic over each interface simultaneously. In some specific tests, we will use a fully loaded chassis (16-slots) with a “snake” configuration: each port is looped to another one to re-inject traffic and load the chassis without requiring 574x 100G testing ports.

The tests have been carried out configuring Neflow v9 on physical but also bundle interfaces. To make the test more realistic, we added URPF v4+v6 to the interface configuration, dampening, ingress+egress QoS and ingress v4+v6 ACLs, LDP and RSVP-TE, and finally multicast (IGMP and PIM).

All the tests have been executed with both v4 and v6 simultaneously.

We made sure that a lot of “new flows” were generated from Ixia using some traffic distribution knobs. Indeed, the “effort” of creating a new entry in the cache compared to updating an existing one is not the same for the nfsrv process.

Let’s get started…

Impact of the packet size

In this first test, we will check the impact on the CPU load when pushing different packet size.

Test parameters:

  • each port is generating 200,000 PPS
  • 1M flows total generated by Ixia
  • sample-interval configured: 1:4000
  • active/inactive timers: 30s/30s
  • timeout rate-limit 10000

Variable parameter(s):

  • packet size: 64B, 128B, 256B, 512B

Measurement:

  • CPU impact on nfproducer, nfsrv, netio

Results:

Picture1.jpg

Comment: during all these tests, we noticed that CPU utilization is rarely completely linear. We will need to accept some margin of errors in the figures collected and presented here.

Conclusion:

  • the packet size doesn’t seem to influence significantly the CPU load
  • it’s something we are expecting for everything above 100B @ L3 since the NPU doesn’t sample more
  • no taildrop observed, no impact on other routing protocols (v4 or v6)

Impact of the port load / bandwidth

In this second test, we are generating IMIX traffic (with packet size variable between 100B and 300B) and we simply adjust the interface load (simultaneously on the 36x ports).

Test parameters:

  • each port is generating 100B-300B packets
  • 1M flows total generated by Ixia
  • sample-interval configured: 1:4000
  • active/inactive timers: 30s/30s
  • timeout rate-limit 10000

Variable parameter(s):

  • interface load: 20%, 40%, 60%, 80%, 100%

Measurement:

  • CPU impact on nfproducer, nfsrv, netio

Results:

Picture2.jpg

We can see with some margin of error in the third measurement that CPU load for nfproducer and nfsrv is growing and reach a “plateau”. This can be easily explained by the shaper used on each NPU. In current release (6.3.2), we use a shaper of 133Mbps. We will increase this number in next releases (to 200Mbps).

Conclusion:

  • bandwidth utilization has, logically, an impact on the CPU load but no taildrop were observed, no impact on other routing protocols (v4 or v6)

Impact of sampling interval

Here, we will use line rate traffic on the 36 ports and we will only change the sampling-interval in our configuration. It will logically have an impact on the number of sampled packets we push from the NPUs to the Line Card CPU. So we expect the CPU load to increase.

Test parameters:

  • each port is generating 512B packets
  • each port is transmitting line rate
  • we use all 36 ports
  • 1M flows total generated by Ixia
  • active/inactive timers: 30s/30s
  • timeout rate-limit 10000

Variable parameter(s):

  • sampling interval: 1:32K, 1:16K, 1:8K, 1:4K, 1:2K: 1:1K, 1:1

Measurement:

  • CPU impact on nfproducer, nfsrv, netio

Results:

Picture3.jpg

Again, we will need to accept some margin of error in the measurement of the last test.

We can see a progression in the CPU utilization, up to a plateau when we reach the shaper. After this value, even if we sample more aggressively, we are not pushing more sampled packets to the LC CPU.

Conclusion:

  • with constant traffic, sampling-interval has, of course, a direct impact on the CPU load but no taildrop were observed, no impact on other routing protocols (v4 or v6)

Impact of the number of flows

In this fourth test, we will check what happens when we exceed the cache size. So we will generate more flows than the maximum cache limit we can configure (1 million entries).

Test parameters:

  • each port is generating 512B packets
  • each port is transmitting line rate
  • we use all 36 ports
  • sample-interval configured: 1:4000
  • active/inactive timers: 30s/30s
  • timeout rate-limit 10000

Variable parameter(s):

  • Number of flows: 1M, 2M, 3M

Measurement:

  • CPU impact on nfproducer, nfsrv, netio

Results:

Picture4.jpg

Very straightforward analysis: no impact at all, the CPU load stays constant.

Conclusion:

  • once the cache reaches its limit, nothing happens: we don’t remove new entries or punt packets or anything
  • impact on LC CPU is not noticeable regardless the actual number of flows passing through the box
  • of course, in such situation, the traffic matrix based on this netflow records will be inacurrate
  • no taildrop observed, no impact on other routing protocols (v4 or v6)

Impact of the active / inactive timers

This fifth test is now stressing a different aspect of the netflow protocol: the record generation. When we manipulate the active and inactive timers, we are influencing the amount of records generated.

Test parameters:

  • each port is generating 512B packets
  • each port is transmitting line rate
  • we use all 36 ports
  • sample-interval configured: 1:4000
  • 1M flows total generated by Ixia
  • timeout rate-limit 50000: note it’s a very high number here, we don’t want to limit the amount of records and potentially pollute the test

Variable parameter(s):

  • active/inactive timers: 30/30, 15/15, 5/5, 1/1

Measurement:

  • CPU impact on nfproducer, nfsrv, netio

Results:

Picture5.jpg

It appears that only nfsrv is impacted by this test, even if we see a small increase in the netio process too.

Quick refresher on the role of nfsvr:

  • Receives NF record packets from nf_producer
  • Creates a new flow cache if not already created, or update a existing flow cache (packet / byte count) for the flow monitor
  • Periodically ages entries form the NF cache into NF export packets
  • Sends the NF export packets to the NF collector using UDP

Not a surprise to see the CPU load occupied by nfsvr increasing when we move to lower active/inactive timers. Since netio is used to transport the NF records, it’s also logical to see a progression of the CPU load when we transmit more and more of them.

Conclusion:

  • nfsvr and netio are the only processes impacted by more agressive active/inactive timing
  • if we have kept a much lower NF record rate-limiter, it’s very likely we would have seen a plateau in the diagram
  • no taildrop observed, no impact on other routing protocols (v4 or v6)

Full chassis

In this test, we used a fully loaded chassis (16 times 36x 100G connected with a “snake topology”) and we configured Netflow on all ports.

Since the netflow is handled at the line card CPU level, the number of line cards makes this test interesting for only one aspect: we used the same collector destination address everywhere.

Test parameters:

  • each port is generating 512B packets
  • each port is transmitting line rate
  • we use all 36 ports
  • sample-interval configured: 1:4000
  • 1M flows total generated by Ixia
  • timeout rate-limit 10000
  • destination address of the collector: 173.173.173.1

Picture of the testbed:

snake.jpg

Conclusion:

  • nfsvr, nf_producer and netio being local to each line cards, nothing noticeable
  • no taildrop observed, no impact on other routing protocols (v4 or v6)

Stress tests

Finally, we performed stress tests:

  • on the line card: reloading it multiple times in a row
  • on the processes: forcing manual restart of the various processes (nf_producer and nfsrv)

  • on the interfaces: we forced flapping on the interfaces where netflow was configured and checked the impact. Both with bundled interfaces and physical interfaces.

  • clear cache record: forces the generation of all the records before flushing the cache entries.

Conclusion

We proved today that Netflow implementation in IOS XR 6.3.15 (and following 6.3.2) is solid and can be stressed without noticing any side effect. We pushed the scale, the sampling-interval, the timers and rate-limiters, etc and obtained consistent behavior and results.
