Networking Challenges in OpenStack Clouds
Did you decided that it is time to implement OpenStack to build your Cloud? Have you tested in the lab? Evaluated many distributions available and hired specialized OpenStack resources?

Networking Challenges in OpenStack Clouds
Did you decided that is time to implement OpenStack to build your Cloud? Have you tested in the lab? Evaluated many distributions available and hired specialized OpenStack resources? However, when the environment goes into production, Neutron is not integrating with the physical network?
If the above story closely resembles what you have faced, this post will unconceal the many challenges of Networking with any OpenStack distribution and how VMware NSX is the missing piece for your Cloud.
Networking and Security Challenges with OpenStack
Since its creation, the biggest challenges of OpenStack Clouds implementations are automation, integration and orchestration of the required networking and security components at the physical infrastructure layer. The main difficulty is that these environments are extremely heterogeneous and most of the devices do not have an open and programmable interface for configuration and, thus, the initial way of running OpenStack was to pre-provisioning the network manually and only use basics functionalities when implementing security services.
With the rise of Network Virtualization solutions and evolution of Open vSwitch, some of these challenges were solved, making it possible to create an abstraction layer from the physical elements of infrastructure and automate the virtual network through the programmable interface Continue reading

Linux 4.11 kernel extends packet sampling support
Introduce psample, a general way for kernel modules to sample packets, without being tied to any specific subsystem. This netlink channel can be used by tc, iptables, etc. and allow to standardize packet sampling in the kernel commitThe psample netlink channel delivers sampled packet headers along with associated metadata from the Linux kernel to user space. The psample fields map directly into sFlow Version 5 sampled_header export structures:
| netlink psample | sFlow | Description |
|---|---|---|
| PSAMPLE_ATTR_IIFINDEX | input | Interface packet was received on. |
| PSAMPLE_ATTR_OIFINDEX | output | Interface packet was sent on. |
| PSAMPLE_ATTR_SAMPLE_GROUP | data source | The location within network device that generated packet sample. |
| PSAMPLE_ATTR_GROUP_SEQ | drops | Number of times that the sFlow agent detected that a packet marked to be sampled was dropped due to lack of resources. Agent calculates drops by tracking discontinuities in PSAMPLE_ATTR_GROUP_SEQ |
| PSAMPLE_ATTR_SAMPLE_RATE | sampling_rate | The Sampling Rate specifies the ratio of packets observed at the Data Source to the samples generated. For example a sampling rate of 100 specifies that, on Continue reading |

BGP Configurations on HP Routers
Today I am going to talk about the BGP configurations on the HP routers. I already posted the articles on the BGP configurations earlier where i defined the basic configurations on the Cisco and Juniper routers. Apart from these configurations I already put the basic information of the BGP as well. Below are some of the articles for which you can refer to study yourself step by step.

BGP configurations on Cisco routers
Today I am going to have the basic configurations on HP routers with the topology. Below is the basic topology and the basic BGP configuration as below. The Topology and the IP addresses used here are only for the demo purposes and has no relevance with any of the live or enterprise networks.
Below is the demo topology showing the use of the HP routers where BGP is configured in the MPLS environment. This is just a example to showcase the topology. I will come up with the configurations on HP routers in the MPLS environment in later stage. As of now first we need to talk about the basic BGP on the HP routers and step by step we Continue reading

(Not-so-very) Early Network Automation
If you’re not old enough to know otherwise, you’d think (based on recent hype) that we discovered network automation a few years ago. Not true. One of my readers sent me a link to excellent Managing IP Networks with Free Software presentation from NANOG26 (October 2002).
I found the presentation awesome, nothing new, and extremely sad… all at the same time.
