Due to technological development, many businesses have had to move to the cloud and change their IT infrastructure. This process might be challenging because of Software Defined Networking (SDN) limitations like poor flexibility.
However, the challenge can be overcome. Especially with the support of experts who have great experience in P4 – the Programming Protocol-Independent Packet Processors language for programming the data plane of network devices. At CodiLime, we've been developing network solutions with P4 since 2014.
Let’s talk about your P4 project
Why use the P4 programming language for your project?
P4 makes programming a data plane effective and more manageable by providing such advantages as the possibility for software reuse, building component libraries to move hardware-specific functions to P4, and a painless debugging and upgrading process for P4 programs
Why else is the P4 language worth considering?
P4 flexibility
As opposed to standard switches, P4 enables developers to express packet-forwarding policies as programs instead of revealing fixed-function forwarding engines to users (as in the case of traditional switches).
Ability to process fully custom protocol headers with P4
This feature allows P4 to really stand out compared to traditional switches and routers – they mainly enable the processing of standard and popular protocol headers like Ethernet, IP, TCP, etc. In contrast, the P4 language makes it possible also for custom solutions.
Easy separation of hardware and software components
P4 enables the use of abstract architectures for decoupling low-level aspects from high-level processing details.
Our P4 Developers will help you with:
- Building flexible leaf-spine fabric (based on white box switches that are easily reconfigured when needed thanks to the use of a P4-programmable data plane).
- VNF-offloading (executing typical network functions, such as a firewall, NAT or a load balancer directly on a programmable HW like a switch or smartNIC in a DC environment).
- Service chaining (employing a P4-defined dataplane in the process of creating service chains between virtual, physical or mixed service appliances).
- Writing efficient and portable code in P4 (v14 or v16).
- Taking into account the differences and limitations within existing P4 targets.
- Creating automated test suites using PTF framework.
- Creating custom integration within your networking toolset.
- Integrating your P4 solution into real life networking scenarios.
- Benchmark and debug your hardware or software P4 implementation.
