Open vSwitch - Multilayer Virtual Switch
Open vSwitch is well suited to function as a virtual switch in VM environments. In addition to exposing standard control and visibility interfaces to the virtual networking layer, it was designed to support distribution across multiple physical servers. Open vSwitch supports multiple Linux-based virtualization technologies including Xen/XenServer, KVM, and VirtualBox.

cpp-library network stl template libraryTCPDump - Network Packet Analyzer
TCPDump, a powerful command-line packet analyzer; and libpcap, a portable C/C++ library for network traffic capture. It prints out a description of the contents of packets on a network interface that match the boolean expression. The Packet Capture library provides a high level interface to packet capture systems. All packets on the network, even those destined for other hosts, are accessible through this mechanism.

Modern, powerful open source C++ class libraries and frameworks for building network- and internet-based applications that run on desktop, server, mobile and embedded systems. It has a collection of C++ class libraries, conceptually similar to the Java Class Library, the .NET Framework or Apple’s Cocoa.
cpp-library network stl template libraryflannel - Network fabric for containers, designed for Kubernetes
Flannel runs a small, single binary agent called flanneld on each host, and is responsible for allocating a subnet lease to each host out of a larger, preconfigured address space. Flannel uses either the Kubernetes API or etcd directly to store the network configuration, the allocated subnets, and any auxiliary data (such as the host's public IP). Packets are forwarded using one of several backend mechanisms including VXLAN and various cloud integrations.

IPFire is a server distribution with intended to use as a firewall. It focuses on flexibility, and scales from small to middle sized business networks and home networks. Beginning with a small firewall system of a few megabytes, it is possible to run IPFire as a file server or VPN gateway for staff, branches or customers. This modularity means that yor version of IPFire runs with exactly what you require and nothing more.

Transport Layer Security (TLS) is a cryptographic protocol designed to provide communication security over the Internet. This is an open source Python implementation of TLS 1.2, using the Python Cryptographic Authority's (PyCA's) Cryptography libraries for all cryptographic primitives (e.g. AES, RSA, etc.). This project is part of PyCA's efforts to standardize and improve crypto libraries in Python.
