Open Source Networking Software

The nanomsg library is a simple high-performance implementation of several "scalability protocols". These scalability protocols are lightweight messaging protocols that can be used to solve a number of very common messaging patterns, such as request/reply, publish/subscribe, surveyor/respondent, and so forth. These protocols can run over a variety of transports such as TCP, UNIX sockets, and even WebSocket. This pattern is useful for solving producer/consumer problems, including load-balancing. Messages flow from the push side to the pull side. If multiple peers are connected, the pattern attempts to distribute fairly. nanomsg is a socket library that provides several common communication patterns. It aims to make the networking layer fast, scalable, and easy to use. Implemented in C, it works on a wide range of operating systems with no further dependencies. The communication patterns, also called "scalability protocols", are basic blocks for building distributed systems.

this tool tries to repair your broken pcap and pcapng files by fixing the global header respectively packet blocks and recovering the packets by searching und guessing the packet headers or blocks

FRRouting (FRR) is a free and open-source Internet routing protocol suite for Linux and Unix platforms. It implements BGP, OSPF, RIP, IS-IS, PIM, LDP, BFD, Babel, PBR, OpenFabric and VRRP, with alpha support for EIGRP and NHRP. FRR’s seamless integration with native Linux/Unix IP networking stacks makes it a general-purpose routing stack applicable to a wide variety of use cases including connecting hosts/VMs/containers to the network, advertising network services, LAN switching and routing Internet access routers, and Internet peering. FRR has its roots in the Quagga project. In fact, it was started by many long-time Quagga developers who combined their efforts to improve on Quagga’s well-established foundation in order to create the best routing protocol stack available. We invite you to participate in the FRRouting community and help shape the future of networking.

MsQuic is a Microsoft implementation of the IETF QUIC protocol. It is cross-platform, written in C and designed to be a general-purpose QUIC library. MsQuic also has C++ API wrapper classes and exposes interop layers for both Rust and C#. QUIC has many benefits when compared to existing "TLS over TCP" scenarios. MsQuic has several features that differentiate it from other QUIC implementations. Optimized for client and server. Optimized for maximal throughput and minimal latency. Asynchronous IO. Receive side scaling (RSS) support. UDP send and receive coalescing support. All packets are encrypted and handshake is authenticated with TLS 1.3. Parallel streams of (reliable and unreliable) application data. Exchange application data in the first round trip (0-RTT). Improved congestion control and loss recovery. Survives a change in the clients IP address or port. Stateless load balancing.

Zuul is an L7 application gateway that offers many capabilities, including dynamic routing, monitoring, security, resiliency and more. It is used in the backend of the Netflix streaming service as a front door for all requests from devices and web sites. Zuul is ideal for cases like this where API traffic volume and diversity can become overwhelming and cause production issues to arise suddenly and without warning. Zuul has a broad range of filters that enable it to perform multiple functions quickly and apply functionality to services like Netflix. These functions include security authentication, dynamic routing, stress testing, load shedding and more.

Serf is a decentralized solution for service discovery and orchestration that is lightweight, highly available, and fault tolerant. Serf runs on Linux, Mac OS X, and Windows. An efficient and lightweight gossip protocol is used to communicate with other nodes. Serf can detect node failures and notify the rest of the cluster. An event system is built on top of Serf, letting you use Serf's gossip protocol to propagate events such as deploys, configuration changes, etc. Serf is completely masterless with no single point of failure. Serf is first and foremost a library with a command-line interface, serf. The Serf library is independent of the command line agent, serf. The serf binary is located under cmd/serf and can be installed stand alone by issuing the command go get -u github.com/hashicorp/serf/cmd/serf.
