NDN-DPDK: High-Speed Named Data Networking Forwarder

NDN-DPDK is a set of high-speed Named Data Networking (NDN) programs developed with the Data Plane Development Kit (DPDK). Included are a network forwarder and a traffic generator.

This software is developed at the Advanced Network Technologies Division of the National Institute of Standards and Technology. It is in pre-release stage and will continue to be updated.

Installation

Requirements
  • Ubuntu 18.04 or Debian 10 on amd64 architecture
  • Required APT packages: build-essential clang-8 git libc6-dev-i386 libelf-dev libnuma-dev libssl-dev liburcu-dev pkg-config python3-distutils
  • Optional APT packages: clang-format-8 doxygen yamllint (see "other build targets" for an explanation)
  • pip and sudo pip install -U meson ninja
  • Intel Multi-Buffer Crypto for IPsec Library v0.55 (optional)
  • DPDK 20.11, configured with meson -Ddebug=true -Doptimization=3 -Dtests=false --libdir=lib build
  • SPDK 20.10, configured with ./configure --enable-debug --disable-tests --with-shared --with-dpdk=/usr/local --without-vhost --without-isal --without-fuse
  • ubpf library, installed to /usr/local
  • Go 1.x
  • Node.js 14.x

You can install the dependencies with ndndpdk-depends.sh.

NDN-DPDK requires hugepages to run. See huge-setup.sh for an example on how to setup hugepages.

Build steps
  1. Clone the repository.
  2. Execute npm install to download NPM dependencies.
  3. Execute make to compile the project.
  4. Execute sudo make install to install the programs to /usr/local, and sudo make uninstall to uninstall them.
Other build targets
  • make godeps builds C objects and generates certain Go source files.
  • make gopkg builds all Go packages.
  • make test runs all unit tests. You can also execute mk/gotest.sh <PKG> to run the tests for a given package.
  • make doxygen builds C documentation (requires the doxygen dependency).
  • To view Go documentation, execute godoc & and access the website on port 6060. You may need to install godoc command: sudo GO111MODULE=off GOBIN=$(go env GOROOT)/bin $(which go) get -u golang.org/x/tools/cmd/godoc
  • make lint fixes code style issues before committing (requires the clang-format-8 and yamllint dependencies).
Compile-time settings

You can change compile-time settings by setting these environment variables:

  • NDNDPDK_MK_RELEASE=1 selects release mode that disables assertions and verbose logging in C code.
  • NDNDPDK_MK_THREADSLEEP=1 inserts nanosleep(1ns) to each thread. This reduces performance significantly, but is occasionally useful when running on a machine with fewer CPU cores.
  • C code other than strategy is compiled with gcc by default; you can override this by setting the CC environment variable.
  • Strategy code is compiled with clang-8 by default; you can override this by setting the BPFCC environment variable.

You must run make clean when switching compile-time settings.

Docker packaging
  1. Build the image: docker build -t ndn-dpdk .
  2. Configure hugepages on the host machine: echo 8 | sudo tee /sys/devices/system/node/node*/hugepages/hugepages-1048576kB/nr_hugepages && sudo mkdir -p /mnt/huge1G && sudo mount -t hugetlbfs nodev /mnt/huge1G -o pagesize=1G
  3. Launch a container in privileged mode: docker run --rm -it --privileged --network host --mount type=bind,source=/mnt/huge1G,target=/mnt/huge1G ndn-dpdk
  4. Run NDN-DPDK service inside the container: ndndpdk-svc
  5. Or run unit tests: export PATH=$PATH:/usr/local/go/bin; cd /root/ndn-dpdk; make test

Note that DPDK is compiled with -march=native flag, so that the Docker image only works on machines with the same CPU model.
