Jupiter

Introduction

Jupiter is a high-performance 4-layer network load balance service based on DPDK. It supports TCP and UDP packet forwarding in FULLNAT mode. The load balancing algorithms supported by jupiter include consistent hashing, rr, lc.

• Support TCP, UDP protocol
• Support session maintenance for application
• Support load balance service scale out
• Support million QPS for visitors
• Support query limit for visitors

How to use

1. Compilation

Required OS release: Centos-7.2 or Centos-7.4

tar -xf jupiter.tar.gz
cd jupiter
make rpm-pkg
rpm -i rpmbuild/RPMS/x86_64/jupiter-0.1-1.x86_64.rpm

2. Startup

The default configuration path for jupiter-service is /etc/jupiter/jupiter.cfg. An example for jupiter.cfg as follows :

EAL configuration reference DPDK document.

[EAL]
cores = 1-3
memory = 4096,0
mem-channels = 4

[NETDEV]
name-prefix = jupiter
ip-local-address = 10.0.2.1, 10.0.2.2
kni-ipv4 = 1.1.1.2
kni-netmask = 255.255.255.0
kni-gateway = 1.1.1.254

Reserve huge pages memory:

mkdir -p /mnt/huge
mount -t hugetlbfs nodev /mnt/huge
echo 4096 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages

Load igb_uio module:

modprobe uio
insmod /usr/share/jupiter/kmod/igb_uio.ko
/usr/share/jupiter/tools/dpdk-devbind.py --bind=igb_uio eth1

Load rte_kni module:

insmod /usr/share/jupiter/kmod/rte_kni.ko

Start up jupier-service:

jupiter-service --daemon

Simple Test

1. Test network diagram

2. ab-client configuration

ifconfig eth0 1.1.1.1/24 up
route add -net 10.0.1.0 netmask 255.255.255.0 gw 1.1.1.2

3. nginx-server configuration

ifconfig eth0 1.1.1.3/24 up
route add -net 10.0.2.0 netmask 255.255.255.0 gw 1.1.1.2

4. jupiter-service configuration

Add a TCP virtual service 10.0.1.1:8888 and two nginx service 1.1.1.3:80, 1.1.1.4:80.

ifconfig jupiter0 1.1.1.2/24 up
jupiter-ctl vs/add 10.0.1.1:8888 tcp
jupiter-ctl rs/add 10.0.1.1:8888 tcp 1.1.1.3:80
jupiter-ctl rs/add 10.0.1.1:8888 tcp 1.1.1.4:80

5. ab-client request VIP service

ab http://10.0.1.1:8888/
