A Way to Implement Network Services in a Data Center

In recent years, IP-fabric has often been used in data center networks, which is a set of network equipment (usually switches) interacting via control protocols, which provides unified addressing, security, etc. services, as well as data delivery along the optimal route. With such an organization, the implementation of some services is transferred to the virtualization of network functions. This article suggests an effective way to implement virtualization of network functions and deliver traffic to it in the IP fabric of a data center. The method is based on VPP (Vector Packet Processing platform) and FRR (Free Range Routing), VxLAN (Virtual extensible local area network), EVPN (Ethernet VPN) and ICMP (Internet Control Message Protocol) technologies. The results of test measurements of the processing of various traffic on the data plane are shown. The results of experimental tests show that on Xeon Cascade Lake core, VPP technology produces a performance of about 20 Mpps with IPv4 traffic. Combinations of IPv4 lookup, VxLAN, Encap/Decap, and ACL (Access Control List) lookup processing show lower performance.
