Ensure Symmetrical Traffic Flow, to prevent the Dropping of Response Packet by the Firewall, on the Active-Active Data Centers

By Irwan Piesessa Benfano Soewito

DOI:, Pub. Date: 8 Jun. 2018

This paper illustrates the problem in the Active-Active Data Centers of an organization, where response traffic from the destination server is dropped by the firewall because the initial traffic from the client departs from another firewall in different Data Center (asymmetric traffic). This problem can be solved by two proposed solutions, namely the implementation of the BGP Community attributes and OSPF over GRE tunnel. The case study also compares both proposed solutions in terms of recovery time, packet loss, ICMP response time and TCP three-way handshake time for HTTP connection.
