Abstract

Today's enterprise networks rely on a variety of middleboxes. These middle boxes provide various improvements on services in the network such as security, management, performance and scalability. Some of the popular examples of middle boxes are Proxy, NAT, Load-Balancer, Firewall, DPI etc. Even though middleboxes offer significant benefits, they introduce new challenges such as difficulty in ensuring service chaining. Service chaining virtually inserts services into the flow of network traffic. As packets traverse the network, their headers and contents may get modified by middleboxes that are deployed along the network path; e.g., NAT and Load-Balancer rewrites IP header, whereas proxy terminates sessions. These modifications eliminate the possibility of re-purposing available header fields such as DSCP bits in the IP header for realizing service chain.
