Introduction to the IP-DLC Link Service
This section describes the overall architecture of the Host Integration Server system with IP-DLC link service functionality.
IP-DLC is a Host Integration Server feature that provides SNA connectivity for applications using dependent and independent sessions over a native IP network. It implements the HPR/IP protocol, which is also known as HPR over IP or Enterprise Extender. Each SNA packet is transmitted natively across the IP network as a UDP datagram.
