SVR is an overlay inter-networking protocol that operates at the session layer. SVR provides end-to-end communication of network requirements not possible or practical using network header layers. SVR uses application layer cookies that eliminate the need to create and maintain non-overlapping address spaces necessary to manage network routing requirements. SVR is an overlay networking protocol that works through middleboxes and address translators including those existing between private networks, the IPv4 public internet, and the IPv6 public internet. SVR enables SD-WAN and multi-cloud use cases and improve security at the networking routing plane. SVR eliminates the need for encapsulation and decapsulation often used to create non-overlapping address spaces.
