Abstract:
The most widely used protocols for internet communication are Internet Protocol (IP) and Transport Control Protocol (TCP). IP served an important role in internet communication but as the number of internet connecting devices and users grew exponentially, it resulted in the depletion of IPv4 address space. Locator Identifier Separation Protocol (LISP) was introduced to address the issues of scalability, multi-homing and to optimize the routing system for IPv4 and IPv6. LISP used TCP or User Datagram Protocol (UDP) as a transport layer protocol. The basic idea of LISP was to divide the present address space into two parts: the identifier, which is made up of locally routable addresses used for identification, and the locator, which is made up of globally routable addresses used to route traffic in the network. TCP has been present since the beginning of the internet and has gone through many changes and evaluations over the decades, but it still have many flaws left, like a slow start, 3-way handshake to establish a connection which results in large Round-Trip Time (RTT), and slow throughput, while UDP is a not a connection-oriented protocol and UDP packet loss ratio is extremely high. Quick UDP Internet Connections (QUIC) is a new transport protocol that recently got standardized by the Internet Engineering Task Force (IETF). It is introduced to address the flaws of TCP. It supports multiplexing with integrated cryptographic functionalities. LISP is still using TCP/UDP as a transport layer protocol. TCP/UDP is bringing all their flaws to LISP. To overcome this problem, we proposed LISP based QUIC protocol. The experimental results showed that LISP-based QUIC performed better in terms of connection establishment time and throughput. Moreover, it performed better in packet loss ratio and delay time than LISP-based TCP or UDP protocol.
