g mechanism for creating flow control e.g. in PACKET_OUT operation which requires packet to be matched that allows forwarding before the flow of packets. Multiple auxiliary connections are introduced (TCP, UDP, TLS, or DTLS) in version 1.3 of OpenFlow protocol, which are capable of controlling nay type or subtype of OpenFlow messages. REPLICATION Open Flow provides numerous techniques for packet replication. The reserved virtual ports ANY and FLOOD are mainly used for the replication of the packets e.g., LLDP used to assemble topology for the controller, often uses FLOOD as its output port. Group tables permits the grouping of ports into an output ports sets for enabling multicasting, fast-failover, indirection and multipath. There are four group tables in a list of the action buckets where apparently egress port is specified and one of the actions is output, but only two are necessary: All: It is used for multipath its nature is more related with live/live video feeds or in the multipath where reformation is needed at the end nodes. This multipath is different from the IP forwarding perceptions. In this all action buckets in the list have to be performed. Indirect: It is used to encourage the concurrence behaviour of the next hop in IP forwarding for rapid convergence. Consecutive replication is permitted by Action lists in Apply action by constructing using a list of output/port actions. FORWARDING ABSTRACTION WORKGROUP (FAWG) OpenFlow switch works effectively with software-based switch which are highly versatile in scaling and packet manipulation characteristics or with a hardware- forwarding entity that follows to some simplifying presumptions e.g., large, wide, deep, and multi-entrant memories like a TCAM. However, each switches functionality dependent on their vendors which results in a remarkable variation within the support of all packet Downloaded: 4/15/2022 9:44:49 AM Nova Southeastern University IP Address: 137.52.76.29 Introduction to OpenFlow manipulations enabled by the set of OpenFlow multi-tables,
