Label exchange protocol includes MPLS LDP, CISCO TDP and BGP (used by MPLDVPN), RSVP used by MPLS TE.

The label exchange protocol bind label with network learned via routing protocol.

Control Plane makes use of label exchange protocol to create and maintain label internally and to exchange label with other device.

MPLS Control Plane is used to build FIB table from the information of RIB and LFIB table based upon label exchange protocol.

MPLS control plane indicates how the updates are sent from one PE to another PE router.

Question: What is data plane and control plane in MPLS?

Routing is performed in the control plane.

Control plane acts as a decision maker in data forwarding.

Control plane packets are locally originated by the router itself.

It includes Spanning Tree Protocol (STP), Address Resolution Protocol (ARP), Routing Information Protocol (RIP), Dynamic Host Configuration Protocol (DHCP) etc.

Control plane packets are processed by router to update the routing table.In general, we can say in control plane it is learned what and how it can be done.Control plane performs its task independently.Control plane responsible about how packets should be forwarded.It is responsible for building and maintaining the IP routing table.Control plane refers to the all functions and processes that determine which path to use to send the packet or frame.Some key features of control plane are enlisted below – In a single line it can be said that it is responsible for How packets should be forwarded. Means here the router makes its decision. Control plane is responsible for populating the routing table, drawing network topology, forwarding table and hence enabling the data plane functions. In Routing, control plane refers to the all functions and processes that determine which path to use to send the packet or frame. Control packets originate from or are destined for a router. The routing table contains destination addresses and the outgoing interface associated with them. It is part of the theoretical framework used to understand the flow of information packets between network interfaces or the control plane is the part of a network that carries signaling traffic and is responsible for routing. Question: What is control plane in networking?Īnswer: The control plane is that part of a network which carries information necessary to establish and control the network. Separation of both the planes also supports Denial-of-Service attack detection. This approach helps in more control over decision logic.

Infact separation of control and data plane helps in areas like network virtualization, Layer 3 routing decision taking, Egress selection i.e.

Question: Why do we separate the control plane and the data plane?Īnswer: The Software control of the network can evolve independently of the hardware. Router inserts the results of the control-plane protocols into Routing Information Base (RIB) and Forwarding Information Base (FIB).ĭata plane software or ASICs uses FIB structures to forward the transit traffic.ĭownload this Data Plane vs Control Plance table here. Includes decrementing TTL, recomputing IP header checksum etc. Switching (packet forwarding) is performed in the data (forwarding) plane Routing (exchange of routing information) is performed in the control plane. The routers/switches use what the control plane built to dispose incoming and outgoing frames and packetsĬontrol plane is the process of learning what we will do before sending the packet or frame.ĭata plane is moving the actual packets based on what we learned from control plane. Makes decisions about where traffic will be sent.Ĭontrol Plane = Learning what we will do.įorwards traffic to the next hop along the path to the selected destination network according to control plane logic.ĭata Plane = Actually moving the packets based on what we learned.Ĭontrol plane packets are destined to or locally originated by the router itself.ĭata plane packets go through the router.Ĭontrol plane packets are processed by the router to update the routing table information. The data plane process is responsible for actual forwarding of IP packet. The control plane process is responsible for building and maintaining the IP routing table.
