what is difference between classless and classful routing protocols?

In classful routing, hello messages are not used. While in classless routing, hello messages are used. ... In classful routing, address is divided into three parts which are: Network, Subnet and Host. While in classless routing, address is divided into two parts which are: Subnet and Host.

Difference: Connection oriented and Connectionless service Connection oriented protocol makes a connection and checks whether message is received or not and sends again if an error occurs, while connectionless service protocol does not guarantees a message delivery.

A connected route is one that is assigned directly to an interface. A local route is one that is one that is not known by a protocol. But since static routes are considered a 'protocol', that only happens in the case of secondary addresses on the interfaces.

Common routing protocols include RIP, RIPv2, IGRP, EIGRP, IS-IS and BGP. For the CCNA exam you will need to be well versed in RIP, RIPv2, IGRP and EIGRP. You should be aware of IS-IS and BGP, and be able to configure basic OSPF. Two main types of routing protocols exist - distance vector and link state.

Connection and connectionless TCP is a connection-oriented protocol and UDP is a connection-less protocol. TCP establishes a connection between a sender and receiver before data can be sent. UDP does not establish a connection before sending data.

A RequestDispatcher forward() is used to forward the same request to another resource whereas ServletResponse sendRedirect() is a two step process. In sendRedirect(), web application returns the response to client with status code 302 (redirect) with URL to send the request.

As per difference in both, the applications come where, how to access the resources. In Client-Server, once the connection is made it will be in the state on connected, whereas in case of web testing HTTP protocol is stateless, then there comes logic of cookies, which is not in Client-Server.

Distance vector protocols send their entire routing table to directly connected neighbors. Link state protocols send information about directly connected links to all the routers in the network.

The Connection oriented services establish a connection prior to sending the packets belonging to the same message from source to the destination. On the other hand, the connectionless service considers each packet belonging to the same message as a different & independent entity and route them with a different path.

First is Ad-hoc On-Demand Distance Vector (AODV) routing protocol and second is Optimized Link State Routing Algorithm (OLSR) routing protocol. These algorithms enable the way for optimization of the routing parameters.

OSPF detects changes in the topology, such as link failures, and converges on a new loop-free routing structure within seconds. OSPF has become a popular dynamic routing protocol. Other commonly used dynamic routing protocols are the RIPv2 and the Border Gateway Protocol (BGP).

Routing Protocol Type:The RIP is a distance vector protocol whereas the OSPF is a link state protocol. A distance vector protocol uses the distance or hop counts to determine the transmission path. ... Hop Count Restriction:The RIP allows only up to 15 hops, whereas in OSPF protocol, there is no such restriction.

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. The speed for TCP is slower while the speed of UDP is faster. TCP uses handshake protocol like SYN, SYN-ACK, ACK while UDP uses no handshake protocols. ... TCP has acknowledgment segments, but UDP does not have any acknowledgment segment.

Interior routing protocols are used to communicate within a single autonomous system. Exterior routing protocols are used to communicate between multiple autonomous systems.

Distance vector protocols send their entire routing table to directly connected neighbors. Link state protocols send information about directly connected links to all the routers in the network. ... Link state routing protocols are widely used in large networks due to their fast convergence and high reliability.

HTTP is a Stateless Protocol HTTP is called a stateless protocol because each command is executed independently, without any knowledge of the commands that came before it. This is the main reason that it is difficult to implement Web sites that react intelligently to user input.
