Information About Static Routing Routers forward packets using either route information from route table entries that you manually configure or the route information that is calculated using dynamic routing algorithms. Static routes, which define explicit paths between two routers, cannot be automatically updated; you must manually reconfigure static routes when network changes occur. Static routes use less bandwidth than dynamic routes. No CPU cycles are used to calculate and analyze routing updates. You can supplement dynamic routes with static routes where appropriate. You can redistribute static routes into dynamic routing algorithms but you cannot redistribute routing information calculated by dynamic routing algorithms into the static routing table.

Signature: Date: .~ Stellenbosch University http://scholar.sun.ac.za Abstract Routing policies for packet-switched communication networks must be able to adapt to changing traffic patterns and topologies. We study the feasibility of implementing an adaptive routing policy using the Q-Learning algorithm which learns sequences of actions from delayed rewards. The Q-Routing algorithm adapts a network's routing policy based on local information alone and converges toward an optimal solution. We demonstrate that Q-Routing is a viable alternative to other adaptive routing methods such as Bellman-Ford. We also study variations of Q-Routing designed to better explore possible routes and to take into consideration limited buffer size and optimize multiple objectives. 11 Stellenbosch University http://scholar.sun.ac.za Opsomming Die roetering in kommunikasienetwerke moet kan aanpas by veranderings in netwerk- topologie en verkeersverspreidings.

  • RIP: Routing Information Protocol a Routing Protocol Based on the Distance-Vector Algorithm
    Laboratory 6 RIP: Routing Information Protocol A Routing Protocol Based on the Distance-Vector Algorithm Objective The objective of this lab is to configure and analyze the performance of the Routing Information Protocol (RIP) model. Overview A router in the network needs to be able to look at a packet’s destination address and then determine which of the output ports is the best choice to get the packet to that address. The router makes this decision by consulting a forwarding table. The fundamental problem of routing is: How do routers acquire the information in their forwarding tables? Routing algorithms are required to build the routing tables and hence forwarding tables. The basic problem of routing is to find the lowest-cost path between any two nodes, where the cost of a path equals the sum of the costs of all the edges that make up the path. Routing is achieved in most practical networks by running routing protocols among the nodes. The protocols provide a distributed, dynamic way to solve the problem of finding the lowest-cost path in the presence of link and node failures and changing edge costs. One of the main classes of routing algorithms is the distance-vector algorithm. Each node constructs a vector containing the distances (costs) to all other nodes and distributes that vector to its immediate neighbors. RIP is the canonical example of a routing protocol built on the distance-vector algorithm. Routers running RIP send their advertisements regularly (e.g., every 30 seconds). A router also sends an update message whenever a triggered update from another router causes it to change its routing table.

Distributed, Dynamic Routing Protocols • Distributed because in a dynamic network, no single, centralized node “knows” the whole “state” of the network. • Dynamic because routing must respond to “state” changes in the network for efficiency. • Two class of protocols: Link State and Distance Vector. 2 Link State Protocol • Each node “floods” the network with link state packets (LSP) describing the cost of its own (outgoing) links. – Link cost metric = typically delay for traversing the link. – Every other node in the network gets the LSPs via the flooding mechanism. • Each node maintains a LSP database of all LSPs it received.

  • 7/16 Dynamic Routing
    7/2016 SATEL technical bulletin SATELLAR Dynamic Routing “A router with dynamically configured routing tables is known as a dynamic router. Dynamic routing consists of routing tables that are built and maintained automatically through an ongoing communication between routers. This communication is facilitated by a routing protocol, a series of periodic or on-demand messages containing routing information that is exchanged between routers. Except for their initial configuration, dynamic routers require little ongoing maintenance, and therefore can scale to larger internetworks. Dynamic routing is fault tolerant. Dynamic routes learned from other routers have a finite lifetime. If a router or link goes down, the routers sense the change in the internetwork topology through the expiration of the lifetime of the learned route in the routing table. This change can then be propagated to other routers so that all the routers on the internetwork become aware of the new internetwork topology. [https://technet.microsoft.com/en-us/library/cc957844.aspx]” Dynamic routing benefits: • Easy setup of routing • Fast setup of routing • Load sharing by routing • Redundancy by routing SATELLAR support dynamic routing protocol by providing OSPF (Open Shortest Path First) functionality. SATELLAR uses the OSPFv2 daemon from the Quagga Routing Suite to implement OSPF. More information, such as full documentation, can be found on the following web page: http://www.nongnu.org/quagga/ In the following image, there are two redundant paths from SCADA system to remote network. The router connected to SATELLARs is an OSPF enabled router, and thus the OSPF enabled SATELLARs and the gateway router will be able to communicate with the dynamic routing protocol.

Accepted 06 April, 2011 The heartbeat of network is the routing services which are available upon the execution of protocols. Many routing protocols emerge over one another to strive for betterment in performing the main function of routing the packets to destination efficiently. Despite the superiority of the new protocols in certain feature, the old routing information protocol (RIP) is still widely used due to its simplicity. RIP updates its routing table on a constant interval period by checking the existence of neighbor nodes and changes on the path availability. This mechanism, however, has some drawbacks of bandwidth consumption and higher routing overhead generation. This paper studies the affect of periodic update mechanism on the consumption of bandwidth and proposes a new routing update mechanism. Our technique eliminates the periodic update mechanism in RIP and replaces it with full triggered update by topology change detection mechanism (TRIP).
