What are the different types of routing algorithms?
Routing Algorithms can be classified based on the following:
- Static or Dynamic Routing,
- Distributed or Centralized,
- Single path or Multi-path,
- Flat or Hierarchical,
- Intra Domain or Inter-Domain,
- link State or Distance Vector.
What are the two types of routing protocols?
There are two types of routing protocols:
- Interior Gateway Protocols (IGP): These routing protocols exchange routing information within an autonomous system.
- Exterior Gateway Protocols (EGP): These routing protocols are used to route between autonomous systems.
What is XY algorithm?
In XY routing algorithm, if the Y offset is greater than zero, then the packet is routed to the right (west buffer). If the value is less than zero, then moved to left (east buffer). However, if the Xoffset is not zero, then packet routed up or down along y-axis.
What are the types of router?
There are five main types of routers in the market according to the application category. They are wired routers, wireless routers, core routers, edge routers and VPN routers. Basic information for the above is provided for you when choosing a right one among the various routers.
WHAT IS routing table types of routing table?
To forward incoming data packets, a router learns all available routes in the network and stores them in a table known as the routing table. There are two types of routes: static route and dynamic route. A router can learn these routes through two types of routing: static routing and dynamic routing, respectively.
What is static and dynamic routing?
In static routing, user defined routes are used in routing table. In dynamic routing, routes are updated as per the changes in network. Static routing may not follow any specific protocol. Dynamic routing follows protocols like BGP, RIP and EIGRP.
What is Dimension order routing?
Dimension-ordered (X-Y) routing Dimension ordered (X-Y) routing (shown in fig 3) restricts all turns from y-dimension to x-dimension. This prohibits two anti-clockwise and two clockwise turns which is more than what is actually required.
Is XY routing deadlock free?
Traditional XY routing, which is often used in torus and mesh topology, has the advantage of deadlock- and livelock-free characteristics and it is easy to design.
Adaptive routing algorithm: This kind of algorithm tends to change its routing decisions based on network topology or traffic load changes. The adaptive algorithm is also known as a dynamic routing algorithm. The three main types are as follows:
When do adaptive algorithms change their routing decisions?
Adaptive Algorithms – These are the algorithms which change their routing decisions whenever network topology or traffic load changes. The changes in routing decisions are reflected in the topology as well as traffic of the network.
How is the routing algorithm defined in OSPF?
This information forms a description of the network topology and the status of nodes, which defines the routing algorithm by calculating the shortest paths. The algorithm allows OSPF, from a node, to calculate the shortest path, with the constraints specified in the content associated with each link.
Which is the best path in a routing protocol?
The routing protocol is a routing algorithm that provides the best path from the source to the destination. The best path is the path that has the “least-cost path” from source to the destination.
