	Routing - Wikipedia, the free encyclopedia
		Routing directs forwarding, the passing of logically addressed packets from their source network, toward their ultimate destination through intermediary nodes; typically hardware devices called routers.
		Routing differs from bridging in its assumption that address-structures imply the proximity of similar addresses within the network, thus allowing a single routing-table entry to represent the route to a group of addresses.
		Routed protocol ;: Any network protocol that provides enough information in its network layer address to allow a packet to be forwarded from one host to another host based on the addressing scheme, without knowing the entire path from source to destination.

	[No title]
		In the normal case where all entities on a given network are considered to be the same, d(i,j) is the same for all destinations on a given network, and represents the cost of using that network.
		Routes to subnets will be meaningless outside the network, and must be omitted if the destination is not on the same subnetted network; they should be Hedrick [Page 30] RFC 1058 Routing Information Protocol June 1988 replaced with a single route to the network of which the subnets are a part.
		If the gateway for the route is on the network for which the datagram is being prepared, the metric in the entry is set to 16, or the entire entry is omitted.

	Programmable Virtual Network Routing
		The network entities studied by this project are the following: the Virtual Network Server, which provides routing and packet forwarding capabilities; the Virtual Network Manager, which facilitates network deployment and management; the Virtual Network Client, which encapsulates and exchanges IP packets with peers in virtual networks.
		A destination is an address in the router's network space, and each gateway is an address in the network space of the router's parent.
		Failure of routing to 192.168.2.2 and 192.168.7.4 is normal because micro2 is not a participant of these networks.

	Routing Overview
		Static routing algorithms are hardly algorithms at all, but are table mappings established by the network administrator prior to the beginning of routing.
		A common implementation of this is using a route to Null0 with an administrative distance of 250 to simply hold a route until another routing protocol with a higher administrative distance overrides the route.
		Route announcements that do not coincide with a registered route or are not registered with the RADB will not be visible to most of the Internet.

	IBM System Network Architecture (SNA) Routing
		Explicit routes are the physical connections between two subarea nodes, and they serve as the ordered sequences of subareas and connecting transmission groups.
		Virtual routes include values defining transmission priority and global flow control, which is provided by pacing, in which a receiver with sufficient buffer space grants pacing windows to the sender.
		IBM Advanced Peer-to-Peer Networking (APPN) routing is dynamic and is based on a least-weight path calculated from input received from all APPN network nodes.

	Network routing
		As in the case of a queueing network, it is possible to define a shadow price for a link, but this now depends not just upon the traffic statistics for the link but also upon the shadow prices of adjacent other links within the network.
		This indicates the importance of treating a network as a whole: the apparent local benefits of a capacity or routing change may be completely negated by adverse consequences elsewhere in the network.
		The routing scheme described in Section 5 has the advantage that it makes no special assumptions about the underlying topology of the network, but it is adaptive rather than dynamic.

	Cobalt Multimedia Dedicated Servers - Network Routing
		Instead, routing information received from peer routers is retained until an incremental update is received.
		Similarly, when the routing table changes, routers send the portion of their routing table that has changed.
		When one of our providers has network issues which may cause connections to slow down, we route your customers to the fastest available connection, to ensure maximum connection speed and virtually eliminate down time.

	HIERARCHICAL NETWORK ROUTING
		Area routing schemes (when destination names are structured corresponding to the network topology) allow nodes to reduce the size of routing tables, by recording only one entry for an entire region rather than one for each node in the region.
		We describe a general hierarchical routing scheme that allows all nodes to participate in a distributed routing network, using close to optimal paths, with short routing tables, and a reduction of topology information for minor nodes.
		When the network starts, the local details are automatically propagated within the visible region, and the nearest neighbors supply sufficient topology information for the new node to route messages to the rest of the network.

	Routing in the Internet
		Routing is the technique by which data finds its way from one host computer to another.
		It is necessary to encapsulate the IP datagram within whatever frame format is in use on the local network or networks to which the computer is attached.
		The host operation is to first look for the destination address as a host address in the routing table, if it is not found then look for the destination net address in the routing table and if that is not found then use one of the default addresses (there may be several).

	Onion Routing
		Onion Routing prevents the transport medium from knowing who is communicating with whom -- the network knows only that communication is taking place.
		The protection of Onion Routing is independent of whether the identity of the initiator of a connection (the sender) is hidden from the responder of the connection, or vice versa.
		In an attempt to maximize coherence between these as well as to follow good mathematical practice, we will consider the initial 1996 design to be generation 0; all design elements after that and before Tor are generation 1; and Tor, at least as conceived roughly 2002--2005, is generation 2.

	Developing an Effective Routing Network
		However, as I suggested earlier, a big part of implementing a truly redundant network is to make the functional routers recognize that a failure has occurred and to be able to respond to that failure by rerouting the traffic through the links that are still functional.
		Although distance vector routing also supports static routes, the general idea behind distance vector routing is that the routers build their internal routing tables based on information that they’ve received from other routers on the network.
		The routers on these networks, in turn, pass the routing information on to other networks that they are connected to, until the entire organization has been made aware of the failure.

	Howstuffworks "How Routing Algorithms Work"
		When we say "best route," we consider parameters like the number of hops (the trip a packet takes from one router or intermediate point to another in the network), time delay and communication cost of packet transmission.
		In decentralized routing algorithms, each router has information about the routers it is directly connected to -- it doesn't know about every router in the network.
		When C receives B's routing table, it sees that B has changed the weight of its link to A from 1 to 3, so C updates its table and changes the weight of the link to A to 4 (1 for C to B, and 3 for B to A, as B said).

	Network Routing Basics
		For example, 192.168.200.83 and 192.168.201.35 are on separate networks if the netmask is 255.255.255.0 (a class C netmask).
		Note that we are saying our route goes to 192.168.201.0, not to a specific address: the.0 says we're giving a route to the whole network.
		Lets say you have two cards: your internal network card which is 192.168.2.10 with a mask of 255.255.255.0, and your external card which gets a DHCP address that's real, but let's pretend that right this minute it's 64.xxx,xxx.12 again with a 255.255.255.0 mask.

	RouteScience's PathControl
		The BGP routing algorithm computed by an Internet router determines the best egress route by comparing default attributes in a specific order for each route, from each provider, until a best path can be determined.
		In a situation in which all the metrics are identical, the best path selected is the route with the lowest BGP router identification number.
		When the latency and packet loss were removed from the network, PathControl adjusted the preferred route back to the original default egress path on the Cisco 7206 router.
