  Information, Computer and Network Security Terms, Glossaries Dictionary - K
In cryptography, a key is a variable value that is applied using an algorithm to a string or block of unencrypted text to produce encrypted text, or to decrypt encrypted text.
Key Distribution is a process that delivers a cryptographic key from the location where it is generated to the locations where it is used in a cryptographic algorithm.
Key Recovery is a process for obtaining the value of a cryptographic key that previously was used to perform some cryptographic operation.

 What is Routing
Routing is the act of moving information across an internetwork from a source to a destination.
A routing domain generally is considered to be a portion of an internetwork under common administrative authority that is regulated by a particular set of administrative guidelines.
Routing algorithms must be robust, which means that they should perform correctly in the face of unusual or unforeseen circumstances, such as hardware failures, high load conditions, and incorrect implementations.

 CAIDA : funding : routing : atoms : proposal
We consider the routing protocol to be both the messages exchanged by the protocol and the basic algorithms of the routers that exchange these messages.
The effects of atom-based routing are similar to CIDR in that both are able to summarise prefixes (as aggregates and atoms respectively) and treat the summary as a unit.
Based on the destination IP address of the packet, the edge router tags the packet with the correct atom id. Based on the atom id, the packet is then forwarded by the system of internal routers (transit and edge routers) until it reaches the edge router where it leaves the island.

 Routing Summary
Routing is the function of choosing which computers a message should pass through on its way from source to destination.
Routing must be performed in large networks such as the Internet as well as in smaller networks such as within a university.
Static routing may be suitable for small local networks, but for a large global network, such as the Internet, dynamic routing is necessary to avoid overloading parts of the network.

 4.5. Route Selection
The routing cache is a hash table used for quick access to recently used routes.
If no matching entry is found in the specified routing table, the kernel will pass to the next rule in the RPDB, until it finds a match or falls through the end of the RPDB and all consulted routing tables.
Failing a route lookup in the main routing table the final rule (32767) instructs the kernel to perform a route lookup in table 253.

 Key based routing - Wikipedia, the free encyclopedia
Key based routing (KBR) is a lookup method used in conjunction with distributed hash tables (DHTs).
This may not necessarily be defined as physical distance, but rather the number of network hops.
KBR improves the efficiency of decentralized information retrieval in peer-to-peer networks.

 Existing Routing Protocols and IPv6
Various routing protocols have been developed over the years to deal with the various types of routing problem domains, ranging from internal routing protocols (routing within an autonomous system) to external routing protocols (routing between different autonomous systems).
The current routing protocols are adequate for the current version of the IP protocol (IPv4), but they are not without their problems, the largest of which is the explosion in routing table size caused by the unforeseen growth of the Internet.
An "autonomous system" in routing terms is a collection of networks that is administered as a whole by a single specific administrator, or in less vague terms, a collection of networks (and/or hosts) that are all connected to each other and which can communicate with each other without resorting to routing outside the autonomous system.

 Overcoming Asymmetric Routing on Multi-Homed Servers
Asymmetric routing is a commonly unanticipated outcome of this configuration that comes about because traditional routing is wholly destination-based.
This simple approach, which relies heavily on a single default route, results in a concentration of outgoing traffic through a single interface without regard to the interface through which the request originally was received.
The key difference in an iproute2 world is the system may contain many different destination-based routing tables instead of a single global system table.

This schedule is based upon the specification of the flange you use to start the route.
Answer : A route point is used to locate a fitting at an endpoint, such as a flange, or at an intersection, such as a tee or a cross, in your 3D sketch.
Edit your route, drag and drop the eccentric reducer to the end of the 3D sketch segment and choose the alignment (smaller/larger end) using the Tab key.

 Motorola IP Solutions - Edge Routing
The design of the BSR 64000 is based on centralized routing and distributed forwarding and provides the benefits of simple configuration (single router appearance), scalable performance (each additional line card brings an associated forwarding engine), and low cost-of-entry (operators only purchase the forwarding power required).
The key to successful implementation is to add intelligence to the edge of the network so operators can support multiple business and residential services.
With the BSR 64000, providers benefit from carrier-class routing and can scale their networks in terms of numbers of routes, interfaces, and peering relationships.

 Advanced routing mini-HOWTO
Routing table is scanned by kernel from top to bottom, when destination is found within some network (or there is special "host" entry for it) packet is forwarded to the specified gateway via corresponding interface.
Static and default routes from this example may have been also put to any other table which is looked up after table main (with preference greater than 32766).
You should be extremely careful playing with NAT, even in a network with complex topology, routed by routing protocols or simply connected to other network through more than one router.

 What is routing? - A Word Definition From the Webopedia Computer Dictionary
Routing is usually performed by a dedicated device called a router.
Routing is a key feature of the Internet because it enables messages to pass from one computer to another and eventually reach the target machine.
The principal difference between the two is that bridging occurs at a lower level and is therefore more of a hardware function whereas routing occurs at a higher level where the software component is more important.

 Library » White Papers :: Ixia - Leader in IP Performance Testing
MPLS is based on the concept of label switching: an independent and unique label is added to each data packet and this label is used to switch and route the packet through the network.
In the case of hop-by-hop routing, MPLS uses the network topology information distributed by traditional Interior Gateway Protocols (IGPs) routing protocols such as OSPF or IS-IS. This process is similar to traditional routing in IP networks, and the LSPs follow the routes the IGPs dictate.
Given the advances in hardware-based routing in recent years, the expectations for device performance have grown so that line rate traffic support is typically a given.

 Name-based Routing
At the inter-realm level, routing relays use name-based routing because addresses are not a meaningful way to identify endpoints in the wide area, and to ensure the availability of those names.
The key challenge with a name-based routing is maintaining the routing database efficiently even in the presence of names that do not match the routing hierarchy.
All names in a routing aggregate may be treated identically in routing calculations, thus reducing load at relay agents.

 TV-Free.ORG - Free Internet TV - Peer to Peer File Sharing P2P ( Cybersky-TV, Cool Streaming, DemoTV )
As each node passes a document to its neighbor, it does not know or care whether its neighbor is just another routing node forwarding information on behalf of another, whether it is the source of the document being passed, or whether it is a user node that will present the document to an end user.
If the document is not found in the local data store, the node then finds the node in its routing table that it thinks will be able to locate the key most quickly, and forwards the request to that node, remembering that it has done so.
The old behavior was to remember which keys were retrieved from what nodes, and to route based on which node gave us the key closest to the one we were looking for.

 Security Assumptions and Key Setup
To set up authentic public keys, we can either embed all public keys at initialization in each node, or assume a PKI and embed the trusted Certification Authority's public key in each node and then use that key to authenticate the public keys of other nodes.
We assume for this a trusted Key Distribution Center (KDC) that either shares a secret key with each node, or uses its private or TESLA key to broadcast authenticated public keys of nodes.
To bootstrap authenticated keys between pairs of nodes, the KDC node initiates a Route Discovery with a special, reserved address (not the address of any actual node) as the target of the Discovery.
