	Topology Encyclopedia
		Topology (Greek topos, "place," and logos, "study") is a branch of mathematics that is an extension of geometry.
		The most basic division within topology is into point-set topology, which investigates such concepts as compactness, connectedness, countability, and algebraic topology, which investigates such concepts as homotopy, homology, and knot theory.
		In pointless topology one considers instead the lattice of open sets as the basic notion of the theory, while Grothendieck topologies are certain structures defined on arbitrary categories which allow the definition of sheaves on those categories, and with that the definition of quite general cohomology theories.

	Tracking Packet Flow Using Path Analysis
		Path Analysis is an operations and diagnostic application that traces the connectivity between two specified points on your network, including the physical and logical paths taken by packets flowing between those points.
		Path Analysis investigates and reports on Layer 3 and Layer 2 paths between a source and destination (Leg 3 in Figure 5-2).
		Path Analysis collects this information about Cisco devices that are SNMP-reachable and on non-Cisco routers as long as they are SNMP-reachable and are within a subnet that is known to be within the organizational domain.

	Path (topology) - Wikipedia, the free encyclopedia
		Note that a path is not just a subset of X which "looks like" a curve, it also includes a parametrization.
		Paths and loops are extremely important in branch of algebraic topology called homotopy theory.
		The equivalence class of a path f under this relation is called the homotopy class of f, often denoted [f].

	VISVIP paper for WebVIS'99
		We then adopted a spline representation: each subject path is depicted as a smooth curve overlaid on the directed graph.
		However, we found that the inherent topologies of the paths are also informative for discovering similarities and differences among subjects' navigation styles.
		Paths that looked complicated when laid out directly over a web site often revealed a much simpler structure when laid out according to their own topology (see Figure 5).

	Path (Site not responding. Last check: 2007-10-10)
		In graph theory a path is a sequence of vertices of a graph where there is an edge from any vertex in the sequence to the following vertex.
		In computing, path is the general form of a file or directory name.
		In topology, a path in a topological space X is a continuous function from the unit interval [0,1] into X.

	BGP
		Path attributes may also be used to distinguish between groups of routes to determine administrative preferences, allowing greater flexibility in determining route preference to achieve a variety of administrative ends.
		When sending routes to an external peer the local AS number is prepended to the AS path, hence routes received from an external peer are guaranteed to have the AS number of that peer at the start of the path.
		On external connections the AS path in unreachable announcements is set to the local AS, on internal connections the AS path is set to zero length.

		For multiple-path topology, the relationship between an FCP device and a channel using the FCP device must be described to iotab(4) beforehand.

	Roxen Community: RFC 2643 Cabletron's SecureFast VLAN Operational Model Version 1.8 (Informational)
		The switch flood path is formed using a spanning tree algorithm that provides a single path through the switch fabric that guarantees loop-free delivery to every other SFVLAN switch in the fabric.
		When both the call path and tap path pass through the switch, and the inport and outports of both connections are identical, the switch uses the existing call connection to route the tap.
		When both the call path and tap path pass through the switch, but the call path outport is different from the tap path outport, the switch enables an extra outport in either one or both directions of the call connection, depending on the direction of the tap.

	Network Layer Support for Overlay Networks
		Path Painting allows multiple end hosts to determine where their disparate paths to a rendezvous point meet, in order to facilitate overlay topology building.
		Path Painting: a new primitive for allowing end hosts to coordinate and learn where their individual paths to a rendezvous point converge, allowing efficient overlay topologies to be built.
		When another end host paints the same path, a notification is sent and the nodes may coordinate to graft the new end host to the overlay topology.

	UNINETT internweb: E2E topology and measurement thoughts
		We introduce the term path points to distinguish these measurements points from meters, that typically reside on the side of the path, but still monitor the path, or part of it.
		In essence, the topology is a graph of interconnected nodes.
		The detail and quality of the topology information may vary, ideally it should be a model of the running network.

	iPlane: An Information Plane for Distributed Services
		The path predictions are combined with measured characteristics of path segments to predict end-to-end path properties for a number of metrics such as latency, available bandwidth, and loss rate.
		To determine intersections between paths, we cluster interfaces that are owned by the same AS and reside in the same PoP, and deem two paths to have intersected if they pass through the same cluster.
		Once a path is predicted, iPlane simply composes the measured properties of the constituent path segments to predict the performance of the composite path.

	Amazon.com: Topology (2nd Edition): Books: James Munkres (Site not responding. Last check: 2007-10-10)
		I must say I was quite confused when I began the actual topology portion of the book (chapter 2), but this was due to the difficulty of topology, in general, and not the book itself.
		Unfortunately, this lack of a completely cohesive approach is unavoidable, since a course in point-set topology ought to provide a stepping stone one can use for further study in topology and not a mountain one can climb and conquer and thus know the subject completely.
		If you are searching for an introduction to point-set topology that will give you a solid grounding in the basics of point-set topology, but at the same time will give it to you in an easily approached manner, than this book is for you.

		Upstream Neighbor That switch attached to the inport of the switch flood path -- that is, the switch from which undirected messages are received.
		Downstream Neighbors Those switches attached to all outports of the switch flood path except the port on which the undirected message was received.
		Therefore, on each switch along the tap path, the tap connection is established in one of three ways: - The existing call connection is used with no modification.

	SeqQuest NEB Tutorial
		The forces on the ions are further modified such that the original forces parallel to the path and the inter-image spring forces perpendicular to the path are removed (this is the path "nudging").
		The saddle point geometry may be refined by using the climbing image method, which works by inverting the parallel force on images that are higher in energy than either of their neighbors.
		This method robustly finds a saddle point on a given path, given that there are sufficient images to describe the path topology.

	VLANs
		The Spanning-Tree Protocol allows multiple paths across switches and bridges while avoiding the pitfalls of switching loops.
		Topology information is sent through the network in bridge protocol data units (BPDUs) at steady intervals in order to keep the topology updated for every switch and bridge.
		The protocol is also advanced enough to survive changes in network topology and path or device failures.

	Method for Topology Independent Path Determination in Infiniband Subnets
		Disclosed is a method that uses algorithms and data structures for computing the optimal path between any two end-points, regardless of the topology of the Subnet.
		Since each switch in a path exacts a performance penalty, paths with fewer hops are generally preferable to those with more hops.
		The Subnet Object models the physical composition and topology of the Subnet. By following internal linkages in the Subnet Object, the disclosed method may determine the composition and physical interconnectedness of the subnet The construction and precise format of the Subnet Object are outside the scope of this disclosure.
