Idea of “The IEEE standardized protocol”-Part-10


IEEE standardized

Spanning Tree Protocol :

 A bridge protocol that uses the Spanning Tree algorithm,allowing alearning bridge to dynamically work around loops in a network topology by creating a spanning tree.Bridges exchange bridge protocol data unit (BPDU)messages with other bridges to detect loops and then remove the loops by shutting down selected bridge interfaces.Refers to both the IEEE 802.1d Spanning Tree Protocol standard and the earlier Digital Equipment Corporation Spanning Tree Protocol upon which it is based.The IEEE version supports bridge domains and allows the bridge to construct a loop-free topology across an extended LAN.The IEEE version generally is preferred over the Digital version.

Split horizon :

A routing technique in which information about routes is prevented from exiting the router interface through which that information was received.Split-horizon updates are useful in preventing touting loops.

Subinterface :

One of the virtual interfaces on a single physical interface.

Subnet :

Subnets are subdivisions of a Class A,B,or C network,as configured by a network administrator.Subnets allow a single  Class A,B,or C network to be used and still allow for a large number of groups of IP addresses,as a required for efficient IP routing.

Subnet broadcast address :

The same as a broadcast address.

Subnet mask  :

A 32-bit address mask used to indicate the bits of an IP address  that are being used for the subnet part of the address.Sometime simply called a mask.

Successor :

In EIGRP,a neighboring router that could possibly be an alternative next-hop router to reach a particular subnet.Successor might or might not be feasible successors.

SVC  :

Switch Virtual Circuit.A VC that is set up dynamically when needed.An SVC can be equated to a dial connection in concept.
