The Core

Network topology is the core of configuration management and the infrastructure of resource management.And it is based on the detection of a network failure and the analysis of network performance.This requires the network topology complete, accurate and friendly interface with visualization.This article describes the classification of the physical network topology discovery.Based on Bridge-MIB and MIB-II of SNMP devices, designed topology discovery algorithm in data link layer and network layer.Test results show that the algorithm can accurately find the device and connection on the network layer and the data link layer.

Data Link Layer

Routing uses a unique identifier of each participating node in the network to forward the information between two nodes. Traditionally, routing takes place at the network layer of a standard network layering architecture where it takes into account the local or the global network information, albeit, the local information uses a local-scope unique identifier. One of the prime objectives of any routing strategy at the network layer is to forward data from one end to another; however, the same objective can also be achieved at the data link layer by using the hardware address of each node as a unique identifier. This chapter discusses the key questions. (i.e., Why traditional routing is called IP-based routing? What if we reorient the traditional concept of routing on the data link layer? What are the positive and negative impact, to carry out routing at IP—or data link—layer?) This study may be helpful for researchers to understand the concept of IP-based routing and path selection at link layer regardless of the standard layering architecture and the type of IP address.
