This MIB module defines objects for network and system information of Global Server Load Balancer(GSLB) as a network device. A GSLB device is used to allocate the least-loaded and proximate resource to the requester. The MIB objects define information about GLSB status, GSLB's peers (other GSLB devices available on its network with which it interacts) information & status, GSLB's proximity information related statistics, etc. Further it defines related notifications. Acronyms and their description: DNS : Domain Name Service (RFC1035). D-proxy : Local DNS name server of the client. Proximity : Refers to the distance or delay, in terms of network topology and not geographic distance, between the requesting client's D-proxy and the resources corresponding to that request. Proximity : To respond to DNS requests with the most probing proximate answers, the GSLB device communicates with a probing device located in each proximity zone to gather round-trip time (RTT) metric information measured between the requesting client's D-proxy and the zone. The GSLB device then directs client requests to an available resource with the lowest RTT value. Probed : This is the device to which the GSLB device device sends a proximity probe. This is done to learn the proximity of the device. DRP : Director Response Protocol (DRP) is a simple User Datagram Protocol (UDP) based application developed by Cisco Systems, Inc. DRP enables Cisco Distributed-Director product to perform global load distribution and content routing in a sophisticated manner that accounts for server availability, relative client-to-server topological proximities, and client-to-server link latency to determine the best server. Using routing table intelligence in the network infrastructure, Distributed-Director transparently redirects end-user service requests to the closest server, as determined by client-to-server topological proximity or client-to-server link latency, resulting in increased access performance seen by the end user. Region : Higher-level geographical groupings that may contain one or more locations. Each location should be assigned to a region. Location : Grouping for devices with common geographical attributes. A location is assigned to a region. A location is also assigned to a zone, which is used for proximity probing. Zone : A network can be logically partioned into zones based on the arrangement of devices and network partion characteristics. A zone can be geographically related to data centers in a continent, a country, or a major city. All devices, such as web servers in a data center, that are located in the same zone have the same proximity value when communicating with other areas of the Internet. Within each zone, there is an active probing device that is configured to accept probing instructions from any GSLB device. Probing here refers to the process of measuring RTT from one probing device to a requesting D-proxy.
