Social Networks, Drug Injectors' Lives, and HIV AIDS (Aids Prevention and Mental Health)

Social Networks, Drug Injectors' Lives, and HIV/AIDS acknowledges HIV as a socially based disorder - its transmission frequently calls for intimate touch among participants - and exhibits how social networks form high-risk behaviors and the unfold of HIV. The authors recount the groundbreaking use of social community tools, ethnographic direct-observation ideas, and in-depth interviews in their research of a drug-using neighborhood in Brooklyn, manhattan.

Which routing protocol runs between the customer and the service provider in an overlay VPN? ■ Which routers are routing protocol neighbors of a CE-router in overlay VPN? ■ List three IP-based overlay VPN technologies. ■ What is the major benefit of peer-to-peer VPN as compared to overlay VPN? ■ List two traditional peer-to-peer VPN implementations? ■ What is the drawback of all traditional peer-to-peer VPN implementations? Advanced MPLS VPN Solutions Copyright  2000, Cisco Systems, Inc. Major VPN Topologies Objectives Upon completion of this section, you will be able to perform the following tasks: ■ Identify the three major categorizations of VPN ■ Identify the three Overlay VPN topologies ■ Understand the implications of using overlay VPN approach with each topology ■ List sample usage scenarios for each topology ■ Identify the three VPN categorization based on business needs ■ Identify the three VPN categorization based on connectivity needs VPN Categorizations There are three major VPN categorizations: ■ Topology categorization, which only applies to overlay VPNs ■ Business categorization, which categorizes VPNs based on the business needs they fulfill ■ Connectivity categorization, which classifies VPNs based on their connectivity requirements.

Com Page33 The hub-and-spoke topology is the simplest overlay VPN topology – all remote sites are linked with a single virtual circuit to a central CE-router. The routing is also extremely simple – static routing or distance-vector protocol like RIP are more than adequate. If you are using dynamic routing protocol like RIP, splithorizon must be disabled at the hub router, or you must use point-to-point subinterfaces at the hub router to overcome the split-horizon problem.

MPLS VPN Technology 2-37 Summary There are three major categorizations of Virtual Private networks: ■ Topology categorization, which classifies the VPNs based on the topology of point-to-point connections in overlay VPN implementation ■ Business categorization, which classifies VPNs into Intranets, Extranets and niche solutions like Virtual Private Dialup Networks ■ Connectivity categorization, which classifies VPNs based on the connectivity needs. The topology categorization ranges VPNs from full mesh, where there is a direct virtual circuit between any two sites, to partial mesh, which is built based on a number of constraints (traffic patterns and cost being the most important of them) and finally hub-and-spoke where a central site acts as the transit point between all spoke sites.
