VPLS is becoming a popular networking option. Its inherent Ethernet any-to-any connectivity model makes VPLS a popular choice for enterprises adding or deleting sites. Existing Ethernet users may have a simple implementation by modifying existing Ethernet equipment, which will also scale easily to meet future bandwidth needs.
HIV is an abbreviation for Human Immunodeficiency Virus. There are two main forms of HIV: HIV-1 and HIV-2. HIV-1 was discovered by Luc Montagnier and his associates at the Institute Pasteur in Paris in 1983.ince its discovery in 1983, no new modes of transmission of HIV have been discovered. HIV cannot be transmitted by touch, by insect vectors, or across fomites. Currently, blood supplies are screened for hepatitis, HIV, and other infections.
Discovery of HIV. From the earliest reports of a new disease, scientists around the world focused their efforts on finding the cause of AIDS. They circulated information informally; they held meetings to exchange ideas; and they published promising findings. A pioneer in this effort was Dr. Robert Gallo of the National Cancer Institute, who only recently had discovered the first two human retroviruses, HTLV-I and HTLV-II.
