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.
The majority of HIV researchers agree that HIV evolved at some point from the closely related Simian immunodeficiency virus (SIV), and that SIV or HIV (post mutation) was transferred from non-human primates to humans in the recent past (as a type of zoonosis).he authors proposed that HIV-1 originated in the area of French Equatorial Africa in the early 20th century (when the colonial abuses and forced labor were at their peak). Later researches proved these predictions mostly correct: HIV-1 groups M and O started to spread in humans in late 19thâearly 20th century.
