ISP Information:
This is created when a bunch of physically connected ports are grouped together by network hardware that supports VLANs. These VLANs are each treated as completely separate entities, and can only be joined together by a router. This scheme is useful for grouping departments together for security and minimizing network traffic.
ISP Glossary:
VLAN - In article ,TELECOM Digest Editor wrote: All day Sunday and Monday on television and radio news have been these *horrible* reports of several fires burning out of control throughout the San Diego and Los Angeles area. Apparently the fires go along and burn down a few houses, then jump the road and burn houses on the other side as well. Here and there the fires skip a few houses entirely. On the television news today they showed two or three totally burned to the ground houses next to each other, nothing left at all, then the next house was standing there okay, green grass in the front yard, no sign of any damage at all. Then next to that another burned out house.It's not as bad as the television news shows. Despite the severalhundred thousand homes that have been threatened, only a thousand orso have been destroyed so far, with another thousand or so damaged.And that is compared with the millions of homes and the 20 or somillion people in the Los Angeles and San Diego metropolitan areas.Almost all of the damage has been confined to the foothills, and whilethere has been concern of fires in the Simi Valley region burning landto the sea, that is a remote possibility at this point, barring newfires starting on the path. In the Oakland fire, ten years ago, therewas a serious concern that the fire would burn west all the way downto the bay, impacting several hundred thousand people over arelatively confined area.By contrast, the wildfires in Southern California are spread out andare in suburban areas, although there are some commercial areas in SanDiego that are threatened. San Diego is the worst hit of the areas hitby the fire. It must be really causing a lot of havac out there not only on wireline telephone service, but also wireless and cable systems. Can anyone there in southern California (still connected to the internet?) give us any reports on this? I tried twice to call someone I know in the 714 area code and a recording told me 'service is unavailable right now due to emergency conditions.' We all know that many areas of the west coast have problems with forest fires, but isn't this one sort of outrageous?I'm out in the 909 area code and have had no problems reaching anyone,even people who are in the evacuation area (but not burned). Thenetwork seems to be acting fine here, although there might be concernsin San Diego.Hank Fung fungus@ocf.berkeley.edu
