ATM Layer: Virtual Circuits
{"Image DocumentName": "ATM Layer: Virtual Circuits", "Image ImageDescription": "VC transport: cells carried on VC from source to dest. call setup, teardown for each call before data can flow. each packet carries VC identifier (not destination ID) every switch on source-dest path maintain state for each passing connection. link,switch resources (bandwidth, buffers) may be allocated to VC: to get circuit-like perf. Permanent VCs (PVCs) long lasting connections. typically: permanent route between to IP routers. Switched VCs (SVC): dynamically set up on per-call basis. 5: DataLink Layer.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
