ITEC 3210 Lecture Notes - Lecture 8: Customer-Premises Equipment, Packet Switching, Virtual Circuit
Document Summary
Services that provide transmission between remote networks, are offered by common carriers, common carriers are companies. Mans and wans are different in term of coverage, the geographical. Wan connects very long distance such as countries but mans, is municipal and not that large. One signing up for man or wan services is not responsible for infrastructure or maintenance but is responsible for customer premises equipment. Criteria for service: security, cost, availability, data rates, connection between locations. Categories: dedicated circuit networks, packet switched networks, virtual private networks. Errors in textbook: when they refer to reliability, they are not referring to reliability of piece of equipment, but they mean both availability and performance. It means that, it will be available and full ndr: when they refer to available, they mean particular service is offered in particular location, vpn not fully covered in text, recommendations are slightly different. Create dedicated and permanent point-to-point circuit between lans.
