  40. Virtual Path (VP)SwitchingVsVirtual Connection (VC)Switching

  41. ATM NIM ONT #1 STM-1 PON 1/37 ONT #2 1/275 4/62 7/152 ONT #3 ONT #4 VP Switching Versus VC SwitchingVC Switching • In VC Switching, each connection is switched through the network as a completely independent entity • This results in, potentially, hundreds or thousands of separate connections on the ATM interface • Each VC is assigned its own unique combination of Virtual Path Identifier (VPI) and Virtual Connection Identifier (VCI)

  42. ATM NIM ONT #1 STM-1 PON ONT #2 1/37 VPI=1 1/275 1/62 1/152 ONT #3 ONT #4 VP Switching Versus VC SwitchingVP Switching • In VP Switching, a Path, or “pipe,” is created with a specific set of characteristics. This VP is assigned a specific VPI • Connections mapped to that ATM interface with the same VPI are “bundled” into that VP and are carried from point to point as a single connection • Each VC within the VP has a unique Virtual Connection Identifier (VCI)

  43. ATM NIM ONT #1 STM-1 PON ONT #2 1/37 VPI=1 1/275 1/62 1/152 ONT #3 ONT #4 VP Switching Versus VC SwitchingVP Switching • Each VP is counted as only 1 connectionno matter how many VCs are in the VP • VP Switching is also known as VC Tunneling

  44. VP Switching Versus VC SwitchingVC Switching • VP Switching and VC Switching occur in a logical switching environment between two ATM interfaces • In the Terawave PON environment, all ATM NIM cards perform VC Switching by default • VP or VC Switching is performed between the following cards: • ATM NIM to ATM NIM on the OLT • ATM NIM on the OLT to DS-3c SIM on the ONT • OC-3c and STM-1 ATM NIMs can perform VP Switching and VC Switching, but not both at the same time • OC-12c and STM-4c ATM NIMs can perform VP Switching and VC Switching at the same time

  45. VP Switching Versus VC SwitchingWhy Is It Important To Know This? • There is a connection limit on each card in the network. This means that you can only make a certain number of connections across that card • This is normally not an issue, but under the right circumstances, this could be critical information • Those networks that use DS-3c SIM cards as the PON access point for DSLAMs fall in this category of circumstances
