Qoz analysis in multiprotocol label switching based viertual private network

الملخص EN

Multiprotocol Label Switching (MPLS) which combines the benefits of layer 2 switching with layer 3 routing and switching has helped us to construct a technology which combines the features of various VPN models.

Thus a new Technology called MPLS VPN was developed which results in simplified routing security and isolation among customers.

The rest of the paper is organized as follows, in section 2 and 3, an introduction to the MPLS Based VPNs is made and the various principle technologies that possibly build them are seen.

In section 4, a survey of the various existing QoS features of MPLS Based VPNs is made.

In section 5, an analytical approach to WFQ is made and how it is emulated from the GPS Model is seen.

The WF2Q model is also discussed.

In section 6, the QoS enhancement achieved when WF2Q scheduling model is used is seen.

Section 7, compares the and WF2Q model graphically.

Finally a summary of various QoS features has been made and QoS enhancements obtained using the WF2Q model is discussed.
