         Multi-Service Virtualization Using Virtual Line Cards
               draft-wang-msv-using-virtual-line-card-00

Abstract

   There are many example procedures in our mind which can benefit from
   the service virtualization and the service pooling.  Therefore, we
   come up with this idea of multi-service virtualization, not only
   supports service resource pooling to realize intelligent resource
   sharing, but also makes the service much more flexible and reliable.

1.  Introduction

   A growing tendency is that serious kinds of services such as security
   (e.g., FW, AV) have to be deployed simultaneously.  Both the inline
   and bypass disposition pattern of traditional network pose great
   challenges in this situation, e.g., difficulty with planning safety
   path, fragmentation in security employment, complexity of bypass
   deployment, and so on.  At the same time, physical line cards expose
   significant shortcomings in practical use, such as scalability issue,
   lack of flexibility and reliability, et., al.  In this context, we
   introduce an idea of multi-service virtualization, not only supports
   service resource pooling to realize intelligent resource sharing, but
   also makes the service much more flexible and reliable.
