Some embodiments of the invention provide a method for monitoring and adjusting a service chain that includes several services to perform on data messages passing through a network. For a service chain implemented by a set of service paths each of which includes several service nodes that implement the services of the service chain, the method receives, from a set of service proxies, operational data relating to data transmission characteristics of a set of operational service nodes. The method analyzes the data transmission characteristics. In response to the analysis of the data transmission characteristics, the method alters the set of service paths implementing the service chain.

Method of adjusting service function chains to improve network performance

A novel method of providing virtual private access to a software defined data center (SDDC) is provided. The SDDC uses distributed VPN tunneling to allow external access to application services hosted in the SDDC. The SDDC includes host machines for providing computing and networking resources and a VPN gateway for providing external access to those resources. The host machines that host the VMs running the applications that VPN clients are interested in connecting performs the VPN encryption and decryption. The VPN gateway does not perform any encryption and decryption operations. The packet structure is such that the VPN gateway can read the IP address of the VM without decrypting the packet.

Distributed tunneling for VPN

Some embodiments of the invention provide a method for monitoring a particular service chain that includes several services to perform on data messages passing through a network. The method provides a user interface to receive a selection of the particular service chain from a plurality of service chains. The particular service chain is implemented by several service paths, each of which includes several service nodes that implement the services of the service chain. The method generates a graphical display of the service paths through the service nodes, and as part of this graphical display, provides operational data relating to operations of the service nodes of the service paths. In some embodiments, the method also provides, as part of the graphical display, operational data relating to operations of individual service path.
