Abstract: Techniques are disclosed for providing remote access to virtual machine (VM) serial port interfaces of cloud applications through automated serial port concentration techniques. A coordination agent can be deployed, and a virtual serial port concentrator (VSPC) module can be deployed along with VMs of a cloud application. The coordination agent can determine that the cloud application has entered a running state, determine an IP address of the VSPC module, and cause a serial port interface of each VM to be coupled with the VSPC module. The VSPC module can allocate local ports for the VMs and report the port numbers to the coordination agent to be provided to a client. The client can transmit data for a serial port connection to a particular VM through the VSPC module by sending the traffic to the IP address of the VSPC module at a particular port associated with the particular VM.

Abstract: A traffic simulator for a cellular radio telecommunications network. The traffic simulator includes a function handler which generates a plurality of basic call functions performed by mobile stations (MSs) over an air interface link with the network. A sequence handler utilizes the basic functions to generate a plurality of call sequences, and a traffic mix handler utilizes the plurality of call sequences to generate an overall traffic mix. A MS handler includes a plurality of MS state machines for different types of MSs and a database of MS properties. The MS handler interfaces with the basic functions to generate realistic inputs to the sequence handler. A cells handler includes a database of cells in the network and parameters relating to radio conditions. The cells handler also interfaces with the basic functions to generate realistic inputs to the sequence handler. A traffic repository may inject recorded real mobile station traffic into the traffic mix.
