  21. Cisco VSG (虚拟安全网关)

  22. 虚拟安全网关的介绍 VM context aware rules Context aware Security Virtual Security Gateway (VSG) Zone based Controls Establish zones of trust Dynamic, Agile Policies follow vMotion Best-in-class Architecture Efficient, Fast, Scale-out SW Non-Disruptive Operations Security team manages security Virtual NetworkManagement Center(VNMC) Policy Based Administration Designed for Automation XML API, security profiles Central mgmt, scalable deployment, multi-tenancy

  23. 实现多层次安全 vSphere Tenant A Tenant B VDC vApp vApp vPath Nexus 1000V • Specify zoning policy with the appropriate granularity • Tenant • VDC • vApp

  24. VSG同物理设备的部署逻辑保持一致 VNMC VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM Nexus 1000V Distributed Virtual Switch vPath VSG Secure Segmentation (VLAN agnostic) Efficient Deployment (secure multiple hosts) Dynamic policy-based provisioning Log/Audit Transparent Insertion (topology agnostic) High Availability Mobility aware (policies follow vMotion)

  25. VSG 虚拟机到虚拟机的通信流程 1st packet Servers App Web servers VSG VM #8 VM #7 VM #6 VM #3 VM #4 VM #5 VM #2 VM #1 6 1 2 3 4 5 Service Data Path Nexus 1000 DVS • For the 1st packet within a network session, although the traffic redirection scheme is different, but the packet flow is similar. • Traffic redirection bases on Port-profile-to-VSG binding and flow entry lookup in the Service Data Path (SDP) • Processing of internet  VMs and Inter-VMs traffic are normalized. Different firewall policies will be applied to these traffic strictly based on source/destination attributes defined in the policy

  26. VSG 虚拟机到虚拟机的通信流程 2nd and subsequent packets App Servers Web Servers VSG VM #8 VM #7 VM #6 VM #4 VM #3 VM #5 VM #2 VM #1 4 1 2 3 Service Data Path Nexus 1000 DVS • After VSG has done the policy evaluation against the first packet of a network section, a flow-entry cache is established in SDP, which off-loads the processing of the rest of packets to SDP • The flow-lookup done in SDP would be able to identify the current state of the flow, thus SDP can process the subsequent packets based on the actions stored at the flow entry

  27. 总结 • 计算资源的虚拟化允许server做更多的工作 • 网络资源和计算资源的高度互动将大幅度提升数据中心的效率 • 统一网络服务提供了更大的弹性支撑
