    摘要: An architecture, arrangement, system, and method for providing service access in a data center are disclosed. In one embodiment, an arrangement can include: an aggregation switch configured to transfer data between a network and an access layer; and service modules coupled to the aggregation switch, where each service module is configured to provide a service for the data when selected. The service modules can include: firewall, load balancer, secure sockets layer (SSL) offloader, intrusion detection system (IDS), and cache, for example. Further, the service selection can be substantially transparent to an associated server.

    摘要: An architecture, arrangement, system, and method for or controlling traffic flow into and out of a server farm having active-active stateful devices. A symmetric Gateway Load Balancing Protocol (sGLBP) eliminates asymmetric traffic flow for out-bound traffic. Load distribution for in-bound traffic is balanced between a redundant pair of aggregation switches using either static host routes, Route Health Injection or in a more general manner, with external routes with a mask longer than the connected subnet advertised by the routing protocol. The return traffic is symmetric because it returns through the same aggregation switch that it came from. Similarly, traffic originating from a server farm exits from one of the redundant aggregation switches and returns from the same aggregation switch.

    摘要: A data center provides secure handling of HTTPS traffic using backend SSL decryption and encryption in combination with a load balancer such as a content switch. The load balancer detects HTTPS traffic and redirects it to an SSL offloading device for decryption and return to the load balancer. The load balancer then uses the clear text traffic for load balancing purposes before it redirects the traffic back to the SSL offloading device for re-encryption. Thereafter, the re-encrypted traffic is sent to the destination servers in the data center. In one embodiment, the combination with the back-end SSL with an intrusion detection system improves security by performing intrusion detection on the decrypted HTTPS traffic.

    摘要: A data-center network architecture. The data-center network architecture incorporates a front end having an aggregation layer exhibiting integrated service-module intelligence. A server farm connects the front end with a storage network. In a specific embodiment, the aggregation layer includes plural interconnected multilayer switches incorporating service-module intelligence implemented via one or more service modules. Plural layer-2 switches communicate with the plural multilayer switches. The server farm includes one or more servers that are dual homed or multihomed with the plural layer-2 switches. The storage network includes plural interconnected multilayer directors and one or more Fibre Channel hosts using Host Bus Adapters (HBAs) that interface one or more data-storage devices to the server farm.

    摘要: An intrusion detection system (IDS) is capable of identifying the source of traffic, filtering the traffic to classify it as either safe or suspect and then applying sophisticated detection techniques such as stateful pattern recognition, protocol parsing, heuristic detection or anomaly detection either singularly or in combination based on the traffic type. In a network environment, each traffic source is provided with at least one IDS sensor that is dedicated to monitoring a specific type of traffic such as RPC, HTTP, SMTP, DNS, or others. Traffic from each traffic source is filtered to remove known safe traffic to improve efficiency and increase accuracy by keeping each IDS sensor focused on a specific traffic type.

    摘要: A one-arm data center topology routes traffic between internal sub-nets and between a sub-net and an outside network through a common chain of services. The data center topology employs layer 4 services on a common chassis or platform to provide routing and firewall services while reducing the number of devices necessary to implement the data center and simplifying configuration. Load balancing is provided by a load balancing device. In the one-arm topology, policy based routing or client network address translations or NAT pushes traffic to the CSM.
