摘要： A method and system of providing physical port security in a digital data network is disclosed. The system keeps bit maps of allowed physical output ports for each physical network connection. The map of allowed ports can be different for different source addresses connected to the device. When digital data, such as an IP packet, is received, the appropriate physical port security bit map is retrieved and a logical AND is done on the physical port bit map generated by the destination information. The resulting bit map is used to determine which physical ports the data is routed to, blocking any requested destinations that are not appropriate destinations based on the port security bit map.

摘要： Certain aspects of a method and system for a power control based on application awareness in a packet network switch are provided. Data communication flow may be monitored in ports in a packet network switch based on packet classification. Ports where data flow is not detected may have at least some functionality disabled to reduce power consumption. In this regard, a power saving mode may be utilized for disabling at least some functionality in a switch port, such as Ethernet ports, for example. A partially disabled port may be fully enabled when monitoring detects active data communication flow in that port. Port functionality may be enabled or disabled sequentially, for example. In some instances, a physical layer portion of the packet network switch may be utilized to adjust power in a port based on the data communication flow.

摘要： Aspects of the invention utilize a secondary communication channel to conduct flow control at the word level. As a result, the overhead associated with flow control can be reduced, as well as the risk of buffer overflow. In one embodiment, embedded flow control information is encoded as reversed running disparity codes in each transmission lane. Additional control symbols may be coded by grouping a series of specially coded data words or inspecting a selected data word at regular intervals.
