The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
Where there is a need for a great deal of analysis of network performance and security, switches may be connected between WAN routers as places for analytic modules. Some vendors provide firewall, [21] [22] network intrusion detection, [23] and performance analysis modules that can plug into switch ports. Some of these functions may be on ...
Viewing: Network data can be viewed in a graphical web-based frontend. Acknowledging: Users can interact with the software through the web-based frontend to acknowledge alarms or manipulate other notifications. Reporting: Specific reports on network data can be configured by the user and executed through the web-based frontend.
In a network using Open Systems Interconnection (OSI) architecture, the physical signaling sublayer is the portion of the physical layer that [7] [8] interfaces with the data link layer's medium access control (MAC) sublayer, performs symbol encoding, transmission, reception and decoding and, performs galvanic isolation.
The local network addresses used in IEEE 802 networks and FDDI networks are called MAC addresses; they are based on the addressing scheme that was used in early Ethernet implementations. A MAC address is intended as a unique serial number. MAC addresses are typically assigned to network interface hardware at the time of manufacture.
Network delay is a design and performance characteristic of a telecommunications network. It specifies the latency for a bit of data to travel across the network from one communication endpoint to another. Delay may differ slightly, depending on the location of the specific pair of communicating endpoints.

Combining can either occur such that multiple interfaces share one logical address (i.e. IP) or one physical address (i.e. MAC address), or it allows each interface to have its own address. The former requires that both ends of a link use the same aggregation method, but has performance advantages over the latter.
