In a network based on packet switching, processing delay is the time it takes routers to process the packet header. Processing delay is a key component in network delay. During processing of a packet, routers may check for bit-level errors in the packet that occurred during transmission as well as determining where the packet's next destination is.
The C10k problem is the problem of optimizing network sockets to handle a large number of clients at the same time. [1] The name C10k is a numeronym for concurrently handling ten thousand connections. [2]
Graphical depiction of contributions to network delay. 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. [1] [2]: 5 It is typically measured in multiples or fractions of a second. Delay may ...
In network calculus, a flow is modelled as cumulative functions A, where A(t) represents the amount of data (number of bits for example) sent by the flow in the interval [0,t). Such functions are non-negative and non-decreasing. The time domain is often the set of non negative reals. Arrival and departure curve at ingress and egress of a server.
Access time is the time delay or latency between a requested access attempt and successful access being completed. In a telecommunications system, access time values are measured only on access attempts that result in successful access. Access failure can be the result of access outage, user blocking, incorrect access, or access denial.
Processing delay (the time taken to process a packet in a network node) Queuing delay (the time a packet waits in a queue until it can be transmitted) Transmission delay (the amount of time necessary to push all the packet into the wire) Propagation delay (amount of time it takes the signal’s header to travel from the sender to the receiver)
The round-trip time or ping time is the time from the start of the transmission from the sending node until a response (for example an ACK packet or ping ICMP response) is received at the same node. It is affected by packet delivery time as well as the data processing delay , which depends on the load on the responding node.
Access time is the time delay or latency between a request to an electronic system, and the access being initiated or the requested data returned.. In computer and software systems, it is the time interval between the point where an instruction control unit initiates a call to retrieve data or a request to store data, and the point at which delivery of the data is completed or the storage is ...
