In 2019, Cisco registered a new URI scheme with the IANA called "pttp". This protocol is used as part of Packet Tracer 7.2.2 capabilities to transmit data between Packet Tracer and Cisco's CSR routing platform. [12] [13] As of mid-2022, little is known about this protocol or its functionality. [citation needed]
Cisco IOS XR Line card running IOS XR. IOS XR is a release train of Cisco Systems ' widely deployed Internetwork Operating System (IOS) , used on their high-end Network Convergence System (NCS) and carrier-grade routers such as the ASR 9000 series and Carrier Routing System series of routers.
The Cisco Nexus series switches are modular and fixed port network switches designed for the data center. Cisco Systems introduced the Nexus Series of switches on January 28, 2008. The first chassis in the Nexus 7000 family is a 10-slot chassis with two supervisor engine slots and eight I/O module slots at the front, as well as five crossbar ...
Bit value = 00 (0x00 to match above table type field bit order [2]) Indicate that the sender is ready to receive more data (cancels the effect of a previous RNR). Send this packet if you need to send a packet but have no I frame to send. A primary station can send this with the P-bit set to solicit data from a secondary station.
In digital communications networks, packet processing refers to the wide variety of algorithms that are applied to a packet of data or information as it moves through the various network elements of a communications network. With the increased performance of network interfaces, there is a corresponding need for faster packet processing.
Often the route a packet needs to take through a network is not immediately available. In that case, the packet is queued and waits until a link is free. The physical link technologies of packet networks typically limit the size of packets to a certain maximum transmission unit (MTU). A longer message may be fragmented before it is transferred ...
The current use of the IPv6 Traffic Class field divides this between a 6 bit Differentiated Services Code Point [34] and a 2-bit Explicit Congestion Notification field. [35] Extension headers carry options that are used for special treatment of a packet in the network, e.g., for routing, fragmentation, and for security using the IPsec framework.
A 64-bit interface identifier can be derived from the interface's 48-bit MAC address, although stable privacy addresses are now recommended as a default instead. [2] A MAC address 00-0C-29-0C-47-D5 is turned into a 64-bit EUI-64 by inserting FF-FE in the middle: 00-0C-29- FF-FE -0C-47-D5 .
