Destination port– The port of the device receiving the data. UDP port numbers can be between 0 and 65,535. Length– Specifies the number of bytes comprising the UDP header and the UDP payload data. The limit for the UDP length field is determined by the underlying IP protocol used to tr...
On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed and some of the older MIB structures are defined in theIpmib.hheader file not in theIprtrmib.hheader file. Note that theIpmib.hheader file is automatica...
It means that TCP requires connection prior to the communication, but the UDP does not require any connection. Reliability TCP is a reliable protocol as it provides assurance for the delivery of the data. It follows the acknowledgment mechanism. In this mechanism, the sender receives the ...
the size of packets can vary depending on the network protocol and the data being transmitted. however, in most cases, packets are limited to a maximum size to ensure efficient transmission. for example, the maximum size of an ethernet packet is typically around 1500 bytes. what happens if a...
It should be 4 bytes or none at all. Is UDP suitable for my needs? 2) Is there a "minimum packet size" for UDP? In other words, when my client sends a payload of 4 bytes to the server, are there actually more bytes going across the wire due to a minimum packet size? I'm ...
SNMPv1 is the initial version of SNMP and provides the minimum network management functions. SNMPv1 provides authentication based on community names, causing low security. In addition, a limited number of error codes are returned in packets. SNMPv2c also provides authentication based on community name...
Window size TCP checksum– The sender generates a checksum and transmits it in every packet header. The receiving device can use the checksum to check for errors in the received header and payload. Urgent pointer– If URG control flag is set, this value indicates an offset from the sequence...
You can create CloudFront KeyValueStore resources in the CloudFront console or using the CloudFront API/CLI. As part of this launch, CloudFront is also introducing a new runtime for CloudFront Functions, called cloudfront-js-2.0, which is required to enable KeyValueStore. This new runtime ...
What protocols are used in IPsec? In networking, a protocol is a specified way of formatting data so that any networked computer can interpret the data. IPsec is not one protocol, but a suite of protocols. The following protocols make up the IPsec suite: Authentication Header (AH): The AH...
How does Amazon CloudFront handle query string parameters in the URL? Can I specify which query parameters are used in the cache key? Is there a limit to the number of query parameters that can be whitelisted? What parameter types are supported? Does CloudFront support gzip compression? Streamin...
